Title: Manky's XS650 Yamaha
Post by: Manky Monkey on May 23, 2010, 11:25:06 PM
This one's VooDoo's fault! He posted the link to it on Ebay in the For Sale bit of the forum.
Just driven half way across the country in a rented van to pick up this little jewel from sunny Lancashire.
A 1980 Yamaha XS650 SE.
The "factory custom" version of the XS. Came with pullback bars, (similar to these but lower), smaller tank, stepped seat & cast wheels. This one has a 2009 tax disc so has presumably been ridden in the last year or so. Looking a bit sorry for itself, but it's got potential.
The clutch & throttle were disconnected & the chain's hanging off, so not rideable, but after 10 minutes of jump starting from a battery pack & spraying bucketloads of "EasyStart" down the carb mouths, it finally fired up & didn't sound too bad. It came with 3 plastic buckets full of odds & ends, some of which might actually belong to this bike.

I just grabbed it while it was there. No huge rush to build it -I'll put it in the shed & just tinker with it when I feel like it.
The plan is to build a low budget bobber/chop.
Cut the back off the frame & hardtail it, stretching the arse end a few more inches. Maybe rake the front end out slightly once it's sitting lower at the back. A Harley Sportster tank & sprung solo saddle. Short rear guard. Strip & polish the aluminium wheels. Add gaiters to the fork legs. Flat bars. Standard position footpegs. Long straight high level exhausts down the lefthand side. Gloss black frame & a big bucket of gold metalflake on the tank & guards.
Just something to blat around on on sunny days.
It was on Ebay with a Buy It Now price of £795. I made an offer of 600 & we agreed on 650. It wasn't in a rideable condition though & only seemed to run on a constant stream of Easy Start, (actually the can was called "Start Ya Bastard"!). Might just be out of fuel, who knows. The battery's dead or the charging circuit's not working cos there was no power there at all other than the Jump Start thingy.
So we settled on 600 quid. Less than 2 week's wages.

I'm seriously thinking of going "legit" & putting it in for the SVA registration test once I've cut & reworked the frame. Don't know anything about the bike test so will look into it & see what's involved.
That "sissy bar" & ape hangers have gotta go!

Bars & backrest binned. Lookin' better already!
I'll strip it down, cut the back off the frame, then start mocking up the look I'm after.
Not taking precendence over all the other projects, just something different to play with.  :)

Will you never learn!  ;D
On the plus side though, its nice to have "something different" to do every now n then, i find it can kick start a struggling interest in whats allready going on.
Andy, if you are getting rid of the bars, i`ll happily swap them for a few quid with you  ;)

Post by: tazet on May 24, 2010, 07:23:23 AM
The guy wanted over 700 quid for it but because of the state and condition of it Manky managed to knock him down to 600 and it was paid cash on the spot. Have sent him a text with all your requests for the bits and yes they will not be going back on so they will be up for grabs. Will measure the sissy bar in a bit for ya Doc and when he took it off one of the mounting tabs broke or atleast was already broken but should be able to re weld it back on.

Post by: Manky Monkey on May 24, 2010, 04:46:11 PM
How about I put the sissy bar in the middle of the carpark at Pete's show this weekend & you lot can fight over it.  :D Not into that whole 70s look myself, so you're very welcome to it.
Twisted, you asked first, so you get first refusal.
It mounts to the top shock absorber mounts & also bolts through the rear mudguard. One of the mudguard tabs has snapped off, but they don't show so you could carefully re-weld it & touch the chrome in with paint. I've got the tab.
Yours for 15 quid? Will offset some of the diesel costs to drive to Preston & back! If you're at Pete's New Forest show I'll take it along.
Measures 11 inches between the shock mounts & stands 23 inches tall.

I'll go measure up an let you know, I will be at Pete's do on sunday.

Yep it'll fit so I'll have it thanks but if it don't fit for some reason will pass it on to Nabsim

Post by: Manky Monkey on May 24, 2010, 04:52:38 PM
Okey doke.
Handlebars are no good I'm afraid chaps. Didn't notice when they were on the bike, but they be bent. So I'm assuming there's been some bike/tarmac interfacing going on at some point.
I need some long straight sections of 7/8" bar to step down the ends of Taz's trike bars, to take Japanese switchgear. So I'll cut 'em up for that.
Bobbi, yeah, the Pop still comes first as it's on a deadline, followed by the trikes, followed by this. Taz's muscle car is on a whole different time scale!
Like I said, this is just something to mess about with when I feel like it -might throw it together really quick, or spend years browsing autojumbles for just the right bit for it. Who knows.  ;)

Received a pair of 10mm thick mild steel axle plates in the post today. 29 quid from Cycle Haven in Lincolnshire, via Ebay. They come with a 20mm slot for the wheel spindle, allowing chain adjustment, cut outs for the hardtail frame tubes to fit into & mudguard strut mounting holes.

Not planning on selling mine just yet.
My new fuel tank arrived today. Actually, it arrived yesterday, but I was at work, so it was re-delivered to Taz's workplace today. 2.8 gallon low tunnel Sportster copy.
I couldn't decide between low or high tunnel, standard Sporty or the wider King Sportster. In the end the choice was made for me when Angie at Cycle Haven said she had this one on the shelf for 89 quid. It's a low tunnel, so will sit high on the frame tube.

The moment when "Oh my Gawd, what have I bought" turns into "Oh my Gawd, what have I done".
Started stripping the bike down in the shed this afternoon. Good job I hadn't planned to ride it home. The swinging arm, shocks & rear wheel spindle were only bolted in finger tight. The guy I bought it from was a bit of a Del Boy type, buying & selling all sorts of stuff. He had a yard full of building materials & small plant. He said he'd taken the bike in part exchange. Looks like it must've been in boxes & just thrown back together & slapped over with some black paint to flog it on.

Might fit the big chrome headlight to Taz's trike, but got a set of XS guages for sale if anyone wants them, plus the swinging arm -not much use to me in a hardtail.
I remember my previous XSs had 2 seperate coils. This one's only got a single, twin lead one, so presumably not standard. I started off trying to keep the various electrical components hooked up to their respective connectors so I'd know how it goes back together, but eventually gave up & just ripped it all out -it'll need simplifying & re-wiring anyway.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 31, 2010, 10:51:42 PM
Started cutting away the back end of the frame -yes Archie, before you say it, I will be losing the huge sections that held the swinging arm pivots, brake pedal, footpegs etc, but am trying to figure out alternatives for it all before cutting it all off.
Past the point of no return now.

Post by: Manky Monkey on June 01, 2010, 10:42:12 PM
VooDoo- yes please. PM me with a price & I'll try & meet up with you somewhere soon.
Archie- I'm hanging onto everything for now -just in case!
Clive- consider yourself shouted when the time comes. When I pulled the electrics apart there were several "black boxes", none of which mean anything to me. Never understood leccy stuff.

I used Archie's chop frame to model my new Sportster tank today. Having blown 80 odd quid on it, I'm not sure now. Archie's is a high tunnel Sporty tank, so sits low over the top frame tube. Mine's a low tunnel so sits high on the frame. I think I prefer the high one. Any opinions?
Archie's high tunnel.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 01, 2010, 10:42:52 PM
My low tunnel.
I think it'd need a lot more rake on the front end & less stretch on the back end for it to look in proportion.

Back wheel in roughly the same position as the original swinging arm set-up. This produces a straight line from the headstock right down to the rear wheel spindle. XS650s have quite a high headstock, giving quite a chopped stance already when you remove the standard tank.

Post by: Manky Monkey on June 03, 2010, 11:37:34 PM
Just under 6 inches of ground clearance here, so I can afford to lose one or two. That'd mean cutting the headstock to rake the front end out a little. The engine's leaning back a touch, so raking the front would bring it back down level.
Comparing mine to Archie's current XS build, his has a 17 inch rear wheel & dumpy "Upside Down" sports bike forks, whereas I have a smaller 16 inch rear wheel & longer original Yam forks.

wrong way round tbone, he would need to shorten the tubes to lower the front of the bike as the engine is leaning back . go on rake out the front end and slam it to the ground , just go on runs that miss speed bumps

yep thats what i said keep its standard and short tubes lowers the front bringing the engine forward , or rake out the stock and use appropriate tbes to level it of with the rear wheel shaft so the lower tube is level

I've got part of the trike exhaust in the vice at the moment, cleaning up the spring tabs, ready to trial fit it again & I spend a couple of hours working on the Pop every day -so there!
I'm gonna go with increasing the rake to bring the frame level I reckon.

I bought a reproduction 1937 ...something, tail light at a rod show at the weekend -Chevy? Ford? Not sure.
It's quite big. The lens is about 3 inches across, but I liked it. Loony found an old "bullet" chrome wing mirror in the workshop & the plinth from it would work quite well as a light mount. Maybe too big to sit on top of the mudguard? I guess I could sink the end into the rear guard so it looks less obtrusive, but I kinda like it's quirkiness. Could bolt it to the hardtail as a side mount, but I'm not keen on side mount number plates. Wonder if it's SVA compliant to have the light offset on one side of the frame, down by the rear axle, with the number plate on a seperate bracket off the bottom of the guard?
Modelled here by Mr Lunatic on Archie's XS.

Post by: Manky Monkey on June 11, 2010, 10:06:39 PM
My day off today & Taz is away for the weekend, so I had a bit of a road trip, all by myself.
Drove up to Lincoln & back to visit Cycle Haven. Angie & Nic have been running the business for ...Gawd knows how long. I was buying chop parts from them about 25 years ago, so they must be one of the longest running custom bike shops in the country by now. Very nice people.
One of the first trikes I ever saw, & the one that inspired me to have a go at building my first, was Nic's low riding XS1100 Yam. I saw it at the Bulldog Bash in Stratford on Avon back in the mid 80s. That looks so simple & tidy I thought, I could do that.
Amazingly, as I walked through the door of their shop, I saw a familiar shape under a cover in the middle of the showroom -that's not the old XS11 is it?
Yup. Apart from a change of forks, it's still exactly the same as I remember it. 
After a 4 1/2 hour drive there, they made me a cuppa & I perused their shelves.
Having decided the low tunnel Sportster tank I'd bought mail order from them just didn't look right, I took it back & swapped it for a high tunnel, the later model with the screw in cap. That'll let me fit a pop-up flush mounting cap for the SVA test. I think a standard chrome cap will suit the chop more though, so bought one today & will pinch the pop-up one from my trike for the test.
I also bought a tap, a pair of flat drag bars & some vintage style grips. Trouble is, the grips aren't availbale in 7/8" Japanese bike size, only 1" Harley size. Can anyone help me out with some steel or nylon reducer sleeves? 


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 11, 2010, 10:10:09 PM

All in German.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 11, 2010, 10:19:44 PM
I also ordered a few parts that weren't in stock.
A 5 1/2" side mount Bates headlight -"nobody buys side mounts any more. They all go for bottom mounts". Not me. I'm keeping the original Yam yokes so will make some 6mm rod brackets to fit between the top & bottom yokes to hang the light on. I might cut down the Yam headlight brackets to make plain sleeves to cover the fork tubes between the yokes.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 11, 2010, 10:21:16 PM
Also on the shopping list was a chrome mini speedo.
A pair of black rubber fork gaiters.
A pair of seat springs.
And a pair of bar-end indicators, though I'm not sure I'll use them yet.
I'd hoped to get some custom footpegs but all they stock for Jap bikes is the chrome & rubber "SunDance" style, which ain't really my thing. So I'll try to find some replacement rubbers for the original Yam pegs.
That little lot should give me enough to be able to get the bike into the frame jig PD & Loony made when it's available & start putting together the hardtail. 


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 12, 2010, 10:54:45 PM
Messing about in the shed again this evening-
new fork gaiters fitted. I wanted a short, chunky looking front end, rather than long skinny forks. I also tried the standard Yam chrome fork shrouds. Fitted upside down, they hold the side mount Bates headlight more or less where I wanted it, so I think I'll keep them. As always, I'm hoping to re-use or adapt as many original parts as possible on this build, partly to save money, but also cos I think it's kinda cool to give old parts a new lease of life. Re-cycling rules!


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 12, 2010, 10:58:57 PM
New solo saddle also propped in place. Not cheap, but just a bit different from the usual Highway Hawk ones & despite it's minimal padding, very comfy. It's slightly wider & longer than the Hawk ones & will sit on 3" "Hairpin" or "Scissor" springs.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 12, 2010, 11:02:02 PM
I've had forward foot controls on chops before & always had problems with the long linking rods flexing or the footpeg mounts bending etc, so will be re-using the standard Yam footpeg/pedal set-up.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 12, 2010, 11:08:32 PM
Rather than running a straight line from the headstock, right down to the rear wheel spindle, I'm going to mate the top seat rails to the bottom of the top tube an inch or 2 lower, so that when the seat's on, it'll flow from the back of the tank, rather than being perched up high above the frame.
Still planning on a gloss black powder-coated frame, with heavy gold 'flake tank & guards. I'll run 2 long straight, high level exhausts down this lefthand side, finishing level with the rear wheel spindle. Still looking for a pair of finned cylinder head exhaust clamps if anyone has any.

Mankey - I’m interested in the original tank if still up for grabs, maybe the clocks too.

Bike looks like it could be pretty cool when done, nice old lumps the XS650, the grass track sidecar boys take them out to silly sizes and they just hang together. For the solos, there’s a bit of bracing to stiffen up the area around the swing arm mount, and then the frame does the grass track (or American flat track) biz no sweat.


The site Archie mentioned on June 10 (www.xs650shop.de)
is a European outlet for a place in the States called Mikes XS. They do some replacement parts along with some nice goodies.
Mikes XS also have a place called Heiden Tuning (www.xs650.biz) in the Netherlands but it seems both the European site’s websites don’t  show all the stock that the US site shows (if that makes sense).

Am aware of a guy with a ‘76 650 with a 750cc 270 degree motor and spoked wheels making a street tracker, should be interesting.

Cheers all

Tony

Hiya Tony. I've got the clocks on the shelf in the shed, but the tank went to PD. He might well be up for selling it though.

Haven't even opened the door of the shed for weeks. Ventured in there this morning & it's full of cobwebs & has that musty, damp smell, (the roof leaks like Niagra Falls).
I finally picked up a pair of finned exhaust clamps from Ebay a couple of weeks ago & also bought a pair of 930 Amal concentric carbs. The guy I bought them from was very nice on the phone, but lousy at shipping stuff out -I Paypal'd him the money nearly 5 weeks ago & they finally arrived this morning. I was on the point of contacting Paypal. Although my particular carbs weren't advertised on Ebay, he sells stuff there regularly, so I wasn't sure what I could do to get my money back.
Anyway, they've arrived safe & sound & he threw in a set of gaskets, plus fitted the correct size main jets for me, so I'm happy. No real reason for switching from the standard Mikuni vacuum carbs, other than I'm old fashioned & like something mechanical that even I can understand, that's easy to adjust & which I can buy new repair parts for if necessary -plus I think they look cool. Burlen Fuel Systems, who still make Amals as well as the SU carbs fitted to Reliants, sell polished aluminium bell mouths for these. They also do cast aluminium ram pipes,, which I'll probably go for, just cos I think they look better.
Still waiting for Loony's frame building jig to become available, but I'm quite looking forward to tinkering with this project over the Winter.

Post by: Tony oily bike on October 08, 2010, 12:06:03 PM
Cool.

Putting on a couple of 'real' roundslides as opposed to the old CVs sure makes the old XS look better (older/more traditional), and makes fettling a whole lot easier!!!!
Plus all the bits are so easily available for the amals too.

About to change my XS's CVs for a pair of Mikuni VM32s which ironically is what comes in replacement kits for ’69 – ‘78 Bonnies replacing the Amals, (maybe that's where your chap gets them from!!)

Depending on the space available, changing the inlet trumpet’s length will change the engine chracteristics (low down torque or top end oomph). Good old Phil Irving explains all in "Tuning for Speed".

Hi. I like the way the tank looks in bare steel. Ive started to make my own seat pan which i might be selling on the good old ebay soon.I will try and get some pics on at the weekend.They will be the basic pan shape similar to your seat,but made in stainless steel with a swirled pattern edge,to give it a hot-rod look about it.Then a smaller piece fits over the top,which can be padded.When you see it you,ll know what ime on about.

Just collecting parts at the moment. Haven't built a chop for decades. I want to keep it real bare-bones simple -no electric start, nothing it doesn't need to make it go, stop & point in roughly the right direction.
Seat sounds interesting -I'd like to see some pics of that.
Mr Oily- I'm only fitting trumpets for the looks -so which is better for normal road use -long or short 'uns? (found me a buyer for that pair of 26 mills yet?   :)  )

Mr Manky sir, re your Trumpets.

Today, you should be mostly using............................. long trumpets (for low down power)


Shorter trumpets/velocity stacks are for the higher rev range.

Whether you'll actually notice any difference is perhaps a different matter

Just had a visit from PD & Big Darren.
Pete's been desperate to find a cheap XS650 to play with for ages, but seems cheap ones just don't exist any more -which is why I snapped mine up for £600 quid from Ebay when I saw it.
It's been sat in the shed ever since cos I just don't have time to build the little single seater bobber/chop I want.
Solution: farm the project out to Pete.
I've got most of the major components I wanted -Sportster tank, flat drag bars, Bates headlight, sprung solo seat, Amal carbs etc. Loony's already lined up to spray the tank & guards in 60s style heavy metalflake. Probably in a colour called "RootBeer", a sort of golden brown, like Coca Cola -appropriate as I'm known for drinking gallons of the stuff. Maybe we could name it in 60s fashion too -"The Coca Cola Kid"? It needs a hardtail making up to graft onto the original engine cradle then all the bits hung in place -easy! So we loaded all the bits in the back of Darren's van & they're heading back to Pete's place with them as we speak.
I just want a simple little chop to blat around on. Never had anyone build a custom for me before, but I trust Pete's artistic eye & he'll consult with me along the way so it doesn't stray too far outside the overal look I want. I'm curious to see what he comes up with. We'll keep you informed.

The spindle's 20mm, but Pete'll have to measure the frame rails.
I visited his vast fabrication workshop this evening for a consultation on my XS build.
"This alright?"
"Yup".
"Seeya".
I've got a good idea of what I want the bike to look like, but want to give Pete enough freedom to put his own mark on it.
Can't wait to see the results.

Pete's little bro Ryan's taken up pinstriping & has tried a spot of hotrod flaming on the XS's original fuel tank.

An update from Pete.
I wanted to build the hardtail from 1 inch bore ERW -the same stuff we build our trike frames from. Some thought that'd look too heavy, but I think it works. After another quick consultation with the customer, (that's me), Pete's taken 1 1/2" out of the length of the bottom tubes & bent the top seat tubes.
I likes it.

I didn't measure it -simply mocked up the parts in my shed until they looked right. I'll get Pete to have a measure up for you.
Another visit to PD's Palace of Mechanical Delights this evening, this time with Loony in tow. He's also building an XS for someone else, so was checking out the competition & comparing notes.
The frame out of the jig & rolling -I'm really pleased. No photos of us onboard it, but I can report it's a very natural riding position & feels like it'll be a lot of fun to ride. We want to keep it simple & useable. Pete's aiming to work on it as much as he can in the next few days before we put it on show on our pitch at the Basingstoke Festival of Transport next weekend.

The first bike I ever rode on was pillion on my mate's CB500T. T'was a metallic brown one. Another mate had the bright orange version with huge apehangers on. They were the blokes who introduced me to the bike club I joined when I was 17 -so always had a bit of a soft spot for the 500Ts. Much under rated bikes I think.

I dropped in to see Pete today. He's got my MIG welder on long term loan to build the XS with, but I needed to borrow it back for a day to weld the stainless exhausts on my truck.
He showed me his progress -he's started tacking together some manifolds for the mark 1 Amal carbs I wanted to fit. Must admit, the main reason for using these is to make the engine look a little more British & classic. I reckon they'll look great. Pete's angled them out to follow the line of the seat rails.
He's also started work on a shallow electrics box under the seat, as well as making up a cross member for the seat springs to mount to.
Lookin' good Pete.  ;)

To enhance that British/Classic look, simply damage gasket sealing faces and oil seals prior to assembly, that way, the external corrosion protection system can come into play, giving your pride and joy a new lease of life as a pseudo Brit and adding longevity to components that may be prone to suffer from corrosion.  :D

As far as I know Terry  :)
Haven't seen Pete for a while. I gave him as free a hand as I could to build the bike on my behalf & supplied him with the components I'd already bought & a rough idea of the overall look I was after.
I bought the donor bike on an impulse from Ebay after being inspired by Archie's XS. I've had 4 or 5 of them before & had forgotten how nice a bike they are. But it would've sat in my shed until I get the time to build it, so any progress PD makes is better than none. I'd really like to get it on the road for the Spring & after all the work & headaches we've had with my truck build, putting a bike together seems childs play now -but I'm not going to breathe down Pete's neck about it. It'll be ready when it's ready.
But I will contact him & see how it's going.  :)

Be carefull when buying projects off ebay that state "few bits needed to finish".

This poor chap got caught out when he bought his XS650 project. The box of parts that came with the engine did feel a bit light.

O.K, time to catch up with this one.
Regular readers will maybe remember I bought a tatty XS650 two years ago, plus a pile of off-the-shelf custom parts. The plan was to put together a basic little "bobber" at some point, whenever I got the time/money/enthusiasm.
Enter PD. Pete fancied building an XS chop but couldn't afford one. So I farmed mine out to him, to build on my behalf. He built a jig & hardtailed the original Yamaha frame, fitted the sprung solo seat, made a start on the battery box etc.
Eventually he lost his building mojo & the project came to a halt again.
So Big Darren collected it yesterday in his van & delivered it today to Loony's workshop. Loony's a big fan of ol' school chops & shares similar tastes to me. He's hoping to take his bike test soon, but in the meantime, looks like he's got an XS to play with.

I'd intended to take this home & put it back in the shed at the end of the garden until I had the time to play with it, but it got hijacked & delivered to Loony's place instead.  :)
I don't want to get side-tracked from completing my Pop, but having built an entire truck from scratch, a bike looks a lot simpler & quicker to put together now!
With it in the workshop, Loony & I have already begun bouncing ideas around. Looking forward to blatting around the lanes on this.
A heap of bikes in the corner of the 'shop. My XS650, Tom's XS650, (up on the bench), & Loony's own Bantam -& his Mum's bicycle.

Loony's Dad's just taken delivery of a new mill for the workshop, which takes up most of the space where the bikes were stood. So no sooner had the XS arrived than it'll be going again. Gonna dismantle it over the next few days & transport it back to my shed as it's only in the way & going to get damaged where it is. Not gonna get distracted from the Pop, but it'll give me something to tinker with when I need to wind down.

Always liked the look of the xs650s, they looked the part. The old xs1 and 2s were quite a good looking bike in their own right back in the day but they handled quite bad until they fettled the frame by gusseting it here and there in the later models. . My mate got his nearly new xs2 and ground up all the frame welds and re welded the whole thing tidy, it did handle better than before too.

Post by: Manky Monkey on August 03, 2012, 09:54:27 PM
This is my 5th or 6th one over the past 30 odd years. People used to buy them to pretend they had a British bike, but these days they've got a cult following of their own.
Tony Oily Bike lives locally to me & sprint races one, so I'll be asking him to take a look over the engine at some point. I grabbed the donor bike when it came up on Ebay, just to put by for a future project, so it's already further ahead than I'd expected. I'd like to have it on the road for the bike swapmeet in Dorking, Surrey in the Spring.

 As i said my mate got a near new xs2 650 back in the late 70s we were still on Tiger TR7Vs and trident T150vs  . I was sort of shocked when he showed up with it, but i actually liked it, apart from the handling. Another jap twin i never owned but a mate did was a Kawasaki Z750 that was heavy from what i could remember. but ran well enough.

Stripped the rolling chassis down & got everythng except the frame & engine in the back of my car. So it's back in my leaky shed for now.
As I said, not going to forsake my truck project for the bike, but will quietly potter along with it when I get some spare time, (ha!). I'm aiming to have it roadworthy for the Dorking Harley swapmeet, about 10 miles from home from me here in Surrey, in the Spring.
I've been thinking about mudguards. I want to fit a ribbed rear one, similar to those on my truck. They're the "in" thing to have on chops & bobbers at the moment to give a more classic look to the bike. I'm using the original Yam' 16" rear wheel though, whereas most "bobbers" use taller, thinner wheels, often with skinny crossply tyres. So the guards I've found are the wrong diameter or too narrow. Not cheap either.
A quick email to the guy in Oxford who made my truck ones & he says yes, he can make me a pair for the Yam & take them with him to the Beaulieu autojumble next month. That's handy. So I'll measure up tomorrow.
He makes aluminium bodies for vintage specials. Check out the photos here:

Bought these little beauties at the local Popham airfield MegaMeet bike show this weekend.
A pair of aluminium bellmouths for the mark 1 Amal carbs I'm going to fit. Turned from thick walled tube.
Ooh, so-o-o shiney. Lookit the pretty things. No. No you can't touch. They're mine. All mine. My preciousess. 
Managed to buy the wrong size though, (600 series instead of 900), so after trying them on my carbs back at Loony's workshop, I had to dash back to the show & change 'em. Fortunately the stall holder was still there.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on September 19, 2012, 10:21:14 PM
We've loaded the XS frame & engine into the back of my pick-up truck at Loony's workshop -partly to create some more space & partly so it's at a workable height for him to weld it.
I want the newly hardtailed frame to look like it left the factory like that. We talked of adding fake castings or mounting lugs to it to make it look "factory". So we've borowed an idea from a rigid framed Triumph in Back Street Heroes magazine & capped the ends of the frame rails with stubs of tube mounted sideways on. These are actually the threaded collars that come on the ends of the lengths of ERW tube we build frames from. They don't do anything at all, but look like they must be there for a reason.
PD, who built the hardtail in a jig in his shed, left the frame tubes overlength as he was unsure how to finish them. I was worried the new back end of the frame would look too long & "stretched" compared to the engine cradle. Shortening PD's tubes & adding the lugs makes it look dumpier, which I like.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on September 27, 2012, 08:43:08 PM
All 4 lugs added to the axle plates.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on September 27, 2012, 08:56:45 PM
Front gusset, between the 2 down tubes, extended by a couple of inches to meet the new tubular brace.
The old one was hidden by the original fuel tank & held the ignition coils. The new one sits parallel to the ground when the frame's on it's wheels & is made from 1" bore ERW tube.
Triangular plates added to fill gaps in the headstock gussetting.
Top yoke de-lugged & smoothed.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on September 27, 2012, 09:06:36 PM
A few odds 'n' ends to tidy up, including sleeving the bottom tube joints, then the frame will go back in my shed, just to get it out of Loony's way, until the mudguards turn up.
Been waiting for them for a few weeks now. No real rush, but I need the rear one to set up the seat mount, mudguard mount, sissy bar etc.
Pleased with the frame so far. The large diameter tubing of the hardtail matches the diameter of the front down tubes, which are actually double skinned. It now looks suprisingly short & chunky.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on September 27, 2012, 09:19:54 PM
The seat tube, (the red oxide coloured one), will be replaced, so no point fully welding it.
The front tank mount can be added, but the rear one needs a tube machining. I could add the footrest mounts, but they'll require the engine back in the frame.
So for now, this is about as far as I can get.

I'm on holiday this week, but Loony's got 3 cars to paint, so it's all a bit manic in the workshop -best I keep out of his way.
So not much I can do really. Had a phone call from the mudguard guy to say he's making several sets of wings for vintage cars this week & will do mine too, but he's lost the letter I sent him with the measurements. Fortunately I'd kept a copy & have posted it to him. So might have some ribbed guards to play with soon.

Collected the mudguards from Darren at Brooklands Bodycraft near Oxford this afternoon. He builds aluminium bodies for vintage race cars & turns out some lovely work. He rolled these guards from flat ali sheet & hand punched the raised beads to match the ones he made for my truck.
Made to my measurements, £100 for the pair.

I asked if he had plans & dimensions for the various body styles. He said his customers supply him with a chassis, (in this case a 6 cylinder, 2 litre AC engined beastie),

http://www.ac-6.co.uk/

& he builds a car around it to suit their requirements, driver's size etc. So it's all done more or less off the top of his head. Beautifully done.

Post by: Manky Monkey on October 13, 2012, 08:39:02 AM
Tried the rear guard in place on the bike when I got back to Loony's place. I had it made deliberately overlength, cos I'm not sure how long it needs to be at the front end, (the bit under the saddle). It may well be shortened. The seat will be lower at the back, but I need the guard in place to decide by how much.
I think it's quite cool that my truck & my bike will have some parts in common.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 13, 2012, 08:42:43 AM
When PD hardtailed the Yam' frame, he covered the saddle in an old T shirt to protect it from welding spatter. Unfortunately the chrome springs & front mount have been spattered, so will need filing off & re-coating. These "hairpin" or "scissor" seat springs are normally mounted the other way round, poking out the back of the seat, but I prefer them tucked underneath, so the back end appears almost unsupported. They should still work just the same shouldn't they?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 13, 2012, 08:51:41 AM
The front forks are at home in my leaky shed, so I tried the front guard on them this morning.
You can buy steel versions of the ribbed guard design from some of the custom bike shops, but only rear ones & only in large diameter, skinny width. They're popular with the guys building vintage style "bobbers", who often run tall, skinny crossply tyres. Looks like all the shops order from the same supplier though cos no-one's got any in stock. Plus I'm using a fat 16" rear wheel, so needed a wide, small diameter one.
A lot of bobbers don't use front guards & they don't seem to be available off the shelf, but I thought if I'm having a rear one made, I could have a matching front one, just to be different. It's a thin, tapering blade. I'm really pleased with it.
The steel rear guards, probably stamped out in a Taiwanese factory somewhere, cost up to 90 quid. I paid 100 quid for my 2, made to order, ones.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 13, 2012, 07:14:19 PM
Keeping what I've got.
Mine was the SE model, basically for the American market, with fat 16" rear wheel, stepped seat & pullback bars. I've always liked these mag' wheels.
I'm not really going for the traditional "bobber" look, but more of a sensible, rideable chop with bobber influences. No clever engineering, just something cool I can jump on & blat around the lanes on, on sunny days.

Started bending up a pair of rear mudguard struts from a length of 10mm steel rod, picked up for £1 from the local scrap metal yard.
I plan to mirror these with a pair on the front guard. They'll eventually be chromed.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 27, 2012, 09:55:29 PM
Made a pair of tabs that bolt to the original mudguard mounts on the fork legs, then bent a pair of 8mm rods to form the front hoops. They need to be a bit closer to the tyre, but summat like this.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 27, 2012, 09:59:56 PM
Then I started cutting a sheet of heavy guage steel for the seat base. Loony preferred to leave this area open, but I plan to mount the electrical stuff under it, so don't want it all being soaked by rain etc. The seat springs will mount to the back edge & I'll add a mudguard mount underneath. Then I'll cut an access panel in the middle. A bit more trimming & it should drop into place so Loony can weld it along the centreline of the seat rails.

Cheers. They're only propped in place at the moment, (Mr Lunatic's going to get some lathe practice by machining the mounting lugs to bolt them to the frame).
The seat panel's actually quite complicated, with an access hole cut in it to reach the electrics that'll be underneath, a flange cut to form a lip under that hole, a lid cut to sit in the hole, on the lip, recesses cut for the Dzus fasteners to hold it shut, a curved tab under the back edge to hold the front of the mudguard, a suspended platform underneath to house the electrical components -not a 5 minute job & needs a bit of thinking about to get it right.
Mike, I do actually do an 8 hour shift at work every day before going to the workshop you know!  :P


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 31, 2012, 10:16:09 PM
Access hatch cut in the seat base.
This will give me access to the electrical components. Rather than housing them in a sealed 'leccy box, they'll be bolted to a platform mounted below the seat. Removable side panels will give side access as well -I've learnt from past experience that it'll always be the component in the unreachable far corner of the box that wil pack up in the dark & rain on a country lane in the middle of nowhere. Not being inside a closed box will also stop things from over heating.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 31, 2012, 10:19:45 PM
Parts made to produce a flush fitting lid to the panel.
The corner pieces will be spot welded to the underside of the flange to hold the Dzus fasteners. The flange will then be welded under the main panel. Hopefully the lid will then drop in on top & sit flush.

Post by: Manky Monkey on October 31, 2012, 10:22:37 PM
Electrical components.
The bike was running when I bought it, but I ended up just pulling the bodged up loom apart & throwing everything in a box, along with a few spare bits that came with the bike.
So without going into too much detail, can anyone tell me which components need to be mounted close to which other components in my box?

Ignition unit. I know that's what it is cos it says so on it. What does this hook up to then? I've had several XSs before but have never understood vehicle electrics.
I'm a creator -I can build a vehicle around an engine, but when it comes to making it go, I tend to seek the help of those more mechanically minded than me.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 31, 2012, 10:31:25 PM
Rectifier/regulator units.
I know they take the AC current from the alternator & turn it into a steady 12 volt DC supply, losing any excess in heat, through the fins. So I plan to mount it under the electrics panel in the air flow.
One came with the bike, 2 were spares. No idea which is which -is there an easy way to test them?
I assume the round thing, bottom right, is the starter solenoid, which I don't need as I'm blanking off the starter motor & going with kickstart only.
What's the other unit, top left?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 31, 2012, 10:36:45 PM
The engine's also got one of these hanging off it by it's wires. Boyer electronic ignition. So what does this connect to?
I also need a fuse box & probably an indicator flasher relay as I'll more than likely put the completed bike in for MSVA. Nobody seems to bother testing bikes, but surely if you've chopped the frame in half & added a hardtail, it should be MSVA'd as a new build?
Bikes don't seem to have headlight or other relays. The ignition switch will go in a seperate housing next to the battery.
Anything else I'm missing?

Post by: Olds on November 01, 2012, 07:38:45 AM
Try this
http://raskcycle.com/
tech tips, wiring diagram
Agreed , if you alter the frame it should go for MSVA but you may be able to keep the original registration number if engine and frame numbers match the V5
Bikes generaly don't need light relays as the headlight is often 35w not the 2x 55 or 60w of a car.

An electronic conversion, if you can get me the number on the unit we can sort that too.
It`s the box no. we need, so it`ll be BOX000??,  numbers, not question marks  ;D, probably 10.
Ah, just re-read some of this and your scrapping the starter motor, these electronic conversions dont work great with a kick start system.
You`ll need to check wether or not you still have points fitted, chances are they will have been thrown away, including the base plate & the advance unit.


Title: Re: Manky's XS650 Yamaha
Post by: Dslam on November 02, 2012, 07:44:24 AM
I have used these on my race bikes for years with little problem. There should be a stator plate where the points used to be. Probably under a cover at the end of the cam (not too au-fait with Yams) It is a circular PCB type material with two small hall effect coil bobbins and a magnetic trigger on the end of the cam. This picks up the trigger signal and converts it to 12v switch for the coils. The type you have is quite elderly but should be OK. If not they are not wildly expensive to replace. The only down side is the advance curve programmed in is designed for a Brit twin and may not be suitable for the XS. Really easy to wire up as the instructions are on the box pictured. ;)

So should that early type voltage regulator be used in conjunction with the finned rectifier, or is the finned one a later, combined unit? The donor bike came with a pile of spare bits. Stupidly, I stripped it down & chucked eveything in the same box -so now I don't know what was fitted & what wasn't.

O.K Tel.
Experimenting with side panels. PD cut these curved panels from an old Calor Gas bottle when he had the bike to build the hardtail. I like them, but not sure how to mount them yet. Probably going to hang a platform from the underside of the seat base plate, to bolt the electrical components to, then slip the 2 side panels, welded together in a V shape, up over it & hold them with more Dzus fasteners.
These aren't very deep so I might have to mount the regulator/rectifier unit on the back of the battery box, although I may extend the panels to make the box a bit deeper.

It`s a good thing that the XS 650 is very much based on the BSA A65 Lightning so that boyer ignition will work fine. Not too sure but if you put a capacitor/battery eliminator into the system (we always used to use big blue ones sitting inside a spring for mounting) then it should make it easier to kickstart with that ignition setup, just kick it over a couple of times with the kill switch off but ignition on, that puts a charge into the capacitor which will be used to power the electronic ignition on the initial kick over (if I`m wrong i`m sure someone will correct me).  ;) ;) ;) ;)

Not sure how deep I can make the 'leccy box, so I've been playing with the battery box that'll sit underneath it.
When PD hardtailed the frame he also put together a little battery box. Nicely done, but it needed a lot of finishing & I wasn't entirely sure it was my taste,. So I've quickly folded up a sheet of scrap steel to form a box & Loony's glued it together.

Hi Andy,

On your bike, the RHS end-of-cam cover would have had the advance/retard bobweights with ATU shaft running to points plate at the other end of the cam, but as you're running electronic ignition, the bobweights are no longer needed as the Boyer electronics has a pre-mapped curve, Triumph/BSA twins in your case.

My XS650 runs Lucas electronic ignition, lifted from a T140E, works fine, though the Lucas system is more susceptible to reduced voltage than the Boyer system, so my personal preference of one over the other would be to have the Boyer.
I haven't been aware of any issues with respect to the advance curve being set for a Triumph.

I've phoned the guys at Boyer as I had big issues with my ignition a couple of years ago and thought it was the electronics (Lucas) and was going to throw it away and go for Boyer. The chap was incredibly helpful  ;D, and suggested doing some tests first, as opposed to selling me a new system!!! I did the tests and kept the Lucas. So I can't sing Boyers chaps' praises high enough.  ;)

My bike's problem turned out to be the original coils – they were breaking down when they got warm/hot. Testing had suggested the electronics (no spark with good plugs), so when Dslam and I put a borrowed replacement Lucas box-of-tricks on, it worked (because by then the coils had cooled!!). So don't always believe what you see..............

The coil replacement route I took was to fit a 12v twin-output Green Dynacoil, mounted where the originals were. The spark is superb. Downside is cost, a new one can be around £100. I found an un-used one at a bike shop for £40 and snapped it up.
Its runs a wasted spark too, as per the Honda coil Dslam uses on his sprint bike. In full agreement with Dslam about the plugs, NGK V or EGV, them be good.

The unit I have is a Boyer (Power Box) for use with a 3 phase permanent magnet alternator and has a footprint of about 3 1/2” square (85/90mm square).

The XS650 has an excited field alternator fitted as standard, which means the magnetic field is generated by battery voltage instead of permanent magnets.  If you have a weak battery, you get a weak field, and weak spark, and hard starting, so I'm planning to swop the alternator at the same time – have a peer

So- bearing in mind I'm putting this bike together on the cheap, using as many original, (cheap), parts as I can, & want it to be reliable enough for a Summer get-to-work bike if needed, just what components from my pile of bits do I need to squish into the box?
I'm happy to stay with the standard battery set-up & have already made a container for said Batt'. Is the twin lead coil I photographed O.K?

Twin lead coil.
Not the original Yamaha fitting, (it should have 2 separate ones), but was on the bike when I got it. Will this be O.K or should I buy the proper jobbies? (available new from YamBits).

I'd keep this unit if you're gonna run the Boyer. From memory, both the Boyer and the Lucas prefer a single coil as opposed to twin-coil original set up. (single coil will be wasted spark, which should be no problem).
Suggest you mount the coil somewhere near the original position, thus keeping the HT side of things away from the relatively sensitive electronics.

Ignition unit. I know that's what it is cos it says so on it. What does this hook up to then? I've had several XSs before but have never understood vehicle electrics.
I'm a creator -I can build a vehicle around an engine, but when it comes to making it go, I tend to seek the help of those more mechanically minded than me.

If you're gonna run the Boyer (I would) this Yamaha electronic ignition pack is no longer required.

Looks like previous owner replaced the original Yamaha Transistor Controlled Ignition (TCI) with the slightly elderly Boyer system.

Just for info, TCI was stock only on the later SE/Specials as opposed to the spoked-wheeled models Roadsters which had points.

Rectifier/regulator units.
I know they take the AC current from the alternator & turn it into a steady 12 volt DC supply, losing any excess in heat, through the fins. So I plan to mount it under the electrics panel in the air flow.
One came with the bike, 2 were spares. No idea which is which -is there an easy way to test them?
I assume the round thing, bottom right, is the starter solenoid, which I don't need as I'm blanking off the starter motor & going with kickstart only.
What's the other unit, top left?

I tend to think the top left unit is a relay for the electric start, if it is, you don't need as you're using kick-start only. I could be wrong, as Tbone said it was the regulator, but as far as I know the regulator had the round widgget-thing attatched to it??  :-\

Yep, bottom right is  starter solenoid, which you don't need.

The bigger units in the pic look like they're prob combined Rectifier/Regulators (you'll want one of these!) , but could poss be Rectifiers from early models.

The XS650s changed from a separate Rectifier (to change the AC from the alternator to DC) and Regulator (to control the newly generated DC voltage level) on the spoked-wheeled Roadsters, to a combined Rectifier/Regulator unit on the later cast-wheeled SE/Specials.

The combined unit was mounted on LHS below side panel - it has an 8 way connector with 7 wires.


The older separate rectifier mounted beneath battery carrier (full wave rectifier, 6 diodes) - I think it has 6 way connector.
The older separate regulator was electro-mechanical and mounted underneath LHS side panel - 3 way connector.


Pic of what I beleive to be an old style electromechanical regulator  :-\

Wiring can be confusing, and I'm not great at it, but the best thing is to get your head around each separate 'bit' and what it does, then kinda join the dots of all the separate 'bits'.
So what are the main the bits: Power/battery, Ignition, lighting, charging, etc

Apologies to anyone (incl Sir Manky) if I make this very basic  ::), but we may have some newbies reading this, so here goes......

Power/battery
The bike runs on 12v DC (hence the battery) and the bike would run/function quite happily for a while (so long as the battery had enough oomph) even if the alternator/rectifier/regulator system wasn't on the bike. In fact many competition bikes run this way.
The battery supplies the power for all the ignition, lighting etc to function

Electronic ignition system
The bikes needs sparks from the plugs to run the engine, and these have to be at the correct time with respect to the engine internals etc.
The ignition pack (Boyer/Lucas/Yamaha) is a little box-of-tricks that is powered by the 12v battery. At the same time, the ignition pack also feeds the coil(s) with 12v.

This ignition pack is connected to a sensor on the end of the cam, so when the cam is in the correct position (ie with respect to degrees away from Top Dead Centre of the piston) it sends a signal back to the ignition pack.
The ignition pack takes this signal and says 'its time to drop the 12v I'm constantly sending to the coil', which it does, this then allows the HT (high tension) from the coil to reach the plug, which jumps the plug-gap (old machines had a gap of around 25 thousands of an inch, about the thickness of a thumbnail), and hey presto, the engine fires.(in an ideal world)

The sensitive electronics of the ignition pack are best kept away from the HT cables. In fact, on the XS650, I've heard it said (I think by Lucas??) that the metal cover over the sensor/pick-up is replaced with a plastic unit.

A slight side topic - Coils have different ratings depending on their performance (a coil firing a single cylinder 4-stroke engine doing 4000rpm will be firing 1000 times a minute. If a single coil is on a twin-cylinder 4 stroke at the same revs it will be firing 2000 times a minute)
High performance coils take more power (partially dependant on the resistance of the primary coil, and hence the current supplied by the battery), and as such, all coils generate some heat, so they need to be suitably mounted to allow the heat to dissipate.
Its not uncommon for coils to degrade with age. When they get hot (from use and/or engine heat) they can give up the ghost.

So that's kinda one self-contained system.

Lighting/fuses/relays etc
Again this all runs on 12v DC, so there's a feed from the battery which then distributes itself to things like switches (for horn, headlights, indicators, brake lights, relays etc)

Depending on the bikes age depends on the sophistication of the fuse system. Older XS650s (say from early 1970s) have just one fuse, more modern XS650s (1980s) have a fuse box with fuses for specific functions.
The fuse, fed from the positive feed of the battery (one negative earth machines), is located before the component its protecting, and is designed to blow if too much current tries to flow in the circuit its protecting, thus preventing damage to specific components (and maybe even the wiring). There are different ratings (3A, 5A, 20A etc) so its no use protecting a circuit that will be damaged by 5 amps with a 10 amp fuse. Carrying some spares can be useful !

In general, all the above (and the ignition system) use relativity low current (measured in amps) and therefore do not require relays to be used. A 55 watt headlight uses 55W/12V amps =  less than 5 Amps, that's why most of a loom is made up of a certain size of wire (ie one that can take the required current without burning out)

If there's a requirement for more power, such as a starter motor which can be up to around 300 Amps, the use of a relay is required. The relay uses the standard size wiring to make a switch in a heavy-duty/high-current circuit, which runs using thicker cabling. Its still all 12v DC.
In order to power things like the starter motor, which take a lot of current, a suitably sized battery and related wiring is required.

Charging system
From the above, it can be seen that the 12 v DC battery has a fair bit to do, but it only has a finite capacity, which is where the ability to have a charging system comes in pretty handy (saves carrying loads of 12v DC batteries around!).

If we go back in time, pedal bikes and early motorbikes had a dynamo (remember them?) to produce electricity, and it just happened to be DC as well. To prevent over-voltage from the dynamo feeding the system and frying things like the battery (cos you pedalled really really quickly!), a voltage regulator was fitted, early ones being the famous 'Zener diode'. The regulator generated heat, so was mounted on a heat-sink, often out on the breeze to aid cooling.

One of the down sides of the dynamo was the efficiency, and the dynamo was superseded by the alternator.

Although hugely more efficient, the alternator made that confounded AC (alternating current) sort of electricity, so a rectifier (a converter of AC to DC, good band by the way!) had to be included as well as the regulator.
Early systems had one of each, newer system combined them into a single unit, so depending on the machine, you get what you're given. But the regulator always produces heat, hence its cooling fins, and therefore has to mounted such that the heat can dissipate.
Its not uncommon on modern machines for the alternator to have an in-built rectifier/regulator, so no separate boxes to wire into the loom, sweeter still – until something goes  AWOL.

There are no real restrictions for how far away the battery is from alternator etc (Jag XJS has its battery in the boot).

So bottom line of the charging system is that it generates AC, which in converted to DC, limited (regulated) so it doesn't fry things, and its output then goes to the battery which keeps it topped up, thus keeps everything supplied – or so the theory goes................

Breakdowns/failures
One of the biggest cause of breakdowns is 'electrical', and one of the most frequent reasons is the condition of the wires/connectors, whether the factory fitted snap-together sort just getting old and corroded, home made crimped-on connectors, or switch-gear contacts. (how many of us have pulled a connector apart by holding the wires??)
Modified bikes/cars tend to have the wiring following routes that are new, so tight bends and chaffing should be addressed.
HT leads/caps age and can breakdown.
Water/condensation had the knack of getting where you don't want it, so stuff like WD40 comes into its own.
Old style batteries are lead/acid and need to be maintained.
Newer batteries are 'maintenance free' (phew!)



With luck, that should have either completely confused anyone who read it, or maybe just made it a wee bit more understandable..................  :D

Tend to find having a wiring loom/harness with all the connector blocks relevant to the boxes etc can be beneficial.........  :D (lets them electron wotsits travel about)

With your battery box, it can be a good idea to have a large hole in the bottom of it, as this can help get the battery out if its a snug fit.

If you're going for indicators/flashers, you'll need a flasher unit. (I don't run indicators on mine)

So the red Boyer unit takes the place of the big black Yamaha box marked Ignition Unit? It's currently hanging off the engine by a couple of wires, so presumably can be relocated in the box.

How many terminals on a bike flasher relay?

Some flasher relays have 2 pins, some have 3. I looked at ebay USA under XS650 parts

http://motors.shop.ebay.com/Motorcycle-Parts-/10063/i.html?_trkparms=65%253A12%257C39%253A1%257C72%253A4390&rt=nc&_nkw=xs+650&_dmpt=Motorcycles_Parts_Accessories&_sticky=1&_trksid=p4506.c0.m245&_sop=10&_sc=1

to try and identify parts I wasn't sure of, and that's where the pics of (XS650) the flasher relay came from, and they had 3.



The other widget - not really sure what it is, sorry.
If it's a regulator (ones I saw had the round piece on it as well), its not needed as you have the combined regulator/rectifier (the 8-way plug with 7 wires with big heat sink)

If its a relay for the starter, you still don't need it!

If its something else - ????

The finned thingy has the 8 way connector block & 7 wires you mentioned Tony, so is presumably a later combined rectifier/regulator.

I beleive it is......... :D

So these are the parts I need to fit in my electrics box?

I'd say yes apart from the coil. Prob advisable to keep the HT away from the sensitive electronics of the Boyer and regulator/rectifier.

Guess you could have the box divided so the sensitive stuff is one side and the HT the other, but bear in mind the heat sink of the regulator/rectifier unit has disspate it's heat, and coil needs to be able to stay (relatively) cool too, which is why they're (the coils) are usually, to some degree, out in the open.

Personal view would be to mount the coil where the originals were.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 12, 2012, 09:05:42 PM
The original pair of coils mounted on the bracing tube under the fuel tank, which we've replaced with a length of ERW tube cos it was so damn ugly & sits at an odd angle as standard, (normally hidden by the standard fuel tank). So I don't really want to put it there, but could sling it under the electrics box, along with the reg/rec unit.
Not sure if I've explained it well, but I plan to hang a platform under the seat for the electrics with the "box" simply a pair of covering side panels, (actually welded together at the front edge & held with a couple of Dzus fasteners). So I can make the platform half the depth of the side panels & mount components above & below it, but still hidden by the panels.

Post by: Tony oily bike on November 12, 2012, 11:27:33 PM
Your idea of coil position/mounting should be fine  :) sounds like where it'll be it should be protected from tyre spray too.
Worth double checking the coil you have has removable HT leads cos you're gonna need some long uns .............

Used to use inline HT lead joiners to extend leads. Basically a plastic tube with a brass screw in each end. Screw the old lead in one end & the new length in the other. Job done.

Used to sell loads of those, In the wet they were almost guaranteed to shock but the newer ones seem better waterproofed.
Still with the coils mounted under your arse you'd better be careful how you route the HT leads. :D ;)

Post by: Tony oily bike on November 15, 2012, 11:47:23 AM
They look nice, and fitting non-CV carbs give it an older/classic look too.  Always like the look. ;)

I've a set of roundslide mikunis to fit to mine (quite a common mod), they’re kinda the Japanese equivalent to the mkI Amals

Couldn't quite see if you had insulating blocks between the carb flange and manifold, but just in case you haven’t, I’d suggest it will be worth fitting them as the Triumph workshop manual shows the following assembly order for MkI Amals: carb, O-ring, insulating block, paper gasket, manifold.

One reason for insulating blocks (and in more modern times ‘rubber mounts) is to reduce the heat transfer from the cylinder head to carb,

The original XS650 CV carbs used ‘rubber’ adaptor mounts, and photos I've seen of XS650s with the roundslide mikuni conversion also use rubber mounts.

Really old (early 1900s) vintage bikes can actually boil the fuel in the carb when the bike is parked up after a run........... ask Dslam. We had to wait ages for the darling little bike to cool down!!  ;D

{ 2 } Gonna balance the 2 carbs up using lollipop sticks etc ?
{ 3 } Doing away with the choke slides { if fitted} and fitting blanks ?
{ 4 } Gonna fit the viton tipped needle valves ?
{ 5 } Gonna enjoy have petrol fingers again after a tickling session ?

A quiet afternoon at the workshop today. Various bods there working on their own projects, so I was just tinkering.
Decided to quickly chuck the motor back in the frame to check the carb clearance. Quickly chuck it in -ha!! Big Darren & I struggled with it for over an hour & got absolutely nowhere -except he managed to pinch his big fingers between the engine & frame. Ouch. Could've been worse though. Could've been my fingers.
Even though the engine was in the frame when it was hardtailed, it looks like the bottom frame rails may have tweaked inwards a little during welding. In the end I had to sand the inside faces of the engine mounts with a soft pad on the angle grinder to clearance them. Still took 4 of us to get the motor in. XSs are bloomin' heavy old lumps. Gonna be fun doing it when the frame's painted.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 18, 2012, 07:28:26 PM
The new cast aluminium carb manifolds aren't as sharply angled as the steel ones Pete started making when he built the hardtail. That means I have to fit 1" Amal bellmouths rather than the 3" ones I bought at the Popham Megameet back in August, otherwise they'd foul on the frame. Just as well the 3" ones I bought were the wrong size for the carbs I've got.  :P Anyone want a lovely pair of polished ali 3" bellmouths for 600 series Amal carbs?

haven`t had a chance to look for the cable doowidgey thing yet, had some domestic issues in the past couple of weeks. But i will do it soon I promise.

If my memory serves me well XS650 lumps were always a bugger to get back into the frame. I`ve done a lot of work on them in the past and every single one was a struggle and half to re fit in the frame. I thing it`s because the frame is such a rigid structure compared to other jap frames that flex like spaghetti. I have had to jack the bottom frame rails out (less than 1mm!!!!) to get a lump in, and that was after I stopped the owner from trying to drill the mounts out to get the bolt through!!!!!! Wherever possible I laid the lump on it`s side and lowered the frame over it. Partly because the frame is a bit lighter and easier to handle but also gave us the option of seeing what the frame needed to do to fit. Every one was different, never had two the same and I must have done about 10 of them!!!!! :o :o :o :o


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 24, 2012, 06:54:21 PM
Yup, standard way of fitting a Sportster engine is frame over engine I believe. We tried that too. Can't even strip the motor down then build it up in the frame cos there's not enough room to get the head off.
Nothing worth photographing, but I spent the afternoon yesterday messing about with the rear mudguard & struts.
Just filling in time until the truck door hinge parts arrive from soggy Somerset.

Loony's been having a practice on his Dad's lathe & turned these 10mm thick stainless collars from a length of round bar blagged from Doug of the Guzzlers car club. Loony Senior then milled the slots in them. The threaded mounts weld to the frame & the collars sit over the rear wheel spindle. Undoing the lock nuts & winding the bolts through, pushes the spindle backwards to tension the chain.

I bought a pair of 600 series Amal carbs for the bike over a year ago, then discovered I actually needed the bigger 900 series. So I picked up a pair of empty carb bodies on Ebay. There was some cash in my PayPal account from recent merchandise sales, so I've invested it in all the needles, jets etc I need. Fortunately the guy who sells the cast aluminium carb manifolds on Ebay listed the jet sizes needed to run with the XS motor.
Every piece arrived sealed in it's own individual Amal bag. Even the new throttle slides came in tiny little cardboard boxes. 
On the left are the 3mm thick heat insulating gaskets, recommended by Dslam.

Yeah, I was going to bring them home to do this evening, but the new tickler buttons are on roll pins, with the ends splayed to stop them pulling out of the carb body -so I'd need a hammer & punch to fit them. Less hassle to do at the workshop!

Another late day at the Post Office, (it's beginning to look a lot like Christmas). Trudging the streets in the freezing cold. So not a lot of time at the workshop today. Especially with a visit from Uncle Kev, (Kapri in his gorgeous new motor. See the Fury -ous thread in General Discussion).
Managed to fit the new float bowl priming pins though.
These are supposed to stop fuel seeping out & soaking your fingers when you prime the carbs. Must admit though, I just bought 'em cos they're shiny.
They're spring loaded buttons that push the fuel float down, filling the float bowl prior to starting the engine.

I've got an extended tickler.

I've been messing with this while waiting for parts for my truck project. Now I've got them, (thanks again Doc), I need to put the bike aside -there's a time limit on the truck build so it has to take priority. I'm sure I'l still tinker with this, but the truck comes first.
So this afternoon I de-lugged the bottom yoke, (removed several unwanted mounting lugs), then Chris & I put the front end back in. Just means we can move it around the workshop easier. I'm pleased with it so far. The bracing tube above the engine's slightly out of line with the top of the motor. Think I'll make a tapered fillet of tube to weld under it to fix that.

The tailgate?
The raised bead around the lettering is a swage, rolled into the flat steel sheet for me by a local sheet metal worker. I drew the shape on the sheet in marker pen & he ran it through his former, (2 wheels that run against either side of the metal sheet to form a raised line). Cost me a tenner. Often used to add rigidity to flat panels. You'll usually see it in interior panels of race cars etc. Any decent metalwork shop should be able to do it for you, but you can buy home versions of the tools from places like Frosts Restoration. Or you could make a wooden former & buck & do it by hand.
The "Manky" lettering's actually old fashioned aluminium number plate letters. In the old days kids, the numbers were individually clipped onto a backing plate, not printed on like today's number plates. I found a big box of them at the Dorset Steam Fair a few years back & bought enough to spell Manky for 10p each. I was going to hang them on my shed wall, but they found their way onto the truck instead. The tailgate panel's sunk a little in the middle, so we might have to try & pull it back out flat before it's painted. Should look good when it's finished.

I bought 4 of them for the leather straps on my truck fuel tank, but wasn't sure if I needed the 1 1/2" or 2" ones, so bought 4 of each.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 23, 2012, 07:27:38 PM
Loony's been pushing the bike in & out of the workshop every day to give him room to work on other stuff & was getting fed up with propping it on bits of wood. After hardtailing the original frame, the side stand was too long & the bike threatened to topple over. So today he cut a couple of inches out of it & welded it back together. That's better.
While he was doing that, I cut a slice off the back of the engine side casing. It used to form part of the chain guard, but isn't really needed & I decided it looks better without it. I also gave the casing a quick rub over with some wet n dry paper to take the worst of the gunge off it.
Loony also machined a couple of new mounting lugs for the rear mudguard as the previous set-up ended up sat too close to the tyre. Just dabbling with this from time to time at the moment, while working on my truck.

Not much going on with this at the moment, while I'm working on my truck. Picked up a twin pull throttle cable unit from Ebay last week though. Allegedly from an old Douglas. Being aluminium it should polish up nicely & means I don't need a "splitter" box, (single cable from the bars into 2 cables for the carbs).


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 14, 2013, 10:13:09 PM
Rear mudguard mounts reworked. There's now about an inch of clearance between the trye & the dome nuts under the guard. I had to slot the holes in the guard as the mounting bolts pointed inwards toward each other. So I've just used some large "penny" washers to cover the slots. keeping this build very low tech. Eventually the struts & washers will be chrome plated & the guard painted in Metalflake "root Beer", (a sort of treacly golden brown).

Seat base propped in place. I'll make a tray, suspended below the seat base, to hold the electrical components, hidden by side panels. The front mounting tab for the rear guard will be welded to that.
Once I've fitted the side panels, I'll trim the front end of the guard to the height of the back of the electrical tray.

We plonked the seat on & propped the front mudguard in place to see how it looked. Still need to straighten up the brace tube under the tank, but not looking too bad.

Oh no! It's fallen over!

Fortunately it's landed on those 2 spare car tyres though, which is handy cos it makes fitting the battery box a lot easier. It also meant I could swap the front brake disc for the proper XS650 one I found on Ebay for 10 quid, (the previous one was from some other bike & had different shaped slots around the centre. Now it matches the rear one).
I know it's going to cause me some major hassle at some point in the future, when I'm trying to take the battery out at the side of the road, but I've decided to bolt the battery box in from underneath the frame, rather than from the top. I wanted it to sit down low between the frame rails, partly to give more clearance for the electrics box above, but also just cos I think it looks nicer, with the mountings hidden. So I cut & drilled a couple of flat steel straps & Mr Loon welded them to the underside of the box.
With the bike on it's side, I drilled the frame rails & tapped the holes to M8. So now the box is bolted up in place. Still just playing with this when I get time spare from working on my truck, but now I can see how deep the electrics box can be & sort out the side panels.

Haven't touched this for a while cos I've been concentrating on my truck, but I picked up these new cast aluminium finned carb tops for the Amal carbs the other day -an impulse buy while ordering something on Ebay for a mate.
They got me thinking- they match the finned ali' rocker covers on the Pop. The bike's also got the same ribbed aluminium mudguards, (hand made for me by the same guy who made the Pop ones).
I plan to eventually paint the truck in satin pale green -one of the original factory colours available for '53 Ford Populars, with gloss black chassis & black MMMotors logos on the doors. I'm thinking I'd like to paint the bike to match, with green tank & black frame, (not sure if the 'guards should be black or green yet). I could fit the same green woven spark plug leads too. My green Triumph Speed Triple was affectionately known as Kermit the Thug & I'd like to carry the name on to this build. With the truck already christened Junkyard Frog, they'd make a good matched pair. I could even build a custom trailer to haul the bike behind the truck.

Yeah, there's a guy selling lots of cast covers for XSs on Ebay, but he's not cheap. I bought the Amal carb manifolds from him. They were 115 quid the pair I think, but so much nicer than anything I could've made from steel tube. These were 15 quid each. Not cheap, but I like 'em.

50 quid's worth of 1 1/2" bore exhaust tube, (a couple of straight lengths & some pre formed bends).
Haven't worked on the bike for ages, although it gets wheeled in & out of Loony's workshop most days. It's the local transport festival this weekend though, so I thought I'd knock up the pipes to make it look a bit more like a proper bike.
Started with the left pipe, cutting a 180 degree bend in half & twisting it a little, then tacking it back together. Added a metre of straight pipe. Job done.
I've got some push-in baffles, so will add 2 to each pipe, held with a captive nut & bolt through the back of the pipe.
The right hand pipe will wrap around the frame tube & through the bend of the left pipe, to run above this one. Then they just need a simple hanging bracket at the back & they're ready to chrome.

Right hand pipe made today. It went suprisingly well for a change.
Started with a 135 degree bend at the cylinder head, which I "pie cut" to pull it round tighter, (a series of wedge shaped cuts around the curve, then pulled together to tighten the bend). With that tacked together, I added a 45 degree bend, with just a couple of small cuts in it to open it out a little. Then a long straight tail section. Lots of discussion about slash cutting the ends or cutting the top one shorter to follow the line of the hardtail -if I did that the 2 pipes would end up exactly the same length, which in theory would be best for tuning. In the end I've decided to leave them as they are. Hopefully, with a couple of baffles in each pipe, they should be reasonably quiet.
Waiting for full welding now.

Messing about with the bike again this week, just to have a break from my truck now that it's running.
Not much to show, but a lot of measuring & tacking together of bits of metal. I'm making a box for the electrical gubbins, but don't want it to look too chunky & slab sided. So I've made a tray, suspending under the seat, with mounting tabs for side panels. The various electrical components will bolt onto it, (probably with the regulator/rectifier underneath so it's in the airflow), then I'll make side panels to suit.
Combined with the access hatch in the pan under the seat, I should have good all round accessibility if I need to get to it. I'll cut the side panels deliberately 10mm short on all sides to leave a gap around the edge of them cos I want to keep it looking "light & airy" rather than solid sided.
The front end of the rear mudguard bolts to the base & I've cut it flush with the underside.
Before you ask, yeah I know there's not enough room to get the battery out. The batt' box is open topped so I can charge it or top it up in situ, but it's held by 4 bolts to the underside of the frame, so I can drop it down to ground level to pull the battery out if necessary.

I've been messing about with the side panels for weeks now, between other jobs. Finally got them done today.
I'd spent ages making a folded one piece left hand panel, with a recess for the chain to pass through & was really pleased with it. Unfortunately I'd got the lower fold in the wrong place & the chain would've fouled on it. So I had to cut the bottom edge off, fold a new section & get Mr Loon to weld it on for me.
I've cut the panels deliberately "short" around the edges as I want to show some space around them so it doesn't look like a slab sided box.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 18, 2013, 07:08:55 PM
The left side of the bike's quite "busy" with the drive chain & exhausts, while the right side is relatively empty. It has a full sized side panel. I think I'll cut some sort of recess into it to break up the slabbiness a bit, then reproduce a smaller version of it on the other side. The ignition key will go top right in this panel. Doesn't look like it in these pics because of my wide angle lens, but the bottom of the side panel's level with the top of the battery.

Loon tries the XS for size.
The exhausts are just cable tied in place to see how they'll look. The back end of them will be a little lower to run parallel to the bottom frame rail eventually. You'll need a heatshield on there mate.  ;)
I'm not trying to build a period "bobber", which are all the rage at the moment, but just a simple, rugged, rideable cut down Yam'. Something I can just blat about & have fun on. So I'm trying to keep it as simple as possible. No trick engineering or finicky detailing.

I toyed with the idea of painting it the same pale green & black as my truck's gonna be, but think I'm gonna go with the original plan of "rootbeer" metalflake with a few splashes of chrome & some gold or silver leaf lettering on the tank -"The Coca Cola Kid", (my favourite beverage).

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 20, 2013, 09:00:10 PM
Loony was aghast when he read I wanted bubbles -he imagined 70s custom van style big, multi coloured bubbles. I meant just a very small trail of miniature cream coloured Coke bubbles on the leading edges of a couple of panels -where you might normally use hotrod pinstriping or flames.
Base colour will be metalflake "rootbeer", which is a kind of dark, golden brown, (imagine the colour of a glass of Coke held up to the sunlight). Hoping Loony will handle that for me.
Then I'd like a panel masked off on the top of the tank, around the left side of the filler cap & down the top face of the tank, with that 70s style bubble lettering -kinda like the letters have been inflated to fill the available space -in probably gold leaf, with cream outlining to match the cream bubbles. One for Clive, our resident airbrush expert.
Frame will be gloss black powdercoat.
No rush for paint though. If I manage to get it up & running this year I'll probably do the same as my truck & run it in bare metal till I know everything works O.K, then strip it for paint & chrome later.
Today's jobs- drilled & filed the righthand side panel for the ignition/lights switch. I'm toying with some sort of recessed panel in this, just to break up the "slabiness" of it a bit. This panel's simpler than the left one & is more on show so looks a bit blank. Might be easier just to do something with the paint. Maybe some gold lettering or something?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 20, 2013, 09:09:16 PM
I've been looking online for a universal fitting chainguard. All the custom bike shops used to sell them, but I couldn't find one.
The gentlemen of the workshop can't understand why I want one, but I want to ride this in all weathers & want it as practical as a chop can be. The guard will probably be needed for the MSVA test, but will also keep crud from the chain being flung up -if you've tried washing chain lube off your paint you'll know what a pain it is.
So I nipped down to B & Q today & picked up a metre of lightweight angle for 6 quid. Cut one face off the end of it, & a curved "tail" from some flat sheet, then rolled the other face of the angle around it & handed it to Loon for welding. A bit of trimming up & filing & I had this.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 20, 2013, 09:13:08 PM
It'll bolt into the recess in the lefthand side panel & to a mounting tab on the frame, behind the exhausts. I'll slot the mounting holes so the guard can be slid back & forth when the chain's adjusted. It's almost hidden behind the exhausts, but worth fitting I think. Modelled here by Mr Loon.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 24, 2013, 09:21:31 PM
Mounting stud welded to the frame & slotted holes cut in the chainguard, then bolted to the underside of the side panel & the frame. My only concern is that it might be too close to the sprocket. Depends how chunky the chain is.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 24, 2013, 09:23:31 PM

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 24, 2013, 09:26:32 PM
Exhausts slotted back into place. Just need to finish cleaning up the welds on the right hand pipe & fit the baffles & they're done. They need to be chromed before the engine's run, (the chromers don't like exhaust carbon contaminating their vats).
-yes, there'll be a heatshield!  :)

Decided what to do with the blank looking right hand side panel. I'll ask Mr Clive if he can airbrush a small cartoon character in the bottom left corner of it, (won't be worrying about paint till it's had a bit of a road test, same as my truck).
The bike's gonna be called "The Coca Cola Kid", so I'd like Yosemite Sam from the Bugs Bunny cartoons, but with 2 bottles of Coke in his holsters instead of guns.

Heatshield added. I had one from the balance pipe of a Harley in my spares box. It would normally mount with Jubilee clips through tabs on the back, but that looked poo. So we welded a couple of 6mm nuts into the pipe & it bolts to those. 10mm spacers tacked to the back of the shield raise it off the pipe to allow cooling airflow underneath. Hopefully it's enough to keep my leg clear of both pipes.
I bought a bunch of push-in exhaust baffles a while ago. We ended up welding 2 together to form a 12" long baffle for each pipe, held with a single 6mm bolt at the back. I grew out of overly loud pipes years ago & think a nicely set up, smooth running machine's more impressive than something that pops & bangs & won't tickover. I may also keep this bike outside the house I lodge in to commute to work on in the Summer, so noisy pipes wouldn't be appreciated. I'm hoping these custom pipes will sound more or less like the original bike. Of course, it might turn out to be over baffled & restricted, in which case I'll just pull the baffles out & cut a bit off the end of them.
A bit of smoothing around the front curves & these are ready for chroming.

Looking really nice Andy , make sure your baffles  are secure I done a trackday on Saturday and on the third session my bike spat the baffle out of the silencer, maybe a spring washer would be an idea, loving the exhausts tho looks good now so should look awesome chromed.

Finished cleaning them up today.
Mr Baychimp's found a place in Alton, Hampshire, (local to us), who do chroming. He's getting his exhausts done in the next week or so -he bought my trike project from me. A couple of guys here have offered to do them, but as he's putting his in fairly soon, I'll bung mine in with his.

Bob, (Baychimp), & I visited a local chrome this morning & dropped our respective exhaust systems off. Mine are made from a mixture of mild steel & stainless steel sections. They said the 2 metals react differently to chroming, so there may be some difference in the colour when they're plated. That's fine -this will be just a daily rider, not a show bike. They also said they can't guarantee the chrome will reach into every nook & cranny of Bob's Reliant manifold. The copper & nickel coats should, but the top chrome coat may not. Again, he's happy with that.
About 150 quid per system, but they're snowed under with work, so it'll be 8 to 10 weeks before they're done, which means I won't be riding the XS to the "Trip Out" show in September as I'd half planned to.
Some before snaps.

This evening I went & bugged my brother Steve at his workshop over in Wiltshire. He's a proper craftsman & I do try not to bother him with my bodged together bits & pieces, but I needed some fuel tap mounts TIG welded into my tank. I bought a pair of 1/8" NPT taps from the States for 10 quid each, then some threaded inserts. Steve blanked off the Harley fuel tap mount under the tank, then TIG'd the new mounts into the holes I'd drilled.
Thanks big bro.  :)

If you fancy some bespoke fabrication, he's the very chap to see, but be warned, top quality work doesn't come cheap & he doesn't suffer fools -unless they're related to him.

Rear light mount. I've been messing about with a couple of off-cuts of tube & came up with this, to mount the reproduction 1940s Chevy rear light to the offside of the frame. I plan to eventually put this bike through the MSVA registration test as the frame's been cut in half, so it should be re-registered. Very few chop builders seem to bother doing that though, so I may end up running it on the original logbook to begin with, just to get it on the road.
The test requires lights to be centrally or symmetrically mounted, so if I fit one on the right side of the frame, it should have a matching one on the left. I've got the original Yamaha light though, which is the size of a house brick. I'll fit that temporarily to keep the testers happy.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 06, 2013, 10:45:12 PM
The Chevy light will fit here, level with the exhausts on the other side of the frame. The frame will be powder coated gloss black, so the light housing & the bracket will be black too.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 08, 2013, 08:26:05 PM
Rear light fitted, though I need to slot the mounting holes as it's drooped very slightly. The lens is about 3" diameter, so it's actually quite a sensible sized light. The wires will run inside the frame tube.

Next job is to rework the Suzuki footpeg mounts, using the original Yamaha pegs. They need to be a couple of inches higher to be comfortable with the gearchange pedal & also to give better clearance for cornering. Once they're done I can sort out the brake pedal.

Decided the rear mudguard was a tad too long as I want to hang the numberplate underneath it. I've already drilled all the mounting holes though. So while I was out & about today, I took it back to Darren at Brooklands Bodycraft near Oxford. He very kindly shortened it by 2 inches & reshaped the end, adding the wired & beaded edge, all for a princely 10 quid.

Been a while since I worked on the bike. Other projects getting in the way.
Had a couple of hours to myself in the workshop this evening though, so I cleaned up the rear numberplate mount I began a while ago. Bashed out of a flat sheet of steel & rolled & bent, then bashed some more, until it fitted under the mudguard. I had to cut it in a couple of places to follow the shape I was after, so Mr Loon then welded the gaps up & I cleaned the welds back. 


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on September 21, 2013, 07:53:01 PM
Bolted in place under the guard. I hate side mount numberplates. I've had them on several of my old bikes, but never been happy with them. So I'm using a 5" x 7" plate, curved to the profile of the tyre.

I'm going to re-register the bike, but found a place on Ebay selling flexible Perspex plates, for trials bikes, & wanted to see how much they'd bend. They were only 6 quid, so I had one made with the original bike reg on it. They're normal hard Perspex, so are reflective, but have enough give in them to curve around the tyre. I'll add a yellow plastic numberplate screw in each corner to keep it in place, (taped in place for now). I have a small LED light that'll tuck up under the lip of the guard to illuminate the plate.

Plate size should actually be 7" x 9". The digits are the correct size, but the spacing between them is less than it should be & the overall size is 2" smaller each way than standard. I've run this sized plate on most of my bikes in the past though & never had a problem. A lot of sports bike riders use 4" x 6", which is literally the size of a postcard & unreadable from more than 10 feet away.

Hi Andy, maybe I've missed something  ::), but why are you re-registering?
Thought you still have:
The original headstock/front frame section section and hence VIN as per log book.
Original engine number as per log book.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on September 22, 2013, 11:42:03 AM
And a frame that's been cut in half.
Yamaha, (or any other high volume manufacturer), is granted a licence to build bikes, based on a sample batch of vehicles submitted to VOSA for testing. They guarantee their quality control will ensure every bike will be the same & meet the same test standards. In return, they get a licence to build, say, 10,000 bikes. All the same.
Some muppet in a shed hacks the frame in half & builds his own back end from whatever he's got laying around, chrome moly, ERW, cheese, whatever. However good he may think he is, it's not the same vehicle any more. It hasn't been tested & may well be lethal, not just to him but to every other road user. It's supposed to be tested & given a new identity.
If you build a hotrod you can use an old chassis & can add extra outriggers or strengthening, but can't remove anything, to stop you compromising it's structural integrity. Same with a bike. Older British bikes had 2 part frames that bolt together in the middle, so you can mix & match front & back ends. All modern bikes are one piece. Cut it in half, it should be re-registered.
There's a million hardtailed bikes out there though & no-one seems to bother with re-registration. Presumably the relevant authorities just aren't as clued up as the car guys. Things are changing though & the whole system's gradually tightening up. Having put my truck through the test & now starting a roadster build that'll also be properly tested, I know it ain't as hard to pass as some think & I'd rather get it right now, than have an MOT refused somewhere down the line & a letter telling me to submit it for testing.


Title: Re: Manky's XS650 Yamaha
Post by: Tony oily bike on September 22, 2013, 12:35:26 PM
OK, can see some logic. Have no issue in road going vehicles being "fit for purpose" (so long as its not by the cheese-builder).

If the bike is examined (and passes), does it therefore loose it identity as a Yamaha (as per the four wheeled Manky Wagon?) and require a new frame number along with a new registration number?

Will reg number be a Q plate?

Not yet, but I will. No gaskets where the pipes push into the cyclinder head yet, cos the engine may well need looking at before it's run. So the pipes aren't clamped up tight to the head. I need them on the bike to make sure nothing fouls on them though -got footpegs, clutch cable, maybe altered chainguard etc to do yet.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on September 28, 2013, 06:48:39 PM
Messing with the footpegs again. Suzuki mounts, welded to sections of the original XS pegs. The ends need cutting off & turning through 45 degrees so that they fold in the right direction. I've got brand new rubbers to replace the worn out ones.
They sit a couple of inches above the bottom frame rail, which will help with ground clearance, but feels a little odd at the moment cos I've been used to just wedging my feet onto the frame. Perfectly comfortable though.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on September 28, 2013, 06:50:56 PM

Haven't touched this for several months, while I've been driving my hotrod about, but some time ago I gave my brother, Brock, a spare pair of engine casings & asked him to TIG weld up the Yamaha lettering. He gave me the first one back as a Christmas present. Nicely done. The other to follow soon, (it's my birthday in 2 months so maybe I'll have the set by then!) I plan to nickel plate these cos although he's done a top notch job, the lettering's still visible from certain angles as it's a different colour. I've got a spare set of tappet covers for the top of the motor so will have them plated too.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 23, 2014, 08:22:45 PM
Standard XS650 seat height's around 30", (different saddles on different models, but somewhere around there).
Haven't actually measured the new seat height on mine, but it's about the same as most of my trikes, so about 20".
I've kept the original engine cradle, (frame tubes around the engine), so ground clearance below the motor should be more or less standard -whatever that is. 4 or 5 " maybe?


Title: Re: Manky's XS650 Yamaha
Post by: kapri on January 23, 2014, 10:08:11 PM
It was primarily the frame clearance I was interested in Andy. 10" drop on the seat ,that's pretty low ! Mine is 30" as stock and I was looking at about 4-6" drop as it needs to be comfortable as well as cool looking.

Called at my brother, Mr Brock's Wiltshire workshop on Wednesday. He handed me the other engine side casing while I was there. He's TIG welded up the "Yamaha" lettering in the circular alternator cover. This is a spare casing -it's only the circular cover that he was working on. A small area that kept bubbling, due to impurities in the casting, but otherwise it's come up well. I'll gently run a flat file over both casings to smooth out the ripples, then wet n dry them & buff them as best I can. I plan to get them nickel plated to hide the slight difference in colour between the weld & original metal.
Thank you Steve.  ;)

A lighter attached to a tank full of petrol?!
I was thinking the petrol would keep the Coke cold so actually not a bad idea -apart from it being shaken up as you ride along & probably exploding in your face!

A beautiful morning down here in Hampshire for a change today -let's hope it bodes well for the Summer. So Mr Loon & I dragged the XSs, kicking & screaming, out into the sunshine. Loony bought my spare XS engine from me last year, (I'd arrived with it in the boot of my car & he bought it before I'd even unloaded it), but he's building this one for his mate Tom. The deal is Tom buys the parts & Loon has a free hand to do what he likes with it. Yes, the knobbly front tyre will be changed!

Tom's.

The alternator casing that my brother Mr Brock TIG welded for me, (he's removed the Yamaha lettering). Waiting for him to repair the other exhaust pipe at the moment -I had them chromed, but had ground the heatshield mount down too far, to make sure the exhaust collar would fit over it, & the threaded insert pulled out of the pipe when I tightened it up. Hopefully Brock can TIG a new one in without too much damage, (it'll be hidden under the shield).

I've got to alter the frame brace under the fuel tank, by raising the front end, so it sits horizontally, (I know it looks right in this shot, but it's not). I'd also love a tad more rake, but that would mean putting the frame back in a jig & cutting away most of the headstock bracing, so it's unlikely to happen. Quite pleased with it so far though. I haven't had a bike for a few years, so I'm looking forward to blatting around on this.

the bike can be raked without even removing the engine as the identical slugs will line up everything

Haven't posted anything here for a while, but the XS is still very much on the go.
Best Christmas pressie this year was this voucher from my big brother Mr Brock. After being made redundant last year he's finally gone into business as a welder/fabricator, building everything from tractor mudguards to drag cars. I couldn't normally afford his rates but you get what you pay for & he's definitely one of the best. He's rushing to get his own race car ready for the coming season at the moment, so I won't be redeeming this just yet, but will spend a day at his Wiltshire workshop as soon as he's free, re-raking the headstock & as many other jobs as we can do. Thanks bro  ;)

Post by: Manky Monkey on January 01, 2015, 08:26:52 PM
I've had a change of mind on the colour since I last posted too -much cheaper to do before the paint's bought. Instead of golden brown with the name "The Coca Cola Kid", I'm going with the same pale green as my truck & "Junkyard Frog", (the title I wanted for the truck but it'd clash with all the Manky logos).
I've been saying for a long time now that these will be my last builds cos I just want to get out & enjoy what I've got. So I think it'll be cool to have a matched pair, truck & bike, (yes, I have thought about building a custom bike trailer to tow behind the Pop). So black frame with pale green tank & side panels. Both vehicles use the same handmade ribbed ali' mudguards so the bike ones will be black to match the truck's. The bike carbs have limited edition finned ali' tops, similar to the rocker covers on the Pop engine & I'll use the same green cloth braided HT leads. I've also just picked up some green plastic fuel pipe which I'll use on both vehicles.
Instead of painting the name on the tank I plan to have it engraved on the engine casings & they're already in Spain, awaiting the attention of a very talented metal artist called Tony Reynolds.
So nothing new to show, but things are slowly moving forward.
Something like this.

I've been on Tony the engraver's waiting list for a while, but looks like my engine casings have reached the top of the To Do pile.
Tony's an English old school biker who lives in Spain with his wife & churns out some gorgeous work at a phenomenal rate. All done with nothing more than a hammer & chisel.
My brother, Mr Brock, TIG welded up the Yamaha lettering on the aluminium cases for me, but the alternator cover had a lot of impurities in it, so didn't weld too well. Tony's got a mate in Yorkshire though, who machined up a batch of thicker replacement covers. So this is my lefthand casing with a new circular alternator cover, hand engraved by Tony.

Post by: Manky Monkey on February 27, 2015, 09:05:45 PM
Wow indeed.
As Mr Olds pointed out on FaceBook, it rather raises the stakes for the rest of the bike build now doesn't it.
I ain't rich & this work's costing more than I paid for the original donor bike, but I really don't intend building anything else, (apart from a joint project with Loony at some point), so I figure I'll do it right & have something I can enjoy for years to come, (I hope). Tony really is a craftsman in the old style & I'm pretty sure he'll become as well known as Don Blocksidge for example, who's been the name in gunsmith & bike engraving for 40 years at least. So I'm looking on this as buying an artist's work before he becomes super famous.
The man himself.

 ;D We've been trading messages for a while now. Crazy guy but crazy good.
First part finished. He rubs black paint into the low spots then polishes the high spots to achieve this effect.
I've basically told him I want the frog on both sides of the engine, facing forwards, & the words Junkyard Frog on the right side, (not enough room for "Greener than a" but it doesn't really need it), then to go crazy with the rest & do whatever he thinks appropriate, but keep it frog or junkyard related. So I'm expecting lillypad or bullrush styled filigree or loads of tiny spanners or frog footprints, something like that. We'll have to wait & see. Just PayPal'd him a large wadge of cash to cover the first half of it. Super stoked about the results so far.

:) He lives in Spain with his punk wife, but he's got a mate in Yorkshire who's a machinist. They were both going to a bike show in Germany, so I sent my cases to Yorkshire, then his mate took them to Germany & passed them onto Tony, who took them home to Spain. My bike's still only half built so I've told him to just fit me in around other jobs. No desperate rush & it'll give me time to save up the rest of the cash.

Yeah, that was just a mock-up on tracing paper. We both think the name should only be on one side of the engine, but he'd thought on the left & I'd assumed on the right. Can't go on the left though cos it'll be partly hidden by the exhaust. The righthand case is bigger & is easier to see when the bike's parked up on it's side stand.
So same lettering but on the other side.

Tony's an ex tattooist, so cleans the cases up, blows them over with a light coat of matt white paint, then draws the design on tattoo transfer paper before laying it onto the case.

Ahh, of course. Obvious.

Lillypad leaves don't look very exciting apparently & not easily identifiable as being frog related, so we're going with the more traditional filigree work.
Bit of a problem with the welded up lettering. Early Japanese engine casings are notoriously poor quality & full of impurities which bubble to the surface during welding. I've had XS650 & 750 covers welded before & had the same trouble each time, so no reflection on Brock's welding. Tony's probably not too pleased about it, but says he can usually hide blemishes in the background. Hopefully it works out O.K

As long as the pinholes are in the background, if it came to it, he could add a dab of filler cos it'd be hidden by the black paint he uses on the low areas, (these holes are just in the surface of the metal, not all the way through). Worst case scenario, the holes are in the raised areas & he has to get them re-welded locally, (& it costs me a lot more money), but technically, he shouldn't need to cut into the raised areas -so, we'll wait & see.
Tony had exactly the same problem with an XS650 casing for his own bike, to be called The Gentleman, which is why I sent him my spare set of covers.

Can't afford to ever get any more done, so if I ever sold the bike, I'd find a spare set of casings & keep these. Artwork for the wall if nothing else.
We'd talked of getting really wacky with it -"funked up filigree" as he put it. I gave him a free hand to do whatever he fancied, but in the end, it's pretty traditional. I'm certainly not complaining though. I love it.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on March 12, 2015, 08:44:55 PM
Another full day spent on it. Tone's well & truly knackered now.
The pin holes in the welded up areas have messed with his funked up filigree plans, so he can't cut as deep into the centre of this panel as he'd like. Still pretty damn cool as far as I'm concerned.
You can see dark areas around some of the "Junkyard" lettering here. I'm assuming that's Chemical Metal, or whatever the Spanish equivalent is, in the holes & won't show once the background's blacked.


Title: Re: Manky's XS650 Yamaha

I agree Bobbi -apart from the being glad it's not cheap bit.  :D
I'd planned the bike as a very simple hardtail for blatting about on, on sunny days. Just hope the engraving doesn't seriously out-shine the rest of it now.
Tony's finished the righthand cover, but can't engrave the oil filter housing, (the small circular bit on the right), cos the face is only 1mm thick. Chatted with him by FaceBook message earlier & his mate the machinist in Yorkshire's going to turn a new one on his lathe with a domed face, so Tony can do his thing on it. That's another 60 quid.

He told me he's actually got one that shape in his shed so I told him to do whatever felt right to him. Glad I did.

Single frog footprint on one of the tappet covers -a tappet dancing frog?
XS650s have 3 triangular tappet covers on the top of the engine & one square one. The very first models had a de-compression lever to help starting & the valve lifter was fitted to the square cover. I asked Tony to add something Froggy to the odd one.

reckon it could make an interesting brake pedal as it has a bit of a curve to it and could look like the foot pad was held in the jaws of the spanner.

Whatever works for you mate.
Yeah, I was thinking a rod clamped in the jaws for the gearchange, but might work better as a brake pedal. Not overly keen on themed bikes or ratrods covered in spanners for door handles, link rods made from welded up chain etc, but I've never seen these swan neck spanners before & I've got one engraved on the engine now.
I might have a bid on that. It would make interesting workshop wall art if nothing else.

Thanks to Big Darren & his van, the bike's now at my big brother, Mr Brock's fabrication workshop in deepest Wiltshire. He foolishly offered to do a day's work on it for free as my Christmas present -so I took it, & all the parts I had for it, over to him, listed all the jobs that need doing & said keep it as long as you like & do as much as you want.

Brock begins to realise it may have been the worst present idea ever.   


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on March 27, 2015, 08:52:28 PM
First job is to add a little more rake into the front end. The fork tubes are pushed up through the yokes by about an inch & a half at the moment. So push them back down to where they should be, which will raise the front of the bike, then probably cut a wedge out of the top tube under the tank & heat the top of the front down tubes. Pushing down on the top of the frame will then lower the front & push the forks out, further forward. Maybe.


Title: Re: Manky's XS650 Yamaha
Post by: hunter on March 27, 2015, 10:44:02 PM
I think the stance looks great.
If it was mine i would shorten the forks.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on March 28, 2015, 03:46:32 PM
Like most hardtails, it's a few inches longer than the original frame. So standard length forks make it look a bit "flat nosed". Needs the front kicked out a little to bring it back into proportion. The bottom frame rails sit an inch & a half higher at the front than the back, so adding a bit more rake to the front end should drop it down level to the ground & give about 4 & a half inches of ground clearance.

Post by: Manky Monkey on March 31, 2015, 07:46:45 PM
Despite managing to seriously hurt my back, (typical -right at the start of my week off), I drove, very painfully, over to Steve's workshop this morning. Just confirming I was happy with what he'd done really, then we stripped the bike down to a bare frame so he could fully weld it.
He sent me these photos yesterday. He's raked the headstock. Barely noticable but he took a 30mm slice out of the top tube, heated the top of the down tubes & gently eased the front end out. The bottom frame rails now sit parallel to the ground. It's enough to look "right".


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on March 31, 2015, 07:50:01 PM

Post by: Manky Monkey on April 04, 2015, 10:17:38 AM
Lots of tidying up to do on the frame, (not Brock's work, which is super tidy), so I need to spend an afternoon with the MIG welder or body filler, depending on whether I go with paint or powder-coat. All the mounting tabs are in place now though & it just needs a couple of fixing holes drilled in the electric box base.
Steve spent a huge amount of effort on the footpegs, which were completely different from one side to the other. They're a mix of Suzuki frame mounts & Yamaha pegs & now sit level & true to each other & fold as they should, with newly machined capped bungs in the frame mounts.
He's fitted the torque arm for the rear brake caliper, though as he pointed out, it's in compression when it should be under tension.
Re-worked the top engine mount to remove the brace tube that normally runs under the tank.
Made & fitted a very tidy brake pedal/master cylinder set-up, which involves a rod turning inside a tube across the frame, with brass bushes in either end, with the modified yam' arm pushing up into the cylinder, with a nice little return spring bracket.
Re-worked the left side panel to lift the chain guard clear of the chain.
Modified the front headstock gusset I'd made.
Fitted the headlight.
Fitted the front mudguard.
Made & fitted a bracket to hold the mini speedo down on the left fork leg.
Oh, & cut, raked & braced the headstock. It now has 35 degrees of rake. As far as I can ascertain from the 'net, standard rake is 27 degrees.

I'm really happy with it & very grateful to big brother, who hasn't charged me a penny for his time -yes, I'll find a way to pay him back.

Big thanks to Big Darren for transporting the bike back from Brock's place in Wiltshire to the lock-up garage that Loony & I share in Hampshire this afternoon.
I need to strip it down now, take it to the workshop & spend a couple of afternoons filling low spots, cleaning up old welds, working out where the electrical components will go & drilling holes for wiring, then it's ready for shot blasting & powder coating.
And of course, huge thanks to my big bro for his time & talents. Thanks mate.  ;)

Took the top cover off my engine this afternoon to get at the 2 top engine mount studs, which are seized into the ali casing & have just been hacksawed off at either end by a previous owner. Managed to snap the chrome oil feed pipe that runs up the front of the engine in the process. Poo. There's a guy in Germany selling brand new ones on Ebay, but they're 70 quid each.
On a brighter note, Tony the engraver's finished the main cases. The small round cover inset in this case holds an oil filter. Although it sits quite deep into the main case, the front is only 1mm thick -too thin for Tony to work with. So his mate in Yorkshire machined up a new cover with a domed front & he's added the frog's head on it. I'm really, really pleased with these & so is he, which is good. I've Paypal'd him the last of the cash for them, which is apparently paying for a new roof on his workshop in Spain. Just need to sort out the postage now. Somehow I've got to clean the rest of the motor up to be worthy of these.

Found a way of paying my brother back.
I bought another XS engine from a bike breakers in Stoke on Trent. I picked it up for spares for my own, but most of the bits I wanted aren't actually on it -so I've given it to Steve. He hasn't got a bike licence but always had an interest in bikes & had asked me to look out for a cheap engine. There ya go -do something interesting with that.
Drove up to Stoke today, collected it & delivered it to Steve's workshop in Wiltshire.
I've swapped the aluminium handled dipstick for my plastic one, taken the top engine mount & Steve's going to take off the chrome oil feed pipe that I broke on my own. It's also fitted with the early model decompression valve lifter, (to make starting easier). Slight damage to the cable clamp which can probably be repaired. I'm very tempted to fit it on mine, just because I've never seen one fitted before so it's an interesting detail. Need to check that it will fit a later engine though -plus I've just paid a small fortune to have that tappet cover from my engine engraved! Maybe I could fit the engraved one on the Pop somewhere  :)
So a very expensive dipstick, (no, not me), but nice to do something for my big bro for a change.

Spent the morning at a local vintage Japanese motorcycle autojumble & picked up a few XS650 parts.
Found a Haynes manual, a set of points & backplate, a brake pedal pivot & the phone number for a lefthand engine casing for Brock;
A pair of front brake calipers & mounting brackets for Tom, which I bartered for his spare alternator for Brock:
A headsteady bracket & an oil feed pipe for my own:
A righthand engine casing, phone number for the lefthand one, dipstick & front engine mount for Lunatic.
-handy that we all have the same model of bike  :)
I also picked up this little tank for a fiver. Early 100cc Suzuki maybe. Plus a brand new Honda chrome fuel cap to fit it, still in it's bag for 6 quid. Picked it up cos I knew Loony would like it & sure enough he's grabbed it for his XS. Propped in place on Tom's.

Displayed my unfinished XS on our pitch at the Basingstoke Transport Festival yesterday, minus the engraved engine casings cos they were still in Spain.
They arrived this morning. Amazing workmanship & as Loon said, great to be able to handle them after just seeing the photos Tony the engraver posted on FaceBook. Nowhere safe to put them for now, so they're tucked away in my bedroom! Really, really pleased with these.

Still quietly sorting out bits on this while working on my truck every afternoon.
I had a leather stirrup strap left over from the truck, so took it to a local saddlery shop who shortened it down & stitched a loop in each end to form a strap over the top of the battery. My truck has the same over the top of the fuel tank. I'm trying to build them as a matched pair, with as many shared features as possible.
After the saddlery shop, I collected a pile of parts from the powder-coaters. These were just easily unboltable bits that could be done in gloss black while the bike's just sitting in the garage, including both mudguards & their mounts, the rear light, number plate bracket, rear brake anchor arm etc. Unfortunately they had a problem with the mudguards, which kept reacting & wrinkling the finish. Not really a problem as they can be flatted back & spray painted.
I need to spend some time going through the bike, marking all the wiring holes that need drilling & any other modifications, then I can strip it down, smooth the frame out & get it off to the coaters.

Not sure if I've mentioned it before in this thread, but now I'm in my 50s, I've decided I don't want to spend the rest of my life building things -I want to get out & enjoy the vehicles I've got. So my truck & my bike are my last, but they're the keepers.
I've had half a dozen XSs over the years. Lots of other bikes in between, but I keep coming back to them. They're the level of biking I'm comfortable with. Fast enough to be fun without being stupidly fast, basic enough to be fixable, stylish enough to be cool. I'm hoping this one will be a good, rideable mile muncher. If it makes me grin it's doing it's job  :)
Hope to have the frame powder coated & the tank painted in time for the Popham show, but it won't be finished. Not far off though.

So. With just a week or so till the Popham Megameet bike show & with the Yam' all in one piece in bare metal in the garage, it's time to pull it all apart, paint it, then panic about getting it back together in time.  :P
I've got a couple of wiring holes to drill & a mounting tab to make for the rear brake reservoir, but otherwise, it's just a case of cleaning up some scruffy welds around the back of the engine cradle & sorting through the pile of bike parts I've taken off to decide what needs powder coating. The frame, yokes & any small parts will all be gloss black. Hopefully I can aerosol spray the tank in green before next weekend too.
Had a minor panic when I suddenly realised the battery box is missing. I remembered taking it to the coaters about a month ago, but not actually collecting it. A quick call to them confirmed it's still sitting there waiting. So I'll pick that up when I drop the frame off on Monday. It'll be tight, but they reckon they can have everything coated by Thursday night.
While that's being done, I've been collecting some of the service parts I need -new headstock bearings, fork seals, front & rear wheel bearings, clutch cable, sprockets etc. I'll clean up & fit as many as I can while it's apart, but it's just going together again for the show. I'm not planning on having it road worthy till the Spring now. I've rented a van to take Tom's XS & mine to the show next weekend.

You're right Mr S, doesn't matter if it's not finished, but I'll get it as bike-like as I can. I was going to spend a couple of hours pulling the forks apart to fit new seals, then realised it won't look any different, so it can wait. Not planning on getting it on the road till the Spring, so this is just a visual exercise for now.
Got the frame back from the powder-coaters this afternoon. 120 quid for the frame & a big box of all the small parts from Tom's & my bikes, shotblasted & coated in gloss black. Done in 2 days. It's an industrial quality finish, but fine for our needs. They shotblast in the same workshop they coat in, (but obviously in a walk-in cabinet), so there's sometimes pinheads of grit trapped under the coating. I've spotted a couple on the top seat rails, but they'll be almost hidden by the saddle & the engine engraving will hopefully distract people's gaze from them anyway!
We built the hardtail from ERW tubing -"steampipe". It comes from the suppliers with a screw-on collar on the end of each length, presumably to join them together. So we welded 4 of them into the axle plates, just to add a bit of detail & to make the frame look a little more industrial. They don't have any function at all, but the coaters have very carefully masked the threads before coating, so I'll have to paint them back in by hand.  :)

Many thanks to Big Darren, (& his neighbour who was unwary enough to wander over for a chat while we were there), for lifting the engine back in with me this afternoon. No swearing at all, which has to be a first.
I'm going to run the motor as it is & see how it goes, rather than stripping it right down to inspect it when it may well be fine. So now it's in, I'll scrub the ali' casings up in situ. Only spotted one hole I've forgotten to drill so far, which is better than I expected. The coil mount. Of course, it'll be a bugger to get to now.
Back to Loony's workshop later to clean the wheels & forks up.

Swearing -I've rented a van for the weekend. I hate the logistics of ferrying non running projects about for these shows. Always costs a fortune in rented transport, always last minute hassles. I enjoy the shows once I'm there, but getting there's a nightmare.
I've got an American made "Western Eagle" saddle on the bike. Cost a fortune but it's a lovely low profile, sculpted shape. Bought it 3 or 4 years ago & it's been moved from one place to another without a scratch. Loaded the bike frame & boxes of parts in the van this afternoon to move it all across town to Loony's workshop. First time I dabbed the brakes the frame tipped over in the van & the headstock sliced a neat semi circle through the vinyl seat covering. Poo. That'll be another 50 quid to get it recovered then.  >:( Not sure if Phil the upholsterer can stretch vinyl that tight, but hopefully he can do something with it. He's got all Winter till I need it on the road, (though I'm still wondering if we can get it to the Dutch show in November somehow). Ideally I'd have it done in tuck n roll vinyl to match the seats in my Pop.
I was at Loon's workshop till midnight last night, fitting new bearings to the wheels & bottom yoke & will be heading over there again later to paint the mag wheels & spray the tank.

Thursday the 19th of November. We catch the overnight ferry from Harwich to Rotterdam.
Been at the workshop this evening, putting the bike together for the Popham Megameet bike show tomorrow. Not running, just mocked up, but I'm quite pleased with it. Looks totally different with the frame coated. Built it up in the back of the hire van I'm sharing with Tom & his XS. I'll fit the tank in the morning, but maybe leave the engraved engine casings off until we get there!


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 17, 2015, 10:50:06 PM
Just as well I decided to fit the engine casings before we left -had to take one of the exhaust pipes off to get the left one on.
A very busy day on Sunday, starting at the workshop at 7am, fitting the tank, cases & a few odds & ends, before Tom arrived at 8 to load his XS in the van. Then we were off at a very sedate pace, listening for the clatter of bikes falling over in the back, to Popham airfield. Only 6 miles away, so we were there in plenty of time for the 9.0.clock meet up with Terry T & his Portsmouth Trike Club guys.
We parked the bikes on his pitch, but ended up pushing them across the field later to display them on a stall specialising in XS650 parts. The stall owner said they really pulled the punters in & he could've sold mine 15 times over. I was curious to know what people thought it was worth & every time we came back past, the theoretical asking price had crept up a bit more. 2 1/2 grand by the end of the day, which is about what it's cost me, (1 1/2 for the donor bike & parts, plus a grand's worth of engraving). Bizarrely, there was another bike at the show with engraving by the same guy, (he lives in Spain).
I blew the petrol tank over in the same green I painted my truck, just in aerosol paint, scrubbed to a satin finish with a Scotchbrite pad. Suprising what a difference a bit of colour makes. It suddenly looks like a proper bike.
Tom & I agreed, it really boosts your enthusiasm to show the bikes & get some feedback from other bikers. Seemed to go down well.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 17, 2015, 10:54:16 PM
I really like it without the mudguards. Think I might shorten the rear one a little & curve the mounting struts. Also wondering if the side panels should be green or black?
The bike's now safely stowed in the lock-up garage again. Need to crack on with my truck, ready for the Dutch hotrod show in November. I'd really like to take the bike too, to display alongside it, so can see me renting a van yet again. Looking forward to riding this now.

Well I'm in the other camp - while the side panels would look good in green, I think they would draw attention away from the casings, and the nearside one would also have the exhaust cutting across the shape of it.

Tim Horton's, the chain of coffee shops in Canada & the States, sell boxes of donut nibbles, supposedly the bits from the middle of their ring donuts.  :D
if anyone's still interested in the bike, rather than holey Jaffa Cakes, (sounds like a line from Batman & Robin), it's tucked away in the garage for the time being while I concentrate on my truck, but after a little bit of welding, I'll probably get the side panels powder-coated in black. If I don't like them I can spray them green over the top.
I'm going to try & shorten the rear guard a bit & reshape the support struts to make it less obtrusive cos I really like the look of the bike without them, but need to keep it reasonably road legal.

A parcel arrived by courier at 7.o.clock yesterday evening. A new saddle to replace the one I damaged a few weeks ago. It's A "Western Eagle" solo seat from the States, the same as before, but they don't seem to make the one I had any more. This one's slightly smaller & not as curvy, but is in "tuck n roll", pleated vinyl, which will match the seats in my truck.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 02, 2015, 10:05:59 PM
I really liked the previous saddle, so asked Phil the upholsterer to try & repair the tear in it. He did a good job, but I just wasn't happy with it, so decided to replace it. This one sits a little higher, so I might end up fitting shorter springs. It's fine, but will take some getting used to after the ultra low one I had before.
Archie's bought the old one from me for his budget chop project.

Right hand side casing's been off to re-fit the oil pump, (I dismantled it when the casings were sent away for engraving). Also replaced the oil strainer & refitted the cover with a new gasket. Everything looks fine in the bottom end so I'm not going to pull it apart if it doesn't need it.
I've fitted the twin lead coil under the seat -not the original XS one, but it was on the bike when I bought it. I used a pair of inline suppressors to join the original HT lead to the new cloth braided ones & fitted new caps & plugs. The vintage style cloth covered HT lead is the same as used on my truck, (green with a red fleck). I had 2 offcuts of it left over & they turned out to be almost exactly the right length.

Post by: Manky Monkey on October 12, 2015, 07:43:32 PM
Rear light's back together & on, though I managed to scrape the black powder-coat in the process. I've touched it back in with black paint, which will hopefully polish out & not show. It's a reproduction vintage Chevy truck light. Mr Olds kindly extended the wires for me as I haven't got a soldering iron -they run inside the frame tube to the battery box under the seat. It's supposed to earth through the body, but as everything's powder-coated now, I'm not sure it will. May have to run a separate earth, or scrape off some coating when it comes to wiring it up.
At some point while my brother was raking the headstock or Pete was hardtailing the back end, the upright tube behind the engine's moved about 5mm. Not a huge problem, everything's still nice & true, but it means the rear engine mounting plates don't fit. So I spent this afternoon cutting a new pair. Once I know they fit I'll get them coated.
The saddle's growing on me now I've got it properly fitted, but can't really try it out till I've got the front end back in.

A bit more tinkering today. If my truck's not ready for the Dutch hotrod show in November, this'll be Plan B. I'll rent a van & take the bike to display instead. So it needs to at least look like a complete bike, rather than a box of bits propped together in the exhibition hall.
Every job I start seems to involve having to drive across town to Loony's workshop to pick up a tool, or drive across town in the other direction to buy nuts & bolts etc. Slow progress, but getting there.
I decided to shorten the rear mudguard as much as I could cos I really like the look of the bike with no guards at all, but don't want the hassle of being pulled over for not having them. Ended up slicing 3" off it -any more & the number plate would be horizontal & unreadable. I cut it from the front end, so that I kept the rear mounting holes & wired rear edge on the guard. It's made of aluminium, (hand made by a guy in Oxford, who made the similar guards on my truck). The powder-coaters can coat ali', but have to warm it in the oven, then spray a light coat of powder on to it, so that it partially melts, then a heavier coat over the top. Normally works, but this time it ended up wrinkling & sagging. So I've rubbed it back with 180 & 400 grit wet n dry & Mr Loon will spray it in 2 pack gloss black.

Post by: Manky Monkey on October 14, 2015, 06:50:30 PM
I was going to replace the guard support with curved rods, but quite like it as it is. It matches the front one. Sits more upright than it used to though, because I've shortened the guard, so now it will foul the brake caliper. I can cut a section out of the front hoop though & replace it with an S bend.


Title: Re: Manky's XS650 Yamaha

The engine mounting plates fitted with a little adjustment, so now I'm making the top ones. The original Yam' head steady's an immensely complicated affair, made of 6 pieces that bolt together. Without it, the engine shakes a fair bit though, so I'll make a much simpler 2 piece version. I've cut the bottom sections from 3mm angle & just need to make the top bit, then weld them together.

I know I've asked this before, but need to check again -the bike came with aftermarket electronic ignition, which replaces the points. There's a pick-up mounted where the points used to be & it's got a slightly more modern twin lead coil.
I've also got this little red box of tricks. It all worked when I bought the bike, but there were all sorts of dodgy connections & wires not doing anything, so I ripped the lot out & just kept the components. I also had a box of spare parts though, so now I'm not sure what I need & what I don't.

I've got the original Yamaha CDI unit, but not sure if I need that too? (I'm a Postie, not a vehicle electrician). It has a finned casing to help it cool & happens to have exactly the same bolt pattern as the fusebox in my 'leccy box, so I've bolted the 2 together for now, with the CDI hanging in the airflow under the box.
Not needed? The red Boyer unit doesn't have any mounts on it, but I could attach it to the underside of the box lid or the inside of a side panel with Velcro, with a multi pin plug for the wiring.
So I've got wires from the points/pick-up unit & from the alternator & from the coil -what connects to what?

Why not just contact Boyer Bransden, send them the pic, and ask them?

They do instruction sheets spo you only need to know which unit you have and you can get all the gen!

Now you tell me! Bought a square of black self adhesive Velcro from Ebay last night.  :(
Nothing to show today, but lots of measuring up, buying bolts etc, then sorting a few small jobs out for the bike at Loony's workshop. After spending so long working on my truck, it's nice to work on something different for a few days.

The guys at Boyer have been very helpful to me in the past when I had problems with a Lucas system and was seeking a Boyer replacement for an XS650, so much so that they told me how to fix the system I had (it all related to in-series coils, which I replaced with a single 12V dual output Dynacoil)

The good thing with your Boyer is that the unit will still operate if the battery voltage drops a little, where as a Lucas system can simply stop operating.

Its quite common for the original (40 yr old) XS650 coils to breakdown when they get hot (from the engine), stopping the sparks. Once they've cooled, they get going again. With your newer dual-output coil you'll hopefully avoid this, though it could be worth checking the coils impedance is matched to the Boyer box of tricks.

Thanks Tony. It seemed to work when I bought the bike but I couldn't ride it cos it had no chain or brakes! -still hasn't. Like the rest of the engine, I think I'll hook it all up & see what happens, rather than tearing it apart if I don't need to.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 16, 2015, 08:32:09 PM
Working in a rented lock-up garage across town from Loony's workshop means constantly traipsing back & forth for even the simplest of jobs. I go to fit something, find the bolt's too long or short, have to go across town, which can take half an hour of sitting in traffic sometimes, 2 minutes in the workshop, then back again. Or I have to go & buy a couple of bolts or a clip or whatever -another hour gone.
So getting there slowly, but everything's taking far longer than it should. No front end on the bike at the moment, but at some point soon I need to turn it around to work on the other side.

A couple of bits made up in Loon's workshop this evening. I'll have to wait till tomorrow to see if they fit.
Modified side panel, (one of the mounting holes didn't line up properly). The notch in it's for the chain. When the bike was at my brother's workshop we cut the notch out & raised it to give more clearance for the chainguard.
Headsteady brackets cut & welded together. Tom, (one of the regulars at Loon's workshop), bought his from a company in the States. Lazer cut & very nice, but 50 quid a pair. Mine cost me a fiver for a length of angle iron from B & Q.
Rear mudguard mount, modified to clear the rear brake caliper, I hope.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 17, 2015, 06:50:50 PM
Everything seems to fit, which is nice.
I'm quite enjoying taking a short break from the truck to tinker with this. Mainly nuts & bolts stuff & far simpler than a full car build.
Rear mudguard strut clears the brake caliper -trimming 3" off the guard meant the strut moved forward so I had to cut & re-weld it. Not sure how it'll work out when I adjust the chain though -I may add a spring loaded tensioner sprocket under the chain at a later date. The rear strut now follows the back edge of the caliper mount & the front one follows the edge of the caliper itself, so hopefully it looks like I meant it that way.  :)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 17, 2015, 06:55:28 PM
Headsteady brackets also fit. When I bought the bike the head bolts were sheared off in the ali' casting. My brother bored them out for me, but they need a small file running through them to clearance the bolts.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 17, 2015, 06:59:25 PM
Side panel fits now too. After the discussion here I decided to go with black instead of green, but the left one needed the chainguard recess modifying, so I've rubbed the powder-coat back to key it for paint. I've notched the front edges of both panels for the HT leads to pass through, with a rubber grommet around them.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 17, 2015, 07:03:05 PM
Lifting the chainguard to give more clearance over the rear sprocket meant the mounting hole didn't line up with the stud welded on the frame any more, (I'd slotted the hole to allow for chain adjustment). The guard's made from another length of B & Q angle iron.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 17, 2015, 07:07:31 PM
So I welded up the slot & added a new mounting tab. Again, no allowance for moving the rear wheel to tension the chain, but I'll see how it works out before over thinking it any more. Back to the garage in the morning to see if it fits.
So now I've got a boxful of bits to be painted & powder-coated gloss black. Looking forward to rolling it outside to get a good look at it.

Post by: Tony oily bike on October 17, 2015, 07:08:45 PM
Looks neat 'n' sweet Andy, really coming along.

Not sure where/how your coil is mounted (somewhere behind the panel I'm guessing), but suggest it has a degree of free-air flow around it to stop it getting too warm, esp as it looks like the zorst is right close to the side panel  ;)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 17, 2015, 07:20:31 PM
The coil's bolted to a tab welded to the back of the frame toob behind the motor, (about 3" from the zorst). I've deliberately cut the side panels to give a gap around the edges, partly for extra air flow & partly so the 'leccy box doesn't look too solid & slab sided.

I'm definitely a fair weather rider these days -I've done my time riding in the rain & snow. Now I'll just ride for fun on sunny days. So the bike won't see the tarmac till the Spring, but I'm putting it together at the moment to take to the Dutch hotrod show in November. I've got the rest of the Winter to finish it & get it MOT'd, insured & taxed.

Don't think I've ever been that cold but I'll never forget trundling round the M25 on my way to a rally one March day on the GT which of course has no fairing.  I was supposed to be meeting someone at Clacket Lane service area, saw the sign and the junction was coming up and had a few moments of panic when I realised my clutch hand wasn't working!

So, to re-cap, I'm renting a van & taking the bike to a Dutch hotrod/bike show in 2 weeks time. I'm on holiday from now till then, so spending this week fitting as many parts to the bike as I can, then working on my truck next week, to try & get it ready for some paint before the Winter.
The bike won't be running for the show, but doesn't need to be. I just don't want to take it as a pile of mocked together parts.
It came so-o-o close to disaster this afternoon -I'm working in a rented lock-up garage with no power supply so by 4.30 it's too dark to see what I'm doing. It's been sat on a single axle stand with no front end for a while, but this afternoon I'd got the forks on & was trying to get the front wheel in before the light went. I was knelt in front of it, lifting the forks a little to wrestle the wheel under the front guard by myself & didn't notice the rest of the bike slowly tilting on the axle stand until it passed the point of balance & suddenly fell to one side. Arrgghh!
Somehow I managed to throw myself under it & stop it hitting the deck, but with the front wheel half in & half out, I couldn't straighten the front end or lift the bike back onto the axle stand or lift it upright. I was stuck there in the gloom, unable to move. Fortunately, after 5 or 10 agonising minutes, wondering what the hell I was gonna do, a neighbour drove into the garage area & I was able to yell to him to give me a hand. XS engines are bloomin' heavy, but thankfully I'm O.K, thanks for asking. I'll never dance the Mongolian clog dance again though -which may be a blessing.
So, lots of little jobs done recently, but nothing very photo worthy. Now it's back on it's wheels though, I can roll it outside for a bit of a looking at. The engine's virtually untouched, apart from some pretty side cases, & needs a damn good scrub with wet n dry, wire wool & chrome cleaner to brighten it up, but otherwise not too bad so far.

Glad the bikes OK (and you  ;).)

These lifts are about £60 delivered (which is a tad more expensive than timber). The cups are width & height adjustable to suit most machines, and if wanted, you can remove the slidy extensions and simply use it as a flat height adjustable platform (with some suitable anti-slip matting in place).

500 kg rated so could be of use on a car too.

Our favourite auction site has them...............

Never owned a lift, but I've made several paddock stands over the years. Hopefully no more lifting to do on this one, but I might have a look at those Tony.

It's always the stoopid stuff that ends up hurting you.
No more near misses today. Put a couple of bits on, took a couple back off again.
With the headlight brackets & the light itself now powder coated black, I decided the bars needed to be black too. So off they came & over to the coaters this afternoon. Should be ready by the end of the week, which should give me time to clean up & paint the front master cylinder.
I put the rear mudguard on. The coaters have had real trouble with these aluminium guards. The powder keeps reacting with them & giving a very orange peely finish. They look fine in photos, but have an odd, leathery look to them. Wondering if I should just take 'em off again now, rub them down & spray them. Might do tomorrow.
I've bonded a length of plastic washer pipe to the underside of the rear one & run the wires for the numberplate light through it.

I had a bad day today.
Spent a fortune, taking out AA membership, plus a supplement for European travel for the Dutch trip next week, plus travel health insurance & picking up a wadge of Euros for the trip. An expensive morning, but hopefully everything's sorted now.
So back to the bike-
Fitted the headlight unit into the powder-coated shell. It's a Bates style light. I've had loads over the years & never had a problem with them. Put the lens into the shell, slipped the retaining ring over it & did up the securing bolt. Walked away, came back 5 minutes later & knelt next to it to work on the engine when ..bang! the glass cracked in about 4 places. Bugger. I'd obviously over tightened the screw & put it under tension.
Fortunately, through the power of mobile phones & the internet, within 2 minutes I'd bought a replacement from Cycle Haven in Lincolnshire, but that's another 30 or 40 quid I didn't plan on spending. Mr Loon's Triumph Speed Triple's in the same lock-up & has mis-matched Bates headlights, one normal & one halogen, so I've actually pinched the normal one with the old style curved glass & will replace it with the new flat glass halogen one when it arrives -yes, I did ask him first.
Took the left hand engine casing off to replace the clutch mechanism that I removed when the casing went to the engraver & discovered the clutch pushrod that actually moves the clutch plates is missing. Good job I didn't plan to ride the bike to Holland. I bought the donor bike as a running non rider, (it had no brakes or chain -& still hasn't), so I assume it's always been missing. So this evening's job is to find another one on the 'net.
Decided the mudguards really do need respraying, so took them off again & over to Mr Loon's workshop.
Every job seems to involve at least one nut or bolt that I need to go & buy or one hole that needs filing out. I think I'm actually going backwards at the moment, taking off more parts than I'm putting on. One week till it needs to be on the ferry to Holland -what could possibly go wrong!  :P

Agree with you there stinky. Most show goers tend to gawk at the pretty or outrageous vehicles rather than the ones with real effort in them. Though I believe the Dutch crowd are a bit more clued up than the average American or Brit.

I know, I know. It's got most of the main components already, so I'm adding as many smaller parts as I can in the next few days.
One step forward-
replacement halogen headlamp lens arrived this morning, (ordered yesterday afternoon -ain't Royal Mail brilliant). Fitted to Loon's Speed Triple & his mis-matched older style one fitted to my chop.
Fitted a few bits & pieces -brake pedal, kickstart, top engine mounts etc, then had a visit from Mr Melosman, all the way from Yorkshire to buy my spare V8 motor. Nice to meet you Marc & thanks to Big Darren for helping to lift it into his car.  ;)

The powder coaters rang to say the handlebars were ready, so Loon & I nipped over this afternoon & collected them, (they'd also coated a wheel rim for a bike he's building for our mate Tom).

One step back-
pulled the front caliper apart to fit a new piston & seals & managed to shear the old bleed nipple off. Bugger. An hour of messing about with drills, welders & taps couldn't save it. So I've pinched one of Tom's & will replace it -another Ebay shopping trip this evening.

Are they like the Righteous Brothers?

Step forward-
the shortened speedo cable arrived this morning. Fits nicely but the bends are a little tighter than I'd like. If the inner cable snaps in use I'll just have to fit one of Speedy Cables' 90 degree drive units to the wheel.
Fitted the black powder-coated handle bars. The ends were masked off to make sure the switchgear & grips still fit. Hopefully I've measured them correctly. The brake & clutch lever mounts need a quick coat of black to tidy them up before I fit them. I also had the throttle unit coated. It's a twin cable one, possibly from a Douglas Dragonfly.
Fitted a new front sprocket.
Removed the engine sump plate to replace the oil filter & sump plug. Still quite gungy under the motor so needs a bit of a clean up before next week.
Fitted the last of the engine mounting plates, (had to re-make the triangular ones at the back of the engine because the upright frame tube must've moved slightly when the frame was chopped & the bolt holes didn't line up. The bolts will only fit from one direction, so I had to take all the other engine bolts back out & turn them around so they matched -yes, it does matter.
Sorted out various small jobs that need to be done at Mr Loon's workshop.

Step back-
Fitted the ignition switch in the righthand side panel & found it fouls on the coil, (I made the panels & my brother made the coil mount later). Only an hour or so's work to weld a piece of steel in the mounting hole & cut a new one 2 inches further back, but then it'll need re powder-coating. No time before Holland, but hopefully the panel will fit as it is for now. If not I'll just leave the switch out for the show.
Got to spend some time at Loony's place tomorrow sorting out the front caliper & lots of other little jobs. Pleased with it all so far though.

First off, I don't normally go for this style of bike but I have to say I really like this.
I am accused of spending too much time on form and asthetics but what most don't get is that function and form go hand in hand.
If it looks right etc etc.............
I cannot find fault at all. It flows nicely.
Nice bike.
Now finish it and enjoy it ::)

It's always at this point that I start thinking they look better without the tank fitted & wonder about a long thin "rocket" style tank. Hardtails look quite drag bikey without the fuel tank -maybe that's why you like it?! 


Title: Re: Manky's XS650 Yamaha
Post by: Dslam on November 15, 2015, 09:00:05 AM

It's got a few marks on it -"striations" from the press when it was made. So in the next 3 days I need to add a tiny skim of filler down the sides & spray it again, (just aerosol paint). Busy, busy.

Decided to leave it as it is in green aerosol paint for now. Mr Loon's painting the mudguards & handlebar lever mounts for me tomorrow.
Lots of small jobs finished today.
Continuing my policy of buying everything twice, I bought an expensive Goodridge hydraulic brake light switch for the back brake. Then when I went to buy another for the front, found another make for a fraction of the cost, so bought a matching pair of the cheaper ones. These take the place of the normal banjo bolt in the brake line.

Post by: Manky Monkey on November 16, 2015, 11:26:19 PM
I've also bought a crankcase breather from a later model of XS because it's half the size of the old one so much neater. This came from a guy called "The Tired Kraut" in Germany who sells XS parts on Ebay. They always arrive polished & supplied with new gaskets & bolts -& he throws in a little packet of sweets with every order.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 16, 2015, 11:30:15 PM
The tappet covers were filthy & pretty scratched up, so I've made a start on scrubbing them clean.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 16, 2015, 11:34:11 PM
The clutch pushrod was missing from the engine so I've ordered another from Ebay. Also need to fit a blanking plug in place of the starter motor as I'm going kickstart only. Both parts live under the lefthand casing, but I needed to put it back on so I could replace the exhaust. So all this will have to come off again at some point.
Chain guard & left side panel also fitted, both powder-coated gloss black.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 16, 2015, 11:37:25 PM
Can't fit the right side panel until I've refitted the rear mudguard, but I've sorted out all the gubbins inside the electrics box. The red unit at the top is the Boyer electronic ignition. Then the fusebox, black billet rear brake reservoir & the grey bit's the twin lead coil. Need to find someone to wire it all together over the Winter.


Title: Re: Manky's XS650 Yamaha

Front brake caliper scrubbed clean & rebuilt. This is another Ebay buy after someone at Loony's workshop who wasn't me snapped the bleed nipple off in the old one & we couldn't get it out.  :) New black coated Goodridge brake hose fitted but I can't add the fitting at the other end of it until the handlebar controls are on.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 16, 2015, 11:45:25 PM
Various shiney bits on the engine, but the crankcases & barrels still need a good scrub. That'll have to wait till after the Dutch trip now.

You're actually not the first to ask Steve.  :) (still got a scruffy & rain soaked V8 here for you by the way).
No paint Mr S -my experience of painted engines is that it always discolours & flakes after a while, so I'd rather leave it in bare ali' & just scrub it with wire wool or chrome cleaner once in a while.
Already got a blanking plug for the starter moter Arch', but I'm curious about the reservoir -got a link?

Raining here this morning, so I busied myself cleaning up the tappet covers before re-fitting them, as well as the tank.
Loony braved a bad back to go to the workshop & spray the mudguards & lever mounts for me this afternoon, so I can fit them tomorrow.
And that's about it -add the mudguards & handlebar controls, bolt on the other side panel & cut the front brake hose to length, (that's what's coiled up on the handlebars at the moment). I'm thinking of fitting indicators too, so I've got a new switch unit coming & am browsing for small LED lights.
Got to remove the exhausts & lefthand engine cover at some point to fit a clutch pushrod & starter blanking plug, then it just needs a chain & wiring.
Nothing clever, just a basic, rideable chop -which is what I set out to do. Looking forward to riding it in the Spring.  :)

Found the Smedspeed page.

http://www.smedspeed.co.uk/startconv.html

Basically, they use the end caps from the starter motor & weld in an ali' centre section to turn it into an oil tank, taking your old motor in exchange. I gave mine away, (can't remember who to now), but think I'll stick with the blanking plug.

No photos again but the bike's loaded in the back of a rented van, ready to head off in a couple of hours.
Brake hose fitted & new indicator/horn/light switch that arrived in the Post this morning fitted.
I had to take the van back to the Peugeot rental place because there's a gouge on the bulkhead that wasn't on the damage sheet. Loony & I had already loaded the bike by then. The sales guy said Nah, don't worry about that, we're only interested in outside damage -but tell me about the motorcycle.  :)

A great weekend away with good friends. The bike seemed to go down very well & got lots of attention, though the lack of manufacturer's name on it seemed to confuse some show goers.
The exhibition hall's great, but has very dark walls & floors & lousy lighting, making photography a nightmare. I didn't bother taking my camera this year because last year's shots were so fuzzy, but took a few on my phone.

I'm considering adding indicators to the bike. It's a 1980 model, so doesn't need them by law, (required from '86 onwards), but at some point I'm going to put it through the MSVA test to re-register it, so it'll need flashers. Plus it's no consolation to know you don't need 'em when you're laying in the gutter cos some idiot's knocked you off because he doesn't know what hand signals are. It's just self preservation for riding in modern traffic.
I've been perusing Ebay for some suitably tidy LED units -small & unobtrusive but bright & easy to spot. I've already got a new handlebar switch with indicator function. Found these & was intrigued so I ordered a set before I left for the trip to Holland. A set of 4, from Malaysia, with free postage ..£1.98  For that price they were worth buying just to have a look at.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 25, 2015, 11:04:10 AM
Yeah, they've got a hole through the middle. Unusual. I could use the front ones as cable guides & the exhaust could exit through the rear ones!


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 25, 2015, 06:38:15 PM
The stems are in 2 parts, but I can't see how they fix together. If I can shorten them, these won't look too bad.
I know trad' bikers hate indicators, but it's got to be rideable & I'd like to stay alive a little longer, so I'll definitely fit some. I'll run the front brake hose through the righthand one, just because I can.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 25, 2015, 06:43:39 PM
The lenses have a slight green tint, which will fit in with the colour scheme. I assume I'll need resistors to make them flash at the right speed, (LEDs usually flash too fast on 12 volt bikes, so an inline resistor cures that). Anyone know how many pins I need on the flasher relay? I'll Velcro it to the side of the electric box, so will it need a separate Earth connection?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 25, 2015, 06:47:18 PM
European style yellow tinted headlamp lenses are popular with the kids building "brat style" bobbers at the moment. While I was at the car show in Holland I found a stall selling yellow bulb conversions for a couple of Euros. A glass sleeve that fits over the bulb. I was curious to see what it would look like. Might use it, might not, (are yellow lights legal in Britain?)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 25, 2015, 06:51:36 PM
Also picked up a pair of self adhesive rubber knee pads, shaped to suit Sportster petrol tanks.
Does it look better plain, or do they break up the blankness of the tank & give it a slightly more vintage British look? I don't want to over accessorise it, but can't decide.


Title: Re: Manky's XS650 Yamaha
Post by: BikerGran on November 25, 2015, 08:31:14 PM
I think it kind of 'integrates' the tank withy the rest of the bike.  On the other hand, it looks fine without, just a matter of your preference I reckon.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 25, 2015, 08:48:28 PM
Yeah, I was thinking the same -that's not a very flattering angle either, (makes the forks look really stumpy). The tank's got a couple of small dings in it, so I'll fill & re-spray it before making up my mind.


Title: Re: Manky's XS650 Yamaha
Post by: Tony oily bike on November 25, 2015, 09:06:57 PM
Reckon it could be a good idea you have someone take a photo of you sitting on the bike with your feet on the pegs so you'll see where your knees are in relation to the rubbers, that way you'll get an idea if they "fit" the bike or not.  ;)

Post by: scannerzer on November 25, 2015, 10:03:57 PM

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 26, 2015, 08:48:05 AM
Holey flashers Batman.
The frame's been hard tailed -cut in half & a whole new back end added, plus the headstock's been raked. It's no longer the way it left the Yamaha factory. So it should be re-registered. If you remove sections of a car chassis it should be tested again through the BIVA test.
They're starting to crack down on cars now, but bikes have gotten away with it for years. I'll run it on the old log book for the first season, to fix any teething problems, but at some point I'll register it properly.


Title: Re: Manky's XS650 Yamaha
Post by: the coppersmith on November 26, 2015, 09:27:09 AM
You are quite right Andy, as a converter of kit cars and the odd hot rod. DVLA and its associates are planning a big crackdown, not just on the stuff in general, but I've been informed by a well informed source, nudge nudge, wink wink, that they are hitting a lot of Q plate stuff, seems you buy a kit and use the plate and vin, who would do that ! ::) but also the pre 60 brigade are being watched, buy an old chassis and build a MOT exempt wotsit.
                As for your bike, very good, would love to build a copy. In my eyes you have the dimensions spot on. As for the tank rubbers? I'm nt to sure. I can see where you are coming from with them, pity you couldn't make them slip off. Indicators? why not. Love the doughnuts.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 26, 2015, 09:48:59 AM
Yeah, if I don't use the tank rubbers I'm sure someone else in the local workshop collective will. The idea was to keep the tank plain because the name's on the engine cases. Knowing when to stop adding bits is important -less is more.
Still jobs to do on it. Got to take the exhaust back off so I can remove the lefthand cover & fit the clutch pushrod that's just arrived in the Post, as well as the starter motor blanking plug. I've just ordered a rebuild kit for the front brake master cylinder cos it's seized. Got to move the ignition switch, make indicator mounts, remove the mudguards again for cutting back & polishing -still lots of little jobs to do.
There's a multi thousand pound car featured in Custom Car magazine this month that's just been pulled for incorrect paperwork. Now it's got to be BIVA'd. With MOT stations & insurers linked to the DVLA database, it's getting much easier to find the dodgy ones. When I was in Holland at the weekend there was a lot of talk about how easy we have it here compared to the rest of Europe.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 27, 2015, 05:51:42 PM
More or less decided against the knee pads, but might be persuaded at a later date.
Exhaust system back off again & engine casing removed to fit the new clutch pushrod. While I was at it, I also fitted the starter motor blanking plug I bought from Hugh's Handbuilt in the States, (what did we ever do without the internet? -well, you wouldn't be reading this for a start).
That big hole's where the starter motor usually fits & connects to the idler gears on the inside of the cover.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 27, 2015, 05:55:57 PM
The blanking plug is in 2 halves that clamp either side of the casing, (yeah, I know it's out of focus but I'm not taking it back off to re-photograph it). With a new oil seal fitted first, it was a perfect fit. Now the engine's kickstart only I don't need the idler gears, so left them out when I replaced the cover, with a new gasket.

And from the outside it looks like this.

A techy question for you:
The + battery lead usually connects to the starter solenoid, but I haven't got one cos I haven't got a starter any more. So it connects to the alternator & ignition switch, via fuses? If so, what size cable do I need from the battery & how do I hook it up to both the alternator & switch? What sort of connector will take a battery cable going in & 2 wires coming out?

The splines on the gear selector shaft that the pedal fits onto are badly worn, almost flat. I've added a small grub screw to try & hold the pedal tight on the shaft, but it's not ideal. So the sensible option would be to replace the shaft assembly while the side cases are off. It's not cheap, (about 80 quid for a new one), but if I'm keeping the bike long term it makes sense to do it. Never fitted one before but I've got a feeling it's not straight forward -the engine has to be in a certain gear before taking the old one out. I'll research it a little & see if I can afford it.

Do you have a seperate rectifier and regulator or combined ?
Three leads from alternator to rectifier. 30 amp (2.5mm) lead with 20 amp fuse from rectifier to battery.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 28, 2015, 11:20:10 AM
It's got Boyer electronic ignition, so no regulator/rectifier. Doesn't the power also need to go from the battery, through the ignition switch? I'm only asking from curiosity & to try & get the components in the right places in the box- I'll be looking for someone else to wire it up for me.

Yep as coppersmith said rectifier has nothing to do with ignition,
It controls the amount of charge the battery gets.


Title: Re: Manky's XS650 Yamaha
Post by: morrag on November 28, 2015, 10:24:32 PM
No, a rectifier converts AC to DC, the regulator controls the amount of current the battery, a DC item, of course, receives, which is why both are required to charge your battery. However, should you not require a battery supply, for lighting etc, then it is possible to dispence with Rectifier/Reg. units, provided you have a kick start, plus a directly generated supply from your alternator to whatever solid state ignition system you are using, Morrag


Title: Re: Manky's XS650 Yamaha
Post by: Olds on November 28, 2015, 10:34:45 PM
Yep. Unless you also have the optional extra Boyer Powerbox then you wil need the original rec/reg.
The alternator produces as the name suggests an alternating current that needs to be modified to a DC current.
No indicators on this simplified diagram and starter motor is shown but you can just ignore these leads.

Need to get some longer bolts tomorrow, but the reg/rec unit can go back where it was, slung under the electrics box, in the airflow & mounted off the same bolts as the fusebox.
Side panel invisibly mended -previous ignition switch hole welded up & new one cut because the back of the switch fouled on the contents of the box. Needs re powder-coating now, but I've got some indicator brackets to make so they can be done at the same time.

Not much to show, but lots of little jobs getting sorted. I've just taken delivery of a new gearshift shaft & oil seal from YamBits, so now I need to remove the clutch from the righthand side of the engine, as the gear selector mechanism's behind it.
Bought a pair of new carb inlets with domed mesh filters on them as well as little things like a new stainless steel side-stand spring & a flasher relay specifically for LED indicators. Nathan, (Galaxie 500), has replaced the red horn button in the new handlebar switch with a black one for me & is also going to wire the bike, as a paying customer of his new business, Bright Light Customs   
http://www.brightlight-customs.co.uk/

I've made mounting tabs for the indicators from 2mm steel & took them & the side panel to the coaters this afternoon. Hopefully they'll be quite unobtrusive, but bright enough to be seen.

Grey, drizzly & miserable weather here. Not the time to be working in an unheated lock-up garage on a motorcycle.
Lots of small jobs getting done, but nothing really worth showing.
The new gear selector shaft's arrived from YamBits -over 80 quid, but it'll properly fix the problem of worn splines on the present one, (the gear lever won't grip the shaft so slips around it as you try to engage gears). Now waiting for a clutch holding tool cos the clutch assembly needs to be removed to fit the shaft.
Need to cut a few stainless bolts down to the right length & order a few more for various parts.
Bought a nice shiny braided Earth strap for the battery but it was too short, so ordered another, but the suppliers sent one that's too long. Silly little jobs, but they seem to drag on for weeks.
New carb air filters, bug catchers.

Starting work early every day at the moment & not finishing till gone 4 in the afternoon, (I'm a Postie & the Christmas rush is in full swing for us now). Too wet & dark to work on my truck, so I'm trying to do a little bit each day on the bike. Working by the light of the torch app' on my phone though is a bit of a pain.
Couldn't figure out why the front brake master cylinder was seized -couldn't move the lever at all. After faffing about for a few days I ended up buying a rebuild kit for it. Turned out to be the wrong kit but I was able to make one good set-up from the old & new parts. Refitted it on the bars & the lever was locked solid again. Some investigation, with a bigger torch, found the lever to be fouling the throttle unit -nothing wrong with it at all. So I rebuilt it for nothing, but it's 35 years old so probably due for an overhaul anyway.
Switchgear & levers fitted to the bars but altering the layout a little on both sides means there's a small area of the original chrome showing. So the bars will have to come off again for re coating. This time I'll get them completely coated in black & rub back the ends to fit grips etc if necessary.
Need to buy a chain soon -any idea who stocks overlength chain to suit an XS650 & the best way to measure it?
No real progress at the moment, but slowly plodding on.


Title: Re: Manky's XS650 Yamaha
Post by: Olds on December 09, 2015, 08:35:34 PM
Think the chain onthe XS is a 530. (5/8" pitch).
What I do is measure the distance between sprockets. Times this by 2 then divide by 0.625  then add on half the number of teeth of each sprocket. This should give you the chain length in links.
I tend to buy slightly long then shorten to suit and it's always worthwhile getting a cranked link and some spare joining links.
You could try 'The Chain Man' he gets around the shows and I think his details are on the web.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 09, 2015, 08:47:28 PM

Title: Re: Manky's XS650 Yamaha
Post by: Olds on December 09, 2015, 09:13:17 PM
Looking at your bike I would guess at about 116  link but that is just a guess.
If you know how much stretch you have over a std bike, you can just add the extra length times two, then divide by .625 and add that to the std chain length


Title: Re: Manky's XS650 Yamaha
Post by: Tony oily bike on December 10, 2015, 08:17:51 AM
Another chain length measuring option - Borrow some-one else's chain (old, used & abused is fine), and count the 'gaps' on the rear sprocket.  ;)

There's a chain seller (looks like husband and wife) in the room under the grandstand at Kempton.
Dslam and I have bought many chains from them as they do a large variety of spec, and prices are very good. Usually get a slight over-length and a couple of split links just to be on the safe (belt 'n' braces) side.

Next Kempton is Sat 23rd Jan

Lousy phone photos, but I rolled the bike out in the rain this afternoon to look at the indicators I fitted in the dark last night. Reasonably inconspicuous. I've routed the front brake hose through the right hand one, just because it amused me.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 11, 2015, 05:50:04 PM
The wiring for the rear ones runs very close to the wheel, but I found a pair of black rubber, 90 degree battery terminal covers, which fitted the back of the lights perfectly & help to route the wires out of harm's way.

New German made black finished switch unit is CNC machined aluminium & contains horn, high/low beam & indicator switches. As you can see, I had the middle of the bars powder-coated black, but changed my mind on the layout of levers & switches so a small area of the original chrome now shows. I'll get the bars re-coated completely black.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 11, 2015, 05:55:38 PM
I've had to turn the Douglas Dragonfly throttle unit through 90 degrees to stop the brake lever fouling on it. So the throttle cables now lay over the top of the lever, rather than hanging under it, which actually looks tidier, (less dangly cables).

Soggy bike -see, I'm a ruffty tuffty biker who takes his bike out in the rain.
Need to take the right hand engine casing off this weekend & tackle the gear change mechanism -the splines the gear lever attaches to are badly worn, so it slips around the shaft when you try to engage the gears. I've bought a replacement shaft, but need to take out the clutch to get to it. Not a job I'm looking forward to. Side panel now re powder-coated & fitted with the ignition switch in it's new position, (to clear the contents of the electrics box behind it). Battery Earth lead also fitted.

When I arrived at Loony's workshop 6 or 7 years ago, I brought all my tools & we added them to his collection. Now he's moving workshops, we need to have a conversation at some point about who owns what. I've got a socket set, given to me by my parents on my 17th birthday, & a couple of hand tools in the garage at the moment, with nowhere to keep them together. So I blew my Royal Mail Christmas bonus this week on a new tool cabinet -the joy of being a single guy. I can spend my money on important stuff  :)

 ;D That's good, outside the box thinking. Wouldn't have occured to me, but I like my wide bars, so will just get them re-coated, (got some truck parts to take there soon anyway).
So. It's 27" between sprocket centres & roughly 32" between the outside edges of them. Front's about 3 1/2" diameter to the tips of the teeth & the rear's about 7 1/4". What does that tell you -apart from I'm rubbish at maths?


Title: Re: Manky's XS650 Yamaha
Post by: Olds on December 12, 2015, 08:46:04 PM
Tells me that you didn't read the instructions  ;D ;D ;D.
I know you have a 17t front sprocket. Assuming you have a std 34t rear.
17/2 =8.5   
34/2 =17
(27 x 2)/0.625 =86 .4
8.5 + 17 + 86.4 = 111.9

Think you need a min 112 link chain. Not as long as I thought.




Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 12, 2015, 09:47:04 PM
That's witchcraft that is.
Yup, standard sprockets front & back.
So I'm looking for maybe 115 links, (I'd rather take a couple off than be 1 short), of 530 chain?


Title: Re: Manky's XS650 Yamaha
Post by: Olds on December 13, 2015, 08:06:15 AM
Chains will normally be an even number (including the joining link). I would suggest a 116 if you can get it (not that I doubt your measurements). We used to sell 120 as a standard, cut to length chain to those who were unsure as that would fit almost anything.
Seeing as adjustment may be limited, I recomend getting a cranked link. You may not need it but it gives the option of an odd number of links.
Do you have a link breaker ? If not, I will dig out mine.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 13, 2015, 10:51:53 AM
 ;D I was going to ask if I could borrow yours , (never doubted you'd have one). I used to have several, but haven't needed one for a decade or more, so they're lost in the toolbox of time somewhere.
Explain the cranked link to me please.


Title: Re: Manky's XS650 Yamaha
Post by: Olds on December 13, 2015, 11:39:33 AM
Links are made up of consecutively two tubes spaced by two plates (inner)and two pins between two plates(outer). A joining link is a pin type that is removable and has to fit to tube type links. If the length you require does not have tube type links at both ends, a cranked link replaces the last links on the end to make it so.
Used to be very common on rigid bikes and is very handy when adjustment is limited.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 13, 2015, 11:51:20 AM
Ahh. Never used one. I guess I always managed to adjust it out to the nearest 2 tube links.

 :) Many thanks to Mr Olds for lending me his chain splitter today. I'll double check my measurements tomorrow then order the chain.
Took the righthand casing off today & removed the clutch, ready to take out the gearshift shaft. I'm very wary of just pulling it apart, in case it needs to be in a particular gear or something before I start, but can't think if a reason it would. The Haynes manual's not very informative -obviously, it's a Haynes manual.
The gear lever clamps to a shaft that runs through the engine to the right side where it moves a ratchet & pall mechanism that clicks the selector drum round. So it shouldn't matter what gear it's in when it comes apart, as long as I don't move anything. I hope.

New chain bought from the local bikeshop this evening. 60 quid. It's gold coloured though, which will simply ruin the colour scheme  :)
Apparently a standard XS chain is 104 links. I needed 112 & they had 118 in stock, so I took that. If each link's about an inch long, that'd make about 4" of stretch in the frame, which sounds about right.
I asked about cranked links - Jeez, I've been in the business for 20 years & never seen one. You might be able to find them for Brit chains but not Japs.  :)
It has a rivet link instead of a split one. Never rivetted a chain before. They reckoned the ends of the link pins can be spread with a small G clamp, but if not they'll lend me their tool.

The usual one step forward & several steps back this evening.
With the C thing only a week or so away, it's getting busy at Royal Mail. Already dark each day by the time I finish work. Fortunately I invested in a rechargeable LED light for the lock-up, so if I've got any energy left after trudging the streets in the rain all day, I can do a few bits on the bike.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 15, 2015, 08:20:05 PM
So, chain looped around the sprockets. Although it's 118 links long, you can see at the rear sprocket that it's only a few links over length.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 15, 2015, 08:35:51 PM
I split it, using the chain breaker kindly leant by Mr Olds, but the pin needs punching through the link to remove it & all my tools & my workbench are in Mr Loon's workshop on the other side of town -half an hour away in the evening traffic, (a quick text confirmed he'd locked up for the day anyway). So that'll be a job for tomorrow evening.
The chain's also a lot chunkier than I'd expected. I'm sure they weren't this heavy duty on my previous XSs. So I've got a couple of clearance problems. At the back end it fouls on the stud that the chainguard attaches to. So looks like I'll have to hacksaw the stud off, (no power supply in the garage), file it back as flush to the frame tube as I can without ruining the powder coat, & add a dab of black paint over the exposed metal. I want to keep the chainguard so will try making a curved tab to sit over the frame & slotting over the exhaust mounting stud. Of course, once that's welded to the guard it'll need re powder-coating -again.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 15, 2015, 08:44:13 PM
And at the front end, it fouls on one of the side panel mounting bolt, (bottom rear). Not sure how much sideways movement there is on modern chains, but it's pretty tight to the side of the electrics box. Cutting into that for more clearance would mean fairly major surgery & repainting, but hopefully just removing the bolt will be enough. I think I can achieve that by replacing it with a stud welded to the inside face of the side panel.
I'm also tempted to try a sprung chain tensioner mounted off the bottom frame cross member.

Mr M use a standard split link, you really don't need a riveted chain on a some what "cookin'", not being disrespectful! just fact, motor like yours. We only ever riveted race chains back in the day, although I accept that the awesome torque that many modern Japanese offerings develop now days, well....Just keep a spare in your pocket, she'll be right. The reason the chains "clunkier" is that its possibly an "o" ringed chain, Morrag


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 15, 2015, 08:53:17 PM
Yeah, it is O ringed -new fangled technology to me. I wondered whether I could buy a split link for a heavy duty chain like this. In my far off youth, we all carried spare split links in the pocket of our Belstaffs, along with bits of wire, spare bulbs etc -which makes me wonder if we lost a lot of links. Only remember it happening to one mate once.

Thought it looked like a 116 link run  ;) Must be something wrong with my formula. :-[ ???
Dam'n that's a wide chain. I know it was expensive but perhaps getting a std width Renolds chain would save all the hassle of modifying the bike (and it would be blue/black).


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 15, 2015, 10:03:24 PM
Yeah, I'm wondering if I bought in haste. Can't take it back cos the link's already partly split, but it might suit Tom's or Archie's.
I think the chainguard mount would need modifying anyway but standard width chain would give more clearance at the front end. It's way chunkier than anything I've had before.

From the pics it looks like 530 spec. chain, which is 5/8"x3/8", when a 520 spec. 5/8"x1/4" would have been more suitable, Mr M, as its that much narrower, and more than adequate, provided of course that your sprockets will accept a 1/4" chain width! Can you not re-rivet and take it back to the dealer to swap for the 1/4" width chain? Morrag


Title: Re: Manky's XS650 Yamaha
Post by: Olds on December 16, 2015, 03:59:35 AM
530 should be the std size but 520 conversion sprockets are available.
Think that old fashioned 530 was 13/16" wide at the rivets. o-ring chain is wider by about 1/8" and I believe that x-ring chain is wider still at about 1" overall.
If I remember rightly, to fit an o-ring chain to some bike such as the Norton Commando that had a 530 as standard, you have to convert to  520 sprockets and chain to get over clearance problems at the gearbox.


Title: Re: Manky's XS650 Yamaha
Post by: Dslam on December 16, 2015, 10:05:37 AM
I would think about the 520 conversion and a non O ring chain.
Modern chains are so much stronger (do a little research) and the 520 non o ring should give you the clearance you need.
You may find 530 non o ring OK as it will be about 3mm narrower without the O rings. Try looking up motocross chain. Might save some surgery elsewhere on the bike.
Both my blown 750 and the 500 Triumph drag bikes run 520 to give me clearance past the rear slick.

Post by: Manky Monkey on December 16, 2015, 01:31:16 PM
Thanks guys. O.K, I've ordered a D.I.D 530 chain. I think the chainguard mount would foul on any size chain, so I'll re-think that, but hopefully the slimmer chain will clear the side panel.
Hopefully the bigger chain will fit Tom's XS, which has a black & gold colour scheme.
Really not enjoying either of my builds at the moment & seem to be going round in circles, constantly re-working things. Looking forward to being able to just use them in the Spring.

New chain's arrived. A more "standard" DID 530. Hopefully that'll do the job.

Post by: Manky Monkey on December 18, 2015, 07:40:03 PM
New chain cut to length, (thanks Mr Olds for the use of your chain splitter), & temporarily held with the split link. Temporarily because it's going to have to come off again. I've hacksawed the rear chainguard mount off, so it doesn't foul on the chain any more, but I'm definitely going to have to saw a slice off the bottom edge of the electrics box & modify the side panel -again. Just not enough clearance. Not the end of the World, just another job to do. A very slow, tedious job though, cos I've got no power supply in the garage so will have to sit with a junior hacksaw & a file for several hours & everything around it's already powder-coated & painted, so I'll have to be careful.
Fitted the chain this evening, on my way home from work after a very long & tiring day, delivering everyone's Christmasses. Having resigned myself to doing it, I picked up the hacksaw & CLICK -the rechargable LED worklight ran out of charge & the garage was plunged into darkness. Unlike traditional bulb ones, the LED lights don't gradually dim as the charge runs out, they just suddenly click off without warning. So that made the decision for me -time to go home.
Hopefully I can get this sorted over the weekend & move on.
With the side panel off, I've drawn a rough line with a white Tippex pen where I need to remove a slice of the box.

 :) Yeah, it always happens when you're surrounded by all the little bolts & springs you don't want to lose & you have to try & pick your way out without kicking them all over the place. The garage is behind a row of council houses in the middle of a housing estate, so there's street lights about, but it's suprising how dark it can be in there. I was working by the light of the torch app' on my mobile phone until I bought the new lamp, with an elastic band around it so I could hold it in my teeth!
Having owned half a dozen houses with garages & had the use of a barn with a car lift, plus a huge shed when I lived in Guildford, then Mr Loon's workshop for the last few years, going back to a rented lock-up garage with no power's like starting out all over again. It's not impossible, but just means every job takes 3 times longer & seems to involve taking parts off, working on them somewhere else, then bringing them back. Fine if the vehicles are finished & just need occasional maintenance, but no fun for actually building stuff.

Or better still find yourself a pensioner who has a garage at the side of their house that is no longer used, most have lights and a power socket. We used to have an old boy round the corner who let me use his unused garage to keep our dive boat in, bless him, he wouldn't take any money from us, and always made tea and cake when we were working on the engine. To be honest he looked forward to our visits, was probably the high light of his day, he even had a special stool to sit on and chat to us ::)
The point is there are loads of the older generation that are on their own, who would probably benefit from renting out their garage for a few quid a week. No problem for a fine upstanding member of the community like you Andy, to be recommended to someone.  ;D

 :) You obviously don't know me very well!
I lodge with a little old lady. There's a garage on the side of the house, but she uses it as a utility room, with her washing machine & stuff in there. I'd like to use the bike for commuting to work in the Summer, so will have to approach her about keeping it there, but wouldn't push my luck & work on it in there as well. There are some flats at the end of the road, with a block of decent garages next to them, so at some point I'll put a note through their doors asking if anyone has one they want to rent out, just because it'd be more convenient than the one I'm in.
I've got a small generator, but I leant it to Mr Flap several years ago & haven't seen it since!
I was at Loon's workshop today, so made a bracket to hold the back end of the chainguard, but need to try it for size, mark it, then take it back to Loon's to trim & weld in place.

A bit of post Christmas faffing today.
New chainguard mount welded to the guard & a couple of unwanted holes filled. With luck, the new rear mount should sit over the frame & bolt to the rear exhaust mount. I'll have to take it back to the lock-up now to see if I've welded it in the right place.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 28, 2015, 09:46:42 PM
The front of the chainguard bolts to the recess in the side panel. Again, I need to go back to the lock-up now to see if the bolt holes line up.
I cut the old recessed section out & made up a new one 10mm deeper, which is hopefully enough to clear the chain. First bit of welding I've done for a while.

Finally, a little progress today.
It was my day off so I was at the garage at the crack of lunchtime. I've been trying to repaint the modified electrics box for a week but it's been too cold. Seems to have eventually worked out O.K now, so I was able to refit the drive chain & tension it, then swapped the gearshift shaft for the new one I bought from Yambits, with a new oil seal too. The splines that the gear lever push onto were completely buggered on the old shaft. A previous owner had tried to fix it by cross drilling the shaft & presumably bolting through the lever. Not a lot of metal left around the hole as you can see, so eventually it would shear off. Just as well to replace it while I'm building the bike.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 06, 2016, 06:57:28 PM
At the other end, the shaft operates a spring loaded ratchet that clicks the gear selector drum round. I adjusted this as the manual says, to give an equal amount of movement up & down through the gears. I lubricated everything with engine oil as I went, but even rocking the back wheel to move the front sprocket as I selected the gears, the action seems a bit clunky, taking a good thunk of the gear lever to select the gears, but as there's no other adjustment, I'm hoping that's just because there's no oil in the engine & no clutch at the moment, (the handlebars are being re powder-coated so no lever fitted). I've watched a couple of "How to" videos on YouTube which suggest selection will be much smoother with the engine running too. Ain't technology wonderful. Not sure how to do something -call up YouTube on your SmartPhone & work through it step by step in the garage.
Refitted the clutch, with a new bearing & new friction plates & rather fortunately, Mr Baychimp arrived to see how I was doing, just at the very moment I realised I didn't have a torque wrench for the centre nut. A quick trip across town to his house to collect his & it was done. I replaced the engine side casings on each side, but my LED worklamp decided to run out of charge at that point, so I was just able to refit the kickstart & gearlever before calling it a day.
Next job will be to fill it with oil & see where it leaks out, then, once the handlebars & switchgear are back on, see Nathan, (Galaxie 500), who's going to wire it up for me.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 07, 2016, 09:08:53 PM
Filled it with oil this evening -no leaks so far. Very slightly overfilled but I'm not too worried cos the motor & filters were completely dry & I'll change the oil after the first 500 miles anyway. Got me wondering though -I filled it & checked the level with the bike on the sidestand. The filler's on the right & the dipstick goes right down into the bottom left corner of the casing. With the bike leaning to the left, would the level be higher or lower, or the same, than if the bike was upright? Just curious :)


Title: Re: Manky's XS650 Yamaha
Post by: Olds on January 08, 2016, 07:05:46 AM
It should show as slightly higher than when upright. Once you get it upright and run for a bit you may still need to top up.
If I remember rightly, early bikes (pre 75 ish) had a problem with 'heavy breathing' if filled to the high mark on the dipstick.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 08, 2016, 06:53:32 PM
Yeah, the manual shows less oil capacity for later engines.
Nipped over to the powder coaters after work this afternoon & picked up the re-coated handlebars, chainguard & side panel. Re-fitted the bars & their levers, master cylinder & switchgear, but will leave the chainguard & the modified side panel it bolts to until Nathan has wired it up, hopefully in a week or 2.
The clutch lever feels very heavy but I haven't adjusted it yet so should be better with some freeplay in it.
Working by the light of my LED worklamp -30 quid well spent at the local tool shop.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 10, 2016, 07:57:44 PM
Lots of small jobs today, so not much to see.
First on the list was a trip to the local camping shop for a small gas heater to take the edge off the cold in the garage. Definitely feels like there's snow on the way.
Left engine casing back off to grease up the worm drive that operates the clutch cos I forgot to do it first time around. Then adjust the worm drive & the lever. Clutch is still a little heavy but the plates are still dry & the engine hasn't run yet. Much better than it was.
Adjusted the twin throttle cables until both carb slides lifted in sync, then spent an hour modifying a cable seperator to fit, before deciding it looked tidier without it & taking it back off.
One small spot of oil under the bike which looks to have come from the filter housing, so took it off, added copper washers under the bolt heads & nipped them all up tighter.
Cut the ends out of the handlebar grips & fitted a small bar end mirror on the right & the plug section of the left one to keep it looking symetrical.
Didn't get going till lunchtime today & by 3.30 it was really too cold to work in a lock-up, even with my new heater.
Jobs to do before I give the bike to Galaxie500 to wire up:
Fill & bleed both brakes, (& fix any leaks).
Take the tank back off & replace a few tatty bolts on the cylinder head as well as the oil seals under them.
Fit new oil seals on the points covers, (2 chrome covers either side of the head), set the engine to TDC & adjust the Boyer electronic ignition pick-up.
Take the new sidestand spring back off & figure out which way up & round it should fit to keep the stand up & down as needed.
Touch up & polish out various scuffs & chips in the black paint.
I also want to fill a couple of tiny dings in the tank & blow it over in another coat of aerosol paint. Anyone know of a sealant I can put on the fuel tap threads to make sure they don't leak? They're tapered threads so shouldn't, but I bet they will.
Although there's oil in the motor now, I haven't tried turning it over on the kickstart yet. Might wait till it's wired up & it can be fired up properly. Not far off now.

I’d suggest before starting the motor, remove the plugs (so the engine turns nice easy) and turn the motor over quite a few times to get the oil round. Lotsa kicks on the kick-start or simply get a mate to help push the bike round the yard a couple of times with it in 2nd or 3rd gear.

An alternative (sometimes useful during a build) is to connect an electric/battery drill with a socket onto the crankshaft bolt/engine sprocket.
A set of starting rollers make things really easy, but unfortunately they’re not usually in most folks tool boxes!

Clutch plates - Bit of a ‘trick’ of some of the grass-track guys used was to put a spare set of clutch plates submerged in oil (in an old biscuit tin or alike) to take to meeting so they were ready to go if needed.

Nathan thought he could wire the bike in a couple of days, but it depends if he's free. Last I heard he was rewiring a Shelby Mustang. I've got a few afternoons/days off of odds & ends to do, but nothing that'd stop him wiring it. It's my birthday a month today -it'd be nice to have it running & rideable by then :)

Met Mr Galaxie500, (Nathan), at the garage this morning & we had a chat about wiring the bike up. He's wired several cars before but never done a bike. Once he'd been shown where the various components were though, he seemed confident enough. He wasn't sure about a price but thinks it'll take about 2 days. Should be able to do it in 2 weeks time. I know he'll do a good, tidy job & I'd rather give the money to someone I know than a stranger.
Once he'd left, I spent a few hours replacing oil seals & rusty bolts, as well as setting up the electronic ignition sensor. It was seriously cold in the lock-up though, so by mid afternoon I'd given up for the day, so took the fuel tank over to Loony's workshop. It's a new tank but had a couple of small dings in it that didn't show up till it was painted, as well as some marks where it was stamped out in the factory. Loon ran a quick skim of filler over it & will spray it in filler/primer tomorrow. Just as well he did it cos I couldn't feel my fingers by then. S-o-o cold :(

Don't know if you're aware of expandable plastic braiding, but it can be a really tidy way of finishing off the wiring.

Some variety of colours are available, and a bit of heat-shrink to terminate the end makes a neat job.

Available from various suppliers including a certain on-line auction site.

 :) the Pop's done with that. Works well. There isn't much exposed wiring on the bike, but I'd quite like it to match the Pop.
Last of the tatty engine bolts replaced & copper washers/Dowty seals fitted where needed. Meanwhile Mr Loon's rubbed down & primed the tank. Thank you Sir.

Damn it's cold out there :(
Seem to be going round in circles, re-working parts several times. Rear mudguard taken off again & delivered back to Mr Loon for re-painting, (had a run in it & a couple of scuffs where I modified the electrics box. Easier just to repaint it off the bike).
I've been turning the engine over on the kickstart. Seems to turn smoothly enough, but circulating the oil has produced a small drip somewhere under the motor. I try to avoid using gasket goo, so anything I've worked on has gone back together with dry paper gaskets. Need to get underneath with a mirror on a stick to track it down.
Still got the brakes to bleed, but that's about it till it's wired up.
The date for this year's Bike Shed show in London City's just been announced. 28th & 29th of May. It'd be nice to go on a bike instead of in my commuter car, especially if the gents from Loon's workshop manage to get their bikes done too. Roll on the Spring!

If you fitted the paper/card gaskets dry, the leak may stop as they tend to swell slightly on contact with oil. I prefer to oil or grease gaskets prior to fitting or use a very thin coating of Wellseal.

Post by: Manky Monkey on January 17, 2016, 10:50:36 PM
Might be more than one leak, but I've tracked one down to the oil strainer, (small round casting inset in the righthand side case, with the frog's head engraved on it). It's not a standard Yam' casting. It was machined by the engraver's mate because the original was too thin to engrave. Oil's weeping out of it, down the main casing & collecting under the motor. Where do I buy Wellseal Dave?

I'd planned to work on my truck today but lots of people working on their projects at Loon's workshop, so I gave it a miss & went back to the bike.
Sidestand issues finally sorted -had the return spring bracket on upside down. It'd only work with the original tatty spring though, not with the nice new stainless steel replacement I bought.
A few scuffs in the black powder coating polished out, then I tackled the brakes. Front one's now filled, bled & fully operational. As I expected though, the rear one's giving me problems.
I've got a standard pedal pushing into a standard master cylinder via a modified linkage, with a small aftermarket remote reservoir. No sign of fluid movement in the reservoir when I pump the pedal & no fluid at the bleed nipple. I've already changed the hose from the cylinder to the reservoir once because it had a kink in it. So I guess I'll start by removing the reservoir & running fluid into the cylinder directly down the hose. If there's no movement then, I'll take the cylinder apart. My brother built the linkage so I'm pretty sure it's got full travel, but it may be a knackered cylinder. Not the end of the World if I have to buy a rebuild kit or even a replacement. Quite enjoying tinkering with a bike again :)

Not sure where you can get Wellseal locally. Ebay I suppose. It's messy to use but great stuff. My BSA A10 and RE Bullet were both totally oil tight after rebuild.

Sorted. Thanks chaps. I always forget about Cromwells. I'll buy another paper gasket for the leak. Treated myself to a couple of new hammers too cos they were pretty, (£3.50 & £5.50).
New bike battery filled with acid, (it comes seperately these days), but it needs charging before use. Hopefully Nathan can do that for me while he's wiring it cos it's a bugger to get off the bike -whatever idiot designed the battery box built it to bolt up from underneath, but made it taller than the gap between the frame & the ground so the bike has to be jacked up to get it out.

It was originally a BSA design I'm told.
No progress on the bike today but I stopped at the garage this evening to drop some tools off -oh Gawd, what's that that's leaked all over the handlebars?! Looks like it's reacted with the powder coating & turned into solid, shiny lumps ...turned out to be water that'd dripped off the roof & frozen. I hate Winter.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 24, 2016, 08:57:37 PM
Opened the garage door this morning & everything was dry, but before my very eyes a mist of condensation formed on all the metal surfaces. Guess it was the change in air temp. You can see the gloss black frame's misted with moisture here.
I'd gone to have another go at bleeding the rear brake. Mr Olds had suggested the fluid in the reservoir might not move if it's lower than the caliper. Hadn't occured to me, but sure enough it is lower by a couple of inches.
The reservoir's the small black billet ali' cylinder in the middle of the electrics box. Even if moving it doesn't cure the problem, it'll be tidier anyway so would be handy to get done before Nathan gets in there to wire the bike up. I'll mount it off the top coil mount, (the grey bit at the front of the box).


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 24, 2016, 09:09:21 PM
So I took some measurements & headed over to Mr Loon's workshop to bend a bracket up from 20mm wide flat strap.
Also took the kickstart lever. It flops around on it's mount a bit & would drive me crazy while I'm riding, so I bought a rebuild kit for it -a new spring, ball bearing, E clip & washer. A simple job once the old ball bearing's out but it was trapped by a burr on the edge of the hole it sits in. Took an hour of carefully grinding flats on the ball bearing with an angle grinder to free it. Clamping the lever in the vice damaged the powder coat so I flatted it back & Mr L will respray it when he does the rear guard.


Title: Re: Manky's XS650 Yamaha
Post by: kapri on January 25, 2016, 09:51:46 AM
I agree with Dave you are trying to force fluid uphill and there is the ideal opportunity for it to bleedback as well. You may to go to a 2lb residual valve if you lose full travel over night.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 25, 2016, 09:25:35 PM
Hmm. I remember the trauma of sorting the Pop brakes out only too well Kev!
Well I drained the reservoir this evening, (wicked the brake fluid out of it with some paper towel), then disconnected the hose from the reservoir to the cylinder. The cylinder's below the reservoir, so even if it wasn't working, there should've been fluid in the hose. There was, but definitely not a full hoseful. No blockage in the reservoir outlet so it should've filled the hose with fluid just by gravity. Odd.
I've got to modify the bracket I made & cut a longer piece of hose then I'll fill it again. I suspect the pushrod that operates the cylinder isn't pushing far enough to pump the fluid cos it's too short, or isn't returning enough to allow it to refill from the reservoir cos it's too long.


Title: Re: Manky's XS650 Yamaha
Post by: BikerGran on January 25, 2016, 09:40:04 PM
I had a problem like that with the trike and had to get the pushrod modified.


Title: Re: Manky's XS650 Yamaha
Post by: Olds on January 25, 2016, 10:00:24 PM
Could be as simple as a bubble of air stopping the fluid from going down the tube. Tapping the side of the tube usually shifts it, but I once had to fill the master cylinder and tube using a syringe before connecting the resevoir. Just a thought.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 25, 2016, 10:04:42 PM
Yeah, we discussed using a syringe to prime the system the other day. Hadn't thought of air in the hose. Good point.
My brother & I had to guess at it when we set up the brake linkage. Ideally the rod would be adjustable. The pedal doesn't feel like it has any freeplay before the rod makes contact with the cylinder piston, so I reckon the piston isn't returning enough to draw fluid from the reservoir.
I'll remount the reservoir & go from there.

Brake fluid reservoir mounted a few inches higher inside the electrics box with a new length of hose connecting it to the master cylinder. It's now slightly higher than the caliper.
Pedal linkage disconnected & the master cylinder operated with a screwdriver temporarily.
Result-
it's definitely pumping fluid through the system & the piston seemed to travel less as the air was bled out at the caliper, suggesting it was building pressure as it should.
However, when I reconnected the pedal & linkage, the pedal goes right down without operating the brake at all.
It got too dark to make out what was happening this evening, but I assume either the operating rod's the wrong length or there's just a lot more leverage with the pedal fitted. I'll try bleeding it with the pedal tomorrow.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 29, 2016, 06:58:45 PM
Decided to buy a rebuild kit for the rear master cylinder. Probably not been touched since it was new in 1980, so worth doing & at least it'll eliminate that as the problem.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 09, 2016, 08:46:51 PM
Cylinder rebuild kit's arrived from the States, so I removed it from the bike this morning, (a bit of a faff cos it's tucked under the electrics box, between the top & bottom runs of the chain, with a complicated pedal linkage attached to it).
Stripped it & rebuilt it this afternoon, then refitted it this evening.
I'd literally just popped the dust cap off the rear caliper bleed nipple when click -the LED worklamp in the garage ran out of charge & I was plunged into darkness. So I'll charge it up this evening & have a go at bleeding it using the pedal tomorrow. I've had fluid bleeding through the system when I disconnected the pedal & pushed the cylinder piston with a screwdriver, but couldn't get enough leverage on it to bleed it properly. So if it doesn't bleed now, the problem must be in the linkage between the pedal & the cylinder.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 10, 2016, 09:26:18 PM
No fluid movement when I use the brake pedal to bleed it. So it looks like the rod that pushes up into the master cylinder's too long. It begins moving the piston as soon as I touch the pedal -I'm guessing there should be a couple of mill' of free play, which would make sure the piston's fully returning & replenishing the cylinder with fluid. Too dark again this evening to remove the linkage, but I guess I'll have to shave a little off the end of the rod & see what happens. 


Title: Re: Manky's XS650 Yamaha
Post by: Olds on February 10, 2016, 09:43:46 PM

Post by: Manky Monkey on February 10, 2016, 09:58:46 PM
I was chatting to my brother, Mr Brock, at his workshop in Wiltshire this afternoon, & we spoke of that very thing.
He pulled  a 6mm fitting out of a drawer, (possibly a brake pipe union), & said One of these, (a short length of hex bar bored & tapped to M6), with a length of 6mm stud in each end with locknuts, would do it. Stupidly, I didn't pocket it before he put it back in the drawer. I've got to go back next week though. The pushrod's only maybe 3" long, so not a lot of room for adjusters & once I know the necessary length it won't ever need adjusting again, so probably easier to trim the original down until it works -assuming it does. Just time consuming as it means constantly removing & refitting the linkage, then trying to bleed it each time. I'll get there eventually.  :)

If you get an coupling nut for alltread bar they are about 40mm long X 10mm and treaded for M6. And a with piece of alltread you can determine the length you need then make up one in one piece .

Sounds like a threaded bar (studding or all-thread) connecting nut. Looks like a normal plain nut, but much longer. Screwfix have them in stainless steel @ £2.49 for a pack of 10.

Post by: kapri on February 11, 2016, 09:31:54 AM
Normal practice for brake pushrods is slightly free ie about 1mm ,just  enough to feel as slop. This allows for heating = expanding of brake fluid without locking itself on as it expands


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 11, 2016, 09:06:21 PM
Hadn't thought of the expanding fluid -I just assumed a little clearance would make sure the piston fully returns.
Yup, sounds like that's what Steve showed me. As I said, it's just a fiddly, time consuming job & I need some daylight to do it in, but hopefully it'll cure the problem.

Post by: Manky Monkey on February 14, 2016, 10:44:37 PM
Back to Steve's workshop this afternoon to collect my bike parts -there were some scuffs in the rear mudguard & a few other small parts needed painting, he just happened to be painting parts for his race car in black, so he did mine too. Thanks bruv.  :)
Mudguard & kickstart re-fitted this evening, then I had another go at the back brake. With the rebuilt master cylinder, I now have what appears to be a working brake, but the pedal's travelling right to the floor before it works. So just to see what happens, I'll pick up a pack of bicycle ball bearings from Halfords tomorrow & sit one on top of the pushrod in the master cylinder to temporarily extend the rod. Maybe the brake will bind, maybe it'll work perfectly. we'll see.


Title: Re: Manky's XS650 Yamaha
Post by: kapri on February 15, 2016, 08:52:47 AM
Is it  possible you need a shorter pushrod ? ie you are not using the full swept volume of the m/c and not allowing the fluid to replenish the cylinder hence you are always moving too small a volume to operate the brakes correctly and fully.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 15, 2016, 02:02:38 PM
Yeah, that was my first assumption Kev. Not really sure, but bunging a ball bearing in, (anything would do but I've just bought a pack from Halfords for 2 quid), will eliminate that possibility first.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 16, 2016, 08:34:33 PM
Not a particularly good afternoon.
I added a 6mm ball bearing on top of the pushrod that operates the master cylinder. Result the brake was binding.
So I left the bearing in place & trimmed 3mm off the pushrod. Result -the brake works but only right at the end of the pedal travel. Too far to be comfortable to use & I'm sure the MOT man would call it excessive travel.
I messed about, trimming a little more off the rod, adding a 2nd ball bearing -no improvement.
Really fed up with this now. Apart from the wiring, it's the last bit to sort out & it's fighting me all the way. I enjoy fabricating stuff but the faffing about trying to make it work ain't my thing. To top it all off, while leaning over the bike & straining to line up the cylinder with it's mounting holes, I suddenly got a nose bleed. At that very moment Big Darren strolled in from his garage next door
-How's it going?
I looked up, dripping blood ....not well, not well.
So I've been to Screwfix Dave, bought a pack of those threaded joiners & found a 6mm bolt in my spares box. Tomorrow I'll weld the joiner to the clevis, in place of the pushrod & make an adjustable rod.
If that fails I'm seriously thinking of cutting the whole damn brake assembly off the frame & fitting one of those direct push Harley cylinders, as I should've done in the first place, though it'll mean major surgery to the frame & repainting.

I'll take some photos today Kev.
Standard Yamaha pedal, standard Yamaha master cylinder.
The pedal's attached to a cross shaft, running across the frame in a tube with bronze bushes at each end.
At the other end of the shaft is a short arm with a return spring attached to it. The pushrod's welded to a clevis that pivots on the end of the arm, (actually a modified Pop brake rod).
Push the pedal, the shaft turns, the arm at the other end turns & the pushrod pushes up into the piston in the master cylinder.

Pedal ratio! Yeah, I'm guessing it'll be that, simply because it'll be the most awkward bit to fix. If I make that arm longer, I'll have to move the master cylinder, which'll mean cutting the bracket off the frame, which'll mean taking the chain off to reach it. Then I'd need a new brake hose & probably have to modify the electrics box again. Really hope it isn't that.

On the other end is a modified Yam' arm, attached to the shaft by a Scotch lock, (the end of the shaft & the arm are drilled & tapped & held together by a small grub screw). Below it is a return spring, Yamaha, but not sure where it was originally fitted.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 17, 2016, 08:40:25 PM
A modified Ford Pop brake rod connects the arm to the master cylinder above it, (again, standard Yam'). I've replaced the solid pushrod with an adjustable one, but in the photos it's not welded, just sat in place for explanation.


Title: Re: Manky's XS650 Yamaha

Fitted to the master cylinder are a black rubber hose going to the fluid reservoir, a black braided brake hose going to the rear caliper & a hydraulic brake light switch.

Here's the small aftermarket fluid reservoir, bolted to a bracket that hangs off the top ignition coil mount inside the electrics box. It's about 2" above the height of the caliper, though the Harley type ones sit much lower & still work fine.

Is the RH foot peg mount acting as the return stop ? And have you tried moving the brake pedal around one spline to give more angle to the clevis arm ?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 17, 2016, 08:50:36 PM
Yes Dave, it stops against the underside of the footpeg. You mean drop the pedal one spline to give more travel on the arm? Nope, haven't tried that yet.
The reservoir has a small sight glass in the side & can be filled through the access panel under the seat, (the red bit's the Boyer electronic ignition module).

The pedal measures 225mm from shaft centre to pedal pad centre. The arm is 40mm centre to centre. That gives a pedal ratio of 5.625, (I didn't cheat & use a calculator for that, honest).

Generally looks fine. As long as you have enough movement and the piston in the master drops to the point where the port to the reservoir is open, then it should work. I assume that there is a vent in the reservoir cap.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 17, 2016, 09:32:10 PM
Not sure there is Dave. It has a 2 part rubber seal under it. I've tried the brake with the cap off while bleeding it though, with no difference. I'll try moving the pedal on the splines tomorrow & will refit the welded adjustable push rod.


Title: Re: Manky's XS650 Yamaha
Post by: morrag on February 17, 2016, 09:41:24 PM
Mr M your set up looks more than adequate to me, with plenty of "leverage", brake arm to cross shaft. I suspect your M/C is not doing its stuff, but to perhaps prove it, either way, take 2' of 1"x1/4" flat m/s bar, or whatever you have to hand, drill two holes, one at the end for the simulated pivot point of the cross shaft, and another to accept the master cyl. clevis. Now you an arm you can operate by hand, with all the mechanical advantage you could require. For test purposes leave the return spring off, the cylinders piston should be held in location by a circlip anyway, so that will be fine. The rear calliper will be fairly small and requires little in the way size, for the moving column of brake fluid from the M/C, to operate it, ( I assume the slave cylinder is "tickety-boo?), worth a try don't yer think!!.... ???

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 17, 2016, 10:10:52 PM
Hiya. Both the caliper & master cylinder have been rebuilt & appear to work fine. Slave cylinder -what slave cylinder?
I'm fairly sure the master cylinder piston's being pushed it's full travel but will fit the adjustable pushrod & try & measure the travel compared to pushing it with a screw driver. I'll be amazed if adjusting the rod up or down just a couple of millimetres makes much difference to the excessive pedal travel, but will try it.
Dave's suggestion of turning the pedal on the splines sounds logical so I'll give that a go first.


Title: Re: Manky's XS650 Yamaha
Post by: Olds on February 17, 2016, 11:05:49 PM
2mm too long and the master cylinder may not pump up. 2mm too short and that's 12 mm at the pedal before it starts to do anything at all.
One other possible problem might be misalignment between disc and caliper causing the pads to be pushed back into the caliper by the disc or caliper mount flexing. Had this to a degree on the trike until I got the carrier spacers exactly right. Though I doubt it could be bad enough for what you are experiencing


Title: Re: Manky's XS650 Yamaha
Post by: morrag on February 17, 2016, 11:20:59 PM
Oops, for calliper, read "slave" cylinder!! But remember, that the amount of effort achieved with hand pressure on conventional twin disc front brake set ups, is more than enough in that context, then think of how much your able to apply with your current, very neat, foot operated, single calliper rear brake, therefore, be sure that both cylinders are doing the biz. before chopping things about, Morrag


Title: Re: Manky's XS650 Yamaha
Post by: kapri on February 18, 2016, 08:43:29 AM
Look at it another way, how much has changed from standard Yam? Have you checked the ratio on a standard Yam pedal? Are you SURE they are the correct m/c and caliper  ?  If you remember on the Pop the main brake problem was traced to too small an mc for the requirements of the calipers/ slaves. Is the rear caliper fitted in the OEM position or has it been moved round ?

Not had a chance to do anything today, but yes, standard Yam' disc & caliper, mounted in the conventional position. The pedal & the operating arm on the other side are both standard Yam length, so the pedal ratio's as standard.
With the back wheel off the ground, I can spin it & stop it using a screw driver to push the master cylinder piston. When it's hooked up to the pedal, the pedal goes right to the ground before it just about stops the wheel. It's got to be a combination of the pedal in the wrong position on the splines & the push rod being the wrong length.
Hopefully I'll get time to take another look tomorrow.

Ta dah!
Brake fixed. Jeez, what a frustrating job. Thanks for the PMs & posts chaps. As predicted, it turned out to be simply a mix of the pedal being one spline out on it's shaft & the push rod being the wrong length.
Lifting the pedal by one spline improved things. Two splines locked the wheel solid. Back to one spline, then gradually increase the length of the adjustable push rod. Now the wheel's on the point of binding but still turning & it stops with a ressonable push of the pedal. I think once I've ridden a few miles & everything's bedded in, it'll need adjusting again, but I'm happy with it now.
Push rod modified with a hex stud joiner welded to it, as suggested, & a short length of 6mm stud & a lock nut.

Right hand side panel fitted -Nathan, (Galaxie 500), will need it to wire the bike up cos the ignition switch is fitted in it. I'll ask him to use a multi pin plug connector on it to make removal of the panel easier.
I'll leave the left panel, exhaust & saddle off for now to give him more room to get in the electrics box.

I'm never sure if the honey-combed lens of the rear light counts as a reflector. I don't think it does but I need one for the MOT. Not keen on the little stick-on plastic ones you see stuck on the corner of people's number plates, but I saw some really nice. (& really expensive), glass ones the other day. Might fit perfectly in the hole in the right hand indicator below the tail light.

Worth thinking about - Just had a word with a pal who does bike MoTs and asked about your reflector, he said it should be located on the centreline of the bike.

Me too! 8" baffles in each pipe so I'm hoping they're actually reasonably quiet, (I'd like to use it for commuting to work over the Summer so it needs to be neighbour friendly or I'll have to push it to the end of the street before starting it).
I did remark to Darren that it's a good job he's 100% honest cos he loaded my bike then Marcus's in his van, more or less on his own, in just a matter of seconds. I need to invest in a decent lock at some point.

Not a bad idea - for some reason there seem to be an increasing number of bike thefts at present - maybe it's just that I'm hearing about them, but nothing is sacred!  It's not just high value sports bikes getting stolen for parts and small bikes which are ragged till the fuel runs out then torched, all sorts of stuff is getting nicked!

The tank needs re-painting then fitting, along with the exhaust. That's about it. Dreading firing it up. It hasn't been run for 5 or 6 years & never with the Amal carbs. Should be interesting.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on April 07, 2016, 07:03:55 PM
Day 2 & it's finished. Just needs an LED for the high beam warning light in the top of the headlight shell & testing of everything.
I'll take the right hand side panel & exhausts over one afternoon this week, then it's just the tank & some fuel.
I'm sure I've forgotten something but can't think what.
It'll probably leak all it's bodily fluids, smoke heavily & backfire like crazy, but so do a lot of my mates.  :P

I have no idea what anything inside that box does.
Yeah, might run on one cylinder, or not at all. Might take 6 months to get the carbs set up properly or fix the oil leaks -did I mention I plan to ride it to London next month?!
Nathan had to fit relays for the handlebar switch because the wires were so small as well as re-wire the ignition switch cos it didn't work the way we assumed it did -no On/Off switch for the lights, so the ignition switch will be Off/On with sidelight/On with low beam, (sidelight on all the time as a lot of custom bikes are).
Apart from the wires being a bugger to run down through the frame tube behind the engine, no problems to report.
Testing next.  :)


Title: Re: Manky's XS650 Yamaha
Post by: Tony oily bike on April 08, 2016, 12:36:24 PM
Looking good, once the electrics are tested and the last bits bolted on, I suggest you spin the motor (plugs out to make it easier) to get the oil well circulated as its been standing for a long while.
Also suggest that little bit of oil down the bores won't do any harm re rings/bore lubrication, ok it'll smoke a bit once started, buy so what.

If the kill-switch when set to 'off' allows the starter to spin the engine, good, but if doesn't, to be on the safe side when simply spinning the motor its worth having the plugs earthed to allow them to spark as some electronic units don't like 'not being able to spark'.

What could possibly go wrong!

Saw Archie this afternoon. He was heading to the barn to work on his own bike, so I was able to spend some time there too.
Right hand side panel bolted on. Chain guard fitted, (the front end attaches to the side panel but with the electrics box full of wires now, it was a bugger to reach the mounting bolt). Exhausts fitted with new gaskets & top panel of the electrics box dropped in place before the saddle went on. I also bunged a small glass reflector in the hole in the middle of the right hand rear indicator. I suspect that might vibrate out on the first trip, but I have a spare.
Mr Loon's got the tank now so just the headlight lens to go back in once the high beam warning light's fitted, left hand side panel & the tank once it's painted. Very nearly there.

Continuing my theme of buying or reworking every part at least 3 times, I've decided to change the speedo for a smaller one. No reason, I just preferred it. White face instead of black cos it'll be less obtrusive against the ali' fork leg & cos they're back lit & the white ones show up better at night. Stainless body instead of chrome & LED illumination instead of a bulb.
I've also bought a 90 degree angle drive for the cable from Speedy Cables in Wales. It screws onto the existing Yamaha speedo drive unit & turns the motion through a tight bend. Hopefully the cable will then run more or less straight up the back of the fork leg instead of the current twisty S shape. Of course, now the cable I had made will be too long, so I'll need another.
Spent an hour in the lock-up this evening modifying the mounting bracket that came with the new speedo to suit, then put it in the vice to bend it to 90 degrees, tapped it with a rubber mallet & ping, it snapped in half. *sigh* -down to B & Q for a length of aluminium flat strap. I'll make another mount tomorrow.

Short length of aluminium tube, just as a guide for the inner cable to run in, packed with grease. Just propped in place here to check the fit. The ends need to be flared to retain the nuts that screw onto the speedo & drive. First attempt, using a brake flaring tool, just split the tube. Another tube cut to length, so next I'll try a punch & hammer. Will look much tidier than the old cable if I can get it right.

Warmed the aluminium with a butane torch, (thanks Tom), then was able to work a punch around the end, pushing it out bit by bit. Not particularly pretty, but won't be seen under the screw on collars. It sits between 2 fixed components so can't really go anywhere anyway.

Then polished with a cloth & a big squirt of cutting compound. The bike's supposed to compliment my truck, which has a satin finish, but I think I'll leave the tank in gloss for now, at least until the truck's back on the road.
Cap & twin taps fitted.

Speedo "cable" finished. Lined with a length of PTFE pipe & buffed up a bit. Hope it works.
Nipped across to the Guzzlers car club barn, (about 2 miles across country from Loony's workshop), to fit them, but nobody was home, so I'll try again tomorrow. Got to drill & tap the back end of the chainguard to bolt it to the frame cos I'm not happy with the current fixing, add the tank & speedo cable, then check with Nathan that the electrics are all hooked up & ready to go, (don't want to be kicking it over for an hour then find the coil's not connected or something). Then I guess just put some fuel in it & see what happens. The carbs will need some adjusting, which isn't really my thing, but other than that, more or less ready to go I think.

Whoo &, as you so succinctly put it, Hoo.
Tried the Guzzlers place again 3 times today without success. Anyone would think they've got lives beyond messing about with old motors or something. I haven't got a phone number for any of them except Nathan & I think he's been away this weekend. Won't get a chance to try tomorrow, so will be the middle of the week sometime now.
Last time I was there I put some oil down the bores & turned the engine over on the kickstart for a few minutes, (until I ran out of energy -not so easy when I'm 54 as it was when I was 18). Assuming the fuel reaches the carb & the coil sparks, hopefully we shall have life soon.  :)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on April 28, 2016, 04:52:42 PM
After a week of trying the barn every time I was passing, I finally caught some of the chaps there this afternoon, so had an hour or so to work on the bike until they locked up & went home. Spent most of that fiddling with the speedo cable though. It was slightly too long, because flaring the ends didn't take up as much length as I'd thought it would, & slightly the wrong angle, because I'm stoopid. Lots of tweaking eventually sorted it, but then the inner cable unravelled itself -speedo cables are made from a tightly wound coil of wire with the ends soldered or brazed, then filed to a square profile. I'd cut my old cable to length, then just run an angle grinder around the end to square it off. Hoped to get away with it, but just turning it by hand unravelled it. So now I need to find an old speedo cable, cut it to the right length & find someone who can do the soldering business for me. A small job, but as always, one step forward, one step back.
So while the guys were packing up for the day I bunged the tank on so that it at least looks like I've made some progress.
Apart from the cable, I need to cut the fuel pipes to length & hook them up to the tank, bolt the back end of the chainguard down securely & fit the headlight lens -strangely, the glass has separated from the reflector bowl. Never seen that happen before, but I've got some black mastic adhesive which should fix it.
Probably Saturday before I get a chance to continue now. So a tiny weeny bit of progress, but that's better than none.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 03, 2016, 07:22:35 PM
Right then, I need to call upon the collective Manky wisdom of the forum.

Been trying to start the bike today, with no success. The most I've achieved is a cough from the left carb when petrol was squirted directly down the carb mouth. A couple of odd pops, but no other sign of life at all -& I'm knackered from kicking it over. Stoopid idea to remove the electric start.
So, current state of play:

Battery's new, charged & showing at least 12 volts.
Plugs are new & correctly gapped, (25 - 28 thou').
Plugs are sparking when taken out & laid against the cylinder head, (both plugs are fed by the same twin lead coil).
Boyer electronic ignition module must be working cos the plugs are sparking. The XS uses a Wasted Spark system, (both plugs fire at the same time as they're fed by one coil).
Electronic ignition trigger unit's correctly set to Top Dead Centre.
Plugs appear dry, but squirting Easy Start down the plug holes doesn't seem to make much difference, (haven't tried fuel down the plug holes yet).
When the fuel taps are opened, fuel immediately leaks from around the carb tickler buttons, suggesting the floats are too high & the tabs that push the valves shut need bending slightly.
Carb slides are lifting when the throttle's opened, but the left one was sticking open at first. Seems O.K now. No choke slides fitted.

So it appears there's no fuel getting to the cylinders. Am I missing something? I had several Triumph Bonnys with these carbs when I was a teenager, but I can't remember what I did yesterday, let alone 35 years ago. Besides which, fault diagnosis & tuning have never been my thing.
Any suggestions?

For those that like to know these things, these are the carb details:

MK1 AMAL 930 concentrics

Throttle Valve #3 1/2. ( Part No~40-928060/3.5 )

Main Jet #140.( Part No~40-376100/140 )

Needle Jet #106.( Part No~40-622122/106 )

Throttle Needle

(2 Indent) ( Part No~40-622124 )

The needle position is set to the 2nd groove down, (midway).

I know bugger all about bikes but if that were a car I'd say you have the wrong TDC ie it's not on compression stroke.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 03, 2016, 07:43:48 PM
The pistons travel up & down together Kev -not one up while the other's down. So only one top dead centre. You can buy kits to split the crank & re-phase the piston travel, so one's half way up when the other's at TDC. Supposed to reduce vibration & make smoother power, but I'll be happy just to get it running.

Hi Andy,
What ign system you using. I presume a boyer? If I remember rightly you set it up so the white dot lines up in the hole on full advance and the box retards the ign towards tdc at low revs so you may have set it to fire before the inlet valve has shut hence the spit back. Recheck the instructions for the ignition system you have regard advance.
Take the plugs out and shove your thumb over one plug hole and check for compression (stuck rings or valve not closing) do the same the other side, assuming all is ok on the compression front, drop half a teaspoon of fuel down each bore, plugs back in and kick it over, if it spits back out of the carb then the timing is out.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 03, 2016, 09:29:48 PM
Yup, Boyer. White dot showing in the hole in the back plate.
Definitely got compression.
Looks like some fuel down the bores tomorrow then.  :)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 04, 2016, 10:02:47 AM
So. Both pistons travel up & down together.
Both spark plugs are fed by the same coil.
So the 2 plugs fire at the same time, ("wasted spark").
It's just the camshaft set-up, opening the inlet valves at the appropriate times, that feeds the fuel/air mix in to one chamber then the other, that makes it fire on one cylinder then the other.

That means there's only one Top Dead Centre & one points opening, (or in my case electronic pick-up), firing position.
If I put fuel down both bores it'll presumably fire on both cylinders at the same time? But one will have the exhaust valve open when the other's shut?
If it fires like that, where do I go from there? At the moment the carb float bowls are flooding, (remember they're old mark 1 Amal British carbs) so there's definitely fuel flowing from the tank to the carbs.
If I'm getting a spark on both cylinders & it fires with fuel squirted down the cylinder, the carbs aren't feeding the cylinders? Lift the needles in the slides? Just trying to think ahead. I'm not a mechanic & although I've had half a dozen XSs over the years, I have a terrible memory & really can't remember the set-up from previous bikes.


Title: Re: Manky's XS650 Yamaha
Post by: Olds on May 04, 2016, 10:39:43 AM
Not having chokes will not help. Are the pilot jets and the two drillngs each carb clear ? Did you wash out the tank before filling with fuel ? Though the filters should stop gunk getting to the jets. Have you set the slide stops ?


Title: Re: Manky's XS650 Yamaha
Post by: Dslam on May 04, 2016, 10:41:55 AM
I am pretty sure you may have set the timing to fire at TDC. It should be X degrees before TDC.

Slide stop or idle adjustment screw. Not the mixture adjuster. 1 1/2 to 2 turns in after it starts to lift the slide.

Post by: Manky Monkey on May 04, 2016, 05:50:20 PM
O.K, first job was to re-set the timing to suit the Boyer electronic ignition. As Andy surmised, I had it set to the Haynes manual directions for points ignition. It's now at the Full Advanced setting.

The link Andy posted says:
Set the rotor TDC mark (#4) to line up with the line at # 3 in the photo. Number 3 is the total lead mark where the timing is set. All you do is turn the crank with a 17mm socket to line up #3 and #4 above, and set the white dot on either magnet in the timing index hole and that's it. Number 2 was used for setting the points, and number 1 indicates when the pistons are at top dead centre.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 04, 2016, 05:52:30 PM
So here's mine.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 04, 2016, 06:21:27 PM
Result: it fired -hurrah! Then it died -boo.

Spent the rest of the afternoon fiddling with it, but have reached the point where I'm going round in circles & confusing myself as to whether the changes I make are making it better or worse. The ignition seems O.K now. Think it's down to carburation -yeah, I know, self inflicted problems.

The floats were sticking & causing the carbs to flood. Took the float bowls off & there was a small amount of crud in the bottom of them -I rinsed the tank with a small amount of petrol before fitting. It's brand new, but has been sitting in a workshop full of grinding dust for quite a while. There's an inline filter on each fuel line. Each carb is fed by a separate fuel tap from the tank. No linking pipe between the float bowls, but there's a balance pipe between the 2 inlet manifolds. So I wiped out the bowls & cleaned the floats & float valves. That seemed to cure the flooding, so presumably just sticky valves through lack of use.

Put a gallon of fuel in the tank. The mixture screws are set to 1 1/2 turns out from the fully in position. The breather holes are clear Dave & the idle screws are set to 1 1/2 turns in after I could feel movement in the slides as I opened the throttle. A previous owner of the carbs has punched a couple of notches into the ali bodies, which seem to line up with the screw slots in these positions, so I guess they're more or less right.

After an awful lot of kicking, (what muppet decided to remove the electric start!), I had it running 3 or 4 times during the afternoon, but only for a few seconds before it died. The longest run was the first time, after I'd squirted fuel directly into the plug holes. Winding the mixture screws in or out didn't seem to make much difference. Blipping the throttle didn't seem to keep it running & winding the throttle cable adjusters in or out didn't seem to make any difference either. I've had a problem with fuel feed on a Triumph in the past which turned out to be my fault for blocking the fuel cap vent hole with chrome cleaner. So I left the cap off to see if it would keep running. No difference.

The carb tickler buttons are working, with fuel running out of the overflow holes underneath them when they're pushed down. So the float bowls are filling, but I'm guessing not enough fuel/air mix is reaching the cylinders?

So where do I go from here? The throttle slide needles have 3 positions & are currently in the middle one. Should I lift them up to the high position? Would that allow more fuel in? As stated earlier, I'm running the needle & jet sizes supplied by the guy who cast the inlet manifolds. They're the sizes he runs on his own XS, so should be about right. 

 


Title: Re: Manky's XS650 Yamaha
Post by: Clive on May 04, 2016, 06:31:17 PM
Can't quite see in the pic, but is there a gasket at the other end of the inlet, where it goes into the cylinder head? Could be air getting in from there weakening the mixture too much?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 04, 2016, 06:40:24 PM
Yeah, there's a thick composite gasket at the carb end & a thinner one at the cylinder head end I think Clive -it was a long time ago that I fitted the manifolds. I can check if they're leaking , but pretty sure they're sealed.
Suffered a savage kickback at one point, which really bruised the muscle in my thigh, so I'm limping slightly now! When I was younger, this would be the point where I'd spend days fighting it, before giving up & selling it for a fraction of what it's cost me. Now I'll keep calm & persevere. It's curable, but I need advice on just what needs curing. I'm on holiday this week & have decided to take a day off tomorrow & enjoy the sunshine -taking the oft' repeated advice to walk away from it for a little while.
On the plus side, when it runs, it sounds like an old Brit twin -which is more or less what it is, (the XS was originally a BSA design). The pipes are loudish, but not excessive, (XS ive?). No nasty mechanical noises so hopefully all's well engine wise. Each time it's started, it's done so fairly easily -no Harley style, massive lunge on the kickstart required. Hopefully, once the carburation's sorted out -if that's what the problem is -it should be a nice, blat around the country lanes on sunny days type machine.

Any thoughts or suggestions?

Fuzzy photos, just to prove Nathan's wiring works. The lights are wired so that the side light & tail light are on all the time because I haven't got an on/off switch on the bars, just a high/low beam one. There are two key positions, the first is ignition + sidelight, then ignition + low beam. This is low beam. Indicators are LEDs & seem to flash at the right speed, (when bulbs are replaced with LEDs they often flash too fast, but can be fixed by fitting inline resistors). You can see the LED number plate light under the lip of the mudguard here as well. Horn works fine too but no photo of that  :)

I'll probably get laughed at Andy, but ! do you own a blowlamp? warm up the engine gently, warm up the plugs 'til hot (ouch) screw them in and try, often once running they settle down. Bit of a set back, if it was easy you'd lose interest  :D

Title: Re: Manky's XS650 Yamaha
Post by: Dslam on May 04, 2016, 07:51:01 PM
OK We have ign timed, compression and it fires when flooded or fuel poured into the combustion chamber. This would imply not enough fuel. You may have a pilot jet blockage (bit of a bugger on these carbs) or too much fuel. Sounds counter intuitive but try flooding the carbs, no choke, open throttle wide and kick. When it fires it will either rev up or die. If it revs up it's pilot or float height. If it pops and farts then dies you have more of a blockage than you think. Either way you are on the cusp of infernal combustion.

Reminds me of whewn my mate Bob was trying to get my Maestro started after it had stood in a garage foir 2 years without being touched (bearing in mind I know nothing about the XS) - the problem with the Maestro turned out to be the seal in the petrol pump had dried out, after squirting fuel direct into the carbs several times it ran for a little while - then a little while longer - and finally it kept running!

Running like a bag of nails but as Bob said, it's easy to sort that as long as it's actually running!

What about the carb rubbers - are they dry and letting air in?  I remember reading about how to cure that but as I'm an old bint, I don't remember what it was I read!


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 04, 2016, 08:44:35 PM
No carb rubbers fitted Bobbi. I've swapped the original Japanese Mikuni carbs for old British Amals, basically cos they look cool. Hence the self inflicted problem comment. There's a guy on Ebay who sells cast aluminium manifolds to fit Amals to XSs. Goes by the name of Greensand Foundry if you're interested. I've got a pair of those & set the carb jets & needles up the same as his bike -I did wonder if I contacted him he'd say That's funny, mine doesn't run either!
Valves haven't been touched since I bought the bike. Everything I've looked at seems to be in good condition, so it's either a low mileage engine, or been looked after. So I'm assuming they're O.K
I'm not allowed to play with fire. Or crayons.
Current status:
kick, kick, kick, fiddle with the tickler buttons, tweak the mixture screws & eventually it'll fire, but die after a few seconds. Trying to catch it by blipping the throttle, it just goes bleurgh, bleurgh, bleurgh & still dies. Feels like no fuel.
No chokes fitted.
So no point lifting the needles yet then? Lots of fuel, full throttle, kick?
I may try hitting it with a stick eventually.

Andy , go back to basics with the carbs .

{ 1 } Do you have Viton tipped needles in the floatbowl chambers ?
If not , it is worthwhile changing them as it helps towards alleviating vibration bounce . 

{ 2 } Check the float height as per ;
http://amalcarb.co.uk/optimising-mark-1-concentric-fuel-levels 

{ 3 } Check that the needles , jets ,  slides are the same as per ;
http://amalcarb.co.uk/rebuilding-mark-1-concentric-carburetter

{ 4 }  Since you have removed the chokes have you blanked off the the top ?

{ 5 } Did you use a couple of lollipop sticks , nails , biro pen inserts  , etc to check that the slides were opening at the same time ?



Title: Re: Manky's XS650 Yamaha
Post by: Olds on May 05, 2016, 06:10:27 AM
Fifer mentioning viton tipped float needle, made me remember that there can be problems using the brass bodied ones as they are heavy and can cause erratic fuel level height, aluminium ones are available from Burlen.
You mentioned in line filters. Are these in addition to the in bowl filters ? Shouldn't cause a problem though.
You could try restricting the bellmouths to see if choke will be needed.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 05, 2016, 08:07:20 AM
Yes to most of your list Fifer.
Brass needles with black tips. The problem was flooding of the float bowls rather than not enough fuel in the bowl.
Floats are plastic so I can't bend the tab that holds the needle, to alter the float height, cos it'd break. Checked the Amal site & it says that type are non adjustable.
Needles, jets etc are as per the guy I bought the manifolds from. Work on his bike so should at least run on mine.
Aftermarket cast aluminium carb tops with no choke fittings.
Yes, slides synchronised using lolly sticks under them, (easier to see movement in the sticks than just the slides).
Yup, 2 filters to each carb.

Maybe this can be the challenge at the Basingstoke show at the weekend -see who can get it running :)

Post by: morrag on May 05, 2016, 03:48:51 PM
Andy, provided the valve timing has not been interfered woith, we can assume its ok. Similarly, if your ignition timing is set to fire marginally before TDC then it should fire the fuel, even if not ideally and accurately set. Now, fueling, if you inject fuel in to each cylinder, then install a pair of clean, "warm" plugs. it should run until that ful is used, so.... if the motor has been standing the rings might be gummed up, leading to low compression and lack of "suck", so do a compression check, you should see over 150psi, if not bung a mixture of WD & a touch of diesel into each cylinder, let it soak for a day, blow it out with the kickstart, then, inject fuel and....it will run, got to! once thats achieved, set the carbs up, ie. 1 1/2 turns out from closed for your needle valves, throttle abutments to touch slides, plus a whisker! stop the float chambers flooding, and Bingo!........ ;D ;D ;D ;D

Just had a "manky moment" my dolomite sprint was reluctant to start, choke cable came adrift, reconnected it and fired up first time ! So you have no choke, gaffer tape across the inlets and poke a pencil size hole through it. Rich mixture by less air equals a choke, what have you (we) got to lose. Hope it works, really hope it works.


Title: Re: Manky's XS650 Yamaha
Post by: morrag on May 05, 2016, 06:34:10 PM
Maybe not "simples", but check each cylinders compression, please. Re choke, the "ticklers" are there to enrichen the mixture at starting, so you shouldn't really need chokes, honest, but partially blocking the inlets won't do it no harm, however you have timed the ignition on the firing stroke, haven't you? just a thought ;)...Morrag

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 09, 2016, 09:19:35 PM
I'd like to point out I had actually had it running last week, but only for a few seconds at a time.  :)
Definitely not right, but yes, there is life. Chris, (one of the regulars at Loony's workshop & "forgotten" here on the forum), was determined to have it going & as he's 30 years younger than me, I was quite happy to let him kickstart it for 10 minutes in the blazing heat at the transport show yesterday. His Dad's an ex side car racer so tweaked the Amal carbs a little. It's running far too weak, as we said, so he just wound the mixture up a bit. I think he also cupped his hands over the air filters too to reduce the amount of airflow. Lots of throttle & lots of kicking & it did indeed fire up & very nearly tick over. Vibrated a fair bit but it was being revved quite hard at the time. As I said the other day, it probably needs the needles lifted from the centre position to the top one & maybe bigger jets -which is where Mr Dslam's superior expertise will come in. I don't want a race tuned engine, but I'm hoping it'll be as well behaved as a standard XS650 -if it's too highly strung & temperamental it'll just be hard work to ride. Hopefully Andy can tame it on Wednesday.
Burlen Fuel Systems, who still make Amal carbs, as well as SUs, are based in Salisbury, not far from here, so if I finish work early enough tomorrow, I may nip over & buy a pair of the later model "Stay Up" floats, which are adjustable, unlike the plastic ones my carbs have. I'll see if I can buy the next size up jets too.  
Got lots of attention at the show yesterday, as did all the other Manky vehicles on our pitch. Only small low spot was finding as we were about to load the bikes back in the van at the end of the day, that someone apparently took a liking to my bar-end mirror. It's possible it was dislodged during Chris's kickstarting, but it was pretty securely bolted into the end of the bars. Looked like someone had had a very determined yank at it & managed to get it halfway out of the bar. Still got it & it's not damaged so no real problem -just one of the joys of public shows.
Standing back & looking around the bike in the sunshine, I'm very happy with it. I suspect the plastic indicators will fall apart at the first sign of vibration & you can see all the joints in the chromed exhausts, where I welded the various sections together then ground them down flat, so I wouldn't be surprised if they fracture at some point. If so, I'll replace them with single piece polished stainless ones. Otherwise, I'm hoping it'll stay very much as it is for many years to come.

They were just quirky & unusual -& cheap, (about 2 quid for a set of 4 from Malaysia, including postage). They're only held with a bolt into a plastic body, so will either fall apart or fall off. I might try brush painting them with liquid superglue or something to try & seal them together & to the bike. It amused me to run the front brake hose through the hole in the middle of one & bolt the rear reflector into another. The exhaust blows through the hole in the other rear one.
If we can get it starting easily & running smoothly I'll be very happy.

Andy , I know you said that the jets were as fitted to another XS and gave them as


Quote
For those that like to know these things, these are the carb details:

MK1 AMAL 930 concentrics

Throttle Valve #3 1/2. ( Part No~40-928060/3.5 )

Main Jet #140.( Part No~40-376100/140 )

Needle Jet #106.( Part No~40-622122/106 )

Throttle Needle

(2 Indent) ( Part No~40-622124 )

The needle position is set to the 2nd groove down, (midway).


On all the many Bonnie motors I have owned , the Main jets { with standard settings and choke slides fitted } were always between 180 and 220 .
I always removed the choke slides and blanked off the carb tops and , depending on what spec of tune I had applied to the motor , upped the main jets to suit .

Standard Bonnie motors were fitted with either a #2  1/2 or a #3 slide cutaway
A smaller slide cutaway will really richen it , as will lifting the needle position

Throttle Slides

Throttles Slides are stamped with their identifying size on the bottom surface. Typical markings will be either 622 for a 600 Series slide, 928 for a 900 Series slide, an MB number which is a foundry mark, and a stamped number from 2 to 5 indicating the height of the cutaway on the inlet side of the slide.

The angled cutaway on the slide manages the transition from the pilot circuit to the needle jet when the bike is running. Smaller cutaways will richen the mixture, larger cutaways weaken it.

I only had to tickle the carbs till the petrol flooded out of the plungers and { set up correctly } one kick and they would start with only the tiniest bit of throttle from cold .

Hiya. I showed my scrap of paper with my jet sizes on to the guy in Burlen's this afternoon & asked what he recommended. He said what I had should be more or less right. I think the pilot jets are fixed in my carbs & can't be changed & the main jets will affect top end running, rather than starting & tick over, which we're looking at at the moment. 3 1/2 throttle slides are also roughly right I'm told. It's more than 30 years since I last played with Amal carbs & I have trouble remembering what I did this morning, so I'm happy to take advice. We'll see how we get on tomorrow.


Title: Re: Manky's XS650 Yamaha
Post by: Olds on May 11, 2016, 05:37:12 AM
You are correct about the pilot jet being fixed. It's a very small diameter hole in a piece of brass and tends to get blocked and suffer from lacquering.  It may be that with use, the fresh fuel will help remove any restrictions as might compressed air, (or air in a can) but pumping some carb cleaner through it, may speed up the process. Sometimes though it may have to be cleared with a piece of wire. The high e string from a guitar can be used 0.010" to 0.015".
You need to throw these new fangled concentrics away and fit some proper 376 monoblocks. :D
Good luck with this today.

Mr. M, it really is worthwhile checking your cylinder pressure, honestly, takes no time to do, and if nothing else can then be rules out, after all by your own admission it's been standing a spell. You have a relatively short stoke motor, which may not be developing sufficient "suck" to get sufficient fuel in, should pumping pressure be low. Over the years I have used all types of Amal carbs. and although sometimes evident, have seldom required choke slides to start an engine, maybe in the depths of winter!. The "tickler" gives you all the extra richness required for start up. Forget the main jet at this stage, and the throttle cut away is adequate, the fixed pilot must of course be clear, as per Olds advice,needle valve 11/2-21/2 out and........ ;D ;D ;D ;D, just got to.....

We do indeed have life. Many, many thanks to Mssrs Dslam & Oily Bike for their time today, (& the cake). I realise how frustrating it must be trying to explain the finer points of carburation to a 4 year old, but I appreciate them trying!
Hopefully Andy, (Dslam), will run through the details cos I know I'll get them wrong, but it's now firing first kick & ticking over, though fluffing a bit on blipping the throttle.
All sorts of muck in the float bowls & one fuel tap partly blocked by crud from the bottom of the tank didn't help, (now cleared with an air line & the small foam inline filters replaced with larger paper element ones).
Blowing exhaust at the head produced a bit of popping & banging but now hopefully fixed.
Compression test showed 6 1/2 bar on both cylinders.
I've left the bike at Andy's place for now, so he can have a think about it & fine tune it/poke it with a stick, but it's very nearly a fully functioning motorcycle now. Thanks again chaps.  ;)

After a whole afternoon of tweaking mixture & throttle stop screws, lifting, (& lowering again), the needles etc, I've completely lost track of just where we are with it -hah! "We" -as if I had anything to do with it. I sat on a stool in the corner of the shed & tried not to break anything.
As I said to Mr Slam, this is my "keeper" bike. I'm not building another, so it needs to be reliable & useable. So he has a free hand to modify or change whatever he thinks it needs. Looking forward to road testing time now.  8)

Already insured, so I guess I could book an MOT on the way home from Andy's house.
It was taxed as "disabled" by the previous owner, but hopefully that's just a matter of ticking the appropriate box when I re tax it.

Post by: Dslam on May 11, 2016, 10:03:35 PM
As Andy said,
Loads of snot in the bowls and the small fuel filters fitted would struggle to pass enough fuel without the addition of grinding grit and paint residue blocking them further.
First job-float height. I know from experience this is often overlooked. Although the height is not critical they need to be the same. This done I realised that the carbs are from different periods. The left one has the screw in pilot jet and the right has the pressed in variety. Both are pre Burlen.
Dumped both stripped carbs into the ultrasonic cleaner for 20mins on jolly hot setting. The fluid began clear and ended up a rather nasty grey colour.
Balanced the slide lift by eye.
Rebuilt and fitted we attempted a start. Fired up but ran as rough as hell. Out with the screw driver and start twiddling in an attempt to get a clean idle. This was followed by soft blip and hard blip which revealed over rich transition from pilot to slide cutaway. The next size up would probably make it too lean so I plan to mill the slides to suit. I have successfully done this in the past.
A few small oil weeps and the left exhaust  blowing at the head. Dragging clutch are all minor issues.
I will concentrate on the running issues as Andy is more than capable of sorting those issues.
So, thus far we have a runner. Ticks over OK but not good enough. Rough pilot to slide transition. Needle transition seems OK. Cannot really test needle to main until we get it on the road.
After a few chores tomorrow morning I shall continue.................

Congratulations, once its run for a spell you should expect more like 120-130 psi, thems "Christian units Andy!, per cylinder with no more than a 10psi dfference between.Usually, once going the tweaking settles them down and....bingo, where's that open road.................Morrag


Title: Re: Manky's XS650 Yamaha
Post by: Dslam on May 11, 2016, 10:12:16 PM
I was concerned about the 6.5 bar reading, sorry 91psi. Quite low but both pots the same pressure. It is either my pressure gauge is tired or the rings need a bit of running to seal it or strip and rebuild (hopefully not!!) It revs quite crisp on the needle jet and sounds good too so I think all will be well. We shall see.


Title: Re: Manky's XS650 Yamaha
Post by: Olds on May 12, 2016, 04:23:12 AM
Well done sir. Hopefully decent filters will stop most of the gunk still in the tank from reaching the carbs. The fact that both cylinders  are low on compression but the same, at least suggests nothing is disasterously wrong.

Post by: Dslam on May 14, 2016, 09:17:19 AM
The saga continues...............
Spent some time on the carbs again yesterday and was struggling to work out why I couldn't get the two cylinders to balance throughout the rev range so I went back to basics.
Rechecked timing OK
Rechecked tappet clearances OK
Rechecked compression. Improving and balanced on both cylinders and not leaking down.
Conclusion. Must be carbs.
Removed them both and stripped down and started comparing the two. We know they are odd because one has a screw in pilot and one has a pressed in jet and both are pre Burlen. Did some research and found the pressed in type has a 20 pilot and the screw in is 25. Hmm, thought I, that ain't helping.
Then I noticed that the needles were slightly different. One has a shallower taper than the other and the end is subbed. The other is steeper tapered and point ended and the taper begins earlier and to add insult to injury, the needle jet is lower in the body than the other as well. It looks like someone in the past has, unsuccessfully, tried to balance the two by playing with the needles. I then realised that the needles were slightly different lengths too which made the clip slots at different heights. Ruddy Norah I am really in a hole now!!
The exhaust on the left side was blowing at the head which I tried to resolve but it seems that the flange (love that word) is cracking away from the pipe where polishing prior to chroming has thinned the weld to paper thin and the pipe itself is bearing on the clutch cover forcing it up, stressing the flange (that word again) allowing gasses to pass. Poo thought I. (feel free to insert suitable expletive!)
Nothing for it. New carbs. Andy wants a useable and reliable motor as do we all but unfortunately these carbs are not going to provide it.
Had a conversation with Lord Monkey and new carbs will be procured and the exhausts remade in stainless by Andy's Brother. An expert in the field (no pun intended) of pipe fabrication then back to Ches Dslam for the final tune up.
All in all a wallet numbing experience but I hope the end result will be worth all the effort and that his Mankyness will feel the same.

Nothing that can't be fixed &, as Mr 'Slam said, I intend to keep this one for a very long time, so may as well get it right. I trust his judgement & did ask him to do whatever he thought was necessary, so if he says new carbs, it gets new carbs. No point trying to bodge it cos I'll be the one who has to live with the bodge.
Definitely no more projects. Ever.

Dave, I haven't got the original carbs any more, or the inlet rubbers. Yeah, I could weld up the existing pipes for now, but like my truck, I don't want to run it bodged up -I want it properly sorted. Just going to take a bit longer than I'd hoped.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 16, 2016, 10:37:41 PM
Many thanks to Mr 'Slam for returning the "Frog" to Basingstoke this evening.
I was tempted to chuck it in the garage, lock the door & never return, but I've had time to reflect & will persevere. I've always said it'll be my last bike build, so if it takes a little longer to get it right, it'll be worth it.
So, first job will be to phone Burlen Fuels in Salisbury & order a pair of carbs, fitted with the jets, slides & needles as listed by Andy after consulting with several of his classic bike colleagues.
Then I'll ring Armours in Bournemouth. They make exhausts for classic bikes. The exhaust note's a little ...harsh. Ideally I'd like it no louder than a standard XS but we'll never achieve that. Not so much the volume, more the pitch. I'd like to soften it a bit & Mr Dslam agrees. He suggests a pair of short Triumph Tiger Cub trials silencers. If I can find a pair in stainless & they're physically small enough, I'll fit them halfway along the pipes, more or less where the heatshield is. That'll still leave the long parallel tail pipes, which I really like. I'm going to have to grovel to my brother Steve, of FieldCraft Fabrications -again, & ask him to copy the pipes in stainless, with larger flanges at the head. It's what I should've done to start with. 
I've also got to take the tank off, drain the fuel & take it over to BKI Welding in Newbury, Berks. They've welded many a fuel tank for me in the past. There's a breather pipe inside the neck of the tank which exits underneath. I didn't want a pipe stub sticking out the bottom of the tank & it's only a breather, so I cut it off flush with the underside. The petrol fumes have got under the edge of the paint though & blistered it. So I'll get a 90 degree stub welded back on so I can attach a breather pipe, running back tight to the underside of the tank. Another self inflicted problem.
Mr Coppersmith's very kindly shortened an old speedo cable for me, (from Loony's Speed Triple), so I can fit that & also connect up the illumination for the new, smaller speedo.
The clutch is dragging, but I'm not entirely sure why. Not just adjustment. I fitted new plates & it's got a new lever & cable. The original Yamaha pushrod, which pushes the plates apart, is in 2 pieces with a ball bearing between the 2. YamBits sell a one piece upgrade, so I might start with that. The only other parts are the worm drive that connects the cable to the pushrod & the springs in the clutch basket.
So, biggest job will be remaking the 'zorsts. Hopefully Steve can do that, partly cos it'd be nice to keep it in the family, but also cos he's bloomin' good at what he does. Once that lot's done, it'll be back to Dslam for another tune up.

New carburettors ordered & paid for over the phone for collection on my day off later this week. They didn't have any "empty" carb bodies of the right size in stock, but had a pair already made up to suit a BSA Lightning, which they can re-jet to suit. That's the best part of a week's wages gone.  :-\


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 18, 2016, 05:48:56 PM
Tank back off & drained, ready to take to the welders tomorrow.
Been thinking about the exhausts. I've got a pair of 2" bore stainless "Cherry Bomb" silencers in the lock-up, waiting to go on my truck. Obviously far too big, but if I could find a smaller version of these, they wouldn't look too bad. The heatshield on the top pipe's 16" long. If I could find something 1 1/2" bore, 12" long & as small a diameter as possible, it might work.
Before you shout at me for ruining the lines of the bike, I don't want anything too obtrusive & if I can't do it tidily I'll just get the pipes re-made as they are. I'd like to make the exhaust note a little more civilised if I can though. Not into loud pipes, whether they save lives or not.  :) The Pop exhaust uses 4 silencers, (2 each side), which gives it a pleasant burble. I'd like the bike to be the same, but will settle for reasonably sensible.

That sky looks a bit iffy.

Mr Dslam has a mate who's a bit of an XS expert -he reckons they don't like running 2 into 1 systems. To get them tight together, one above the other, I'd probably have to cut a slice out of the length of each then weld a flat plate between them, so they're welded together, but still 2 separate pipes.

My day off today so this morning I drove to Newbury in Berkshire to drop the fuel tank at the welders. It needs a right angled extension to the breather pipe underneath so I can run a rubber pipe along under the tank & tucked down the back of the cylinder head somewhere. Not entirely sure the guy understood what I wanted, but we'll see. My own fault cos I cut the vertical breather pipe stub off, flush with the underside of the tank, thinking it's only a breather, that'll be fine, but the fuel fumes have blistered the paint. Yeah, I'm stoopid.
While I was in Newbury I collected a pile of powder-coated parts for Mr Loon -the shotblasters/coaters are in the same road as the welders. They're a heavy duty, industrial company really, (they originally set up to blast & coat pipeline fittings for North Sea oil rigs). So they always have interesting stuff in the workshop. A 24 hour LeMans Jaguar chassis for example.

Strangely enough, neither have I.  :)
Then on, down to Christchurch in Dorset to look at exhaust silencers in Brit Bits. Unfortunately I arrived at 3 in the afternoon & they shut at 1. Every day. And only open on Wednesday, Thursday, Friday & Saturday. How do they sell anything?
So I tried Sammy Miller's trials bike products in the New Forest. Couldn't find it. Neither could the Sat Nav on my phone, (it's supposedly 2 roads from the Sammy Miller Museum).
How about Armours exhaust manufacturers in Bournemouth -nope. They don't have a shop & only accept visitors by appointment.
So I went home.

Loony mentioned this afternoon that he knows someone who works for a local performance car exhaust place, who might be able to bend the new pipes up for me at work. So I've taken the old ones off the bike & will see what can be done. Still looking at push-in baffles. These look more promising than most, but are about 20 quid each. I'd have to adapt them to fit my 1 3/8" pipes, (1 1/2" O.D), & I'm guessing from the photo that they're probably 6" long cos they're 1 3/4" diameter, so I'd have to buy a couple for each pipe.
My memory really is appalling -I thought the existing baffles were around 8" long, but when I pulled them out, they're actually 16" (2 8" ones welded together) -& still too loud.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 20, 2016, 05:52:59 PM
Also took the carbs off. I'm just about to nip over to Mr Dslam's lair in Surrey to drop the old & new ones off to him. Not sure if the hose fittings & Carb tops with their screw in cable ferrules, need to be swapped over onto the new ones. Mr Slam has a stall at the Kempton autojumble tomorrow morning, so might be able to sell the old ones for me.
These have also arrived in the post from the States today. CNC machined brass twiddlers for the mixture & tickover, to replace the standard slotted screws. Utterly pointless & will probably get twiddled by every passing show goer, but I just liked 'em. I'm pretty sure Mr 'Slam won't.

Bloke who used to lodge with us had a V-Max with a Kerker silencer a bit like the one below that was REALLY loud - someone suggested he shorten the silencer by almost half - he did, and amazingly, it was a lot quieter!

going back to the baffles..  if it's too loud then can't you just wrap them in a little fibreglass wadding to give more muffle?

Re baffles. If I remember correctly, the type of baffles you have,  can make the exhaust note harsher.
It's not difficult to make straight through glass wrapped resonator tubes, but you really need to use perforated core tubing rather than wrapping around these louvred baffles. Though I'm not sure where you will find 3/4" perforated tube. Perforated sheet is easy to get hold of so rolling your own wouldn't be hard.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 20, 2016, 09:18:26 PM
Yeah, Andy, (Dslam), pointed out this evening that it really needs a silencer to provide some resonance to alter the tone & make it deeper. I think I'll get new pipes made up from a single length of stainless, which will solve the current problem of the pipe fracturing where I've welded several pre-formed bends together then sanded the welds down flush. Then I can experiment with baffling & if that doesn't work, I can splice a pair of silencers into the middle of the new pipes.
These would work & are about as small diameter as I'm likely to find, but I appreciate the square cut ends might not look pretty -but then, they might suit the long straight pipes? I'd have to cut a slice out of their length & weld the 2 together with a flat plate between them to get the inlets & outlets close enough together, so they'd be a single piece but separate silencers inside. Not sure what that would do to the resonance.

Stainless as a silencer is bad news, it will tend to produce a "tinny" note. Its not unusual to use a MS box wrapped in stainless. Those plug in baffles are both restrictive and poor silencers.

As Sir Manky is looking at his XS650's zort system, and the noise it makes etc, thought I'd throw a few pics of high level pipes just to help get the design juices flowing.

Although these are flat-tracker style bikes, the above-engine-case systems with silencers give a bit of an idea of what's possible.

Have seen and heard the 'stubby' on a Triumph twin, and then heard the same bike when replaced with the slash-cut, and in my opinion (and the owner's too), the slash cut was waaaaay better.

Just out of interest, one of the most 'tunable' silencers around are those made by the American company Supertrapp where there are a selection of end baffles/discs that can be added.

Don't forget when you're on it, it won't be so loud as they exit behind you.

It's just the rest of us that will have to deal with it.

Well that was an expensive week.

Pair of new Amal carbs £295
New clutch components, (worm drive, pushrod & springs, plus a couple of other bits & pieces while I was ordering from xs650shop.de in Germany), £115
New polished stainless exhaust pipes, £240

My brother recommended a performance exhaust company near Salisbury in Wiltshire that he's used a couple of times. So I visited them this afternoon. "Torque Technique". Very helpful guy. He can't match the radius of the righthand pipe because I made it from sections cut from 2 different pre formed bends, but he can get close by stepping the tube diameter up a size from 1 1/2" outside diameter to 1 5/8". Hopefully I can do something with that. They'll need flanges, (big washers), welding to the ends to fit into the cylinder head ports. Didn't occur to me till I was on my way home that the finned exhaust collars might not fit the bigger pipes, but if not, I'm sure they can be modified. Once I've got the pipes to play with I can see just how much room I have for silencers, but will try them first without, just in case they're actually quieter than the old baffled ones. Should be ready next week.
Also visited the welding shop in Berkshire who have the fuel tank. They're welding a breather pipe to the underside to replace the one I stupidly trimmed back flush, (the fuel fumes blistered the paint around the breather hole so it needs a pipe that I can fit a rubber hose to). They didn't have any suitable steel pipe so I picked up a length from B & Q, rolled a 90 degree bend in it & took it over to them. The old breather pipe is brazed into the bottom of the tank, so they can't weld to it. They said they'd try soldering instead.

I reckon the total cost of this build, including the original donor bike, is now somewhere around 2 grand, plus a grand's worth of engraving. So I need to keep it for about 10 years before it becomes a sensible investment!  :P

New clutch wormdrive, (connects the cable to the pushrod), new pushrod & new springs. Now I need to drain the oil, remove both side cases & fit it all. If that lot doesn't fix the dragging clutch, nothing will -no, it's not just cable adjustment.  :)
Also bought new wheel spindles cos both of mine are pretty battered, & new exhaust gaskets.

Also nipped over to Torque Technique in Salisbury, Wiltshire after work this afternoon & collected the new stainless exhaust pipes. Haven't tried them on the bike yet cos I was still in my Post Office uniform & didn't want to get too grubby, but they look like a pretty good match for the old ones. 220 quid cash.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 01, 2016, 09:17:03 PM
The old ones were 1 1/2" O/D, but they couldn't match the bends in that size cos I'd made them from 2 different pieces welded together so that the radius changed half way round the curve. So the new ones are 1 5/8". Fortunately the finned exhaust clamps still fit. I need to find some stainless washers the same size as the ports now to make flanges.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 01, 2016, 09:20:34 PM
I mentioned baffles & they said they make cone shaped ones from perforated stainless tube. About 6" long, with the small end about 3/8" & the large end the diameter of the pipe. They don't quieten pipes fully but do change the pitch. Might be worth experimenting with. They gave me an offcut of perforated tube to try.

Precisely.
Nipped over to Berkshire after work this afternoon & collected the fuel tanks from the welder. I took mine over to have a new breather pipe welded to the underside. So while I was going, Tom gave me his to take as well cos it was leaking.
Turned out his was leaking in 3 places, not the 1 he thought. Fixed with a mix of welding & silver soldering.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 02, 2016, 07:58:49 PM
I supplied a length of 6mm bore steel tube, which I'd rolled a 90 degree bend in, to replace the original breather pipe, which I'd stupidly cut off flush with the underside of the tank. It pointed straight down & would've looked 'orrible with a breather pipe on it cos the tank sits quite high. Unfortunately, as soon as we put fuel in the tank, the fumes lifted the edge of the paint around the hole.
So BKI Welding in Newbury, Berkshire silver soldered the new pipe over the old hole -they couldn't weld it cos the original joint is brazed. It now points back down the tank, so the breather pipe will run along under the tank & drop down the back of the engine. Should've done this to start with, but didn't think it through, obviously. Now the tank will need cleaning up & repainting.
Both tanks sorted for 25 quid cash, so £17.50 each.

Hi Andy- Re the clutch on your bike.
Not sure which engine/clutch/combination you have (‘earlier’ Vs ‘later’), but I had a look through a couple of Haynes Manuals for the XS650s.
One is the 'original'  "1970 on" and has a pic of a spoked-wheel Roadster, the other is the "1970 to 1993" with a pic of the red Special/US Custom with chapter 7 devoted to the 1977 to 1983 models.
Just in case you (or fellow Monkeys with XS650’s) weren’t aware, there’s some interesting clutch info:

"1970 to 1993” manual: In chapter 7 (page 139), the specification for the number of Friction Plates says - "7 early models, 6 later models" ("1970 on" original manual confirms), and number of Clutch Plates - "6 early models, 5 later models",

Page 147, section 4, gives details of the Clutch Modifications for various models (primarily the method of securing the clutch nut to the mainshaft, and that a shock-absorber assembly is fitted to certain later models).

http://www.xs650.com/tech.php
http://www.xs650.com/forum/showthread.php?t=143     may have some interesting reading............  ::)

Hope you have success with the clutch rebuild……………  ;)

Mine's an SE, but I don't remember any shock absorber assembly. Interesting that it says not to mix the inner steel plate with any of the others. Why? Is it thicker? Wouldn't make a difference to the operation surely?
So mine should have 6 friction plates & 5 plain. It'll probably be one afternoon next week before I get a chance to work on it, but I'll count them then.

Mine's an SE, but I don't remember any shock absorber assembly. Interesting that it says not to mix the inner steel plate with any of the others. Why? Is it thicker? Wouldn't make a difference to the operation surely?
So mine should have 6 friction plates & 5 plain. It'll probably be one afternoon next week before I get a chance to work on it, but I'll count them then.

Sorry, don't know the answer to the first question........

If yours is the later SE clutch (assuming no-one swopped clutches before you got hold of the motor), yep, 6 & 5.
The shock-absorber part of the clutch basically takes up the space the 'additional' Friction & Plain would have occupied, and comprises of a 'conical spring' and 'spring seat' (these sit behind the last Plain plate when you take all the plates out, and are of similar size).

Made a pair of baffles for the new pipes this afternoon. The guy who bent the tubing gave me an offcut of perforated stainless tube, long enough to make two 12" ballaffles.  :)
They have a 2" parallel sided collar at the back end, which I'll weld a stainless M6 nut into, then drill a hole in the pipe & bolt them in. At the front end they're cone shaped, tapering down to 3/8". Mr Loon has some fibreglass exhaust wadding, so when I fit them, I'll loosely wrap a length around the cone, secured with stainless welding wire. Hopefully that'll knock the harshness off the exhaust note. They're not particularly pretty, because I made 'em, but nobody will see them.

^^ WHS

Put as much as you think you'll need, then take half out.

Conical shape is good, gives different lengths to "baffle" the waves of compressed exhaust gas.  It'll work a treat chap.  Went through a similar process on the just sold trike.

Post by: Olds on June 05, 2016, 10:16:45 AM
Err. Could easily be wrong, but I thought you shouldn't wrap conical baffles if fitted that way around, due to the wrap compressing onto the perforations, causing an increase in backpressure.
Think I would try it as is, perhaps held in place with mole grips before drilling the new exhaust pipes. You may also wish to try to vary the distance the baffles are from the end as this might (or not) change the note of the exhaust as well as making them less visible if mounted further in


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 05, 2016, 10:31:51 AM
Yeah, I was going to put them about 6" into the pipe end, so they can't be seen. O.K, no wadding first then.

Captive nuts welded into the baffles & the damaged paint on the tank rubbed back, ready for Mr Loon to spray in 2 pack high build primer.
I'd really like to ride this to the Nostalgia Nationals drag races at Shakespeare County Raceway in Stratford on Avon, which gives me just a couple of weeks to get the tank done, exhausts done & the clutch rebuilt, plus the new carbs fitted & tuned. Oh & an MOT & tax. Easy.  :P

5 hours spent on the clutch this afternoon & I'm just about ready to beat the cr*p out of the thing with a hammer.
New worm drive fitted.
https://www.youtube.com/watch?v=N8EJ4oBWNe8

New pushrod fitted -it's a new style, one piece one instead of the old 2 piece with ball bearing in between type. Might not look it in this photo but they're exactly the same length.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 11, 2016, 07:53:34 PM
New clutch plates already fitted, but I took them out again & checked them. All look O.K -a little black gunge in the oil in the clutch basket, but it looks like fibre dust from the friction plates mixed with the oil. 5 steel plates & 6 friction ones as previously stated. There's also another steel plate which sits against the back of the basket & I wasn't sure if that should be one of the 5 steels. Tom's got my Haynes manual, but I checked a couple of YouTube how-to videos, (the wonder of Smart Phones), & I'm pretty sure it's 5 plus that one. If it wasn't, the first friction plate would sit directly against the inside face of the basket.

Opened the box of new clutch springs & ...poo. They ain't right. Nothing like the originals & what are those 3 screws for? The springs are far too short & don't even fit onto the shaft of the screws. So back to the old ones.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 11, 2016, 08:10:13 PM
With the clutch basket cover on & the old springs refitted, I hooked up the cable to the worm drive.
Still not right. With everything adjusted as far as possible, the plates move maybe 3mm when the lever's pulled right in to the bars. Looking at this video, that seems to be about all this guy's move:
https://www.youtube.com/watch?v=4oYFW1rycKU
But it's not enough to disengage the drive -when I put the bike in gear & rock it back & forth, it's not releasing. That's with the adjusting screw on the worm drive screwed in until there's no free play & the cable adjusters at both ends on their maximum setting.
Really don't know what to do now, although hitting it with a hammer's a tempting option. Maybe the friction plates are too thick? Maybe they need really soaking in oil so they slip more? Maybe there's not enough travel in the new worm drive to move the pushrod & push the plates apart?
With the lever pulled in, I can push a screw driver, (carefully), between the plates, so they are separating, but apparently not enough. Shouldn't have to have everything on it's maximum adjustment either.
I'd planned to get most of the jobs done this afternoon, but fell at the first hurdle.
I'll go back to the garage in the morning, with a fresh eye & see if I've missed anything. I'll have another look at the worm drive to check it's moving freely & maybe try the old one again. Maybe the plates just need some use to bed in & wear down a little, but it stalls when you try to change gear, so isn't rideable as it is.
Any suggestions before I fetch my hammer?

Are you using the standard clutch lever or at least one with the same amount of cable movement ?

Aah, yes. Of course you're both right. Thanks. They'll be in the spares pile for future use then.
It's a pattern lever Dave, bought from YamBits, so ought to be right.
Woke up to rain this morning, which is refreshing after the heat of the last week, but means I can't work outside till it stops, so can't work on either my bike or my truck.
So- clutch basket assembly all looks good, spring bolts are tightened down correctly, pushrod moves freely, new lever is pulling the new cable correctly as far as I know. I'm guessing the worm drive mechanism isn't sitting at the right angle, so that it runs out of travel as it winds out. I'll take a look at that first later. May need to use the operating arm from the old one on the base of the new one. Nothing's ever easy is it.  :(

I've had that problem with the worm drive thingy on my GT when refitting the cover.  Do it the same every time, sometimes it works, sometimes it doesn't.  No idea if yours is anything like mine of course, but you seem to have to have it in a certain position - no idea what that position is though.  Very frustrating.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 12, 2016, 08:48:09 PM
Certainly is Bobbi.
Well I took the lefthand cover off again & checked the worm drive. New one installed, compared to the old one.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 12, 2016, 08:52:56 PM
You can see that the new one has 2 clevis holes. I've tried the cable fitting in both.
The outermost hole effectively makes the arm longer, which makes the clutch lever feel softer, but gives less clutch plate movement for the amount of lever travel.
The inner hole makes the arm shorter, so a stiffer lever but it pushes the pushrod further, so separating the clutch plates more.
I decided to go with the inner hole, which is in the same as the old worm drive.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 12, 2016, 09:06:22 PM
The old worm drive has a damaged mounting cos it's made of plastic & has gone brittle with age. The new one's a mix of plastic & metal. I've tried using the old drive in the new housing, but the threads don't seem to be quite the same & I didn't want to force it.
Had to drain the oil to remove the righthand cover to check the clutch plates. I also removed the sump plate on the bottom of the engine, to fix an oil leak, which meant removing the side stand cos it was in the way. So, of course, as soon as I had the bike blocked up & immobile on a lump of wood outside the garage, with the side casing open, it absolutely poured down with rain. Torrential for about 5 minutes, then on & off for an hour or so. Bugger.
Anyway, The clutch lever's stiffer than I'd like, but not un-useable. It turns the worm drive, which pushes the pushrod, which separates the clutch plates. All working O.K & I really can't see anything else that can be done to change any of it, but the plates only move a couple of millimetres. I don't know how far they should separate, but as I said, with the lever pulled in, I can slide a screw driver between them easily.
There was a little black dust in the oil inside the clutch basket when I took it apart yesterday, which looks like it's from the friction surfaces. I didn't soak the plates in oil overnight before fitting, but did dip them in oil when they went together -so maybe it's just that they're too dry, although they look oily & the engine's been run with them fitted. Would running it again once the new carbs are fitted oil them up & free them off a bit more? Or do I need to drain the oil again & properly soak them for a couple of days?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 12, 2016, 09:22:06 PM
Other jobs:
Front & rear wheel spindles replaced with shiny new ones -they were both quite beaten up from years of being wacked with hammers to fit them, with chewed up castle nuts & new ones were only about 10 Euros each from Germany.
Tried to fit the new speedo inner cable that Mr CopperSmith very kindly made for me, but the squared off ends don't flex like the rest of the cable so I can't slide it inside the curved guide tube. Think I've got some left over aluminium tube, so will experiment with bending it with a pair of brake pipe forming pliers with the inner cable already inside. Fortunately CS made a spare. Still need to connect up the illumination bulb in the new speedo, (Nathan hard wired the old one & the bulb's different).
Mr Dslam spotted that one of the triangular tappet covers on the top of the engine is an older type, that uses a flat paper gasket unlike the later ones which used a rubber O ring. I've found another late model one in my spares pile, but it needs a good scrub up with some wet n dry & chrome cleaner.
Offered the new stainless exhaust pipes up to the bike. Looks like they both need about 10mm cut off the cylinder head end to clear the frame. They're slightly bigger diameter than the old ones & I suspect I may have to go back to Torque Technique to have the bend on the righthand one pulled in a little tighter, but won't know for sure till I've trimmed the ends.
So plodding on, but very, very slowly.

Never bothered with soaking plates on Brits. Just oild them on assembly.
As long as all plates are flat, not warped, belled or twisted, there should be no need for a lot of movement
You may find that once the plates have bedded in, you will be able to change to the longer setting.
When I rebuilt the clutch on the A10 RGS rep., to begin with the handle bar lever had to be pulled right back hard against the grip and there was still some drag, but after a week or so of abuse it was much better.

Hi guys. Haven't oiled the cable cos it looks like it's got a PTFE, (self "lubricating" plastic), inner sleeve. It moves freely, so I think it's routed O.K
No, I've never soaked clutch plates before either, but several people have told me you should -maybe that's just on more modern bikes than I'm used to. If I put it in gear & rock it back & forth with the lever pulled in, you can feel the clonk, clonk of it being in gear. Several of my old bikes would spin the back wheel if it was off the ground with the engine running, when in gear with the lever pulled in, but wouldn't creep forward when they had the weight of a rider sat on them. Maybe it's fine & I'm worrying about it too much when it just needs bedding in?

Interesting -& thanks for the PM Tony. The clutch is back together, side casings on & filled with oil again, so I'm gonna leave it for now & move on with the other jobs in the hope that it just needs bedding in.
Trimmed 10mm off both new exhaust pipes at the engine end this afternoon, but the righthand one needs another 5 before it'll clear the frame tubes. May get away without having to go back to Torque Technique to tweak the bends, but it's not easy juggling 2 pipes that aren't bolted to anything yet & trying to measure gaps. Hopefully they'll work out O.K
Made a new speedo cable guide & cleaned up & fitted a replacement tappet cover.
Nice to see Mr Kapri at Loony's workshop this afternoon -you always turn up when I've got a list of jobs I want to get done Kev -I wasn't being deliberately anti-social, honest!  :)
I was stood in the lock-up this evening after trying the pipes in place again & thought I'd see how the lights looked in the dark. Put the key in, turned the ignition on ...nothing. Not a glimmer of light anywhere, no horn, indicators. Nothing. Bugger. Checked all the fuses & they look O.K. Just hope the battery hasn't had a proper charge yet & everything will be fine once it has, (have to charge it in situ cos the battery box drops out from underneath the frame & there isn't enough ground clearance -poor design). Really starting to get fed up with this now.

As you said earlier you could fit a screwdriver between the plates when the clutch lever was in so you should have more than enough travel on the clutchbasket to free it up. I would try it out for a couple of days of riding and see if its just needs some bedding in. It's a wetclutch so thats why some people say soak it, but it will soak in oil in the engine aswell.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 14, 2016, 07:53:40 PM
Trimmed a little more off the righthand exhaust today, where it pushes into the head. Not easy trying to work in 3 planes -trying to get the pipe to clear the front frame tubes without hitting the engine, but also need it to lay horizontally along the side of the bike & line up with the lefthand pipe. It has to exit the cylinder head at 90 degrees to the port as well. I've taped the new gaskets & the stainless washers that'll form the pipe flanges into the cylinder head ports.
I went to see the exhaust guy again this afternoon, about the 'zorsts on my truck, but had decided I didn't need to ask him to alter the bend on the bike pipe. Tried it when I got back this evening -yup, it needs tweaking. I think the bend that wraps around the frame needs pulling in a little tighter, which might also help it line up with the other pipe. One of those agonisingly slow, bit by bit kinda jobs, but I'd rather take it slow than hack a chunk off the pipe then find it's too short.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 14, 2016, 07:57:40 PM
The new pipes are 1/8" bigger diameter than the old ones, cos the bender, (maybe I shouldn't call him that), couldn't match the radiuses I had cos I'd made them from several different curves welded together. Being that much fatter in every direction, (like me), means less clearance everywhere. I'll continue tweaking & hopefully they'll end up where they're supposed to be.

New speedo cable guide made. It's an aluminium tube with a PTFE sleeve inside it & flared ends. Tried fitting it this evening, but the inner cable's about 1/4" too long on the bottom end, so I'll have to trim it with an angle grinder at Loon's workshop tomorrow.
No discernible progress, but things are gradually getting done.

I'll take it back to Torque Technique in Salisbury when I collect my truck exhausts in a few days. Trimmed a few mill off the speedo cable at loon's on my way home, tried it in place on the bike & found it needs a couple of mill off the other end now -so it'll be back to the workshop again tomorrow.

Really fed up with building stuff at the moment. It really is just the thought that I won't be doing this again that's keeping me going. Looking forward to the riding & driving, but the building bit's no fun at all.

Spent a couple of days on & off, fiddling with the exhausts, trimming the front end of the right hand one bit by bit to fit tighter around the frame tubes. The bend radius is slightly wider than the old pipe cos mine was a compound bend made from several different pipe sections welded together, which the pipe bendy guy couldn't match. The new pipe's also slightly fatter, to get the bends as close as possible, which messes up the clearance between pipe, frame & engine. Got another 5mm to take off the pipe end today, (no power supply at the lock-up so I've measured, dismantled, carted across town to Loon's workshop, cut with the angle grinder, ferried back & re-fitted half a dozen times). Can't get the pipes to line up, one above the other down the side of the bike though. Starting to think I may have to cut the right one, across the front of the engine, to pull it in tighter. Bloomin' annoying cos the whole point of the new pipes was to do them in one piece, cos the old ones had fractured where I'd welded them & ground the welds down flush. If I have to, I'll take them to someone to TIG weld for me. More expense, but as I said, I'm only doing this once.
Also got problems with the speedo cable. A small job but just not going right. Mr CopperSmith very kindly made me a new inner cable with the correct squared off ends to fit the speedo & drive unit, but it's slightly too long, (my fault not his). I had to make the angled aluminium guide tube with the cable already inside it cos the ends didn't flex enough to fit around the bend. So now I need to make a whole new set-up. Stuff it -I've ordered a new cable for a fiver from Ebay & will look again at having it shortened. Yet more expense.
Worried about the complete lack of life when I tried the ignition key the other day. Nothing. No flicker of light, horn or anything. The bike had been caught outside in the rain for 10 minutes the day before. Maybe something's shorted but the fuses all look O.K. Haven't got any means of testing anything, (or the knowledge to do it). It's a brand new battery & may not have had a proper charge yet, (has to be done in situ cos I have to lift the bike to drop the battery out from underneath), but there ought to be something in it. I'll see if I've got a test bulb somewhere I can put across the terminals.
Deadlines have come & gone & after thinking it just needed a quick carb tune up, I'm back to where I was 6 months ago. I love this bike & I'm really looking forward to riding it, but it's tough keeping the enthusiasm going when I'm endlessly pouring money & time into it & getting nowhere.  :(

Righthand pipe trimmed again. I've wedged everything in place with balls of masking tape to see how it sits.
The right pipe's a little closer to the frame down tube than I'd like, but if I cut any more off to bring it back further, it'll foul against the engine, so will do.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 19, 2016, 09:07:20 PM
The pipes need to run parallel to each other along the side of the bike -if the gap between them isn't equal all the way along it'll look horrible. The left one also needs to sit clear of the engine casing so it doesn't rattle against it. I can trim the back ends to the same length once they fit properly.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 19, 2016, 09:12:52 PM
But the top, (righthand), pipe hangs out beyond the lower one by about 1/2 an inch. That just looks wrong, as well as meaning the hot pipe'd be closer to my ankle when riding.
So it looks like I'll have to cut the right pipe where it crosses in front of the engine & remove a section. Once it's welded back together that'd bring the 2 pipes into line. I hope.

Are you sure you want them the same length - I think they look rather good in that pic!

 :D The first set started off slash cut the other way, to follow the line of the frame. By doing that, by sheer chance, they ended up exactly the same length. I won't trim them until they fit properly.
Rain here this morning, so I gave my truck project a miss after work & worked on the bike instead. Then the sun came out. Decided to bite the bullet & cut the righthand pipe. Spent 2 hours after work trying to juggle the 2 pipes & decide how much needed cutting out. In the end I just took a centimetre out. Seems to be about right.
I'd hoped to get them over to my mate Bernie in Berkshire for TIG welding but ran out of time, so will go after work tomorrow.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 08, 2016, 10:24:22 PM
Hmm, really struggling to raise enthusiasm for this at the moment.
Drove over to Berkshire after work this afternoon & collected the stainless exhausts from Bernie the TIG welder. He's done a lovely job -I literally can't see the join, (I had to cut the righthand pipe in half & take a centimetre out of the middle, where it passes between the frame tubes). As well as welding it back together & buffing out the weld, he added the flanges to the ends. 30 quid.
Great. Unfortunately they still don't fit. The left one's not too bad, but the right fouls on the frame down tube. Not Bernie's fault -I had to guess at how much to take out & what angle the 2 pipe halves should go back together at. Maybe pulling the bend in tighter at the cylinder head would help, but I'm not sure. I'm almost tempted to cut a small piece out of the side of the pipe & reverse it, so that it curves inwards to clear the frame. That would mess up the gas flow, but it's not a race bike, just a daily rider.
I think I need to add a second pair of gaskets in the ports too to pack the pipes out, as the finned collars bottom out against the cylinder head before tightening up on the pipes.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 08, 2016, 10:36:46 PM
The back end's giving me problems too.
The previous pipes, which were smaller diameter, were held with a pair of circular clamps, which bolted to a stud welded to the frame, with a small gap between the 2 pipes. Because the new ones are a bigger diameter, they need to lay tight together down the side of the bike. Which means I can't use the mounting stud. I'll have to cut it off the frame & touch the paint in, but at least it'll be hidden behind the pipes. So, how am I going to clamp the 2 pipes together & attach them to the frame? Any ideas? I've already drilled & tapped a 6mm hole in the frame tube to fix the back end of the chainguard, so I think I need some kind of stainless strap that wraps around both pipes & hooks over the frame, bolting to the chainguard mount.
I've got baffles to go in the end of each pipe, so could drill through the strap & into the pipes, then bolt through into the captive nuts inside the baffles to hold the pipes inside the strap. That'd work.   


Title: Re: Manky's XS650 Yamaha
Post by: Olds on July 09, 2016, 03:58:42 AM
Looks to be almost there. Unless the clamps are crushing the exhaust gaskets rings slightly, you don't really know how the tubes are going to fit. Add a spacer between the clamps and the flanges (not double up the gaskets).
How long are the flange rings and are they in the right place ? Seems they should be 7mm mounted 8mm from the end of the pipe (std diameter pipes).


Title: Re: Manky's XS650 Yamaha
Post by: Mendalot on July 09, 2016, 07:25:40 AM
Andy, I made these brackets from sheet stainless steel and have some left over if you would like it. Could you not make up two sleeves that wrap round each pipe and clamp to your stud if you cut it down. (obviously not with the ugly hose clip though ;))

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 09, 2016, 04:04:33 PM
Aah, didn't think of that Dave -my flanges are welded flush to the end of the pipe, (I think Tom's got my original down pipes so I had nothing to compare to). When you say how long are they, you mean how thick? They're 2mm. So how thick do the spacers need to be?
Appreciate the offer of the stainless Sir. I think I'll do something similar, but in 25mm x 1mm stainless strap. The pipes need to sit right where the stud is, so it needs to come off, then I'll try & make a strap that's kinda figure of 8 in profile with a curved tab that'll sit over the frame tube.


Title: Re: Manky's XS650 Yamaha
Post by: Olds on July 09, 2016, 07:49:44 PM
I assume 5mm. But it depends on the finned clamping rings. Best bet is to put a bit of plasticine (or similar) on the pipe, between the flange and the clamp ring. Push the pipe right into the head (without gasket ring), push the clamp ring against the head to compress the plasticine. That should tell you how thick it needs to be, to compress the gasket and leave a small gap between clamp ring and head.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 15, 2016, 07:51:05 PM
A bit of a guesstimate, but I went with 6mm thick stainless spacers, custom made by:

http://www.lasermaster.co.uk/easy-order

for about 7 quid the pair. I didn't think they'd slide up the pipes & around the multiple bends, but surprisingly, they did.
I've modified the rear mounting on the chainguard & am waiting for some stainless flat strap to turn up in the post so I can make a new clamp for the back end of the pipes, to fix to the same bolt as the chainguard. Still looks like I'll need to recess the front of the righthand pipe to clear the frame, but have to cut off the old rear exhaust mounting stud cos the pipes don't sit right with it in the way.


Title: Re: Manky's XS650 Yamaha

Post by: Manky Monkey on July 17, 2016, 08:34:01 PM
Exhausts tried in place now the stud's out of the way. They don't fit. They will fit, but need some cutting & tweaking to sit right & line up with each other. Really needs to be done on the bike, rather than me cutting & marking them & taking them one at a time to the TIG welder, (I'd have to do one, then get the other to match it). The ideal person would be my brother Steve, who's got the space to have the bike in his workshop & can play with it at his leisure. He's done me a lot of favours but I'd rather pay him the going rate as he's self employed & I don't want to outstay my welcome. I'm resigned to this thing taking as long as it takes now.
Both pipes need pulling in at the back end & do flex a bit but I don't want to bolt them up under tension or they'll end up fracturing or cracking the head. They also need to line up one above the other.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 31, 2016, 11:02:29 PM
Had to attend a family get-together this weekend, which involved staying overnight at my brother's place in Wiltshire. So I rented a van & took the bike over to his workshop & blagged an afternoon of his very valuable time to sort the pipes out.
We ...he, ended up cutting a small slice out of the inside of the bends of both pipes to pull them back into line, then TIG welded them back together.
He also made up a threaded stainless steel bar to connect together a pair of clamps I supplied & a stainless tab to bolt them to the frame, using the same mounting bolt as the chainguard.
We drilled the ends of both pipes & bolted the 12" long stainless perforated conical baffles in place with the captive nuts I'd welded inside them. So the baffles are right at the far end of the pipes. No idea if they'll make a difference, but worth a try.
The exhausts need to come off the bike again so I can repaint the frame tube they clamp to, so I'll make sure they line up directly above each other when they go back on.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 31, 2016, 11:06:35 PM
Because the new pipes are slightly fatter than the old ones, they fouled on the frame down tube. We thought about cutting & tweaking the bends again, but in the end decided to simply cut a 10mm deep section out & TIG weld a reversed section of pipe back in to create a recess which wraps neatly around the frame, as if we'd designed it that way in the first place -if anyone asks, we did.  ;)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 31, 2016, 11:15:38 PM
We discussed various ways of finishing the pipe ends -slash cut to follow the top frame rail, slash cut the other way to follow the mudguard struts, etc. I had the final say though & decided on simply cutting them level, a couple of inches shorter than the last pipes to clear the rear wheel spindle, should I need to take the wheel out. Being slightly shorter also visually shortens the back end of the bike, which I think looks right.
My big brother Steve, (Brock), trying it for size. 
Now safely back in my garage in Basingstoke -the bike, not my brother.
I'll take the modified chainguard back to the powder coaters for re coating, as well as the side stand which has some weld spatter on it under the coating which really annoys me, then repaint the frame tube where I cut the old exhaust mounting stud off. Mr Loon resprayed the tank on Friday so once I've cut & polished that it can be bolted back on. Then I just need to chase up the speedo cable I ordered & get the bike over to Mr Dslam's workshop for carb fitting & tuning.
Very nearly there.

Speedy Cables contacted -mine's "on this week's order sheet".

Frame tube sprayed in high build primer, rubbed down & sprayed in gloss black. Had to mask the area around it with paper towel, cos that's all I had to hand at the time.

Still waiting for the 2nd cable.
Dropped some parts in the garage this evening, glanced at the bike frame -bugger. The little bracket that holds the exhausts away from the frame, that I painted the other day, is at the powder coaters at the moment. So I'd wedged a folded bit of cardboard between the pipes & the frame to stop the paint getting scratched. Seems it wasn't quite hardened cos when I pulled it out, it's pulled the surface off the paint.
*sigh* Rub it down & do it again.

Re-sprayed frame doesn't look too bad now & the few marks left by the cardboard being pressed into the soft paint won't show when the pipes are on.

Tank's got a few bits of grit in the paint -one of the joys of Mr Loon working in an old farm building. His new unit's purpose built & will have a dedicated spray booth. Hopefully they'll polish out, but if not, he says he can re-spray it on the bike. New breather pipe fitted underneath it, as well as a pipe added to the breather at the back of the cylinder head.
Various other odds & ends tidied up. The exhausts are off again while I get a local engineer to turn down the finned collar on the left one. For some reason it doesn't bolt up tight to the head, although the pipe is located properly. Maybe the exhaust studs are shorter on that side or something, but I can only get a couple of threads on the nuts, whereas the other side has plenty. A minor problem.

Side stand re-fitted so I can move the bike outside again. There was some weld spatter on the foot of it, underneath the coating, which really annoyed me. Sorted now.
I've fitted the new stainless steel return spring, which I bought about a year ago. Because it's stronger than the old one, it was a real bugger to fit. With the bike sat on a block of wood & a couple of zip ties looped through the spring & a spanner to pull on, I spent an hour laying under the bike, trying to stretch it into position, with the bike threatening to fall off the wood & topple over on top of me. I very rarely swear, but certainly vented a bit at that. Thankfully done without incident.
So I've just got to wait for the engineer to fix the exhaust clamp, re-fit the pipes & it's ready to go back to Mr Dslam for carb fitting & tuning. Back to where I was 6 months ago.   :P

I know not everyone reads every section of the forum, so for those that don't, Mr Loon is moving workshops, which means he needs more storage space for all the stuff he's hoarding for future projects. So I've given up my half of the lock-up garage we share & have started renting one from a little old lady who lives at the end of the street I live in.
The bike's not quite finished, but it wasn't worth renting a van just to ferry it a couple of miles across town, so I decided to push it. Used to push broken down bikes all the time -but that was 30 years ago. I also chose the most humid & sticky evening of the year so far to do it. Took an hour or so, with lots of stops to get my breath back, but the bike's now safely installed in a garage within sight of the house I lodge in.
Not much I can do on it till the engineer machines the exhaust clamp, so I'll look at making the garage more secure & weather proof.
Catching my breath on the footpath that runs behind the local cemetery.

Me or the bike?
Got the finned exhaust clamp back from the engineering workshop today. They milled 5mm off the face of it cos it didn't pull up tight against the cylinder head. No idea why, but it should work now.
Having moved out of Loony's old workshop, I rent 2 lock-up garages, about 2 miles apart. One is home to my pick-up truck, my welder, (although I've got no power supply to use it), & most of my tools. The other, slightly smaller one, houses the bike & my Dad's old wooden workbench.
I spent an hour this evening driving back & forth between the 2, searching for the exhaust fittings for the bike. I visited both garages twice before finally finding them among the spare parts crates in the bike garage where I'd started. I suspect that'll be the pattern of things now -constantly flitting between garages, moving spares & tools from one to the other.
Too dark to re-fit the exhaust pipes by the time I'd sorted everything out, so I'll do it tomorrow.

Post by: Manky Monkey on September 07, 2016, 09:30:07 PM
So-o-o hot 'n' humid today. Shouldn't complain, but by the time I got home form marching round the streets delivering the Mail I was absolutely drained. Not sure if the job's getting harder -O.K, I know it's getting harder, or I'm just getting old -& I know I'm definitely getting older, but I need recovery time now between getting home & starting the afternoon's jobs. So it was tea time before I walked down the road to the garage & took a look at the bike exhausts.
No dramas fitting them, though I may replace the gasket in the lefthand port cos it looked a bit squished from last time the pipes were bolted up. Have to wait & see if it blows when it's running.
So now I've got stainless steel pipes, 1/8" bigger diameter than the old chromed ones, with 12" long conical perforated baffles in the tail end of each one. I've fitted a small heatshield to the top pipe, which I picked up at a swapmeet ages ago for a couple of quid. It's just held with 2 stainless Jubilee clips. I'd previously tried a longer one which required a couple of threaded inserts welded into the pipe, but I think the shorter one looks better & should still keep my leg off the pipe, (actually, with my foot on the peg, my leg's an inch or two off the pipe anyway).


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on September 07, 2016, 09:50:54 PM
The 2 pipes aren't exactly lined up, one above the other, but they only fit in one position & they're near enough that I'm not going to worry about it. The tail ends are held with chrome clamps around the pipes that bolt up to a single tab bolted to the frame, that also holds the back end of the chainguard.
Jobs left to do:
fit & tune the new Amal carbs.

Re-charge the battery & check the output to see if it drops overnight, cos last time I tried the ignition there was no life there at all, despite it being a brand new battery. Nathan, (Galaxie500), wired the bike, but hasn't given me a wiring diagram & I've no idea which fuse does what.

Rub a couple of "bits" out of the paint on the tank. Loony sprayed it in his old workshop, which was on a farm -dust in the wet paint was an occupational hazard there, but usually cut & polished out. If not, I'll sand them out & blow the tank over again on the bike in aerosol paint.

Do something with the sidestand -the bike doesn't lean over enough & stands almost upright when it's on the stand. Parking on a camber, or someone nudging it as they walk past, would see it toppling over. So it needs either heating & bending very slightly, or cutting a slice out of the middle, then drilling, pinning & welding the 2 halves back together.
As a side issue -or sidestand issue, why do kids nowadays think you should kickstart bikes while they're on the stand, by standing to the right of the bike & giving a huge, theatrical leap on the kickstart? It's a sidestand, not a kickstand. You ain't gonna look so cool when it snaps under the strain & the bike crashes to the ground with you sprawled on top of it. Stand astride the bike, flick the stand up, lean it over to the left slightly so the kickstart doesn't hit the ground at the bottom of it's stroke, & give it a firm, measured kick.
I know why they do it -cos that's what they've seen Harley riders doing on Sons of Mediocrity or whatever. You're English, riding Japanese bikes. Not necessary & looks ridiculous.  >:(

MOT it & tax it, (it's already insured). I'm slightly concerned about the tax cos the V5C shows it as Disabled Tax Class, (tax free). I'm hoping it's just a matter of going to the local Post Office & asking them to change it.

Ride it, lots & lots. I haven't ridden at all for 5 or 6 years, but hopefully I still remember how to.  :)

Old school Jap bikes are very trendy at the moment with the Hipster bike crowd. They don't remember kickstarting old Japs, or Brits before that, as my generation did, so just do what they see on the TV/internet cos they think it looks cool. I think I'm just getting old & grumpy!
With Harleys, you need a decent swing cos they're so much bigger capacity -2 or 3 times the cc of an XS, but they have huge kickstands, designed just for that reason. Tsk -kids!  >:(

Looking great Andy. A nice, cool bike with a lot of detail without it shouting 'hey look at me'.
With the side stand issue I'd be inclined to heat and bend it out a little, rather than shortening. Be slightly more stable that way. Probably best to bend it just below the spring attachment point.
I miss having a centre stand on bikes. Not for starting a bike on as that was a near sure way of having a bike fall on you, but for maintenance and the like. You can't even check the oil level on some bikes without someone else holding it vertical.

After trying one of these at my mate's place, decided to invest in one - great for maintenance jobs, incl lifting the rear wheel, but you do need a minimum amount of ground clearance to get the thing in place.
Saying that, if a mate helps lift the bike to start with, or one end of the bike is raised, say by wheeling onto some wood, it can be slid into position.
It can also take some of the weight off the tyres if a bike is left to stand for a long time.

Mr 'Slam isn't available for a couple of weeks yet, so I busied myself today fitting a pair of "Armadillo" locks to the garage door. All went surprisingly well until I was sweeping up at the end of the job & walked straight into the edge of the open door. Now sporting a large bump on my forhead. Yes, I did swear -quite a lot.
On the plus side, the locks should keep the Armadillos out.

Spoke to Mr Dslam this afternoon. He's fully booked for a couple of weeks, so it'll be early October now before he can take a look at the bike. Thinks he can sort out the flat battery & sidestand issues, as well as fitting & tuning the carbs though, then MOT it locally for me. If all goes well, I should be able to ride it home.  ;D So for now, it sits in it's own lock-up garage, awaiting collection.

Post by: Manky Monkey on October 05, 2016, 08:33:44 PM
Following on from Mr Spanners' recent post, I've been thinking about converting my kickstart lever to an American style flat pedal too. I kicked the bike over with the old Amal carbs on & it kicked back, giving me a whack on the arch of my foot that left me limping for days -a joy I'd forgotten from my youthful biking days. Hopefully the new, expertly tuned carbs will cure that problem, but I'm still thinking of converting the pedal anyway.
So I bought a repro Harley pedal rubber from Ebay for 4 quid. Looking at the slot in the end of it, I'll need a tube with 2 flat blades for it to slide onto. I guess the original pedal arm would need turning down -although it won't fit in a lathe & would probably be just as easy to reduce by hand with a file. A steel tube with a brass sleeve in each end would do the trick, (the pedal needs to rotate on the lever as you kick it). The new rubber's longer than the original so maybe drill & tap the end of the original lever & use a bolt with a large washer through the end of the rubber to retain it?
Some of the American XS guys machine a whole new arm & TIG weld it to the old lever, or in this example, weld a 10mm stud to the end of the original arm.
Just something to tinker with over the Winter.

We rolled into the nearest station & he jumped off & wandered over to the kiosk. To our surprise the cashier leapt up, locked the door & grabbed the phone. What the ...?
Turned out she'd seen a bunch of bikers arrive & one approach her with what looked liked a shotgun hidden in a blanket. She thought we were going to rob the place.  :D

They're vicious, spikey looking things!
I picked up a short length of 12mm i/d stainless tube the other day. That would be a good fit on the lever & fits nicely inside the rubber pedal I've got. Then I could weld flat plate either side of the tube to support the pedal, but there's no room for a brass bush of any sort inside it. I'm probably over-thinking this & it doesn't need a bearing or bush, just a good coating of grease.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 06, 2016, 11:29:40 AM
A quick update for those that have asked-
Mr Dslam has a relative who's currently in & out of Hospital so he's not available to work on the bike for a while. Not a problem. It's safe & secure & sitting in it's own lock-up garage until he's ready to tackle it. Some things are more important than vehicles & I'm in no rush. Quite happy to admit I'm a fair weather rider these days -I wouldn't be out on it till the Spring now anyway, so it's there when he's free to do it.
In the meantime, I'll buy a second kick-start lever on Ebay & see about modifying it to take the American style pedal rubber.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 23, 2016, 11:17:31 PM
Mr Dslam's due to collect the bike tomorrow morning, to take to his place in Surrey for a bit of fine tuning.
In the meantime, I've been playing with a kickstart pedal. I bought a spare lever from Ebay in case I buggered up the original.
I sanded down the arm, using a flap wheel on the angle grinder, from about 15mm to 10. I've got a length of 12mm O.D stainless tube, which fits nicely inside the repro Harley rubber pedal, so that now slides over the arm with enough freeplay for a slap of grease between the two. I wondered about bearings & brass bushes & stuff, but decided it didn't need to be that complicated.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 23, 2016, 11:20:02 PM
The Harley style rubber's closed at the small end, so I used the stainless tube & a heavy hammer to punch a hole through it. Then I nipped to the local tool shop for an M10 stainless bolt & a couple of stainless washers.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 23, 2016, 11:21:54 PM
Stainless tube cut to length & the bolt cut down to suit. I've chamfered the ends of the bolt & the arm for better weld penetration -don't want it snapping off when I swing on it.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 23, 2016, 11:28:26 PM
All put together to see what it looked like, but not yet welded.
I was going to use a Nyloc nut, but decided a stainless dome nut would cause me less injury should my foot slip off the pedal. I trimmed the bolt thread down until the nut bottomed out on it before it pinched the rubber up tight -the pedal has to revolve as the lever's swung to keep it flat under my foot. I'll ThreadLock the nut in place.
I've just leant my welder out for a few months, so now need to find someone to weld the bolt to the arm. It also needs a pair of triangular "wings" cut from flat stainless plate, to weld either side of the tube, to support the pedal, (the inside of the rubber's slotted to take them).
After quite badly bruising the arch of my foot kick starting the bike last time it was at Dslam's house, I hope this'll be more comfortable to use for an oldie like me.
Once it's welded, I'll get the lever powder coated black to match the gear lever on the bike.

Nice to see Mr Dslam this morning.
He arrived with a van & collected the bike. It's going back to his workshop in Surrey for a bit of final fettling &, (hopefully), an MOT. Several jobs for him to do -fit & tune the new Amal carbs, heat & bend the sidestand a little so the bike doesn't stand quite so upright, check the wiring over & charge the battery, (no power at all last time I tried the key in the ignition), fit the appropriate sized fuses in the box as it's currently got 4 25amp ones fitted, & generally do anything he deems necessary to get the bike running & riding properly. I fully trust his judgement, so if he decides something needs changing, he has a free hand to do so -no point it being pretty if I can't ride it. I can build a bike around an engine, but I don't claim to be a mechanic so I'm happy to defer to his greater experience. 
Looking forward to the road test report.  :)

I'd forget to check the tattoo -or that I even had a tattoo!
I did think about centre punching the 12.0.clock position of each screw, but then realised it'd have to be done in situ & would probably snap the brass heads off.
Found this video of one of my favourite XS chops earlier. Has the same cast aluminium inlets, Amal carbs & air filters as mine. This is how I hope to be spending much of next Summer.

As an alternative to the Amals, round-slide Mikuni VM32 carbs are considered good, so maybe worth some investigation too

Poo -& hurrah at the same time. Appreciate your time Sir.
It was a brand new battery, but I guess it's been sitting around for a fair while. Do you want me to PayPal you some pennies Andy?
I need a photo of the carbs with the new shiny brass thumbwheels! -you know, the ones specifically designed so that passers-by can twiddle them & completely bugger up the tuning.

You mean the twiddly things that passers-by can remove and leave you stranded !!!!

Me thinks a spare set in your pocket along with a crib sheet so you can fit the replacements (and set 'em up) might be a good idea  ;)   ;D   ::)

Post by: Manky Monkey on November 27, 2016, 10:28:04 AM
 :D Yeah, I do suspect I might be asking for trouble with them -but they look so pretty!
Mike, they're 930 Mark 1 Amals, as used on loads of British 650 twins. Bought new from Burlen Fuel Systems in Salisbury, (I went there & collected them in person). Already forgotten the cost, but something like 100 quid each. Andy, (Dslam)'s, currently fettling them, so can tell you exactly what jets etc are in them.
I've used a pair of 34mm Dellortos with accelerator pumps on one of my old XS chops, bought from their place in Reading, Berks, (no idea if it's still there). Hugely improved the performance but did drink fuel by the bucketful.

Minor problem with the brass twiddly things for the Amal's. They don't fit. The threads are poorly cut or the threads in the carbs have changed profile since Amal re vamped the MK1's. The throttle stop screws and mixture screws supplied with the carbs fit fine so I suspect the brass ones. I am going to setup the carbs with the Amal ones then decide what to do with the brass ones as his Mankyness is rather keen for them to be fitted. Might be able to rethread. We shall see.

Got the XS running. Called Mr Mankey to let him hear it. She's loud! Anyhow, got the pilot and slide cutaway just right but the needle needs to be dropped a notch but a lovely slow tickover achieved.
Started on the sidestand mod which is slightly too long and the bike sits too upright.
Easy thought I. Ignite the gas axe, a bit of heat applied and Robert would be your mothers brother but on closer inspection if I bend it out the spring will foul, if I shorten it the spring mount will be on the ground.
Bend it forward it is then!
I will have to make the upper spring mount stronger as it is bent and the oval hole that locates it has gone nearer round than oval. Will remake that as well then. Where's me file gone?
Onwards and upwards or forwards. You know what I mean.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on November 29, 2016, 07:43:05 PM
I like to spread the joy of tinkering around :)
I did indeed hear it & can confirm it's rather louder than I'd expected :) Larger bore stainless pipes have definitely amplified it's rortiness. Hard to tell over a mobile phone in a shed, but if it proves too much, (not just for the MOT, but also for comfortable riding -no fun if it gives me a pounding headache every time I take it out), I'll look again at the previous plan of adding a double entry/exit silencer in the middle.
Andy's convinced the left rear indicator, right behind the exhausts, will melt into an unrecognisable drooping blob of plastic within the first few miles. I disagree & think the vibration will shake it to bits before that happens. Either way I reckon I'll be shopping for some small black aluminium replacements fairly soon.
Otherwise, progressing fairly well I think. The motor seems strong & mechanically healthy & Mr 'Slam's still talking to me so presumably I haven't committed too many engineering or styling crimes in it's execution. :)

Thanks to Chris for posting these for me, (used up my data allowance on my laptop & the next lot doesn't kick in till tomorrow, so posting this from my phone).
Kickstart pedal parts cut from an offcut of 3mm stainless steel plate, picked up on eBay for 5 quid. The Christmas rush is well underway at the Post Office now, but I finished work early enough today to nip over to Berkshire to see my mate Bernie the fabricator, who TIG welded them together while I waited for another fiver.

Spent some time on the XS today. Carbs sorted. Runs fine, ticks over fine but a tad loud.
The engine itself is whisper quiet. Quietly whirring away and sounds great when revved. The new Premier Amal (Spell check wants to insert 'anal'!!) carbs are so much better than the previous offering.
The indicator, near side rear, seems to have succumbed to the vibes and heat as its rather close to the exhaust outlet so I shall cobble something together for the MOT. Just waiting on the MOT-able number plate then it's MOT time.

Okey doke.
I might just go for something boring but reliable, like these. Used them on several trikes & bikes. I've powder-coated them black a few times & fitted amber lenses from Halfords dashboard warning lamps into the back of one pair so I could see they were flashing.
Of course, being a 1980 registration, it doesn't actually need indicators, ('86 onwards), but in the murderous mayhem of modern traffic, they just make self preservation sense. I do plan to re-register the bike through MSVA, but will ride it for a Summer first to iron out any teething problems, (& get some enjoyment out of the thing after several years of building), then get it tested over next Winter.
Already thinking of riding it down to Romsey in Hampshire on Boxing Day morning for the annual classic car & bike meet as I won't be taking the Pop out now till the Spring. Seriously considering developing an illness in June to take a few days off work for the Flanders Chopper Bash in Belgium too.
Getting back on a bike after 6 years away from them is a little daunting, but I really want to clock up some proper mileage on this ride.  :)
 


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 06, 2016, 04:50:19 PM
I can't take any credit for the engine. I've delved into it to replace the clutch & gearchange linkage, as well as fitting new filters & an oil change, but that's all. It's all looked very clean when I've removed any covers -no burnt on black oil deposits or anything. I bought the original donor bike from a car dealer in Yorkshire, who took it in part exchange from an old man who couldn't ride any more & needed a car. So hopefully it's either very low mileage or well looked after.

My only worry at the moment is that it's taxed as a disabled vehicle, (free tax), which was presumably because of the old guy who used to own it. I'm hoping changing it's tax status will just be a matter of ticking a box on the online form, but with my luck it'll mean getting the bike inspected or something.
Really looking forward to getting back on 2 wheels -loved hotrods since I was a school kid, but my first experience of the road was on a bike & they've remained my true love ever since. I know I'll be extremely slow & wobbly to begin with, but can't wait for that first ride in the Spring sunshine.

Agree you'd expect the post office to be able to look up the MoT online, but following the example of my friend only a couple of weeks ago, I'd still suggest taking the MoT.

This friend needed to tax his car which was on a SORN and for some reason this couldn't be done on line.
A phone call to Swansea (and a genuinely helpful person) did some delving and revealed the ref number on the V5C wasn't, for an undisclosed reason, being recognised by the system.

Hi Boss,
Had a few issues. Not all with the bike!!
Can you give me a call mate. The PM thingy doesn't seem to be working and my mobile got changed out and all my contacts went walkies. POOO!


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 19, 2016, 09:07:02 PM
Hmm. Well, just got off the phone to Mr 'Slam.
A sudden family bereavement means he just can't commit to any more time on my -or anyone else's -bike & has led to him re-evaluating things in the past few days. Life's too short & there are far more important things than bikes -my sentiments, maybe not his.
So the XS will be heading back soon, with the carbs sorted & engine running nicely, but a rather daunting To Do list. Not quite back to the drawing board, but definitely back a few pages.
Andy's going to jot down a list, but it's basically:

Clutch still dragging, despite me having replaced every single component in it, from the lever, to the cable, to the worm drive to the pushrod to the plates. Not quite sure where to go with that one.

Battery not charging. It's had 2 new batteries now. Could be the alternator, could be the rectifier, could be the actual wiring loom. I suspect it'll be getting re-wired. Again.

Needs more fuses. It's got 4. Andy would prefer to see 6. I'd already decided to swap the old glass style fuse box for a newer blade fuse type anyway, as I've had problems with British bikes in the past, vibrating the fuses apart. So now would be the time to do that & maybe mount it on the inside of the left side panel for ease of access.

I've also already decided the rear brake master cylinder needs changing -my brother Steve made up a beautifully engineered cross shaft across the frame from the pedal to the master cylinder on the other side, but the return spring bracket hangs low under the bike & makes it a real pain to roll up a ramp into a van, which is how it seems to be travelling a lot at the moment. I'll swap the whole set-up for a more common Harley type cylinder mounted directly off the pedal. Much simpler.

The rear brake torque arm needs some modification. Not a lot, but the current set-up means that under really heavy braking it'd be possible for the caliper to move over-centre & swing around the disc. A second locating tab on the frame should fix that.

The indicators really do need replacing with something sturdier & the rear ones need moving away from the exhausts. As It's a 1980 bike, I could just bin them, but I'd like to live a little longer yet & modern drivers have probably never seen a hand signal. I plan to SVA the bike at some point too, so flashers will be needed then.

My second set of very expensive stainless exhausts are just way too loud for regular use. Again, really not sure what to do with them. Splicing a stainless dual entry/exit silencer into the middle seems to be the only real option, but I've no idea how much difference it'll make.

I think that's about it. Certainly enough to be going on with.
Really sorry to hear your news Andy. Thanks for all your help mate.  ;)

Post by: morrag on December 19, 2016, 11:25:04 PM
Well, that's a shame that your buddy has probs. but of course, family considerations are paramount. As for 'the list', don't be too hasty, as the clutch may be no more than putting miles on it to remove any " fluffy-ness", assuming of course its lifting squarely, and has a full compliment of shims and/or any spacers, in the correct locations. The generator is easily checked by anyone who understands auto-electrics, and would confirm, or otherwise, the state of play. Sounds like the rear calliper does indeed need to be fixed in the positive manner, not as a "floater", and the master cylinder fix you have covered. Put a pair of cheap and cheerful after market indicators on until you have more time to fix/consider the preferred final result! As for silencing, maybe a bypass baffle insert would suffice, removing baffles in turn until the acceptable noise level is achieved, not so much really.....if you say it quickly!! ;D ;D ;D..Morrag

Post by: Manky Monkey on December 20, 2016, 05:29:25 PM

Andy's returning the bike on Christmas Eve, so I'll take a good look at it over the Christmas break. It's a shame to re-do stuff now it's all nicely coated & painted, but if it has to be, it has to be. I fully intend to keep this bike forever & never build another, so it's worth taking the time to get it right.
The clutch plates barely seem to separate, despite having all the right components in place. I put them in dry though, so it might just be a matter of taking them out & soaking them in a tub of oil for a week then replacing them.
I remember Nathan was baffled by the alternator/rectifier arrangement for a while -he's a car guy & had never wired a bike before -so it may just be wired up incorrectly. I don't understand electrics at all, but have a Haynes manual, so hopefully someone more competent can check the wires are actually going where they should.
Explain your bypass baffle to me Mr M.

I think that the standard xs charging systems are known for being rather useless. You can replace it with a Yamaha RD400/LC350 PMA but it needs an adaptor plate. Might be worth considering a PMA instead of the brushes if this is a long term bike, less maintenance and improved reliability?

Mr M the baffles I believe I have seen on Demon Tweeks, and as regards your electrics, the brushed system on the Yamaha isn't crap, but is less efficient than a permanent magnet system, however, if you are only running basic system loads, and you don't mind changing a set of brushes, a simple job, every couple of 3 years, then the original system should, will, suffice, particularly as you no longer have an electric boot! Just get someone who knows the system, or who is familiar with this type of charging arrangement, to check the output before and after the reg./rectifier unit, and that will reveal the state of play, Morrag.

Suggest you have a think about going down the Permanent Magnet Alternator route.

Its an upgrade using more reliable, and potentially more easily available, components.

For the exhaust baffles, stainless perforated tube half the diameter of the pipe, make a collar for them and fit, tune with fibreglass silencer wadding. Seeing as that's how oem exhausts are made I'd try that. Make them as long as possible then trim them until you find a noise level you like. Just like stumpy did on twisteds trike.


Title: Re: Manky's XS650 Yamaha

Also, does the master cylinder really need changing, if it's only a problem loading it in a van? It's not like it's going to catch when you're actually riding it is it?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on December 21, 2016, 11:42:14 AM
No, but it'd also free up space in the electrics box as the remote reservoir's in there. I'll have to repaint part of the hardtail to modify the caliper anchor arm, so thought I'd do it at the same time. The Harley style units are just a nice, self contained little thing.
I'll try something like perforated tube or Morrag's corkscrew type baffles first before cutting into the pipes.

Fair enough. For the exhaust it's all about disrupting the gas flow. Even a series of bends will help, obviously not on this, even cutting the perforated tube into smaller sections and staggering it should work.

Post by: morrag on December 21, 2016, 12:01:28 PM
A perforated tube may be a simpler option in fact, so long as the desired level of "Quietness!" is achieved, re. the generator, I still run a mid 60's Triumph, which has a single phase, 6v. alternator, albeit of perm. mag. type, but with inferior output to your system, and its adequate. As stated, if you had a starter motor then it might be a little different. The modified route is superior, output wise, but if that level of output aint required why bother, and hey, we all used Dynamos with brushes for many, many, years, so.... :D..Morrag

Some light reading if you've a spare hour or ten............. ::)

http://www.xs650.com/search/2558977/?q=fitting+clutch+plates&o=relevance&c[node]=2


Worth noting its recommended practice to soak the clutch plates overnight before fitment.


Quietening the bike - "Splicing a stainless dual entry/exit silencer into the middle seems to be the only real option, but I've no idea how much difference it'll make."
Siamesssing (if its a real word) the pipes is certainly a method of making it a little less noisy. It should increase the toque a little bit too. (I used to run a 650 Triumph hillclimber with a siamese system, merging close the head into a single pipe, and it was surprisingly quite)

Try tieing the clutch lever back to let the tension off the plates.
when I changed the clutch on mine there was a label on the box that said to soak the plates before fitting

on the wiring lose the old loom and just wire in the basics there some info on here for that

Post by: Manky Monkey on December 24, 2016, 06:34:59 PM
Nice to see Tony & Andy this afternoon -the Boys from the Bike stuff.
They brought the XS back from Andy's workshop in Surrey for me. I'd actually started to forget what it looked like. Thanks chaps. Much appreciated.
We rolled it off the trailer & Andy fired it up first kick. Didn't sound too bad -until he blipped the throttle. O.K, yeah, that's a bit loud! So it definitely needs some experimentation with the exhausts. As they said though, I still have the old chromed steel pipes I made to practice on before cutting up the new stainless ones. The old 'uns are a slightly smaller bore, so won't sound quite the same, but will give some indication of what works & what doesn't. I can make bolt in baffles for the stainless pipes which can be fitted without alteration, but if I go for an inline silencer I'll have to cut both pipes in half.

The clutch lever's far too stiff & the clutch is dragging, (not disengaging fully). The clutch springs were torqued down to the correct setting when I fitted them. I know you can buy stronger competition springs, but can you buy weaker ones?

Although Nathan did a nice job of the wiring, the sections connected to the LED indicators are very small gauge -fine for the power involved, but not really robust enough for a thumpy old twin. The loom's completely hard-wired -no connectors anywhere, just soldered & heatshrunk. Again, that's fine, but means you can't disconnect anything without physically cutting the wires. Not ideal when you need to check things like the charging circuit. A more basic re-wire may be the easiest solution, though certainly not by me, (I really don't understand electrickery). A new fusebox with blade fuses rather than vibration sensitive glass ones would be a good idea too.

The indicators are nicely quirky, but just not man enough for the job. They need to be replaced with something more robust & the rear ones mounted higher, out of the line of fire from the exhaust.

Even with Andy's low slung trailer, we still had to roll the bike halfway down the ramp, then lift it the rest of the way as it grounds out on the rear brake return spring bracket. If I'm going to rework various parts of the bike, I may as well sort that out by fitting a simpler custom Harley style master cylinder next to the pedal. 

And I'm now seriously wondering about re-fitting an electric start -Andy rides Brit bikes regularly: I haven't kickstarted anything for over 20 years. Yeah, of course I gave it a go after they'd left. No, I couldn't fire it up. Got it to go a couple of times, but as soon as I touched the throttle it died. Run me through the starting procedure Andy, so I can annoy the neighbours over the Christmas break -no throttle at all? Crack the throttle open as you kick? (yes, I got it on the compression stroke; yes, the fuel was on).

So- plenty to do over the Winter. I'm not planning on riding it till the Spring, but definitely want to be riding it in the Spring. So I've got a couple of months to sort out the problems.

From cold, flood carbs, no throttle and swing. Should settle into a roughly even tickover and will be throttle sensitive until the float levels lower back to normal. Should respond to gentle rev after about 15 seconds or so.
Have a great break and nice to see you.

Oh I forgot,
You don't need an electric foot. I retarded the ignition a few degrees last time so you could start it with bare feet.
Don't be afraid of it just give it a committed kick I hasn't kicked back on me once. If you are half hearted it can ignite the gas and push the piston back down the hole the wrong way so take control. It is easier to swing than a T140.

Yeah -slightly wary of it at the moment after it gave me an almighty whack on the underside of my foot last time, with the old carbs. Being a Postie, I'm on my feet all the time & was limping for days.
I'll be more assertive next time! Looking forward to annoying the neighbours with it.  ;D

Here's a very wobbly video of the bike to show the exhaust volume. Doesn't sound too bad on tickover, but it's too loud when revved -sitting at motorway speeds for an hour, for example, would give you a stonking headache.

After some words of advice from Mr Dslam, I think I've got the starting thing sussed. Don't touch the throttle at all, just kick it & it goes 1st time. When it's cold though, any movement of the throttle for the first 30 to 60 seconds & it dies again. Fine once it's warm. That'll give me time to put my helmet & gloves on though. :)

Good point............

For ref, check the photo of two differnet clutch activating arms, one has the cable mounting point nearer the fulcrum than the other.   http://www.xs650.com/threads/longer-clutch-actuator-worm-arm.21366/

Prob worth being aware that "Mikes XS" (in the states) have for sale a clutch activating arm that has the option of where the cable attaches, so there's  an easy-to-operate-but with less-lift option, or a more-difficult-to-operate-but-with-more-lift option.


Title: Re: Manky's XS650 Yamaha
Post by: Clive on December 28, 2016, 08:50:28 AM
Looking back to page 93, Andy has the gear arm with both holes in it, and currently has the cable mounted into the hole closest to the worm drive itself, therefore giving maximum travel.

Is there any further adjustment in the cable itself, Andy and is the adjusting nut on the back of the worm drive fully 'out'?

Post by: Manky Monkey on December 28, 2016, 03:49:36 PM
You're right Clive, although I'd actually forgotten that, (yes, my memory is that bad). Everything's set just as it should be, but if I pull the clutch in I can still kickstart it, so the clutch isn't disengaging. The plates only move a millimetre or so, which obviously isn't enough, & the lever's very stiff. I've just ordered a new set of clutch springs for a tenner, just in case they're heavy duty race ones. Already got a new pushrod with the correct number of new ball bearings. Other than soaking the plates in oil, I'm not sure what else I can do.
Stinkey- O.K, it's too loud for me. I want to do some serious miles on it so want it sensible -planning a ride to Belgium in June.

Kinda agree.........

I've stood next to it with the engine running, initially with mild steel pipes, and then with the current stainless pipes.

The Stainless pipes have changed the sound from the standard-XS-without-silencers noise to a much nicer note, more similar to a Triumph, but when revved it certainly ain't quiet


Maybe time to add the re-phase to the to-do list  ;D  (to quote Derek Trotter: You know it makes sence  :D )

Am I missing something or does a bike clutch work differently BUT if the bike is in gear and you pull the clutch in then you SHOULD be able to kick it over if the clutch is disngaged? Otherwise if the clutch isn't disegaged then being in gear it would try to push teh bike forward when kickstarting ( besides breaking your foot?) .

 Lack of travel to disengage? What about the handle bar size , would say using 1" bars insted aof 7/8" stop full travel ie height of pivot point compared to bar 'stop' size?

Plates are all within tolerance Terry.
Normally with the bike in neutral & the clutch lever pulled in, the kickstart would go straight down without resistance. Mine still resists.
7/8" bars, same as the originals. The lever & mount are pattern copies of the original Yam' ones Kev.

The kick-start operates through the gearbox, not the crank (like a car’s starting handle).

By having the clutch engaged, the gearbox can turn the crank, but by disengaging the clutch, all that should happen is the clutch centre rotates.

Old British bikes that have stood for a while often require the (wet) clutch to be freed-off before using the bike as the clutch plates stick together – this is done by disengaging the clutch (thus taking pressure off the plates) and repeated kicking (which initially has resistance of the engine’s compression) until the plates break free. If this isn’t done, the machine can lurch forward when first gear is selected with the cutch lever hard against the bars!!  ;)

Yup, starting routine with my old Bonnevilles was always pull the clutch lever in, kick a couple of times to free the clutch off, a couple of times with the clutch out to circulate the oil -then switch the ignition on, prime the carbs & give it an enthusiastic kick to start.

Nice to see Clive this afternoon. He very kindly came over from Andover to take a look at the charging problem. He knows one end of a wire from the other & can use a multi meter so is in the ranks of Grand Masters & Wizards as far as I'm concerned.
The wiring appears to be correct, according to the colour coding & the Earth is fine, but there's nothing registering on the meter from the alternator when the engine's running. Can't check the regulator/rectifier without power from the alternator.
So it looks like I need a new stator ring or brushes. I haven't touched either during the build so they may well have been duff since I bought the bike.
Thanks for your time Clive :)

The rear ones need to be raised up clear of the exhausts, so will bolt to tabs welded into the V of the mudguard bracket, (it'll cost about a fiver to get the bracket re-coated). Yes, the jumbo sized numberplate will be going, right after the MOT.

Andy, I trust you had on board a charged battery, as your alternator is of the type that requires external excitation via the battery/brush-gear/slip rings, to its field coil, for an output to be achieved from the alternator stator. So, charged battery, clean slip rings, and properly bedded brushes. If all this is as it should be, you, or who ever is wielding the DVM, should see 14.2v dc across the battery at all rpm above tick-over. Unlike a PMA, which does not require separate excitation, yours is a Field control system, which will work very efficiently, if all these conditions are met, ok, Morrag

Battery was charged before we started, but once running at above tickover, no increase in volts were seen, in fact it was running on battery power only, with no more than 10v seen when it was running.
No output from the alternator was observed either at any rev range.

When we finished the battery was down at 6.5v but recovering nicely.

A very rough check on field coil operation Andy, is to loosely "dangle" a thin feeler gauge adjacent to the alternator aluminium engine cover, and close to it. If the field coil is energising you will see a magnetic "pull" on the dangling feeler. Rough and ready but a reasonable indicator. Assuming that's ok, check between each pair of outgoing leads from your stator, that's the 3 yellow, or 3 white leads, and usually, & for most alternators of your type, it should give you a reading of around 1/2 ohm between each pair, & although I haven't got a specific set of resistance readings for your bike, that should be near enough! ok... Morrag. ps, if all else fails, post it down to me in a large Jiffy bag & I will sort it, ok ;D ;D ;D

Something like a 6" steel rule on a piece of string, 1/4" away from the case at around the "1/4 to..." position should be a good indicator, well that's what I use.....( no not brass, or titanium, or.... :D)

I don't do electrics ? ;D I'm building my brothers chop (1976 z900 ) on and off for many years..using some of the original loom..I had a guy do the loom for me several years back..but changed the frame since..it seems to be a simple problem ( live wire touching ?) keeps blowing a fuse..
And similar thing on my trike ? Hopefully one of our fellow monkeys is coming to my rescue?

Well, if you are blowing the same fuse each time, then you have to test the wiring/components within that circuit. For example, you might have 4 or 5 fuses in total, depending on the machine, one, usually 20A will cover the charging circuit, the others, fused at around 10A maybe, will cover front and rear lighting, another aux. such as the horn and indicators, etc. so once the particular circuit that the fuse is blowing on is identified, then start isolating a component at a time, logically, and with perseverance, all will be revealed ??? ??? ???, well, lets say usually........................ the fuse ratings and number off fuses I have selected randomly so your own wiring diag. for your particular model will have to be consulted, of course,.Morrag

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 03, 2017, 08:33:07 PM
I don't even know what a DVM is.  :P
Sat & looked at the bike for a while this afternoon. I've got quite a long To Do list now, which will involve a bit of fabrication & at least one more trip in a van with the bike to someone who can do a spot of welding for me.
So, starting at the front:

Buy & fit a green LED in place of the blue one in the speedo.
Have a look at the speedo drive -I've fitted a 90 degree drive unit intended for a car to the end of the original Yam' drive unit & I've got a feeling the plastic "cable" that fits into the original one isn't long enough to properly connect, or, being plastic, will wear very quickly. So the speedo might not work, or not for long anyway. So might need modifying with a section of old metal speedo cable.

Modify & fit the new aluminium bodied indicators I've bought. I'll drill the backs of the front ones & glue in amber lenses from a pair of Halfords dashboard warning lights as a tell-tale so I can see they're working.

Maybe change the fuel taps, as the righthand one doesn't fully close, (can't find them on Ebay now). I'd like to fit something with a Reserve position cos I know I'll forget & run the tank dry.

Pull the clutch apart & go through it all again. Everything's new, but the lever's far too stiff & the plates don't appear to be separating enough to disengage the drive. I've bought another set of springs cos they were cheap, just in case the ones fitted are super duper heavy duty ones, but it might be down to changing the lever for more leverage or something. Has to be fixed or I won't be riding anywhere.

Sort out the charging system. I've got a new set of alternator brushes on their way from the States. That might be all it is, but if not I'll buy another alternator or rectifier if I have to -again, it's going nowhere if that ain't fixed.

Buy a couple of lengths of perforated stainless tube, (if anyone sells such a thing), half the diameter of the pipes, & some big washers & make up full length baffles for the exhausts, to be wrapped in silencer wadding. I don't want to strangle the engine, but it definitely needs to be quieter for regular riding. If I start with baffles the whole length of the pipes, I can gradually shorten them till I'm happy with it.

Chase the engineer who's drilling & pinning the modified spare kickstart lever so I can get it welded up. Once fitted, it may need a flat face filed on it to clear the footpeg mounts as the current one fits close enough to have scuffed the powder coat.

Buy a modern blade type fuse box to replace the glass fuse one that's fitted & mount it to the underside of the top panel of the electrics box, under the seat. That panel's held by 3 dzus fasteners so it can be removed without tools, but the seat mounts need modifying slightly so it can be easily removed to get to the panel. If the wires to the fusebox are extended by a few inches, the panel can be taken off & flipped over to give easy access to the fuses. I'll probably fit a multi pin connector block to the fusebox too.

Cut away the lovingly made cross shaft arrangement for the rear brake, fabricated by my brother Steve, & replace it with an aftermarket Harley style master cylinder, which will fit directly behind the brake pedal with a short rod connected to a drop arm by a clevis. It'll require making new mounts & welding them to the frame. Much simpler & will have an integral reservoir, meaning I can remove the reservoir & pipework currently taking up space in the electrics box. Also means I can do away with the pedal return spring bracket under the frame, which is currently the lowest point & turns running the bike up a ramp into a van a 2 man job as it bottoms out & the bike has to be lifted part of the way. Remake the rear brake hose.

Cut the front face off the battery box & make up a new one that's removable -the idiot that designed the bike built it so that the battery can't be removed without taking the entire box out first, which has to come out from underneath the frame, involving jacking the bike up 6".

Modify the rear brake anchor arm. In it's current design the caliper could theoretically flip past the centre point under heavy braking & move around the disc. Making & welding on a new mount with a 2 bolt fixing would cure it.

Replace the rear indicators with aluminium ones. That'll require making & welding mounting tabs on the mudguard bracket to lift them clear of the exhaust. Then I'll need to find somewhere suitable to fit a reflector. I've got a pair of the current circular red glass ones, so could maybe weld a washer to either side of the mudguard mount for them to bolt through.

Nearly all the new parts will be powder-coated black & various sections of the frame will need rubbing down & spraying black.

So lots to do over the next few months, while also working on my truck.

I've bought another set of springs cos they were cheap, just in case the ones fitted are super duper heavy duty ones, but it might be down to changing the lever for more leverage or something. Has to be fixed or I won't be riding anywhere.
Before fitting the new springs, try removing 3 existing alternate springs and test the action - that way you'll get an idea of how the other components are working. It shouldn't happen as the torque setting for the springs doesn't further compress the springs, but have a look just in case (for some weird reason) they're getting coil-bound. Again, it shouldn't happen, but check the basket isn't touching the engine cover.

Sort out the charging system. I've got a new set of alternator brushes on their way from the States. That might be all it is, but if not I'll buy another alternator or rectifier if I have to -again, it's going nowhere if that ain't fixed.
 another (replacement) alternator prob won't be cheap, unless it's 40 odd years old, and they are a 'weak' point of the XS, so maybe have another ponder on the PMA?  ::)

IF you should go down the PMA route, not having a battery could be an option...

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 04, 2017, 06:14:28 PM
That's an awful lot of holes!
Hmm, my pipes are 1 5/8" diameter I think, (Have to check cos I can't remember), which is about 41mm. So I'd be looking for perforated tube of around 20mm. If I used 35mm with a single layer of exhaust wadding around it & make them as long as I could fit in the pipes, (3 feet maybe), would they make much difference to the decibel level? I don't really want to introduce excessive back pressure by reducing the bore size too much. Slit the tube & squeeze it up to about 30?
I assume those 2 stroke ones are 28mm collar size, so the perforated tube would be 20mm or less?

I would use the largest perfrated tube that will allow a layer of wadding, the longest thatt will fit. Also go for proper perforated tube, it works much better than that 2 stroke tube. I think you'll be suprised how quiet it will be, and if not quiet enough you can still couple the two together, that would halve the pulse size.
My 750 four is on a single race can, 500 odd mm long, straight through, on a 4 into 1. Its just about perfect, I reckon.

Modified the new front indicators this afternoon. I've used this type on several of my trikes & found it was handy to have a tell tale light to show they were working. Bought a pair of cheap dashboard warning lights from Halfords, then cut the heads off them to make amber lenses. Drilled the backs of the ali' units so the light from the bulbs will show through. The bodies will be powder coated black, then I'll glue the lenses in place.

So, my learned friends, I'm curious -would the spirally, screwy thing work & what effect would it have on engine running, (back pressure, pulsing etc)? Worth a go?


Title: Re: Manky's XS650 Yamaha
Post by: flc on January 06, 2017, 06:29:23 PM
I think ( so this is a guess at best) that to quieten an exhaust you have to deflect or break up the pulse, some performance back boxes I've seen cut up have two tubes at opposite sides that are not connected, ends blanked off ( usually squashed ) and the exhaust air passes from One tube to the other by the small holes/ perforations in them, so I think yes it would make less noise but you can only test it to be sure, does seem expensive unless you could make a spiral your self?


Title: Re: Manky's XS650 Yamaha
Post by: stinkey on January 06, 2017, 06:48:47 PM
Would you mount the screwy thing on bearings so it spins ? And maybe a light too ? OOH ..shiney spinney things..OOH OOH ::)


Title: Re: Manky's XS650 Yamaha
Post by: flc on January 06, 2017, 07:27:47 PM
Then it would whistle  ;D
Do it do it!
Thinking a bit more, the eBay one looks to have an inch(or so) center pipe so not sure how you would rig it?
Also I recon that whilst it may slow the flow, it won't actually break up the pulse so not giving up any noise and yes it could whistle  ;D I'd like to see the results though,
Other one is vw baffles the short exhaust end pipes are internally baffled, years ago a mate had a bonnie that ran them, I don't have a set to loan you but could ask around the vw crowd?

You can get some unexpected effects - a lodger here years ago had a Kerker exhaust like this on his V-Max.  It made a hell of a noise when started up - we used to call it The Beast.  He didn't like the look of it so he shortened the can by about half - it looked bloody gorgeous but the amazing thing was, it was quite a bit quieter, although it still had the V-Max growl!

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 11, 2017, 05:33:20 PM
Really fallen out of love with this lately.
Seems like every time I think it's finally almost done, it takes several very large steps backwards & I have to throw yet another bucketful of money at it. Because it's in a different garage to my truck, on the other side of town, it's been easy to just ignore it & concentrate on the truck instead. I need to crack on with it though or it'll just languish there for ever.
Didn't have enough time after work today to get anything achieved in the truck garage, so I've been sat, taking a long look at the bike. I think I need to take the plunge & pull it apart -when it's in one piece I'm loathe to start on it.
The righthand engine casing needs to come off, (draining just the oil that it loses when it's on the sidestand -not really worth changing the sump filter yet), then I can tackle the clutch again. With all new parts, it can't be a big problem -I'm not putting the casing back on till it's fixed.
I've got new alternator brushes so can take the other casing off & fit those, but can't run the engine to check the output again without charging the battery first. That involves taking the battery out to charge at home, (no power supply in the garage). If I'm doing that, I may as well take the box out & modify the front, for easier access in future.
I've ordered a couple of lengths of the smallest bore perforated tube I could find & some washers to make end collars with, so will have a go at the exhaust baffles when it arrives. The pipes are 41mm I/d & the tube's about 32mm.
I bought an aftermarket Harley style brake cylinder, intending to take the back brake set-up apart & simplify it, but looking at it, it'll be a major job to do -& the new cylinder won't fit anywhere I thought it might -so that's going in the spares box & I'll stick with the set-up I've got.
It'll probably be the weekend now before I get enough daylight to make a start, but the sooner I do, the sooner it'll be finally finished -please God, no more set backs.  :(

Mr M, please don't take this as a critique in any way. Your builds are excellent, but the logistics sometimes get in the way, i.e you get a little pre occupied with getting things powder coated, and the like, before the bugs have been sorted, if you get my drift. So, its an ongoing project, not a build that's emerged from the factory gates and onto the dealers forecourt, ergo, stop beating yourself up about it, work though the outstanding probs. in your usual way, and then, one day, & when to your liking, strip and paint/polish/powder coat "at will" ;D ;D ;D I speak as one who has made most, if not all, of those 'stumbles!' ??? so deep breath and....Morrag

Yep, that puts things in perspective doesn't it. They're only vehicles at the end of the day. There's more important things to worry about. Good luck Mr S.
Spent a little while messing about with body filler on my truck this afternoon before a flurry of snow outside made it too cold to carry on. Stopped off at the bike garage again on the way home though & took another look at the bike. I'm going to put aside Sunday this week to get the necessary bits stripped down, ready to sort out.
I'm tempted to forget fitting the alternator brushes & just buy a Permanent Magnet Alternator as recommended by several here. Local guy Tom has one on his XS project & it appeared to be a very simple straight forward fit. I'd like to keep the battery though, partly cos it's a useful back-up for lights etc & as a Get You Home power feed if the alternator packs up, & partly cos I like the look of the battery box & don't want a big space left if I get rid of it! (yes, I've thought about putting a tool box there, mounting a brake cylinder there etc, but would still prefer a battery. Anyone know if the PMA set-up will support a battery?

So, Tom's got this system:

http://www.electrexworld.co.uk/cgi-bin/sh000001.pl?WD=xs650&PN=STK-467D_-_Stator_Kit%2ehtml#SID=770?aSTK_2d467D

I think that fires from the crank, rather than the top end as my electronic ignition does. So I'd have to remove the Boyer Bransden set-up I've got. Mr Dslam's altered the timing slightly to get the best from it, so would fitting this screw up my nicely running motor?
I really don't understand electrics -if I go this route I may be looking for a, (paid), volunteer to splice it into my existing wiring! (my Post Office Christmas bonus & this week's P.O employee shares dividend will cover most of the cost of the kit).

Post by: tom_prs on January 12, 2017, 10:37:10 PM
Yep thats the one, I thought it was pretty reasonably priced compared to other PMA kits out there.

Wiring should be fairly straight forward; the kit comes pre-wired, includes the reg/rec and even to the spark leads, so once you've removed your existing Boyer kit/coils it should just be a case of bolting the kit on and linking up the 12v from the PMA to the fuse/battery. More than happy to lend a hand if needed!

The drawback of this system is that adjusting the timing isn't as easy. As you mentioned it fires from the crank, which means pulling the rotor to make adjustments - not difficult, just not as easy as points/boyer kits.

Yes it will charge your battery. Indeed, basically, the only difference is in excitation, although the PMA set up will require a Reg./rectifier unit. Personally, and as you have the brushes, why not install them and check your output, as "Mr OEM" did not install a system that doesn't work! and with your very reasonable electrical loading requirement, you will be fine with what you have, assuming your alternator is not faulty, of course, gwan,try it, you know it makes sense, and save yourself some dosh!! :D :D....

Title: Re: Manky's XS650 Yamaha
Post by: Tony oily bike on January 13, 2017, 11:12:57 AM
Me thinks Morrag has a point – for the sake of fitting the brushes, a ‘responsible adult’ with a multimeter will let you know if the current (pun!!) alternator is working.
If it is, then the rectifier / regulator function can be checked to. It may be that the system is hunky dory (albeit 40 years old and a considered weak spot of the XS......), in which case you'll have a smooth-running, electrically-charging, somewhat-loud bike  - just leaves the pipes (old system for MoT?) the torque arm, and indicator/tail lamps that don’t blow for the MoT............ then have an MoT'd bike which can have the "desirable" bits added/modded to suit. ;)  That's assuming I'm right in thinking the clutch doesn't really matter for the Mot?  ::)

The PMA route:
Tom’s system is a combined ignition/PMA, so has a timing trigger built in.
Junkyard Frog is currently running a nice (and already set up by Dslam) cam-timed Boyer electronic system, so doesn’t really need a PMA system with the trigger built in.
I’m assuming a combined ignition/PMA could be fitted, ignoring it’s timing trigger bits n bobs, and keeping Andy’ easy-to-adjust Boyer electronic system??

Although it may not matter, the combined system is advertised as having a single phase 65W alternator. Units from Heiden/Mikes XS have a 180W or 200W (prob 3 phase?) units.

Heiden’s system (without the timing trigger) is advertised at 270Euro (appx £236), and has a 180W alternator.

Well, on the question of age/reliability, my '65 Triumph runs its original single phase alternator, and whilst it is a PMA system, is never the less even older, and works fine. The separately excited system used on your Yamaha is well tried and tested method used on many, many, car alternators over the years, and whilst if starting from scratch it would make sense to use a PMA set up , why change that which may not be broken. The 65w alternator is more commonly intended for 'Comp.' type bikes with direct fired ignition via a capacitor, and not reliant on a charged battery, whereas the 200w system will certainly be 3 phase, charging a battery via a combined Rectifier/Reg. unit of a type very common to  so many Japanese machines, and is more suitable where the electrical loads of modern road bikes are experienced, Morrag

O.K, O.K! :) I'm not rushing out & buying anything -yet, just exploring the possibilities. Yes, I'll fit the brushes first, but don't own a meter & wouldn't know how to use it anyway. I'll take the battery out & charge it, (not a 5 minute job, which is why I need to modify it's box), & have the Pop battery I could presumably use to start it for testing. How would you test the rectum frier?

Post by: Manky Monkey on January 15, 2017, 06:51:48 PM
Mr BayChimp dropped by the garage today to give me the much needed kick up the bum to start work on the bike again. Thanks Bob.
He'd been checking out how-to videos on YouTube & we had a Haynes manual. So we took the righthand casing off & had a look at the clutch.
So the lever was very stiff & moved the plates this far -about the thickness of the tabs around the edge of the cork faced friction plates.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 15, 2017, 07:00:19 PM
We counted the plates -6 friction plates & 5 plain steel plates. That's right I think, (some models had more).
At the back of the clutch basket was another steel plate though. Now I knew this was there because I'd tried to remove it when I took the clutch out to replace the gearshift mechanism behind it, but couldn't shift it from the back of the drum, so left it alone. It was definitely another plain steel plate, with the teeth around the inside edge that locate on the inner drum. All Bob's videos he'd watched, plus the manual said there should be a cork friction plate at the back & front of the stack. No mention of a steel plate at the back.
It was wedged pretty damned firmly in the back of the basket & after some initial prodding we decided to use good ol' fashioned brute force to get it out. You can see a few rust spots on the locating teeth, which makes me wonder if it's an extra ring from an older set. If I have to, I can buy these new.
That'll be buggered now then.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 15, 2017, 07:04:26 PM
Behind that plate was a plain steel ring. No locating teeth -looks like a spacer. The inner drum has a recess machined around the back edge, which is what the toothed ring was wedged into. The plain one doesn't seem to locate into that, just sits over it. Does that make sense so far?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 15, 2017, 07:08:33 PM
All the plates that came out. These are the new cork faced friction plates I fitted when I took the clutch assembly off to replace the gearshift mechanism. I was going to soak them in oil, but they looked pretty well oiled so I won't bother.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 15, 2017, 07:14:48 PM
The problem had been that the clutch wouldn't disengage, presumably because the plates weren't separating enough.
We seemed to have one plate too many, that wasn't mentioned anywhere in our guides. Would taking it out fix the problem?
I bought new clutch springs the other day, wondering if someone had fitted heavy duty race type ones. All the Ebay ads I read were for heavy duty ones, except one, so I bought those. When we took the clutch apart we tried removing 3 springs first, as Tony suggested, to see if the lever was easier to operate. It was.
As you can see, the new springs are shorter than the old blue ones. So which are correct? Couldn't really tell just by squeezing them, whether the new ones were any softer or not. One of the YouTube videos said these should be torqued up to 6 psi. I'll check that in the manual cos it doesn't sound right to me. For now we've just wound the spring bolts in finger tight.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 15, 2017, 07:31:31 PM
So after an hour or so of stripping & rebuilding, we now have the opposite problem.
The clutch lever feels more or less the same, (still too stiff), but the clutch is engaged all the time. Putting the engine in gear & rocking the bike back & forth with the clutch lever out, it's free wheeling. We did have a point, before we temporarily refitted the casing, when it seemed to be right & you could hear the compression of the engine turning over when it was rocked in gear, but that only lasted a few seconds before it seemed to free off & run free, so was presumably the oily friction plates unsticking themselves.
We haven't altered the pushrod adjustment, or either end of the cable & there's no freeplay at the lever, so it may now be just a matter of adjustment until it engages drive as the lever's let out. As I said, the springs aren't torqued down, but are done up finger tight with a screwdriver, so pulling them up tighter may make a difference. Anyone know the correct torque setting for those?
The clutch was dragging. We've removed one plain steel plate & now it's slipping.

Is that progress? Not sure, but having a second opinion helped & we're pretty sure everything's correct. I bought the bike from a car trader, who'd taken it in part exchange for a car. He didn't know anything about bikes so said his son had put it together enough to sell it. It came with a box of assorted parts, some of which weren't even XS. I assumed he'd just bolted the bike together & not worked on the engine cos it seems to be in pretty good shape internally, but it's entirely possible he put the clutch in & added an extra plate from the spare parts. Any opinions? Should that plain plate have been there, (in which case I'll buy another), or not? Does it sound like just adjustment now to fix it, including torqueing up the springs, or is there anything else we need to try?

Some people have families & Bob had to head home for Sunday lunch, so I pottered on for a while longer until my rechargeable worklamp ran out of charge.
I removed the front LED indicators, which involved cutting the righthand one off cos some idiot had decided it'd be cool to run the brake hose through the hole in the middle of it & I wasn't going to disconnect it & have to rebleed the brake. Temporarily bolted the new ones on. The bodies are polished aluminium but they'll be powder coated black so they're slightly less conspicuous. I know they're quite big, but I'm quite happy with them. I'd rather be seen, particularly in the dark, than dead.

From the riding position the rear facing lenses I fitted in them will let me know if I forget to turn them off as the switch isn't self cancelling, (I've got a feeling it might have to be for the MSVA test when I do it). Fortunately they don't block my view of the speedo either.

Post by: Manky Monkey on January 15, 2017, 07:47:30 PM
Before Bob left he gave me a hand to lean the bike over as far as we could so I could remove the battery box from underneath. There isn't enough room between the top of the battery & the underside of the electrics box to take it out from the top & not enough clearance between the bottom of the frame & the ground to drop the whole box out from underneath, (unless you have a mate to hand to lay the bike over far enough). Very poor design on somebody's part.
So I hacksawed the front face off the box & will fit a bolt-on front panel, so the battery can be taken out from the side of the bike.
Now I need to find an offcut of 2mm steel plate & a folder to fold the edges.
Thanks for your help today Bob  ;)

From the info.

Earlier models in this year range used 7&6 respectively, it appears. You should have pushrod, ball, second pushrod, another ball, & mushroom. Start and finish with a friction plate, and that's it. Some early XS1 & XS2 versions use plain cushion rings as well, but don't seem applicable to your XS 650. Hope this may be of some assistance Mr. M.... ???  Morrag

Have you seen the following video ?
Pay particular interest to the section from 8 min 20 sec to 10 min 25 sec where he says the torque is 6 psi ?
Of course he meant ft/lb  but then later on at 13 min to 14 min where he corrects himsel to ft/lb but cannot make up his mind whether it is 6 or 7 ft/lb .
At 21 min he is going to demonstrate adjusting the clutch .
Personally I use a box spanner to nip the lock nut up rather than using an ordinary spanner as he does .
At 29 min he says that the engine cover allen head bolts are also torqued to 7 ft/lb .

So I've got the correct number of plates for the year of manufacture then. The pushrod's a one piece aftermarket one, but exactly the same combined length as the earlier 2 piece ones.
Yeah, we watched that video on my phone in the garage this morning Tony, (ain't technology wonderful). Not really telling us anything we haven't already done though.
Cushion rings -that's the plain ring we found at the back of the clutch basket?

Andy after having another look at some exploded diagrams,of which there seems to be many. Not surprising as the model crosses so many years.Its difficult to know which you have.And the manual is not very helpful
It looks like the 1980 model should have two plain plates and one toothed plate and what looks like a large circlip that goes on first at the back of the basket,then the six friction plates and steel ones.See the diagram that Tony posted for the 1980 model. We will have to have a play another day and see if we can sort it. I found it interesting as I have never looked inside one of those before.

Mine's a 1980 XS650 SE, (the American market model).
So it looks like it should have the plate we mangled, plus another, plus a circlip the same sort of diameter as the clutch plates -none of which we have & it seems none of which are still available. Will the clutch still work without them? If some models had them & some didn't, I tempted to try torqueing the springs down & just playing with the adjustment. If we can get it working I'll leave it well alone after that.
The old springs that came out measure around 42mm open, so presumably the new ones, which are shorter, are about the right length.


Title: Re: Manky's XS650 Yamaha
Post by: morrag on January 16, 2017, 04:30:11 PM
Andy, your model will have the clutch centre shock absorber, which consists of a spring seat, conical spring, inner plain plate, which are not the same as plain clutch plates, it appears, and finally a retaining wire circlip. Dispensing with these bits  would I feel, create the sort of clearance probs. you appear to have, so therefore if possible you should aim to replace. Failing that rebuild it as per the earlier XS models, got to be worth a try!! ;D...Morrag


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 16, 2017, 05:04:56 PM
O.K, so it would appear we've buggered the one part I can't find a replacement for -the special first steel plate, (I assumed they were the same as the rest of the steel ones as they look the same & it felt like the same thickness). I'm guessing it was so difficult to remove because there's a retaining clip we couldn't see tucked down into the groove in the back of the clutch basket. As you say Morrag, that appears to be a sprung steel wire & is available from Mikes XS in the States.
So I'm getting confused -if we remove the wire & the plain steel plate, plus the spring assembly, (not actually sure where that is), do I need to fit one more steel & one more friction plate in their place & is it as simple as that or am I going to need a whole new clutch basket as well? This is why I'm getting so disheartened with this bloody thing.  :(


Title: Re: Manky's XS650 Yamaha
Post by: morrag on January 16, 2017, 07:26:47 PM
Well, firstly, I think that's exactly what's happened, and indeed why you had to butcher the original 1st steel plate. The info. says that the inner steel plate should not be confused with the plain clutch plates so I assume its a different thickness, however, in lieu of the original bits, I would drop a spare plain plate onto the clutch hub, then follow with 6 friction and 5 plain, alternating of course, and ending with a friction plate. You will have to leave the spring seat and conical spring/circlip of the original set up out, and as such run without a clutch shock absorber. If you find that the clutch requires packing out to grip, then add a futher plate each of friction and plain, if there's room. It's really suck it and see time. Obviously,try and remove the large circlip replacing the plates. Give a try.....Morrag


Title: Re: Manky's XS650 Yamaha
Post by: Baychimp on January 16, 2017, 08:13:58 PM
Andy the reason the last plate was so hard to get off was the guy that put it back together before you bought it left two pieces of the puzzle out. So it moved to far back and got jammed. The plates are a different sizes, the anti loading plate is 1.6mm and the others are 1.4mm.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 16, 2017, 09:03:57 PM
I'll have another look at it later this week.
Just been shopping for a couple of plain steel plates on Ebay & ended up buying this complete clutch assembly instead. It looks well used but might yield some parts or go in as a complete replacement, using my new friction plates & springs.
Never had problems like this before with any of my previous XSs. I'll be so glad to get this thing finished. Never, ever again.

My day off today so I spent some time tinkering with other stuff while I regain the enthusiasm to have another go at the clutch. Cut a couple of triangular indicator mounts from the panel I cut off the battery box. Also saved the threaded sections from that panel that the leather battery retaining strap attaches to.
New clutch centre nut & locking tab washer arrived in the Post from Yambits. Also received some stainless steel shelf brackets, £1.50 for 5 with free postage all the way from China -how do they make that pay? They're decent stainless too cos they work hardened when I opened the holes out & buggered my drill bit. I was going to make some mounting tabs for the reflectors, but for that price, why bother making them?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 18, 2017, 08:29:19 PM
These are American bicycle reflectors, (copies of vintage 50s style ones), in red glass. They come in other colours too by the way. I had one bolted through the hole in one of the previous circular indicators. Those flashers were quite quirky, but very delicate & wouldn't have lasted long on the bike, so I'm going for these more robust aluminium ones instead. Using the little stainless brackets, I can hang one reflector under each indicator. I'll powder coat everything black eventually.

Spare/replacement clutch arrived today.


Title: Re: Manky's XS650 Yamaha
Post by: Tony oily bike on January 22, 2017, 01:23:57 PM
I'll have another look at it later this week.
Just been shopping for a couple of plain steel plates on Ebay & ended up buying this complete clutch assembly instead. It looks well used but might yield some parts or go in as a complete replacement, using my new friction plates & springs.
Never had problems like this before with any of my previous XSs. I'll be so glad to get this thing finished. Never, ever again.

This may or not be of use, but just in case.............

Managed to take a look at an American Cylmer manual (special edition UK) for the 1970-78 650 twins (printed 1979), and in particular the section on pages 80 & 81 relating to the clutch.

The exploded diagram on p80 is that of a 6 friction, 5 steel plate clutch.

It states “Note that the friction plates are alternated with the metal clutch plates but that the friction plates are not all identical. There are 4 fibre-backed plates and 2 aluminium-backed plates. Two fibre-backed plates are installed first, followed by the the 2 aluminium-backed plates. There will be a metal clutch plate between every set of friction plates."

It also mentions the flatness of the plates, and states  "if a 0.2mm feeler gauge can be inserted under a plate when on a surface-plate or sheet of plate glass, it should be replaced."

Never heard of one with ali plates in it, but then, didn't know about the ones with an extra steel plate at the back of the basket until we destroyed one.
Should've had another go a the clutch over the weekend, but to be honest, the recent list of yet more jobs to do & in particular the clutch that defies all attempts to fix it have really dampened my enthusiasm. Still want to be riding it in the Spring, but struggling to find the fun in it at the moment. I enjoy being creative but I'm not a natural mechanic & the nitty gritty of getting the damn things to actually work once they're built isn't my thing.
Been a sunny but very cold day here today, so I worked on my truck instead. Promise I'll get back to this soon.

I know how you feel mate. I was working on the Pop today outside my lock-up garage -when I rolled it back inside this evening there was ice forming on the roof & I had to scrape the windscreen of my car before I drove home. Early night now for me to warm up, ready to walk the streets at work again in the morning.

Mr BayChimp called at the garage again this afternoon & we had another look at the bike.
The replacement clutch I picked up on Ebay appears to be a pre '79 one. It doesn't have the sprung shock absorber arrangement that the original had, but looks like we can fit it in place of the old one.
So we stripped the original off the engine, leaving the outside basket in place, then slotted on the earlier inner basket. Locking tab washer & new hub nut ...bugger, the tab washer's different. The later one has ears that locate in slots in the inner basket. No slots in the replacement, early inner basket.
So things came to a halt yet again. I've just checked a few websites & it seems the early models used a domed "Belleville" washer instead of a tab washer -torqueing the centre nut down spreads the washer & locks it in place. When we took the existing clutch off it had both -a tab washer with the slightly domed one on top. I've just ordered a new one from YamBits though -don't want to risk re-using an old one.
So still no further forward, but plodding on slowly.

A diagram of the early clutch set-up I bought from Ebay. Think it might be missing the plain washer behind the "conical Spring" or "Belleville" washer, but otherwise, it's the same.

Post by: Manky Monkey on January 27, 2017, 04:41:30 PM
Just a simple flat washer behind the locking one Bobbi. I picked up a stainless one from the local tool shop this afternoon.
They changed the clutch set-up several times while the model was in production, but then I guess every bike or car gets updated almost every year now doesn't it. What gets me is I've owned 5 or 6 of these over the years. I know my memory really is shot to bits these days, but I'm sure I just bolted them together & they worked -none of the faffing about I've had with this one. It really does seem to be fighting me every step of the way.

Mr M this may be relevant, or not!, but when installing the GL 500 motor in my 3 Wheeler I decided to treat it to a set of new clutch plates, which were after market 'jobbies' and cost about £25 I recall. Now they looked fine, but would they free, would they buggery! so out they came and originals re-installed and all was well. The after market stuff is not, I believe, made to the original tolerances, hence the problem. No doubt in use with a little judicious "slipping" they might have bedded in, but for now they can stay on the shelf! >:( >:(...Morrag

Perforated stainless tube for the exhaust baffles finally arrived today -the 2nd lot after the 1st apparently went astray in the Post -bloody Posties  :P
This was the smallest diameter I could find on Ebay & is 32mm ish. The pipes are 41mm ish, so there won't be much room for wadding, but I'm hoping I can get one wrap around it, (need to buy the wadding now). I don't want to choke the engine by reducing the diameter too much, so will see how this works out. I bought 4 lengths so could extend them by another 100mm or so to completely fill the exhaust & might try that first, so I can shorten them to suit if needed.
I'd previously bought some stainless stepped pipe reducers to use as collars at each end. The large end's actually exactly the same O/D as the pipes though, so they'll need slitting & pinching in a little until they slide inside. They'll be held with a 6mm captive nut welded into the back end.
At the moment I've got 300mm long conical perforated tube baffles, so whether these 500mm long straight ones with some light wadding will be any better I've no idea. We'll find out.

Back to the bike again today, with my trusty sidekick, BayChimp, for added enthusiasm.  :)
I was tinkering with the exhaust baffles when he arrived at the garage, so I left him to remove the engine casing & fit the replacement clutch centre, (from an early model XS). As we had 2 sets of clutch plates, we decided to go with the older option of 7 friction & 6 steel, so used the newer ones, plus one of each taken from the Ebay clutch & put into the middle of the pack. We backed off the adjusting screw on the pushrod & slackened the cable, then re-set it all.
Result- we appear to have a working clutch, though we're being cautious about celebrating until the engine's running again & we can properly check it. Think it still needs some cable adjustment, but with the back wheel off the ground & in 3rd gear, the wheel spins with the clutch in & turns the engine over with the clutch out -so seems to be doing what it should. Hurrah -maybe.
The lever still feels a little stiff, but it's a long time since I've ridden an XS & I can't remember how they felt. It may ease off with some use or adjustment. Absolutely no reason why the other clutch didn't work, but it just didn't.

While I nipped across town to fetch some gasket sealant from my other garage, Bob, (BayChimp), tackled the alternator brushes.
Looks like he may have found the charging problem. One of the brush wires had come adrift from it's mounting plate. The new ones I bought are supposed to be universal & fit either side of the housing, but don't appear to. Fortunately the broken one was the same as the new ones, so we fitted one new & one, (still intact), old one with plenty of life left in it's brush. Now I need to charge the battery -yes, I forgot to do it -so we can start it up again to check the charging. I've still got Mr Olds' multimeter, left behind when he was working on my truck's wiring, but haven't got a clue how to use it to check the battery's charging.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 03, 2017, 07:15:36 PM
I've really had trouble working up the enthusiasm to work on this thing lately, so big thanks to Bob for giving up his afternoon to give me the push I needed.  ;)
After he'd left I got back to the exhaust baffles. I've gone with the longest length of perforated tube I can fit in the pipes, which is 30". That means welding 2 sections together. I've also cut down the reducing sleeves to form plain collars at each end. Had to slit them down the side & pinch them in until they fitted the pipes. I've already ordered some basic baffle wadding from Ebay, which comes with stainless cable ties to hold it in place around the tube. Just hope there's enough room between the pipe & the baffles to use it. Oh yeah -the missing parcel containing the first lot of perforated tube turned up today. Seems it had been left next door, tucked in front of the owner's car. He's in his 90s & very unwell so hasn't used the car for a long time. The parcel only came to light when his daughter put the car in his garage for him this morning. The tube was posted a month ago.
I had a few errands to do later this afternoon, so nipped over to see Leia the welder in Berkshire & left the sections with her for stainless welding. Glad I did cos her Dad was there. He used to own the company & handed it to his daughter when he retired to France. He's over for a holiday & I hadn't seen him for years.

So baffles underway. Charging problem hopefully fixed. Clutch hopefully fixed.
I've got to make a new front panel & mounts for the battery box, get the rear indicator mounts welded to the mudguard strut, wire them in & also wire in the new fusebox, then get a few bits re powder-coated. I think I'm going to leave the anchor arm on the rear brake caliper as it is for now & also leave the rear brake pedal set-up well alone. Needs a new LED in the speedo, just cos it's blue & I'd like green & the tank paintwork has a run & a couple of specks of grit in it that need sanding out & polishing. Think that's about it.
I'll charge the battery over the weekend & we can try firing it up again early next week. What could possibly go wrong?  :P

Dashed over to Berkshire in the first snow flurry of the Winter, after work this afternoon. The welding shop owned by Leia, (named after a certain Princess in a Galaxy far, far away), closes early on Fridays & she'd rung to say my baffles were ready. They shut at 4.45 & I arrived at 4.44
A tidy job -& they appear to fit too, which is nice. The white stuff's the wadding. I'll only have room for a few millimetres of it around the perforated baffles, but figure some's better than none.

As I was leaving the welder's, Scott the engineer, (one time forum member Captain SaddleBags), rang to say my kickstart lever was done & he'd be at the workshop for a while longer before taking a few days off. So I had to dash back to Hampshire in the evening rush hour to reach him before he went home.
Nice job. He's drilled the 2 halves of the pedal & pinned them together, then cross drilled them, so a bead of weld can be run around the middle & the ends of the pin can be button welded too. Belt n braces cos I don't want to jump on the lever & have it snap off.

Old, standard pedal, powder coated black & replacement, modified one, which will also be coated black.

Had a weekend off from garage stuff to celebrate my birthday -I declared a national holiday for it. Didn't you get the memo?
So just nipped into the bike garage today to measure for the mounting holes for the new baffles. I passed lots of Falafel shops in London yesterday, so these are now my exhaust balaffles. The black sooty one's the previous attempt at quietening. 12"" long perforated cone. New ones are 30" long straight & will be wrapped in a thin layer of wadding, if I can fit it in the pipe. If that doesn't knock the edge off the noise, nothing will. Just concerned it might take the edge off the performance too.
I had an afternoon out after this, walking around all day without realising I had a huge soot smudge on my nose. D'oh -never wear a balaffle as a comedy nose, especially when you're on your own in the garage.

New, modified kickstart tried in place. Still needs welding, but I think it looks O.K, (I was worried it'd look enormous & a bit odd). Should make kicking it more comfortable. I may have to shave a flat on one edge of the arm cos the previous one fouled ever so slightly on the footrest bolts, just enough to scrape the powder-coating off.
I spoke to Tony the engraver on FaceBook & mentioned that the black had worn off some areas of the casings. Apparently it's etching ink, but he has some much better stuff now -Just bung 'em back in the Post to me & I'll re-do them. He lives in Spain. With my luck they'd disappear in transit & never be seen again.

This lever's off an earlier model & tucks in tighter to the engine, which fortunately means it follows the line of the frame rails quite nicely, almost like it was intended rather than entirely accidental.

Kickstart suits the bike really well, another individual touch to a very neat looking XS.

Re the engraving ink – as opposed to tempting fate and having the cases lost in transit before you even get to ride the bike, how about suggesting your engraver sends you some ink, or maybe send the cases at the end of the year when the bikes off the road.

The bikes soooooo close to being on the road, it’ll be shame to postpone its riding debut.......  get your motor runnin’, head out on the highway  ;)

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 14, 2017, 04:55:23 PM
Yeah I think sending 'em back's asking for trouble really. I'd be heartbroken to lose them & it might take several months of faffing about to get them there & back, just for 5 minute's of work. Presumably you can buy etching ink over here. I've been tempted to try rubbing some black paint into it, but knew I'd probably bugger it up. The engraving looks fine on it's own, but the black background just really makes it stand out.
Cold & dark here today, so no progress to report.

Yeah Dave, (Mr Olds), will undoubtedly know -he's probably built his own printing press at some point & mixed his own ink  ;D
I'm hoping to ride this to the Flanders Chopper Bash in Belgium in June. Maybe I can convince Tony the engraver he really wants to go too, & should bring his ink with him.
Exhaust balaffles drilled for the single mounting bolt at the back end & the welds flushed off a little till they slide nicely into the pipes.
This was the smallest bore perforated stainless tube I could find. It's about 2/3 the bore of the pipe, so only 3 or 4mm gap around it for wadding, but they run the full length of the pipes. No idea if that'll actually achieve much, but there's one way to find out.


Title: Re: Manky's XS650 Yamaha

Birchwood Casey do a black aluminium stain. Should be available from most gunsmiths (Dave in Whitchurch) or on line,but I have never tried it myself so can't comment on how easy it is to use etc. but their cold bluing is quite good. Might have to be carefull about application. Think I'd go with using black permanent marker ink. On metals it adheres well, assuming no oil contamination, but can be polished off on areas that you don't want it.
Oh, and no I haven't yet built a printing press, but I have mixed my own inks for calligraphy and to make stains for furniture restoration. Nothing suitable for use on aluminium though.

I don't see how wadding outside the tubes will add any restriction? Probably reduce it..

If you reduce the pipe diameter by a third with perf pipe you introduce an interruption to the natural flow of the gasses changing direction and flow rates, in the process reducing the db's coming out of the end of the pipe. Introduce wadding you restrict the pipe fully by a third. The wadding absorbs sound well but gas cannot pass through it without slowing it and the surrounding gasses down dramatically causing back pressure back up the pipe reducing efficiency............


Title: Re: Manky's XS650 Yamaha
Post by: Olds on February 17, 2017, 09:11:32 AM
Actually it's worse than that. Flow rate through a pipe is determined by pressure and cross sectional area. Reducing the diameter by a third, reduces the cross section area by more that a half !

I'll give it a go over the weekend. Got the rear mudguard strut off at the moment & numberplate mount hanging loose, so can't really ride it, but will try & video it with just the baffles in place.

Right. My day off today so I was running about, picking parts up from welders & dropping them off at powder coaters, but got back in time to fire the bike up this afternoon.
If I remember right, when my Pop was tested the decibel meter was placed 500mm from the end of the exhaust & at 45 degrees to it, (whichever side was furthest from the bodywork). I've downloaded a sound meter app' on my phone, so used that. Didn't have a tape measure to hand when I started the bike up, so used one of the baffles as a measuring stick. They're 30" long, so about 700mm.
Couldn't measure it with the throttle open cos I couldn't do that & hold the phone at the same time, but on tickover:

without baffles- 85db.
with baffles- 75db.

So 30" of straight perforated tube, about 3/4 the diameter of the pipe, has knocked 10 decibels off. Not sure if that's enough or not. Couldn't really gauge what it sounded like on open throttle cos when I blipped the throttle with the baffles in, it hesitated & coughed back through the carbs a couple of times. Mr 'Slam, what does that mean? Too rich? How do I adjust that out?

I also need to check whether the alternator's charging now. Mr Olds left his multimeter with me last time he was here, so if you don't mind Dave, I'll use it, but have no idea how to set it up. How do I set this to check the battery's charging & what should it read?


Title: Re: Manky's XS650 Yamaha
Post by: Sid_Vicious on February 22, 2017, 12:58:03 AM
If not mistaken it's just to turn it on now and holding the leads onto the batteries terminals now red on + and black on earth - if regulator rectifier works it should show about 14-14,5 volts when running and around 12-13,5 on only battery. The multimeter is already set to 20 volt dc as far as I can see in the picture.

Post by: flc on February 22, 2017, 07:17:18 AM
I agree , hesitation and poping through carbs Is a sign it's weak, I'd look to increase the pilot jets by around a fifth, try to find what sizes are available and go from there, rolling road/dyno would be best but costly, or colour tune kits work well , or good old trial and error, allens carbs in Nottingham usually have all the bits. I like tuning carbs four cylinder bikes can be a pain ,4x everything can get expensive

By all means use the meter Andy. Yep Sid is right. Just turn it on (yellow button) and measure the volts at the battery. Doesn't even matter if you get the leads the wrong way round, as it'll just show the volts as a negative value.

The bikes needs to warm up before worrying about spitting back .That's a very good drop at tickover .


Title: Re: Manky's XS650 Yamaha
Post by: the coppersmith on February 22, 2017, 01:22:36 PM
agree with Kapri, warm it up first. Decibel reading is OK but not conclusive until it is sat at half throttle.


Title: Re: Manky's XS650 Yamaha
Post by: Dslam on February 22, 2017, 02:21:22 PM
Sounds lean to me. Does it spit back when you begin to lift the throttle on (both cylinders) or at tickover. It maybe the throttle cutaway is no longer optimum. You could try raising the needles one notch to see.
I expected it to richen up as apposed to lean out with the baffles in. Maybe the longer baffles help the airflow. Have a look at the plugs and see what colour they are. Milky coffee is where you should be. Too much milk too lean. Not enough milk too rich.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 22, 2017, 03:33:01 PM
See, this is why I don't play with carbs!
Because the baffles have a collar at each end, which fit snugly inside the pipe diameter, I was concerned the gases on the outside of the perforated tube, between it & the pipe, would get "trapped" at the back end & cause back pressure. I need that rear collar though cos that's where they're bolted in.
The carbs spit when I blip the throttle.
It's an odd starting procedure. No chokes fitted, so just "tickle" the carbs to fill the floatbowls then kick. If you touch the throttle at all for the first minute or so it'll die. The natural inclination if it starts to falter is to open the throttle, but you can't. So just kick it over & leave it alone. If it stalls, kick it again. Once it's warm, it'll start first kick every time. So yes, the motor was warm.

So next time, give it 5 minutes to properly warm up & if it still spits back, try lifting the needles a notch Andy?

The new kickstart pedal's at the powder coaters Archie. Should have it back at the end of the week.  ;)


Title: Re: Manky's XS650 Yamaha
Post by: Dslam on February 22, 2017, 03:53:35 PM
Yes mate, Lift the needles a notch. This may screw up the carburation up the range but can indicate if the throttle cutaway is the issue which I suspect. When you reassemble make sure the slides are still lifting equally.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on February 22, 2017, 05:36:16 PM
Alright, in my garage & I've just fired it up again, (minus the baffles for now). The Meter's reading 12.7 when the engine's running, (sidelight & tail light are wired into the ignition switch so they're on all the time). Revving it doesn't change the reading. Switched it off & now the Meter's showing 13.

The marvels of modern technology! Wobbly video of the bike a few minutes ago.
Needles raised one notch, (now on bottom notch).
Plugs are sooty. Dry, but sooty black.
Didn't have a wire brush to clean them so wiped them with a cloth & put them back in.
Baffles are just pushed in loose for now & vibrate out when it's revved! Seems to be picking up cleaner now.
For some reason there now seems to be more top end noise than before. Sounds cam chainy. Not horrendous, but I ought to check it's adjustment while I remember.

Cam chain adjustment correct. Also noticed the indicator switch was on, although there's no flashers fitted at the moment, (they're at the powder coaters). Don't know if that would show as a draw on the battery, along with the lights?


Title: Re: Manky's XS650 Yamaha
Post by: Dslam on February 22, 2017, 07:24:39 PM
A bit difficult to ascertain whats what on the vid. The top end noise may be down to the uneven tickover. I suggest you get the baffles bolted in and get it MOT'd and we will have another look at the carbs to compensate for the baffles.
The charging is a misnomer coz it aint!
The discharge is down to the bike being run and the battery is recovering after it is switched off. It is possible that the battery is fully charged and the regulator is dumping the charge but I am no expert where alternators are concerned. I'm more of a dynamo/Magneto kind of guy.

Post by: morrag on February 22, 2017, 08:41:48 PM
Mr M you are in obviously good hands with Mr Dslam regarding carburation, but one thing is worth remembering, Do not attempt setting up carburation unless the motor is at normal operating temperature, which is only really achieved by running it under load, in your case on the road. Ensure that your oft removed exhaust system is not leaking at the joints!which will induce weakness. Start and run at a fast tickover until warm, then via a combination of throttle abutment and pilot air screw adjustment, obtain the best running that you can, you shouldn't require jet changes at this stage. If poss. it needs running on the road now to set needle position and slide cut-away size. main jet you can forget about for now. The generator should achieve between 14v and 14.5v across a fully charged battery, around 12.5v,if this is not the case, check the voltage at the brushes, it should be battery voltage, or very little less, at rest, ign. on. The sooty plugs could be too high a float level from over enthusiastic carb. "tickling"!I hope this may be of assistance, but appreciate that its one thing to read, quite another to put into practice, still, no info. is ever waste :D :D...Morrag

Bike fired up again. No spitting from the carbs now though, as you say Andy, carburetion higher up the revs might be buggered now. Ticks over quite nicely & has a very British sound to it.
I put the meter across the alternator brush terminals, just on the screwheads, & it's only reading 0.64 -so alternator dead?

Title: Re: Manky's XS650 Yamaha
Post by: morrag on February 23, 2017, 04:23:57 PM
With the ignition on, you should see 12+v, ie. battery voltage, at the brush terminals, whether the motor is running or not, as this is the rotor excitation voltage, and without it the Generator will not......generate!, so, check the wiring and ign. switch, as effectively, this is the difference between a PMA alternator and a separately excited alternator such as yours. Now whilst the PMA is the alternator of choice for most vehicles today, there is nothing wrong with your version, provided this battery voltage is available to start the generation of A.C. so check that again, and ensure the wiring/switch relationship is sound, ok. As for the stator windings, well they can fail in either alternator type, and that can be easily checked by resistance checks by, with respect Andy, someone who perhaps knows a little more about "Elektrickery" than your good self ;) ;)..

There will be enough power in the battery to get you to and from a local MOT. Get that done and dusted then deal with the charging. At least you can do a few local runs and determine what else needs fettling and gets it on the road.

It's one of those things, it might be easy if you know how............

This is what someone sent me when I said I didn't understand electrics......

Quote
Motorcycle electrics

Electricity isn't caused by cold fusion, that’s rubbish, and forget all that nonsense about magnetic fields and the flow of electrons along a conductor, that’s a myth put about by bike electricians to support their lavish lifestyle at your expense. The reality is ... smoke!  When you think about it, it all becomes startlingly obvious – smoke makes all electrical things function, if smoke escapes, the component stops working. For example, the last time you had to grovel under the car to replace the starter motor, didn’t it start smoking before it ceased working? - of course!

The wiring loom on your vehicle carries smoke from one device to another, pumped around the system by the alternator, and when a wire springs a leak it lets all the smoke out and everything stops. Starter motors require lots of smoke to work properly, so they have very thick wires going to them. The battery stores up lots of smoke dissolved in battery acid, which is why they were once called accumulators, until it became apparent that we unwashed home mechanics would twig to the secret. Naturally, if you try to dissolve too much smoke in your battery it will escape through those little holes in the top, which is why those batteries with sealed tops explode when they get too much smoke in them.

With regard to Joseph Lucas and his wrongfully sullied reputation, why is he so maligned? Why are Lucas components more likely to leak smoke than, say, Bosch? Because Lucas is British, and all British made things leak. British motorcycles leak oil, British sports cars leak rain, British brakes leak fluid, and British governments leak military secrets. So naturally, British electrical components leak smoke!

Hope it helps.............

There must be a tutorial which could help you woth your phobia Andy, with simple analogies for voltage (height of watefall), current (amount of water flowing down the river), and resistance (a bit more difficult but restrictions in the flow comes close).
The relationship is a simple triangle of V/I times R which can't change nomatter what.
Then you have DC (direct current), which is a battery type output, compared to AC (alternating current) which swings from plus to minus and is derived from alternators with at least some residual magnetism.
Go on google it....

Post by: hydro on February 24, 2017, 06:37:07 PM
I am not familiar with the XS charging system but it will go something like this :-

AC voltage generated by the alternator which then goes in to a rectifier which changes the
AC to DC, the DC voltage then goes in to a regulator which then goes to the battery.
(some rectifier and regulators are combined units)

1) Start at the alternator and check for AC (not DC) voltage
you should/might have 3 wires the same color coming out from the side panel
usually white or yellow, set the DVM (digital volt meter) to AC volts and check
the voltage coming out of those 3 wires, put the two probes on any of them 3
wires in any order and you should have AC voltage, I dont know how high but
at a guess maybe 20-50V.

2) Check DC voltage 20-50 is coming out of the rectifier

3) Check DC voltage is coming out of the regulator about 13-14 you should see

Do the above tests with the engine running lights off and on a high tickover.
After the above tests it will give you an idea where the fault is.

Going by that diagram what I said above was right

So start off and check the 3 white/yellow wires coming out of the alternator
for AC voltage, you should have anywhere from 20 and up on any combination
of them

make and model if you can


Title: Re: Manky's XS650 Yamaha
Post by: Sid_Vicious on February 24, 2017, 11:22:46 PM
If you are gonna test the white/yellow leads before the rectifier you have to switch to the 200 mark down in the left corner on your (Olds) meter then it's on for up to 200volts ac. Hydro there is a pic of the meter at page 123..So you can see the make of it :) On some bikes it can be between 40 and 60 volts ac so the 200 is much safer than the 20mark next to it ;D

Struggling with enthusiasm for this at the moment, but had a boost yesterday from Mr Hornet6, who's made me a rather splendid new battery box.
I made the original from mild steel, but realised afterwards that I couldn't remove the battery cos the box fitted from underneath the bike & there wasn't enough clearance above the box to lift the battery out, or clearance under the frame to drop the box out.
So I needed a removable front panel. Hornet, (Jon), got in touch & hey presto, one stainless steel box with removable front section. Lovely work Jon & super fast service. Very much appreciated. Thank you.
Although it's stainless, I'll powder-coat it black, the same as the last one.

Put the powder-coated, modified kickstart pedal together & on the bike. So this has a large, flat Harley style rubber, rather than the original Yam' round bar. Much more comfortable to use. The rubber pedal revolves on the shaft, so it stays flat under your foot as you kick.

So why am I not happy?
The top end of the engine's suddenly become quite noisy. Checked the cam chain tension & it's fine, so will check the tappets next, but haven't got any feeler gauges, so will buy a set in the next few days.
The clutch appears to be working, but is rattling -when I pull the lever in the basket rattles & sounds like a Ducati dry clutch set-up. No, not quite that bad, but you can hear it inside the casing. Not sure what that is. Yamaha fitted several different versions of the clutch & mine's now got an early type in a late type engine. Some had 6 plates & some had 7. Mine has 7, so can't understand what's rattling -yes, the hub nut was torqued up & a locking tab washer fitted.
Faffing about, trying to get the clutch lever stiffness/clutch operation ratio right. It pulls away O.K, so is getting there, but this is the stage of builds I hate -when I've spent bloomin' years building the thing, then have to fight endless faults & niggles. Really saps my enthusiasm. I'd happily hand it over to someone else now to sort the last few odds & ends & get it riding right.
You can hear the top end noise in this video:

 :D I used to run all my bikes on Castrol GTX. Couldn't find any when I was building this, so used Halfords Classic 20w50.
It was low because we drained some out by taking the side casing off. I ran it for about a minute before remembering & topping it up, but it wasn't empty, just low.
I picked up a set of feeler gauges today, so will check 'em.
Put the powder coated indicators back together this evening, so now need to find someone to check over the electrics for me.
I think the problem's always that when it's stationary, being built, it's all perfect. Then you fire it up & all the problems start to show up. Just takes the shine off it a bit for me, cos I haven't got the patience to work through them one by one.
Right, anyone know a Hampshire based auto electrician who can check over the charging system for me & tell me if it's buggered or not? (also got a couple of wiring issues on the Pop for them to sort out).

The old LED indicators had separate Earth wires. These bulb ones are single wire, so Earth through the bodies. Can I tuck the end of the Earth wire back into the braided sleeving & leave it, or does it need to be attached to the indicator mounting bolt with a ring terminal? Told you I know absolutely nothing about wiring.

Made some mild steel mounting straps for the new battery box to sit on today. They bolt up to the underside of the frame. The battery sits in a rubber "bucket" inside the box, (standard Yamaha fitting), so rather than welding the box to the straps, I might try bolting it. The rubber sleeve would then sit on 4 bolt heads, but I could put a thick rubber pad in the bottom of the box.

No real progress on this for a week or two.
The new battery box, kindly made for me by Mr Hornet -speak to him for all your boxy needs -is still at the powder-coaters. Their busy time of year & without a charging system I'm not going anywhere, so no huge rush.
Tom came round yesterday afternoon to return my welder he'd had on long term loan, (Clive very kindly donated his old one to him, so now he's got one of his own. Ain't forum Monkeys lovely people). I know absolutely nothing about wiring, but Tom's building an XS too & has taken the time to research the electrics online, where I just look at the diagrams & give up. So he double checked the alternator output & battery input.
Confirmed what I thought. Battery, 12+ volts, 11 volts with the ignition on, (the lights are wired into the switch so tail & sidelight on all the time). Engine running -no output from the alternator, (it actually reads 0.6). same reading at the connection to the regulator/rectifier.
So it appears the alternator's kaput.
There are ways of removing it & testing it. There might be a second hand one somewhere on Ebay, but my bike's 37 years old so another's probably going to be just as worn. Tom's got an American permanent magnet system on his XS & to be honest, I think I might as well do the same. At least everything will be new, (& warrantied).
While we were running the bike to check the output we lost all power. Pulled the main fuse & it looked fine. They're the old fashioned glass fuses. Swapped it for a spare & everything worked. A problem I used to get with my Triumphs years ago. The metal end caps detach from the fuse wire & break the connection, but still look intact. I've already got a replacement modern blade fuse box so that'll go in while we fit the PMA, (Tom's unwisely volunteered to help wire it in).
Had a lot of vibration around the front end/engine while revving the engine. Might just be the carbs not quite right after I lifted the needles to compensate for the exhaust baffles. Will investigate it more once it's charging properly.
Still need to sort out the rattly clutch too.
Tempted to fit the new charging set-up then put it into a local bike shop to sort everything.
This is the part I always hate. Enjoy the creative, building side of it, but absolutely hate the months of fettling, fine tuning & fixing. No fun at all. I just want to fire it up & ride the damn thing now.

Had a look at the Low Brow site, and they’re showing a Hugh's Handbuilt Yamaha XS650 Complete PMA High Output Charging Kit.

Are you going for the high output version since Tom's version, if memory serves me right, the 65W version, is out of stock?

Hope you’re ready for your HMRC “donation” when it arrives in good old Blighty !

Yup, the high output one.
The customs charges seem completely random -I've bought stuff from the States & been charged a fortune, then the next time, nothing at all. It's like they just pick a percentage of incoming goods to charge.

That could maybe be because VAT is payable on goods from the states that are valued at more than £15, which means smaller value items aren’t charged....
https://www.gov.uk/goods-sent-from-abroad/tax-and-duty

I’m pretty sure the following happened a few years ago - There was a ‘debate’ in respect to paying duty on the delivery charge (p&p) too, but it was argued that while some of the delivery charge was in respect to the goods coming out of the country of origin, some of the charge was for transportation etc in the UK, and as the proportions couldn’t be defined, VAT on the delivery was removed.

A few parts back from the powder coaters today.
The new battery box, kindly made by Mr Hornet, plus the mounting straps for it.
Also the triangular electrics box access panel. This fits under the seat.
The original plan was to flip the seat up to gain access to the box at the roadside, using Dzus fasteners so I don't need a tool to get into the box, with additional access by removing the 2 side panels with an allen key. The seat front mount/hinge doesn't lift high enough for proper access though. So I've bought a different style of mount that should work better & will mount a new blade fusebox to the underside of the access panel, on extended wires, so I can lift it off to check the fuses.

Post by: Manky Monkey on April 17, 2017, 08:23:00 PM
Didn't have the bolts to fit the battery box & can't by any till tomorrow, so I had a look at the saddle.
The original idea was to hinge the seat up to get access to the electrics box, via a removable panel held with Dzus fasteners, so I wouldn't need a spanner to check the fuses. The front seat mount I had wouldn't allow the seat to lift high enough though. I was never very happy with the look of the front mounting tab on the frame anyway, so have bought a ridiculously expensive billet stainless mount to replace it.
So today I attacked my nice shiny frame with a hacksaw & cut the old mount off.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on April 17, 2017, 08:29:06 PM
The new mount had to fit on a flat surface, rather than on a frame tube as the old one did, so is an inch further back, which will actually be more comfortable. Unfortunately that means the springs no longer line up with their posts, but I had to sort the front mount out before I could see just how far out the springs would be. I'm tempted to try just tweaking the studs on the underside of the saddle, but suspect that'll end in disaster. The posts the springs fit over don't need to be as tall as they are, so shortening them may help when locating the springs.
I'll sit & look at this for a while before taking any action, once I've got the front mount securely bolted in place, (just propped there with an old bolt for now).


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on April 17, 2017, 08:32:02 PM
The electrics box will be a lot more accessible though. I'm going to relocate the fusebox from the base of the electrics box to the underside of the removable panel, with enough wire to allow me to lift it off & flip it over to check the fuses. I'll probably fit a multi pin plug so the lid can be removed completely. I'm also changing from old glass type fuses to vibration proof modern blade ones.

Just been helping out on a bike engine kit car, getting clutch slip at high revs. New clutch fitted, new stronger springs and now no clutch. Feeling a bit " been here, read this". Took it to bits, the springs appear to be stronger and 3 mm longer. Tried again, same result. Put the new clutch with the old springs and all works fine. So the 3mm on the springs are the cause. Its an R1 engine which is Yamaha i believe. Seems odd that this problem should arise so similar to your clutch problem.

The clutch is working but needs some adjustment, but very rattly when the lever's pulled in & the plates seperate. Maybe I'm just getting over critical.

R1 clutches are a different ball game. Been helping a mate who has a crossplane R1 in a grasstrack outfit. Stack height is critical as is spring weight/strength/length. We found the sweet spot has to be within 1mm of stated stack height. Took ages to sort out. I don't think the XS is as 'needy' but may be contributory.

thanks for that snippet, I've put it together without the long stronger springs and its working OK for now with just new plates. Took it out, under power it sounds like its slipping but I'm not seeing the rev's climb much, so leave itbe for now.

It might be the second hand window trim I bought on Ebay for my truck, but more likely the PMA charging system for the bike. I'll go & collect it on Monday.

Huge thanks to Tom for giving up his Bank Holiday Monday to install the new high output PMA set-up on the bike.
I'd like to pretend I knew what was going on, but I didn't. I do know though that the old system used a spinny roundy thing attached to the crank, surrounded by a fixed ringy thing, with brushes running against the middle bit.
The new one has a fixed ringy bit with a spinny roundy thing attached to the crank that spins around the outside. That's about as much as I understood.
The old set-up came off suprisingly easily.

No need to print off the fitting instructions -Tom simply scrolled through them on his phone, following the photos attached. It all seemed pretty straight forward.
The kit included a replacement rectifier/regulator. We only had to file one mounting hole out a little for it to fit under the electrics box where the original had been.
Multi pin connectors hook it all up together.

Tom's not convinced the old set-up was wired correctly, but still wasn't putting out any charge at the alternator.
Unfortunately we couldn't fire it up to test it cos there wasn't enough charge left in the battery.
I've charged it up again & also ordered the necessary connectors to relocate the fusebox & hook up the new indicators. So hopefully one more visit from Tom should see the electrics sorted. Thanks matey. :)

A bit more progress today, after a few weeks off from this, apart from a visit to the local transport festival a couple of weeks ago.
Tom had some spare time this evening, so called in at the garage & we tested the new PMA charging system. Hurrah! It works! 12 volts at the battery, sightly more on tick over, 14+ with a few revs. That'll do. :)

Tom also began wiring the new indicators up, but didn't have the right connectors, so will come back another day to finish off. Thanks Tom. :)
So, jobs left to do:
Wire the indicators.
Extend the wiring to the new fuse box under the seat, using multi pin connectors so I can lift the access panel completely off if required.
Strip the clutch out -again -& make up one good one from the old & new parts, (nasty clutch rattle, which I'm told is the cush drive springs on the back of the basket). So original basket to go back in.
Sort the seat spring mounts out so the seat can be easily lifted to gain access to the electrics box.
I'm going to buy new threaded bungs for the fuel tank to take the new taps I bought recently. There's a run in the paint which needs sanding out, so I figure I might as well get the bungs welded in, then respray it.
Ask Mr Dslam very nicely if he'll retune the carbs for me now I've changed the exhaust baffles.
I think that's about it :)

Many thanks to Tom for calling at the garage on his way home from work tonight & wiring the indicators for me. Neat, tidy & functional -& so's his wiring :) Job done. They work just fine & show up very well. Despite using a relay meant for LEDs, the flash rate's O.K too.
I've ordered some more connectors, so we ...he, can tackle the fusebox, swapping from an old style glass fuse type box, to vibration proof modern blade fuses. I've also ordered an LED tail light bulb as it's already blown one normal one due to vibration.
Next job is to tackle the clutch -again. It makes a horrible whirring rattle when the lever's pulled in, but seems to stop when it's in gear with the clutch pulled in. You can feel vibration against the outer casing, making me wonder if it's actually touching the inside of the case when the lever's pulled in & the plates are seperated. Need to pull the cover off again & see what's going on.
It engages gear though & pulls away, so very nearly there :)
I checked the exhaust, using the decibel meter app' on my phone. At roughly 500mm from the end of the pipes & 45 degrees to them, which I think was the placement when my truck was tested, it read between 75 & 80 db at tickover & 85 when revved, which ain't bad at all.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 08, 2017, 03:14:26 PM
Hmm, new problem noticed today-
Ignition on but without the engine running, headlight wired to the ignition so the sidelight's on all the time, turn the indicators on & the headlight dims with each flash. Didn't notice yesterday whether it does it when the engine's running. Normal? Just the flashers drawing power away from the headlight, or a problem? (common Earth?).


Title: Re: Manky's XS650 Yamaha
Post by: tom_prs on June 08, 2017, 03:24:24 PM
I'd imagine its because the engine isn't running to charge the engine. Similar thing happens to the rear light; it'll get dimmer when you switch from side light to main beam as it's drawing more current from the battery.

Give it a kick and see if the side/head light is noticeably dimmer with the indicators on.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 08, 2017, 03:54:51 PM
That's what I assumed Tom, but wasn't sure. I was just dropping some parts off at the garage on my way home, so will have a better look tomorrow. Got wet & cold at work today, so having a hibernation afternoon :) My day off tomorrow.

 ;D I'm never building anything else, so I'm determined to get it right, whatever it takes. If that means another 6 months to get the clutch fixed, the fuel tank re-welded & the fusebox re-wired, then so be it -but hopefully it'll be quicker than that :)

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 08, 2017, 08:51:42 PM
Yeah, never really noticed it on bikes before, but the lights are wired to come on all the time with the ignition on & it's quite a pronounced dip in headlight brightness with each flash of the indicator. It'll be fine :)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 09, 2017, 11:21:14 AM
Checked the lights with the engine running. They get brighter when it's revved, which I guess means it's charging O.K. the sidelight bulb in the headlight dims as the indicators flash, but the low beam doesn't seem to, or at least, not noticably. The LED light in the speedo also flickers in time with the indicators. Rear light seems O.K.
Front end lights need a better Earth?
Engine started first kick, so I assume the charging circuit's good now.


Title: Re: Manky's XS650 Yamaha
Post by: flc on June 09, 2017, 02:54:27 PM
I think you should be ok as the alternator gives full charge at about 1500 rpms ,so you won't notice when riding, my mums old reliant regal had to be revved at mot time to get the indicators to flash at the correct speed. Sounds like like everything works as it should.


Title: Re: Manky's XS650 Yamaha
Post by: Archie on June 09, 2017, 04:54:34 PM
Every bike I've had is dimmer on the lights at idle than when revved up.

If it's running fine and the lights are working don't worry about it


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 09, 2017, 08:11:00 PM
Yeah, I'm sure it's fine, but I haven't had a bike for a few years & never noticed it before, but as I said, this one has the lights wired on all the time so it's more noticable.


Title: Re: Manky's XS650 Yamaha
Post by: scannerzer on June 09, 2017, 09:31:21 PM
You could try a heavier earth wire if all the front lights share an earth,if for example one earth runs 2 21w indicators and 1 5w side light then the earth would need to ba able to handle 47w plus a bit for comfort so w/v=a....47w/12v=3.91a, I'd go for a 6amp cable minimum

The mini speedo has bright blue LED illumination which I finf quite offensive -why blue? Surely white would be the logical universal colour? Really stands out on a green bike as just wrong. Can't change it cos the gauge appears to be a sealed unit.
Yellow headlight tinting film. That'll fix it. Blue + yellow = green right?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 10, 2017, 06:42:10 PM
Nope. Apparently it just equals an even brighter blue. I give up. I quite like the yellow though when it's parked up with the ignition off, (speedo's wired to be lit all the time the ignition's on), & a plastic film might save the glass from stone chips as it's right next to the front wheel.

Nope. Apparently it just equals an even brighter blue. I give up. 
Not sure how that worked !  I've never quite got my head around how adding all the colours of the light spectrum gives white light. Shining light through a coloured film is not quite the same as mixing colours. If you want it to light up green, try a green filter. Should work as blue and green are next to each other on the colour wheel.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 11, 2017, 07:32:50 AM
 :) I know -baffled me too, but I've given up questioning these things now. It shows yellow when the light's off, but seems to be almost clear when you shine light through it, which I suppose is what you want when you use it on headlights. Less than a quid on Ebay for a 6" square of adhesive film, so worth a try. I'll leave it on there now.

Threaded inserts have arrived from the States for the fuel taps. Although the taps are advertised as 3/8" NPT, that appears to actually mean they're an NPT thread to fit 3/8" fuel pipe. The thread's actually 5/8" NPT.
Sorted now, but I need to get the old fittings cut out & the new inserts TIG'd in, then respray the tank.
My fuel pipe's 1/4" I think, (6mm), so I'll either have to try & stretch it over the 3/8" spigot, (10mm), or try & change the brass spigots for smaller ones. I've got spare taps so can experiment with removing one.

More electrical gremlins. I swear I've never had a bike that's fought me every step of the way like this one.
Stopped in at the garage on my way home from work & fired the bike up, just cos I can. Ignition on -barely any lights & indicators hardly flash. Fired up first kick, but died the second I tried the lights or indicators, like flicking a kill switch.
Tom thinks it might just be a matter of the bike not being used enough to charge the battery, (it charges when revved, not at tickover), or possibly a second duff battery. He's wiring the relocated fusebox for me on Sunday, so I'll pull the battery out & charge it again before then.
I just want to be able to ride the damn thing! :(

It may be where you keep starting and letting it tick over. needs a run to recharge the battery. wont charge on tick over small amount of voltage being generated. or could have a power drain check battery volts with nothing on. no wait a moment with ignition switch off.

Big thanks again to Tom today for giving up his Sunday morning to make a start on wiring in the new blade type fusebox.
Instead of being buried in the bottom of the electrics box like the last one, this one's fitted to the underside of the access lid, with long enough wires to remove the panel & flip it over to check the fuses. Modern blade fuses will also be more vibration proof than the old glass ones, (blown several of those already). The wiring's on multi pin connector blocks so I can remove the lid completely for easier access to the rest of the electrics.
Thanks Tom. Very professional looking job :)

Many thanks to young Tom for coming back this morning & completing the tidying up of the electrics box, hooking up the new fusebox on multi pin plugs to the underside of the access lid, shortening various other wires, heat shrink sleeving a lot of it & generally making everything more accessible. Thanks Tom. I appreciate it.  ;)
Unfortunately, we now have an issue with the indicators. They haven't been touched recently, but now, when the headlight's on low beam & the indicators are switched on, the headlight flashes! How can that happen?! They obviously don't share the same feed, but may share a common Earth. Sometimes all the indicators come on, but don't flash. Is current somehow bleeding back through the circuit? They're bulb indicators, not LEDs & we've changed the relay from an LED one to a standard bulb type one.
I know a low battery level can cause odd stuff like that, so I've taken it out & charged it up again. I'll reconnect it next time I'm at the garage & see if that's magically fixed it, but if not, we'll have to experiment with seperate Earths on everything. I'm sure we'll get there eventually, but this bike really is fighting every step of the way.

A bad earth may cause this problem, take a spare temporary wire from negative on battery to each affected light to see which has the bad earth, this will identify which circuit is not earthed well enough

:) It's weird. We, (Tom), hasn't touched the indicator wiring for a while & it was working fine. I charged the battery overnight & refitted it this afternoon. The engine runs fine, but now when I switch the indicators on, opposite corners light up!
Tom's got a spare, good battery so we'll try that next.


Title: Re: Manky's XS650 Yamaha
Post by: tom_prs on July 04, 2017, 08:25:56 AM
It sounds like charging the battery has made things even more unusual? I'll pop over with a spare decent battery to see if that helps, but I'm starting to think it may have something to do with the ground connections?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on July 04, 2017, 02:52:38 PM

I've decided to change the seat again!
I'm going back to the one I started with -the one the frame was built for. It's slightly bigger & more comfortable than the one that's been on there recently. The cover got torn, so I bought a new one & passed the old one on to Archie. He's not using it though, so I'll get it re-covered. Tom's got the one  I took off & the previous one I tried went to Loony, who passed it on to Archie!
Anyway, I've moved the front mount, so now the spring mounts don't line up. Nothing's ever easy is it. I've ordered some "hairpin" springs, which might fit easier than coil springs, for a tenner from Ebay, but if not, I might just rigid mount it -yeah, I've had plenty of hardtails before & seat springs do bugger all anyway. We'll see.

I had a similar lighting problem on a car (Mk3 Cortina I think) - it was caused by one of the bulbs being on the way out, really odd, the headlights flashed instead of the indicators.  Technically it wasn't possible according to a mechanic friend but replacing a headlamp bulb sorted the problem permanently.

Post by: morrag on July 07, 2017, 09:23:07 PM
Well, that really sounds a bit unlikely, but....Regarding your probs Mr M, remember the frailties of "Earthed return" wiring! you are relying of a myriad of nuts bolts, paint, rust!! etc. etc. to form a return circuit, therefore, and if the obvious, or indeed not so obvious, solutions fail...then simplify the problem circuit by using wire "jumpers" with crocodile clips to replicate a sound return circuit, and prove the wiring, or otherwise, that way, so fully charged battery, guaranteed wire return circuit, and correct load, ie. 42watts for conventional flashers,& off you go ;) Morrag

New seat springs have arrived.
"Scissor" or "hairpin" springs, rather than the previous coil type. I've moved the front mount back by an inch, so now the spring mounts on the frame don't line up with the ones on the seat. Scissor springs will hopefully line up better.
I need to get some sort of "top hat" adaptors machined to sit into the old mounts on the frame, with a raised pin in the centre for the new spring to locate on. Anyone fancy doing a little cash in hand lathe job?
Not sure how much the new springs will compress when sat on. If they squish down too far, the back edge of the seat will foul on the mudguard. I need to get that re-upholstered though, so could always modify the back edge to clear it.

Haven't looked at this for a week -getting home from work each afternoon absolutely knackered at the moment, so haven't been up to heading back out to work in the garage.
Spent 2 hours with a hacksaw blade wrapped in a piece of rag this evening though, slowly working through one of the seat pins. Still got the other one to do, but not tonight. Then clean them up & respray everything while I look for someone to machine some stainless bungs to push into the recesses with raised pins for the new seat springs to locate on.

Took the tank over to my mate Bernie the fabricator today. He's going to drill out the old fuel tap mounts & TIG weld in the threaded inserts for the new taps, (the old ones didn't have a very high flow rate & didn't shut off properly, resulting in the carbs flooding when the bike's parked up).

A smear of filler over the lumpy seat mount welds & a coat of black. Needs flatting back & another couple of coats, but not too bad for an aerosol job -I'm the aerosol doing the job :)

That'll be Martin from Humpsohn Electrics - he's so much in demand he can pick and choose - and he doesn't like to go far cos people don't want to pay his mileage.  But he REALLY knows his stuff, bikes as well as cars.

Strange day yesterday ( yes your correct BG ) my buddy Martin originally told me the sparky ( Martin) wouldn't come to me a few years ago ? And he didn't do bikes ? So I've never used him..in desperation I rang and spoke to his wife.."no problem" she said..he turned up later than she said ,but it was pouring down..traffic..
"So what engine you using in your trike ?"   "Reliant "  I said..I opened the shed doors.."WOW!,that's nice "
I think he thought it was going to be a typical chequer plate,angle iron job ?
Turns out he does do bikes/chops/hotrods/cars..but only the ones he wants ? So after some fault finding and a MASSIVE shock from my alternator. ( price went up then  :o) he left me with some homework to do and to call him back once it's ready ? ;D..and Andy,he's worked on your same engine in the past ?

Brautifully machined stainless bungs for the modified seat mount collected from Mr Dslam in Surrey this evening. Unfortunately, due entirely to my rubbish measuring skills, they're very slightly too big -so back to his workshop tomorrow for some adjustment. Thanks Andy :)

Post by: Manky Monkey on August 01, 2017, 02:48:17 PM
2nd visit to Mr Dslam's Surrey workshop yesterday evening. Seat bungs turned down on the lathe again. They're now a perfect fit -a gentle tap with a socket & a mallet should seat them into the frame recesses nicely.


Title: Re: Manky's XS650 Yamaha

Post by: Manky Monkey on August 01, 2017, 03:00:37 PM
But, true to form with this bloody bike, another problem's cropped up -the mounting eyes on the 2 springs are different sizes. One's just over 9mm, the other's more like 8. Small enough that it won't fit. Poo.
Cheap Chinese chrome so if I try to pry it open, not that I've got anything big enough to pry sprung steel with, it'll destroy the chrome. I had a look at the Ebay ad I bought them from & they were 10 quid a pair. So I've ordered another pair. Hopefully I'll end up with at least one more larger sized one. Or a pair of smaller ones & I can beg Mr 'Slam to turn the pins down a little more -which is why I haven't tapped the bungs all the way in yet.
I hate this bike.

Title: Re: Manky's XS650 Yamaha

Yup, both holes too small. Stoopid bike :(
I should've brought both springs over, but didn't forsee that problem. The springs are cheap enough to try another pair first, in the hope that I'll get a pair that fit, but if not, yes, you'll be seeing me again soon! :)

I've got a guy locally to rewire the Pop over the Winter -not cheap but a professional, full rewire -& hopefully the bike's just a couple of bad earths. If there were someone local just to confirm that, that's all I need. So probably not worth his while travelling up here.

I visited Mr Dslam again a couple of nights ago -I really don't know why he puts up with me. 2 minutes of lathe work to turn down the seat spring mounts, followed by several hours of chatting in the shed. Thanks Andy. I'm in your debt -again :)
Still got to rub down the black aerosol paint, but the stainless bungs fit nice & snug in their recesses & now the springs fit the pins.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 13, 2017, 09:54:28 PM
Hopefully this'll look like it was always intended this way, rather than a bodge after I changed my mind about the coil springs I used before. The hairpin springs sit nicely either side of the rear mudguard.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 13, 2017, 10:00:37 PM
I've got to flatten the nose of the saddle slightly to fit the new stainless front hinge mount, but once it's re upholstered, probably incorporating a gel pad like the one Dslam showed me on one of his bikes, I should be able to get into the electrics box by just pulling out 2 R clips & flipping the seat up to get to the access panel underneath.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 13, 2017, 10:03:53 PM
I was worried the back of the seat would hit the mudguard when I sit on it, so deliberately went for 3" tall springs. Seems to be plenty of clearance, but I can't try it till I've sorted out the front mount.
An itsy bitsy step forward, but it's getting there.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 20, 2017, 09:16:52 PM
Well, with the bottom seat spring mounts now sorted, it was clear that the top mounts didn't line up with the springs. They were at quite an angle to the mounting eyes & after trying unsuccessfully to tweak the welded studs a little, I decided to cut them off & start again. I need to file the heads of this pair of stainless bolts to suit the angle of the seat, then get them welded in place.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 20, 2017, 09:22:11 PM
Welding the studs on would bugger up the upholstery, but it needs re-doing anyway, (this is the saddle I started with, which the frame was built to suit, but I managed to tear the vinyl). I'd like to replace the 10mm foam with a similar thickness of gel, so have cleaned the seat pan back to the metal. Like my truck, I think this project's actually going backwards!


Title: Re: Manky's XS650 Yamaha

Bolt heads filed to suit & seat dropped off at a local welder.

Seat finally sorted. So this is the original seat the hardtail was built to suit, but moved back an inch on a better front mount. The coil springs have been replaced with hairpin springs, sat on posh new stainless mounts.
Everything seems to line up O.K & the seat hinges up & stays upright, giving me access to the electrics box underneath. I've been tempted to just powder coat the metal seat pan & not bother with upholstery cos it's really comfy, but I want to keep this bike longterm, so will be sensible & shop for a thin gel pad, then get it covered in black vinyl.
Right. Off to the powder-coaters with it.

Sorry Clive -yeah, running a few errands today so I was only there for a short while this morning.
The side panels come off the electrics box too, although the left one would involve taking the chainguard off as well. Every time I've built a hardtail bike, the leccy boxes have ended up too small & too awkward to work in when a fuse blows in the dark, in the rain, in the middle of nowhere -so I'm trying to make this one as accessible as I can.
Thanks for that Bobbi. I need a gel pad that I can cut to shape, about 400mm by 300mm by 10mm thick.

Never had a genuine leather seat. Smooth, rather than laced or tooled. It needs to be tightly formed to the base to keep the curves I think.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 29, 2017, 09:18:09 PM
Seat pan back from the powder coaters. Now I need to het it re-upholstered. I've given up on the gel pad idea as I can't find one thin enough & they don't appear to fit complex curves very smoothly. So I'll stick with 10mm of high density foam, as originally fitted.

Freshly coated seat pan dropped off to Eric at Trimmania in Wokingham after work this afternoon. 120 quid in leather.

Yep and made a stand for it. A big old thing, made in about 1750, it's an earlier version of the ones in your pic. Pics. don't do justice to size of these things. It's 40" tall and all up weighs 88 lbs.

£120 for the seat doesn't sound too bad considering the work involved if it's going to be moulded.
Looks like they have interesting stuff at the trimmers as well.

Smooth leather. I've never had a real leather seat before so asked about caring for it -I remember chops with leather seats at bike rallies in my youth that had gone white & furry in the rain -but apparently modern leather's supplied already treated for weather proofing. So it'll just need wiping over occasionally. Nice.

Indicator Earthing problem fixed, thanks to Tom -now the head light flashes! Hooked up a temporary Earth & that sorted it -but now the tail light flashes!
No Earth wire on the tail light so it just Earths through the body. Everything's powder-coated so it's obviously not Earthing properly. So we'll, (Tom will), run a new Earth wire back to the electrics box. While it's apart I'm swapping the bright zinc mounting screws for stainless hex headed bolts cos they're a pig to reach with a screwdriver.

I refuse to get wound up about this build. It's taking forever & I'm not enjoying it at all -just one problem after another - but it's the last bike I'm going to build so I'll keep plugging away at it. Closed the garage door today & walked away from it for now.

Found out today that the old lady I rent the garage from is in Hospital after suffering a stroke. Obviously I wish her the best possible recovery, but have to admit my first thought was that I might have to find another garage soon, (she lives alone in a 3rd floor flat so may have to move).

Sometimes I feel like setting fire to it! :(
Not just a non running bike. Also my workbench, a stack of boxes full of spares, plus the pick-up bed from my truck.
I can rent another garage from the local housing association, but this one's at the end of the street I live in, so I could use the bike for commuting to work if I felt like it. Just more upheaval & expense.

Spoke to the old lady's daughter. It happened a month ago, (I pay the rent monthly & after trying her doorbell several times, put it through the door in an envelope). Her daughter found her on the floor of her flat, where she'd been all night. She's still in hospital & can only talk a little but was worried I'd be concerned -I am. She's a lovely old girl, but there's nothing I can do to help. So I'll carry on dropping the rent in until further notice.
We take our health for granted don't we. There's more important things in life than vehicles.

Privately owned, 30 quid a month.
I rent one from a local housing association for 43 quid a month, where I keep my truck & most of the tools & parts for it. 20 minutes walk from home. The bike one's 2 minutes walk away. Someone moved out of the block where the truck is, but I'm not sure I want 2 together -it'd be convenient but they're in the middle of a council estate & they get broken into from time to time. Mine's been O.K so far, (touch wood), but maybe I shouldn't put all my eggs in one basket so to speak. Also might look bad if I bale out as soon as the landlady gets ill. Just playing it by ear at the moment.

Thanks to Tom for calling in on his way home from work this evening to sort out new earth wires for the headlight & tail light.
The headlight earthed to it's own shell, but the headstock bearings are packed in grease, so would've isolated the front end from the frame. Now it earths back to the top engine mount.
The tail light also earthed to the shell, but the light & the frame are both powder coated, so a poor earth. Seperate wire now fed up inside the frame leg to the battery box. Sorted.
Thanks Tom :)

Got to fill , rub down & repaint various frame sections around the new seat mounts.
Got to pull the engine side casings off & investigate the noisy clutch.
Try & remove the exhaust baffles that are stuck & wrap them in wadding before Dslam gives the carbs a final tweak.

Repainted the rear light a few days ago after repairing a couple of scratches in it.
Checked it today. Yup, fine. Nice glossy black. One tiny spatter of spray paint though. It'll hardly show, but I'll just flat it back & blow another quick coat of aerosol paint over it.
Too cold in the garage. The paint bloomed, (went white & milky). Bugger.
Shake the can vigorously for 5 minutes to warm it up & try again.
Bloomed again and got a big run in it.
*Sigh* Stop now & walk away.
As I'm locking the door the sun comes out & starts to warm the garage, but I can't do anything till tomorrow when the paint's hardened enough to rub the run out.
I hate this bike, I really do.

One worthwhile observation I would make, and it applies to most projects. It is all too easy to fall into the temptation of "finishing" bits as you go, regarding paint, plating, or powder coating, etc.then , when mods. occur, and they always do! re-finishing, and all the aggravation that entails, is a certainty. Far better to build it, run it, even MoT it, and when fully sorted, take it apart and coat/paint it! one time only, obviously, the out of sight areas on 4 wheeled vehicles are fine to protect "en route", but for the rest, and I am only too aware of the temptation to giving in to "save returning to the scene of the crime!" syndrome, but it's the better way, honest....Morrag

Slightly warmer day today, so I re-sprayed the rear light. Big run in it. Bugger. Drown the thing in paint & hope it flows out. Yeah, stupid, but seemed to work. Kept an eye on it for a while & it didn't seem to "bloom", but will be about a week before it's hardened off enough to rub over with cutting compound.


Title: Re: Manky's XS650 Yamaha

I keep looking at the engine cases. The engraver must've rubbed something into the background to make the raised areas stand out more -when he posts photos on FaceBook they always look really jet black. Mine seem to have faded though. Still look good, but I'd like a bit more contrast between the background & raised areas.
He wouldn't tell me what he used, but as he's an ex tattoo artist, I guessed at tattoo ink. So I tried printer ink, bought cheap on eBay & rubbed in with a cloth. Slightly darker, but not really  enough. Made a good job of staining my fingers black though. Don't really want to use anything as permanent as paint in case I mess it up. Any suggestions?

I've been waiting a couple of months for someone to TIG weld new fuel tap mounts into the tank for me, (one of the taps leaked & I can't find the same ones again, so am changing to a more readily available design).
The outlet's too big though. 10mm when I need 6. Anyone able to machine a pair of new brass spigots for me -for cash obviously. No idea how they're fitted -either pressed or screwed in.

Pretty sure that the size will be 5/16" (could be wrong). Amal do 5/16" sized banjo fittings for the carbs.

Title: Re: Manky's XS650 Yamaha
Post by: the coppersmith on October 14, 2017, 10:21:13 AM
5/16 equates to 7.9 or 8 mm, most decent rated fuel pipe at 8 mm. for unleaded should stretch out to a 10 mm barb I'd have thought. The old hot water trick?


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 14, 2017, 11:00:41 AM
Definitely 3/8" & single banjos on the carbs, but I guess it wouldn't hurt to fit doubles, with a balance pipe between the carbs. I guess 5/16" hose would stretch to fit when warmed up.


Title: Re: Manky's XS650 Yamaha
Post by: Dslam on October 14, 2017, 08:54:24 PM
If you are going to run a single tap, run the larger pipe to a T piece with smaller outlets to suit the carbs and get single banjo's for the carbs.
Just a thought.


Title: Re: Manky's XS650 Yamaha

Post by: Olds on October 18, 2017, 06:13:02 AM
That would be far too easy. Someone likes making life difficult for himself. ;)
Taps are mounted horizontally to the tail of the tank (means that a reserve wont work without modification to the tap reserve feed pipe ) so really need the outlet 90' from inlet.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 18, 2017, 10:41:18 AM
 :P
I looked at those Terry, but the taps mount horizontally to the back of the tank, so I need right angled fittings to drop the fuel line down to the carb, (no room for a big loop of hose in front of the seat & I think it'd look naff anyway).
The taps I bought have right angled outlets so will be much tidier. They're also a bigger bore size. I don't think the previous ones were bike taps & seemed to have a very low flow rate. No reserve position.
It'll get sorted eventually.
Not much progress to show at the moment. I've cut back the paint on the rear light & re-fitted it & Tom took the bulb holder home & soldered longer wires on it. The light was hard wired -no connectors, so we had to cut the wires to remove the shell so I could repaint it, (it had a big scratch in the powder-coat & over-spray from touching in the frame). Also fitting an LED bulb while it's apart cos it's already blown one normal one, just through vibration while ticking over.
Just fed up with working on the poxy thing now.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 19, 2017, 07:58:58 PM
One step forward ...
Another visit from Tom this evening to hook up the rear light. Yup, with it's new Earth it works fine.
Better just check the other lights -right indicator, yup. Left indicator ...nope.
They were fine last week. We haven't touched anything since. Now only one side works. We took the switch apart & there's no obvious problem.
The battery's very low cos we've been using it but the engine hasn't been run to charge it up, but surely that'd affect all the flashers, not just one side? Unless one circuit has more resistance than the other?
No idea.
Battery out -again -& brought home to re-charge. Hopefully that'll fix it. If not, setting fire to the damn thing's becoming an increasingly tempting answer. 


Title: Re: Manky's XS650 Yamaha
Post by: morrag on October 19, 2017, 10:54:38 PM

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 20, 2017, 09:15:05 AM
Yeah, that's the final solution -throw them away. The bike's a 1980 model & indicators didn't become compulsory till '86, but I'm going to put it through the MSVA test at some point, so it'll need them then.

You properly need to fit a diode or resister in the circuit. 


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on October 20, 2017, 08:27:01 PM
Thankfully, a decent charge in the battery seems to have fixed it. Normal bulbs, though one bulb holder needs pinching up a bit -loose bulb. Didn't work until I tapped the indicator body.
So now we have fully working, properly earthed lights. Nathan, who wired the bike, had assumed everything would earth O.K to the powder coated frame & that the front end would earth back to the frame, but obviously hadn't realised the headstock bearings are packed in grease, which insulates the front end from everything else, (he's a car guy & hadn't worked on a bike before). Seperate earth wires have sorted it.

So I called in to see my brother in Wiltshire & hopefully it'll be done next week. He also has a mate who's a paint sprayer who should be able to repaint the tank.
So no progress to show, but the promise of progress soon.

And I've just roughly calculated in that time he's spent over £60,000 ..YES you've read it correctly ..on FAGs ?? And recently we dropped off the bike to a buddy for some electrical work,3 months later he rang to say he can't do it ? So guess where it is now (again ) ?

On a more practical level though, that means her family will want to sell her flat so I'll have to find another garage.

Thank you. I'm considering setting fire to the bike, then I won't have to bother renting another garage. So fed up with it now. It's my day off tomorrow so I'll go & see the local housing association about renting another. They've usually got loads so it's just a matter of finding one in a decent area, then cleaning it out & white washing the walls before I move stuff in. So won't be for a week or two, but I need to have something sorted before I'm asked to vacate the present one.
Spoke to my brother about the fuel tank. He's not happy about welding new threaded inserts in for the fuel taps because the only way to ensure the taps point the right way up is to use a locknut, which would leave only a couple of threads to screw it into. He thinks I ought to stick with the original smaller taps, but one of them doesn't shut off properly, leading to a leaking, flooded carb, & I can't find anything similar. I'm at the point where I might just refit them anyway & put up with the leak. :(

Why don't you dismantle them & see if they can be cleaned or repaired?
Umm -because it hadn't even occurred to me.
5 minutes later they were stripped, cleaned & working fine. Bugger & hurrah at the same time. So one less job to do ;)

We went to Big Daddy Dons on the way up to gainesville and saw the offending snapping exploding sling shot. Was quite interesting to see the evolution of all the swamp rats and switching the engine from front to back

Delivered the fuel tank to one of my brother's mates for a quick respray after work today. He remembered me from my underage drinking days when I used to tag along with my older brother & his mates to the pub. Scarily, that was 40 years ago.

Nipped over to Berkshire after work this evening & collected the fuel tank from the painter. Mr Loon painted it but it's been on & off the bike a few times & had a couple of chips in it, plus a run that may or may not have sanded out. Flatted back & 4 coats of 2 pack later it's good as new again.
So that'll be my first job on Christmas Day -refitting it, adding some fuel & seeing if it'll start after standing in a cold garage for a while.
Then I'll spend the rest of the day in my other lock-up, working on my truck. A perfect Christmas Day :)

(on the continued highjacked theme........)

What’s less well known is that Don Garlits wasn’t the only person to suffer injury from the incident.
A teenage spectator by the name of Tim Ditt, suffered a horrific injury as his left arm was almost severed by a piece of the drum from the exploding transmission.

Very interesting reading on the incident

Ooo look at that, you can actually see it flying towards him!
Accidents at drag races still happen - heavy metal objects spinning at 90 deg to the direction of travel...
I was marshalling at an autograss national final many years ago, class 5 (minis mostly in those days), left the start line. I saw something flying up from the front of one of them, then heard the bang, then saw the clutch backplate land a few meters in front of me. He was one lucky bloke, not long after the governing body made it mandatory to fit a steel safety shield between the driver and clutch housing. Not much help for the poor start line marshals where the inline engined lot take off though?

We'll I'm certainly having a white Christmas -spent all afternoon & evening whitewashing the walls of my new lock-up & now I'm overcome with emulsion -or masonry paint anyway.
I rent a garage from the local housing association for my truck & have been privately renting another for my bike from an old lady who lived at the end of my road. Unfortunately she died a couple of months ago, so I've been waiting for her family to ask me to move out, (I'm assuming they'll want to sell her flat). No word yet though, but I thought I ought to have another ready when they do.
So I've rented a second one in the same yard as the truck one. It's at the rougher end of the block, behind a charity shop, but hopefully will be O.K. I'm waiting for the association to fit new locks before I move anything in.
My rechargable lamp ran out of charge just as I put the last brushful of paint on & there was just enough in the tub to do it all. I've got another tub & brush though,so will give it a second coat while it's empty, but not this weekend.
So for the time being I've got 3 garages!

I was wondering if the previous tennant had been a particularly well organised drug addict, cos there were labels chalked on the walls -medicines, tablets, child proof bottles etc -but apparently a chemists shop next door had been using it as a store room.

Post by: Manky Monkey on December 24, 2017, 11:45:01 PM
Yeah. My phone decided to hide all my voicemails a couple of weeks ago -including several from the housing association asking me to ring them before the end of the day as someone else was interested in renting it. So I rang them to apologise, expecting it to be taken, but they said I was a good tennant & already renting one, so they'd hung onto it for a bit longer, which was good of them. I'm definitely a good tenant -they get their garages back in better condition than when I take them on! :)

Maybe. It's much higher than the other one, (pitched roof instead of flat), & made of composite material -or asbestos! instead of tin like the other one.

Christmas day today!
So I spent it in the garage, messin' with my motorcycle, (still using the old lady's garage until the new locks are fitted to the new one).
Not much progress but I got the repainted tank back on, hooked up & filled with fuel. After messing about with new fuel taps for months, my brother eventually stripped, cleaned & rebuilt the old ones in about 5 minutes. Good as new. Fired her up & after 3 or 4 kicks it ticked over quite nicely. Still problems with erratic indicators though, which I'm hoping are just down to a flat battery after the bike's been sat in a cold garage for several months. So I pulled it out yet again & will charge it in the next few days.
Then I spent some time digging out the cracked paint around the seat mounts, adding a skim of filler & rubbing it down. Squirted some high build primer over it & will leave it a couple of days to harden before flatting it back.
So not major progress, but a pleasant enough way to spend a Christmas afternoon.

Thanks -the colour matches my truck. Yeah, it'll get run regularly, just to make sure all's well.
Jobs left to do-
Finish repairing the paintwork under the saddle.

Sort the electrics out once & for all, (hoping the iffy indicators are just a flat battery).

Tidy the wiring around the headstock & try & get it all into one sleeve, instead of several different lots.

Remove the baffles, weld a small rod across the end of each so I've got something to pull them out with in future, then wrap them in wadding to try & soften the exhaust note a little.

Finally look at the noisy clutch. It's been suggested it might just need riding a bit to settle it, but I bet it's not that simple. If all else fails, I'll hand it to a local bike shop to sort out.
So yeah, should be sorted by the Spring. :)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 05, 2018, 10:22:25 AM
Charged the battery up -hmm, it feels warm. Doesn't usually do that.
Put it back in the bike. Just the faintest glimmer of light from the headlight. No other signs of life. Bugger. Looks like the battery's well & truly cooked. It was only 6 months old, had plenty of acid in it & was only charged for a few hours, the same as usual.
This thing really is fighting me every step of the way. Still looking forward to riding it, but could quite happily get shot of it at the moment. Just endless hassle.
I'm sorting out the paintwork under the saddle, but need a little bit of warmth to spray the aerosol paint -& the heater's just packed up. :(

O.K, I think I'm done with this now.
New heater's working so spent some time flatting back the paintwork under the seat this evening.
I can smell petrol ...
Oh great -the tank's leaking around one of the fuel tap mounts. There's fuel bubbling out & it's destroyed the paintjob I had done 2 weeks ago.
Seriously, I'm sick of this thing now. I've done the closing the door & walking away from it thing -I've hardly touched it for a month. I've spent years pouring money & time & effort into it, but I hate it. I deeply resent every moment I spend on it.
I've been wondering lately just how much I'll actually use it. I haven't ridden for over 8 years & I'm not sure I want to with all the homicidal idiots that are on the roads now. The truck's soaking up just as much of my life & money, but at least it's safer & I can share it with a passenger, unlike the bike.
It's not a rash, spur of the moment decision that I'll regret -I just want to cut my losses & rid myself of it. I've had enough. It's cost me 3 times what I could ever sell it for & I'm sure a new owner will fix it up in a few days for about £2.50 & have a perfect bike, but I haven't bothered draining the tank yet cos I'm hoping it'll catch fire.
2 - 2 1/2 grand. No stupid offers. Someone please come & take it away. :(

Look, take a deep breath, go back there when you can and drain and remove the tank. Give it to someone to fix, and sparay it with a rattle can. Then take the whole bike to someone who can get it working electically.
All this is easy, you can do it.
Then decide if its msva, (don't recall now if it needs one?), and if you want to do it or sell it. Don't do anything rash now, winter is a depressing time of year, things will get better, especially once you're riding it with the sun shining.

Don’t you bl****y dare sell it!

You’ll kick yourself later, esp when it’s a warm day (remember them?!!!), and imagine seeing someone else riding/showing it!!! As Del Boy would say – You know it makes sense.

Sounds like it’s time to wrap the bike in (metaphorical) cotton wool somewhere nice n safe and take some big deeeeeep breaths as Merv said................. then come back to it later.

Maybe one of those big self storage places (guessing you could choose one that won’t be damp/cold like the lock up)?

Keep working on the pop as that’s where your mojo is (at the mo, Joe/Andy).

I know its mucked the paint up, but it could be something as simple as the taps not being put in right. Maybe a little leakage from the threads.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 07, 2018, 09:34:38 AM
The taps are a tapered thread, screwing into threaded inserts welded into the back of the tank. I suspect the welds are very thin & tweaking the tap around to the right position has cracked one.
I've tried liquid tank sealants several times over the years & they've always been a disaster, so it'd mean TIG welding the existing mounts, cutting them out & replacing them with the bigger ones I bought, or just buying a new tank.
I appreciate the sentiments chaps, but I really do hate this thing. I've owned it for 8 or 10 years & It's been nothing but hassle & expense. I don't swear very often, but I've cursed this one more times than any other vehicle I've ever owned.
A forum member's offered me the full asking price & I really can't think of a good reason not to take it. I do think that once it's gone, that'll be my biking days over though -can't see me building another.

Hmm, lots of pluses and minuses here.  On the plus side,if you sell it frees you from further pain, on the minus side how will you feel in a year or twos time when it appears at a show?
For the buyer it will never mean as much as it will to you - yes a nice bike to own, ride and show, but it will have been swapped for a few quid.
At the end of the day though its your decision, good luck to you and the prospective buyer, hope it works out.

A good buddy did some wiring on it and got it running..then sat in the she'd for another 2/3 years..I restarted on it 2017..kept blowing fuses..my brother said he didn't want to spend £45 an hour for local sparky to sort it ,so hired a van and took it back to London to my buddy..but it sat there 3 months untouched due to his bad health.plus he said it needed re wiring ?? It's the wiring he did ??so back to my shed ..my brother asked a good buddy of his to look at it ..that was October ..I said get local guy to do it? Too expensive ?

Yup, I've done similar a few times.
I've had a genuine cash offer from someone here & don't want to mess them about, but I'm still waivering a bit. What I really need is someone to just take it away & fix it & finish it & deal with the inevitable teething problems -I've never let other people ride my bikes before but I'm happy for someone to take on the road testing mileage on this one. I just can't be arsed with it any more. Happy to pay for whatever needs doing, but can't face another 6 months of ferrying parts back & forth & sitting in a lock-up wrestling with it. Stoopid bike! :(


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 07, 2018, 05:28:21 PM
So ...plan B
Having had several forummers threatening to lynch me if I sell it or set fire to it, or both, it gets another chance.
I'm very, very grateful for the offer to buy it & at some point, I may still take it up, but now there's another option.
Tom is local to me, a forum member, (Tom prs), & has already worked on the wiring on mine. He's building an XS too, but his has stalled while he waits for parts & he's determined I'm not going to sell mine.
So tomorrow he's collecting the garage keys & we'll go through what needs doing. I'll repay him with lots of riding time on it when it's done. After a few years away from bikes & a noticeable increase in the number of idiots on the roads, I may have lost my nerve. Who knows. No idea how much I'll actually use it, but there'll be plenty of Tom time if he wants it.
Take the keys, send me the bills, ring me when you get home from the MOT station :)
I've got some very, very good friends. Thank you :)

Whilst not wishing to teach you to suck eggs, so as to speak, Mr. M, you realise that the tapered pipe fitting of the fuel tap, has to be sealed with PTFE thread seal, or even Plumbers pipe thread sealant, to effect a good seal, within the tank threaded insert, which is why more normally parallel threads are used on taps,then utilizing fibre washers to make the seal, tap boss to tank boss so....check out the sealing qualities on those tapered threads buddy >:(....Morrag

Didn't notice the bubbling paint for a couple of days, but looked like it was above the tap, not leaking out of the threads & when I pushed the paint bubble it oozed fuel, which would suggest an actual tank leak, rather than just fumes getting under the edge of the paint around the tap mount.

 ;D Tom is da man.
I've tried Por 15 several times, (we tried it on Flap's orange trike too), plus several other makes over the years. Followed all the instructions, went through all the cleaning & prepping stages, but it always end up peeling off the inside of the tank like a sheet of rubber, then breaking up & clogging the fuel lines.
Consulting with Tom, (giving him a "to do" list), & handing over the garage keys this evening.

my four penneth, I use 'tappox' Its real/original use is for protecting oil rigs from the sea and petroleum products found/spilt on same. Used in oil and fuel tanks with no issues. I have got 7 bikes with it in now and it seems to be stable. I used the frosts por15 once and wasn't happy with the result. Found it too thin and took and age to cure. I did all the cleaning and alkali washes etc but it still peeled out of the seam and caused more grief so you are not on your own with tank problems Andy.
Good luck with it mate as it would be a crime to let it go when you are so close. Don't let it get to you its just a piece of metal. It will be done when its done.  ;)

Very true.
I apologise again to the forum member who was all set to come & buy it, but I appreciate the messages from others who volunteered everything from storage space to a lynching if I sold it! Apparently, having followed the tribulations of the build this far, selling it would be like reading a book & getting to the end to find someone had torn out the last page!
Tom arrived this evening & we removed & drained the tank so he could take it away for repair. I believe it's going to Old Bones Customs, near Andover -but that ain't any o' my business now. :) If it proves too costly to TIG weld it up, it might actually be cheaper to just buy another tank, (about 130 quid), & fit a standard tap, although that might foul the cylinder head. Again -out of my hands ...thankfully :)
Thank you Thomas :)

It's complicated!
She has grown up kids, one of whom's been in & out of hospital most of his life. So she leads a hectic life, constantly running back & forth to hospitals & doesn't really have time or room in it for a relationship. We get on very well & care about each other a lot, but I don't think it's ever going to be a cosy little domestic life together.
We spent a few hours together yesterday & it was lovely, but I was just driving her from home in Brighton, up to a specialist hospital in Oxford. Not really very romantic :)

Bought myself an early birthday pressie.
I've been thinking about getting a bike lift for a while, but obviously didn't bother when I thought I was selling the bike. Mr Dslam has one in his Shed of Wondrous Things & it certainly makes working on bikes so much easier. I've got a knee injury at the moment, but I'm not getting any younger & scrabbling about on the floor's getting less & less appealing.

It weighed a ton! (About 200lbs actually). Fortunately the delivery driver was happy to take it to my lock-up garage, rather than dropping it at the house, but I don't think he was too impressed at having to reverse his lorry back out.

The ramp's too steep for the low slung chop, but fortunately I've got a length of bike trailer channel, kindly donated by Tony Oily Bike, so I can get a shallower run up onto the bench.
The front wheel's held in an adjustable clamp & the bike's on it's sidestand. No facility for tie-down straps, but it seems fairly secure. Yes, there's a safety bar so it can't collapse.

Yeah, I looked at those. If the lift gets used a lot I'll invest in one. The bench has a removable panel at the back to help with removing the rear wheel. Could've done with it being 2" longer cos the rear wheel's sat on the tail ramp, stopping me from removing it -a scissor jack would let me lift the back end enough to take the ramp off -before I walk into it :)
Made in China but looks sturdy enough. 300 quid on Ebay with free delivery.

Idea - You could always cut away a small section of the leading edge of the ramp, that way the tyre wouldn’t sit it, which should allow the ramp to be removed fairly easily I would have thought...........??

Alternatively have a piece of plywood or similar that the rear wheel roles onto, that way its high enough to let the ramp pivot off.

2nd alternative – how about modding the front wheel end-stop to allow the bike to move the extra ½” or so so the rear wheel clears the ramp?

As for tie down points, drill some holes and fit nice big eyebolts – they work a treat.


Title: Re: Manky's XS650 Yamaha
Post by: Tony oily bike on January 19, 2018, 10:47:58 AM

I miss having a centre stand on bikes. Not for starting a bike on as that was a near sure way of having a bike fall on you, but for maintenance and the like. You can't even check the oil level on some bikes without someone else holding it vertical.
After trying one of these at my mate's place, decided to invest in one - great for maintenance jobs, incl lifting the rear wheel, but you do need a minimum amount of ground clearance to get the thing in place.
Saying that, if a mate helps lift the bike to start with, or one end of the bike is raised, say by wheeling onto some wood, it can be slid into position.
It can also take some of the weight off the tyres if a bike is left to stand for a long time.

After reading Archies post on the 18th - looks like its Deja Vu all over again  ;D  ::)   (page 102 of this thread)

Manky Sir, you said "If the lift gets used a lot I'll invest in one." - once you played with the bike on your new lift a few times, reckon you'll have wished you'd have got the lift years ago!!!!!!  ;D


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on January 19, 2018, 11:11:57 AM
I think you're right Tony :)
I was thinking about cutting the front edge as you suggested, but because the bike's so low, the ramp's too steep anyway, so I need to use the U channel you gave me to run it up at a shallower angle. That means I don't actually need the ramp supplied with the lift at all.
I've got to go out this afternoon, but will see if I can lift the back end enough to pull the ramp out -or just do the job properly & take the bike off & start again :)
Anyone know who sells tie-down ratchet straps with loops to fit over the handlebars?


Title: Re: Manky's XS650 Yamaha
Post by: Tony oily bike on January 19, 2018, 11:58:39 AM
Flea bay can offer a huge range. Motorcross shops sometimes sell these, autojumbles and trailer shops such as (Trailer Tek in Micheldever) are another option.

There’s a choice of straps etc.
Fabric loops (also known as tie-down extensions) can go round any painted / chromed metal surface with the strap hooks then attaching to the loop.
 The plastic-coated metal hooks (as found on most tie downs) can go directly on the bikes surface. Ensure clean so as to prevent any scratching or fit clean rag underneath..
Alternatively run the strap from the tie down eye, to the bike, around the point of anchorage (maybe with a soft rag under the strap) and back to the eye.

Ratchet straps allow for a controlled and ‘heavy’ amount of pull, hook / end options are available but will require searching

Re your front wheel clamp – Some folk use the roll-on type of wheel chock (suitably anchored to the lift) whereby the bike is pushed into the chock, and the chock simply holds the bike vertically. From here it can be tied down if/as required.
Others have a different type of wheel clamp that is manually tightened against the wheel, which then hold the bike vertical.From here it can be tied down if/as required.

Post by: Manky Monkey on January 19, 2018, 01:09:13 PM
Ahh, hadn't thought of looping the ratchet straps around the bars -I've got some short ones somewhere.
My ramp's got an adjustable clamp, but the instructions say to use it in conjunction with the bike's sidestand, (the clamp's offset to one side of the bench for that reason). There are holes in the bench to move the clamp forward or back, so I can use those for eye bolts.
Tail ramp removed.

I would also make a pair of "sideways extension legs" - (patent pending), bolted to the bottom bars to stop the whole lot from tipping onto your lap.

Tail ramp removed.

I'd suggest eye-bolts at width extremities of the table for maximum (triangulation) effect.

If no chock is used, both front & rear eye-bolts roughly in line with where the tie-downs are attached to the bike, so the tie-downs don’t try and pull the bike forwards or backwards, or possibly try and rotate the steering.

Using a bolted-down chock like the blue one (which supports the bike, free standing & vertical), the front eye-bolts should be positioned such that the straps pull the bike deeper into the chock. In my humble opinion, this makes for a nicely stable work place with the benefit of known where the centre-of-gravity is.

When we’ve trailered bikes, looping the tie-down strap around the fork leg immediately above the lower yoke, has always been preferred practice (solid position & doesn’t put any load on the handlebars clamps, and doesn’t tempt the bars to rotate within the handlebar clamps)

Consider also locking on the front brake – a piece of old inner tube around the brake lever and throttle grip is a cheap method.

Popped into the garage this morning to alter the clock -found for some reason it was reading quarter past 4 at 11.0. clock in the morning.
Tom's been busy. Ably assisted by Archie, they've refitted the fuel taps, using liquid PTFE sealant on the threads, tidied up the partly done paintwork under the saddle, fitted the triangular access panel to the top of the electrics box, with the fusebox attached to the inside of it, then fitted the freshly leather upholstered saddle.
Nice job boys :) It's finally starting to come together now.

Big news!
Having left Tom to his own devices with the bike for the last few months, he texted me this afternoon to say he rode it to the MOT station today -& it passed!
Woo hoo! I'm so excited! Really didn't think the day would ever come. I've never had so much hassle with a bike build before & came so close to selling it, (sorry Steve), but Tom stepped in to take over the final few tasks & has done a great job.
Still got a noisy clutch but he's taking a look at that tomorrow & it'll hopefully be sorted. He reports it rides well, no scary handling quirks or worrying noises. The only advisory was a loud exhaust. We've recently tried to muffle that a bit by wrapping the exhaust baffles in wadding, but that seems to have just made it run extra rich, so Tom's removed it again.
I'll collect the MOT certificate from him tomorrow so I can tax it, then it can finally hit the streets.
I've promised Tom he can ride it whenever he likes & I really hope he does.
Thank you my friend :)

 ;D Had a manically busy day at work today, but managed to swing by Tom's parents' house, a few streets from my Postal delivery, in the van & grab the MOT certificate from him. He & Archie were on the driveway, tinkering with bikes. Nice to see you chaps & sorry I couldn't stop :)
So I just had time to collect the logbook from home & walk into town before the main Post Office shut at 4pm. We now have tax!
And it's immediately started raining. Proper, Biblically proportioned floods.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 12, 2018, 07:45:16 PM
So.
Noisy clutch.
It's had a whirring vibration going on when the engine's running & the lever's pulled in. Sounded like the clutch plates were seperating & somehow rubbing the inside of the engine casing.
Mr BayChimp & I stripped the clutch assembly & rebuilt it several times with no success, so Tom drained the oil & pulled off the casing today.
Yes, it has been rubbing, but the problem seems to have been the casing, not the clutch.
It has a recess on the inside, where the Yamaha logo was stamped on the outside. My brother TIG welded the letters up before it was engraved. In the middle of the rectangular recess was a pip. A domed profusion about 10mm tall. Nothing to do with the welding -it looks like a casting thing. It doesn't serve any purpose, but happens to line up perfectly with the centre of the clutch & has been rubbing. No sign of aluminium dust in the oil, so hopefully no lasting damage.
Tom used a Dremel to shave it down & reports it still rubs ever so slightly but is much better & will probably bed in with use. The clutch itself works fine as far as I know.
I vaguely remember buying spare cases at a local autojumble a few years ago. Some models have a dipstick & some have a sight glass in the casing. I wanted the plain, dipstick version, so may have swapped them -I genuinely can't remember -but the clutches all work the same & shouldn't be able to touch the case. Odd, but the problem seems to be fixed now, which is all I care about :)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 13, 2018, 08:38:10 AM
After talking to Mr Dslam this morning, maybe I didn't explain that well. The clutch face has contacted the inside of the casing, but just left a black mark where the 2 have touched, not ground away the pip. We were expecting to find a huge swirl mark. It only touched when the clutch was pulled in with engine running, which really hasn't been very often -a couple of times in the garage & when Tom rode the mile or so to the MOT test & back again. He's checked the inside of the cases & the filter & changed the oil. So I'm pretty confident there's no damage or particles floating about in there. I haven't seen it in person yet, but he tells me he can just hear it contacting with the lever pulled right in. Yes, I may well pull the cover off again if it doesn't quieten down in the first few miles, but it sounds like it's pretty much sorted.

Tom reports the bike is now safely back in my lock-up garage. I've been out all day though, so still haven't seen it since it's been road legal. I haven't ridden since I sold my last Speed Triple to Loony in 2010, so will be a bit wobbly for a while! I hope to get out one afternoon this week for some practice.

I was sat in my Post Office van this morning, waiting for my partner, when a bike rode past. I heard it coming & assumed it was a Harley, but a pale green hardtail chop went past.
That looks nice. It looks just like mine ...just a minute!
Tom had some time off work so was out for a spin & had deliberately taken a detour around my Postal route on the off-chance I'd be about.
Looking good Tom :)

 ;D To be perfectly honest, after a few months away from working on it, I'm more focused on trying to get my truck finished now, so I can finally free myself from endless garaging. It'll be great to have the choice of 2 custom vehicles!
I'm hoping Tom gets all the bugs ironed out before I get to ride it :)
Today's report:
Once it's hot, it's a bugger to start. Not sure where to go with that one. Kickstart only & mk 1 Amal carbs with no choke. Presumably there's a knack to it that he hasn't found yet -or you just have to wait for it to cool down?
He says the comfort limit of the hardtail's about half an hour -which rules out riding it to Scotland for my holidays -unless I do it in lots of short hops. That may be just a personal thing though. I've got a well padded bum & have ridden hardtails 100s of miles at a time -but I was a lot younger then.
There's an occasional clattering noise somewhere on the left side when riding, which I'm guessing is the chain whipping against the chain guard. No, I'm not taking the guard off! We can try adjusting & lubing it, but may have to look at fitting a chain tensioner somewhere. One of the American custom companies does one with a spring loaded sprocket, rather than a rubber wheel or blade.
I hate teething problems.
This is the point where I usually give up & flog the damn thing, but I'm determined not to this time cos I'll never build another bike. My cunning plan is to give it to someone else to ride & sort out for me! :)

Post by: Manky Monkey on May 15, 2018, 10:38:54 PM
A nice comfy chintz cushion, that's what it needs :)
Tom's not used to the lack of suspension & I haven't ridden at all since 2010, so we'll probably just adjust to the bumpy ride.
He mentioned earlier that he "tickled" the carbs while trying to start it when it was hot. It's nearly 40 years since I used to ride Bonnevilles, but I think I only had to tickle them from cold. So may just be a matter of finding what it likes.
The bike's back in my garage at the moment, so I had a quick check of the chain earlier. Definitely needs adjusting. It was slack enough for me to slap it against the underside of the chain guard by hand. It may have just settled or stretched a bit with first use. So hopefully some adjustment will cure the rattle Tom & Archie heard. No suspension travel to worry about, so it can be run slightly tighter than a normal bike.

First time my 2 projects have been together for a few years :)

I still haven't ridden "the Frog" myself yet, but I'm really pleased Tom's getting some enjoyment from it -that's the whole point of building these things after all. :)
Today's list of minor niggles:
The speedo's stopped working, which appears to be a cable problem. Either the cable itself has too tight a bend in it, or the 90° angled fitting on the end is slipping. It's a car fitting with a plastic stub that connects to the original drive unit. I think the plastic bit needs replacing with a short length of normal metal bike speedo inner cable.
There's still an unidentified rattle from the left side, possibly the exhaust heat shield.
The cylinder head gasket's leaking between the fins on the left side. May be worth just retorquing the head bolts or trying an oil additive to seal the leak. If the head needs to come off, it's an engine out job -a big job.

On the plus side, nothing's vibrated loose or fallen off, all the lights still work & the clutch seems to have quitened down. The clutch lever operation is now much smoother too.
No idea what it's doing to the gallon, but the boys did manage to run out of fuel this evening. Fortunately they had the ingenuity to use a bottle they found at the roadside to transfer fuel from Archie's 1100 to the XS.

It's the first time I've seen it moving under it's own steam & I must admit I'm pleased with it. Might seem strange that I haven't leapt in it myself yet, but with that project now complete & being road tested, I just want to crack on & get the truck done too. I know the bike's in safe, sensible hands & I'm more than happy for Tom to keep on pootling & refining it for now. Good to see you guys :)

Post by: Manky Monkey on May 20, 2018, 10:18:25 PM
Well, Sunday dawned warm & sunny, so I dug out my riding gear & finally took the Frog out to stretch it's legs. Just a short hop over to Arborfield, near Reading, Berkshire for the local classic bike & car show.
I haven't ridden at all for the best part of 10 years, so was a little wary as I headed out onto the public roads. Thankfully the confidence soon came back & I really enjoyed the 10 miles or so to the show.
Not long after I arrived I was joined by Archie on his 1100 single sided, car wheeled street fighter thingy. We wandered around the show in the sunshine for a while, before heading back via Loony's workshop. Maybe 30 miles altogether, (hard to tell -my speedo's packed up), & I only lost 2 bolts! The rear exhaust/chain guard mount & a nut from one of the seat springs. Both now fixed.
It was great to follow Archie around the country lanes. The XS creates a whole cachophony of rattles at the moment, but they were drowned out by his popping & banging exhaust! :) The main rattle appears to be the unsupported front end of the exhaust baffles vibrating against the inside of the pipes. I might try a small collar of exhaust wadding's g around the front of each baffle to pack it out a bit. Other than that, it handles well, stops reasonably & sounds awesome when you accelerate hard :) very much like the old Triumphs of my youth. I'm pleased with it.
Obviously there'll be a long list of teething troubles over the next few months, but we'll work through them as they crop up. It's fun being a biker again :)

Post by: Manky Monkey on May 21, 2018, 08:58:29 PM
Absolutely fine, but then, we only covered about 30 miles.
The riding position's very comfortable. Standard position footpegs, (what I believe the young chaps call "mids"), with standard Yamaha rubbers, standard gearchange & brake pedal & slightly wider than normal flat bars. Very rideable.
I'd forgotten how much thumpy twins, rigidly bolted into a rigid frame, vibrate. That vibration gets transferred through the whole bike, so everything needs to be Loctited & spring washered -& still works loose.
I'd also forgotten the ritual of getting back from a ride & wiping the bike over, partly to clean off the road grime, but mainly to check for loose or missing parts. The joys of chops :)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 21, 2018, 09:07:12 PM
Had a quick look at the exhaust this evening, which seems to be the main source of the tinny rattling noise.
I pulled the baffles out & even without them, when you thump the side of the pipes, there's a buzzing kinda rattle. I'll try packing the unsupported front end of the baffles with a collar of exhaust wadding, but I think the 2 pipes also need to be tied together somewhere towards the front. So I have a plan. I'm going to buy a couple more of the exhaust clamps I used at the back end & use them to mount a new perforated stainless heatshield, covering both pipes. That'll fix the pipes together.
This is the bit I hate with custom stuff -the tedious job of finding the faults then adapting your original design to overcome them. I'm determined to stick with it though. It's close, but just needs some fine tuning.

Haven't ridden the bike since it's first outing, (under my command anyway), last week, as I want to sort the vibrating exhausts out before they end up fracturing.
So I've ordered some chrome exhaust clamps from the States & bought some perforated stainless sheet from Ebay, which will go together to make a bigger heatshield, covering g both pipes instead of just the top one, that will also tie the 2 pipes together to stop them vibrating.
The stainless mesh turned up today. I ordered slotted holes, rather than round, partly because I think it'll accentuate the long pipes & partly so it looks less like some hobby steel I bought from B & Q.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on May 29, 2018, 07:39:40 PM
Beaten to shape around a bit of steel bar with a rubber mallet. Can't do much more with it till the clamps arrive.
The perforated sheet was an offcut from a fabrication company. I've got a metre of it left if anybody needs some.

Hmm, well that didn't go quite according to plan.
Having bought the perforated sheet on eBay, spent a morning cutting & shaping it, then an afternoon delivering the offcut to Mr Stinkey down in Dorset, I'm not sure it's going to work.
The chrome clamps I want to use arrived from the States today. They're the same as the ones already fitted right at the end of the pipes. Trouble is, by the time I've welded mounting tabs to the guard & bred it to the clamps, it'll stand off the pipes by about 2", which looks all wrong. It turns an unobtrusive heatshield into a major feature & isn't what I'm after.
So now I'm tempted to flip the clamps over, to match the rear ones, & bolt them together, (I've just ordered some stainless tube nuts from eBay -round bar with a threaded hole down the centre), & leave it at that.
When I rode it the other week I could feel warmth from the pipes against my leg, but it wasn't close enough to burn.
Think I'll fit the connecting tubes when they arrive & see if it fixes the vibration problem.

Yeah, I thought the same Dave, but they're nice American heavy chromed jobbies. The main reason for the guard was to cover the clamps & provide a reason for them being there. All I'm actually trying to do is clamp the 2 pipes together to stop them "buzzing" along their unsupported length. I won't give up on the guard idea just yet, but it didn't look right standing so far off the pipes & I'm pretty sure the riding position doesn't actually put my leg in direct contact with them.
Years ago I was at a bike rally when a chop rider arrived with one leg of his jeans wrapped in asbestos type lagging & gaffer tape. Maybe not such a bad idea! :)

Lovely sunny Sunday morning. I'll nip down to the garage, fit the new clamps, tie some exhaust wadding around the front of the baffles with the stainless welding wire I've got & refit them, then take a ride out to the local monthly car & bike meeting this afternoon to road test it. Easy.
I've got a bag of 100 M6 Allen bolts -all 10mm too short to bolt the clamps on.
Using the bolts from the existing rear clamp to fit the front one, it pulls the pipes completely out of line at the back. I've loosened them at the cylinder head, but they're still not right. I'll have to loosely fit everything & gradually tighten it all & see how it looks.
I know I've got a reel of stainless welding wire, but can't find it in any of my 3 garages -spent an hour this morning driving back & forth across town to them all.
I hate this bloody bike. Determined. It to let it beat me, but I've never built anything that provokes me to tirades of shouted 4 letter swear words like this thing does.
I've shut the door & walked away from it for the day.

Sometimes that's for the best otherwise your frustration is compounded and then you are likely to screw something up. I don't mean just you. I think everyone has a limit.  :)

Beautiful day as well. Good to get out and breathe in some fresh air. Oh, of course you're a postie, you do that most days. Get back in that garage!  ;)  :D

Post by: Manky Monkey on June 04, 2018, 08:14:43 PM
...before I set fire to it.

Longer bolts bought this afternoon & a couple of 1.6mm stainless TIG welding rods given to me for free by Paul at Basingstoke Welding Supplies -hopefully flexible enough to wrap around a collar of exhaust wadding to stop the front end of the baffles rattling against the inside of the pipes, (unsecured wadding tends to get pushed down the pipes & bunch up at the far end).
Could've fitted it all this evening, but really couldn't be arsed. There's a local bike meet on Wednesday evening though, so I'll have a look at it tomorrow.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 06, 2018, 10:13:46 AM
So, back to the bike in a more positive frame of mind.
Loosened off the whole exhaust system, added the new clamps & gradually tightened it all again. Hopefully not under too much tension, so won't fracture anywhere -we'll see.
Tapping the side of the pipes, the rattle's gone. Great. Put the baffles back in -the rattle's back. O.K, so it's definitely the baffles against the inside of the pipe. Tried the TIG rod with some wadding, but the wire's too thick to twist around & secure the wadding & fit back in the pipe.
Tom's dropping off his safety wire pliers & stainless wire later, but I might try flaring the end of the baffle with a ball peen hammer first.
No, that's not an oil leak under the engine -it's a hole in the concrete garage floor :)


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 06, 2018, 10:21:33 AM
Took a look at the speedo, which packed up after the first 20 miles. Sure enough, the inner cable's snapped. Too tight a bend. Not a major problem -I'll move it a little higher & mount it off the mudguard bolts. Just need to make a right angled tab & buy a bigger size of the chrome exhaust clamp to sit the speedo in.
Deep breath, tackle the problems one at a time. Getting there, slowly.

Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 06, 2018, 07:09:18 PM
Unbelievable.
Set off for the bike meet. Stopped to fill up with fuel on the outskirts of town. Got about a mile down the Alton road & looked down to find the fuel cap missing. I definitely screwed it back in when I filled up, but didn't see or hear it go. Obviously, no sign of it on the road, (there never is when that happens, unless you spot it just in time to see a lorry run it over).
So the bike's back in the garage with the filler hole taped over until I can order a standard screw-in Harley cap to replace the very expensive pop-up one I used to own.
Oh, & the garage door lock jammed when I got back. Took me 20 minutes to free it off to put the bike away.
At what point do I give up?


Title: Re: Manky's XS650 Yamaha
Post by: Olds on June 06, 2018, 07:57:33 PM
Perhaps a chain on the cap isn't such a bad idea. You can borrow one of mine for a few days if you want to use the bike.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 06, 2018, 10:18:32 PM
Thanks Dave, but I seriously don't think I could resist the urge to beat it to death with a club hammer at the moment. I'll leave it in the garage till the new cap arrives, (eBay, 20 quid). Alternatively, box of matches, 50p.
Yeah, my old Bonny had a chain on the cap.
I've now had 2 offers from forummers to buy it for 2 1/2 grand. No idea what it's cost me over the last 10 years, but probably twice that. I hate it. I genuinely loathe the bloody thing. It's making me miserable.

Post by: Archie on June 07, 2018, 09:48:42 AM
No it isn't, it's just teethers. remember how much fun you did have in the sun.

2.5k? An engine in Andover was up at £800 the other day, so would probably be more like double maybe.

But as we said. This is a sunny sunday thing and if you get the bug to ride again, modern retro type jobby for mile munching.

Plus mines near on done, and if it's anything like the last one we can go breaking down, losing bits, running out of fuel all over the place. PLus throw tom into the mix and we can be a right old rabble of roadside wrecks.

Maybe a blast into london to assembly chopper show next month will give you something to aim for


Title: Re: Manky's XS650 Yamaha
Post by: Stix on June 07, 2018, 10:11:59 AM
2.5k. Noooooo, I like most monkeys have followed your trials and tribulations during this build and believe it is worth as Archie said close on double that amount, it is a running taxed and mot'd bike with just a couple of small faults that are annoying you, a couple of evenings should see it finished and ready to ride. Ride it and get the shake down out of the way, it is an older bike and has been heavily modified so is not going to be the same as a newer factory model and will always want some-thing tweaking or tightening back up, but these things can only be sorted once it is being ridden and these little things found.
If you give it away now you will regret it for a long time, how will you feel about if when you see it at a show or pics on here with a new owner enjoying the fruits of YOUR labour?? Archie has suggested a newer bike to use as a summer fun thing, plenty about that can give you some smiles and let you get out on a sunny day going back to the Yam when you are in a calmer mood, my own bike/trikes have not been touched in 3years as they have been in storage or traveling halfway round Europe but no way do I want to sell them even if it will be a pain to get them registered for use here. Don't give up on your dream Andy or you will just have nightmares about it once it is gone.

It was my asking price. No idea what it's worth.
Thanks for the input chaps. I know there'll be teething troubles. Everything I've ever built has had initial problems -but this one really has turned into a battle of endurance. I'm not enjoying it at all at the moment. Even if I sell it, there are jobs I want to finish though, cos it'd bug me to let it go half done.
Back in the garage again today though cos the chrome exhaust clamp I ordered yesterday afternoon arrived this morning, (damn, those Posties are good). I'll use it to mount the speedo to the fork leg, a few inches higher than before so the cable will have a smoother route & hopefully won't snap again.
So I knocked up a quick bracket this afternoon that bolts to the mudguard mount & wraps around the forkleg. I'll get it powder coated while I wait for the new cable to arrive & will also have to shave the unwanted lug off that the speedo previously bolted to.
I also no longer need the hugely expensive right angled drive fitting I used before. It's the same as the one fitted to my truck speedo though, so at least I have a spare.

It was Tom, using the spare set of garage keys to take some measurements off the bike for his own. So I'm still stuck with it.
New fuel cap's arrived. I actually prefer it to the previous  one. It's a clicky ratchety thing on it so you can't overtighten it. We'll see how long this one lasts.

Rode the bike 2 miles across town this morning to my other garage, to work on my truck. Made it there & back without losing any more parts, which is a result.
While I was there, I cut off the unwanted brake caliper lug on the left forkleg, which the speedo had been bolted to, & started filing it smooth. The engine's absolutely filthy, with 38 years of ingrained grime on the aluminium cases. Need to start scrubbing it clean I think.

Yeah, it's not a show bike -it's got an oil leak from the head gasket, although not enough to warrant taking the engine out of the frame to fix it. Anyone tried those leak stopping oil additives?
I'll just scrub the ali with some Scotchbrite every now & then. Eventually it'll get clean :)

FYI - A trusted mechanic friend years ago described the “turd” he found in the sump of a car following the use of an anti-oil-leak additive.

Things have hopefully moved on.................

Current additives appear to try and deal with drying out / shrinking of rubber /  neoprene seals and O-rings.

probably dried out o rings. XS's are prone to head and oil feed/drain weeps. May get worse, unlikely to get better. Live with it or fix it.

So, I had another go at riding to the local bike meet this evening. Went with a couple of mates from the Post Office, one on a new Triumph Bonneville & one on an old ex Army 350 Harley trail bike thing.
The XS goes well when accelerating & handles fine, but has developed a misfire/backfire when sharply decellerating. The exhaust note also seems to be more "plop, plop, plop" now than it used to be, (that sound Jap bikes tend to make when running short pipes). At one point on the ride there, I slowed for a corner & suddenly lost all power, just for a second, followed by a huge backfire as it cut back in again. Electrical? Fuel? No idea. I'm rubbish at fault finding. Tom said it popped a few times when he took it for the MOT. The bike shop fitted fresh plugs & it was fine -which would mean what? Running rich?
On the way back several cars flashed their lights at us & sure enough, there was a Police car tucked in a side road with a hand held speed gun. We trundled gently past, with my bike popping & banging like mad. Further up the road, I opened it up again & it was fine, so I'm guessing fouled plugs.
Otherwise, a good ride. Maybe 20 miles, only marred by the Army bike getting a slow puncture -we had to stop in a garage to inflate it so he could get home.
The front brake caliper is working fine, but rattles. I'm wondering if that's the annoying rattle I thought was the exhaust.
Still not feeling much enthusiasm for the thing, but trying to work through the teething trouble stage without hitting it with a hammer.

Right then, gasket paper ordered, Hylomar gasket sealant, (yeah I know the carb manifolds shouldn't need it, but bet they will), new exhaust seals ordered & Gun Gum sealing paste bought.
Checked the plugs & they look fine.

The front brake caliper's a very sloppy sliding fit on it's carrier. It's got all the shims it's supposed to have, so not sure how I can quiten it down, other than lots of copper grease on the sliding surfaces.

Not just popping on the over run, but just generally at low speeds. I'll seal everything, then at least I'll know that's not the problem.
Just spent an hour or so filing, sanding & polishing the fork legs. Unwanted caliper lug, (used to mount the speedo), gone.

Exhaust dismantled, new gaskets fitted in the cylinder head & everything refitted.
Front brake caliper dismantled & all sliding surfaces copper greased, then refitted.
The gasket material for the carb manifolds arrived, but I ordered the wrong stuff -thick, rigid composite sheet, rather than paper, so have ordered more.
Haven't had a chance to try it to see if the backfire's been cured though.

Been feeling lousy for the last few days. Thought it was just the heat, but apparently there's a bug going round at work. Haven't looked at the bike this week but the gasket material arrived the other day so I've just cut a couple of 1mm thick gaskets to fit between the cast ali' carb manifolds & the engine. The carb bodies have O rings to seal them against the manifolds, so I left them alone. Didn't bother with liquid sealant in the end.

Took s ride over to Guildford this afternoon. No speedo fitted yet cos I'm waiting for the mounting bracket to come back from the powder coaters, but Google Maps told me it was bang on 40 miles each way, so an 80 mile round trip, stopping off at JackHammer hotrod shop in Farnborough on the way.

Post by: Manky Monkey on June 22, 2018, 11:12:48 PM
Yup, I seem to have fixed the popping & banging from last week, but now it's developed an oil leak from the other side of the cylinder head.
It also got very hot & irritable riding through the middle of Guildford's Friday evening rush hour, stalling several times & getting a bit clunky when changing gear. Having to paddle it to the side of the road & kick start it, with a queue of car drivers behind me, revealed a talent for swearing I didn't know I had.
I was heading for a circular "Moon Door" in a road in Cranleigh to take some photos, but the Cranleigh road was shut & I eventually gave up fighting my way around the town in the heat & headed home. I stopped for these pics on the way back.
The bike ran quite happily once I was back out on the open road, but doesn't like slow town traffic when the engine's hot. I've already ordered new inline fuel filters as they look pretty mucky already, but any other suggestions? -apart from "Don't go to Guildford"?
After only a few miles of motorway speeds, my bum was already getting numb. This isn't a long distance hauler.
I'm trying really hard to like the thing, but maybe I'm just not the biker I used to be.

Your out and riding on a sunny day..I can only dream of that ,like so many of us ? I'd be grinning like a Cheshire Cat and so what if it breaks down..we live on an island, never far from home or help ::)
You should pop into to some fellow monkeys and show off the the Bike with PRIDE mate.. 8)

Yup, I seem to have fixed the popping & banging from last week, but now it's developed an oil leak from the other side of the cylinder head.
It also got very hot & irritable riding through the middle of Guildford's Friday evening rush hour, stalling several times & getting a bit clunky when changing gear. Having to paddle it to the side of the road & kick start it, with a queue of car drivers behind me, revealed a talent for swearing I didn't know I had.
I was heading for a circular "Moon Door" in a road in Cranleigh to take some photos, but the Cranleigh road was shut & I eventually gave up fighting my way around the town in the heat & headed home. I stopped for these pics on the way back.
The bike ran quite happily once I was back out on the open road, but doesn't like slow town traffic when the engine's hot. I've already ordered new inline fuel filters as they look pretty mucky already, but any other suggestions? -apart from "Don't go to Guildford"?
After only a few miles of motorway speeds, my bum was already getting numb. This isn't a long distance hauler.
I'm trying really hard to like the thing, but maybe I'm just not the biker I used to be.

You know you like it, just look at how many photos you’ve posted!! ;D

I have a couple of suggestions....first, get yourself a "Gel" insert for the seat, may not be quite as pretty as it is now, but oh the relief!! :D.. second, you need to factor in the dreaded advancing years!! honestly! as, by your own admission, Mr. M, you have been off 'bikes for some years, so getting rider fit, to cover distances, will take some time, not helped by the time period between the previous time you rode, and being a good deal senior, aka "older", than you! I speak from experience, unfortunately :P...but I wouldn't swap my gel saddle for 'looks', anytime, I was out today on my Suzuki and by the time I returned I thought I had colliers "white finger"....ho, hum...It don't come alone...Morrag

Maybe an inflatable cushion for long trips? :)
I'm determined to keep plugging away at it & fixing any problems that crop up, but I'm struggling to get enthusuastic about it. It's just hard work at the moment.
Any suggestions for the buggering about when it's hot? Felt almost like fuel evaporation -when I opened the throttle to pull away it'd kinda gasp for breath. Too quick on the throttle & it'd stall. Maybe a spacer block between the aluminium carb manifolds & engine, as used on Reliants? What are they made from & how thick would they need to be? Maybe Burlen Fuels, who make Amal carbs, sell them?
Once it was out on open roads again, with some airflow to cool it down, it seemed better. I'm struggling in the Summer heat at the moment too, so maybe it'll be happier when the weather cools.
No idea what it should be doing to the gallon, but the tank"s probably about half full after 80 miles or so & I think it's a 2 1/2 gallon tank.
Nothing fell off on this trip, so it must be getting better :)

Burlens list a similar spacer, made of Tufnol, for 8 quid, but it's a nicer looking product. They stock 3 bore sizes, 28, 30 & 32mm. Can't remember what my carbs are, but think they're 930s, so 900 series, 30mm bore.

Insulating washers / spacers as suggested for your Amals would be a wise move to reduce the thermal path, just look at what Mr Yamaha had fitted as stock for his Mikunis when he sold the XS new.

Mr Slam & I were stuck by the roadside many moons ago as the mid 1920’s Raleigh he was on (with a direct brass coupling from the intlet to the carb) had the petrol boiling in the carb, a chinwag and 20 mins later it had cooled enough to restart.

On your Frog, you could try tickling (heh heh) the carbs if it does the same again to put a bit of / more juice in the float bowl. What could possibly go wrong!!

Gel seat covers – gentlemen of a particular age that I know who ride rigid bikes say they’re the poddle’s privates and well worth investing in.

I did tickle the carbs when the bike stalled in traffic in Guildford, (it was properly gridlocked over there with no room to even manouvre through on a bike). They took a couple of squirts to fill the floatbowls, which is why I suspect evaporation or muck in the fuel lines. Seperate feeds to each carb though, so at least one should run O.K
Mr Slam & I have discussed the merits of gel seats before. I thought the springs would be enough, but obviously not. If I can resist the urge to beat the bike to death with a hammer, I think I might have to get the seat re-upholstered, (again), with gel instead of foam.

How about borrowing one of those gel covers that fits on top of the original saddle and is held down with straps to see how comfy it is.
If that does the biz, you can keep your nice original cool looking saddle as is, use the gel pad for longer rides (which can then be removed when you’re parked up), and leave the pad at home when you’re doing shorter rides.

http://www.motorcyclegelpad.co.uk/classic__vintage_saddle_gel_pad.html

Sorted!

If you’re feeling that way inclined, you could always go for padded gel shorts the bicyclists use that fellow Monkey's have mentioned............. but you may have to learn to swagger a bit more when walking.....  :-\

Thanks. I keep meaning to phone the upholsterers & ask if they've worked on any gel seats. I don't know if it comes as a sort of sealed bag that you can't alter, or if it's actually a gel that you could cut to shape.

You can buy it in sheet form and cut it to shape. It comes in various thicknesses, or you could buy a detachable one to see if it helps before messing around with the seat (again).

I saw a bantam trials bike with a seat made from a speedo swimming float cut to shape covered in leather after sanded edge profile, ok stood up much of the time but it was surprisingly supple probably more cushioning effect than your saddle, they are £5-£10 any ports shop/

For a fiver that'd be worth trying I guess. Need to do something or I won't be travelling far on it. I'd like to take it to the Detonators car club bbq in South London in a couple of weeks, but that means a trip right around the bottom of the M25.

When was a kid used to get old gents bikes with like thick saddle leather seats, some were like a frame springs and all that, but some were a basic spine and surround with the thick leather rivited to the edge frame the leather itself was like the comfort aspect if you like, they were a lot better than the typical spring stretcher type with thiner cover over. they did racing bike saddles same style, i guess a\ saddler could do something on a simple edge frame to your seat profile, have no idea what it would cost mind.

I was discussing this with Tom earlier, (he's borrowing the bike one evening next week). It's not the bumps, it's sitting on the motorway at a constant speed that creates a vibration that numbs your bum after about 20 miles.
Heat insulators fitted on longer studs.

Did you put a gasket between the spacer and the manifold ? Carb to spacer would probably be OK with the 'O' ring

motorway at a constant speed that creates a vibration that numbs your bum after about 20 miles.

My A10  cafe racer seat was the same. Rubber mounting it helped a lot but in the end I changed the seat for a std. one. These days I need a very comfy seat.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on June 30, 2018, 07:44:12 AM
No gasket at the moment Dave -the spacer has a little bit of flex in it so I'm hoping it'll seal on it's own. Easy enough to fix if it doesn't though.

Post by: Manky Monkey on July 01, 2018, 07:30:16 PM
Took the bike out to a local classic meet this afternoon. Maybe 10 miles each way.
No real problems. The clutch was dragging a little when I arrived so I adjusted the lever before riding back -then it rattled against the engine casing a couple of times as I changed gear on the way home. Tom's using it one evening this week, so he can fiddle with it again if it plays up.
Other than that, it seems alright. Nothing's fallen off & it's fun to blat around country roads on.

For Christmas one year, think I'd be about 11, I got a brand new Chopper.

Was amazing, nut cracking gear changer and everything, in red.

Only years later I appreciated how much my poor mum & dad must have had to sacrifice to get it for me.

My Bessie mate, Dave got a second hand butchers bike complete with wicker basket and a centre stand. The centre stand was bigger than anything I had ever seen, and must have weighed as much as the whole bike.

Being my best mate we shared the bikes, seemed like the decent thing to do at the time.

Thinking about it we lived at the foot of the Pennines and, consequently , it was uphill to get to most places.

Needless to say I haven't shared much since. :D

S-o-o hot :( I'm really struggling in this heat. Don't want to do anything, so vehicle work has come to a bit of a halt for now. I was in the bike garage last night when Mr Baychimp arrived. We chatted for a couple of hours & I went home with nothing achieved -my fault, not his :) Today I re-fitted the mini speedo on it's powder coated bracket, with the new shortened cable, but that's about all I've achieved recently.
I plan to take the bike to a classic vehicle show in Surrey on Sunday, but need to make some more paper gaskets for the carb manifolds & readjust the clutch lever before then, so will have to spend some time in the garage tomorrow afternoon.

Speedo doesn't work -why did I even hope it would  >:(
Well, I covered around 100 miles on it today, in absolutely blistering heat. I could feel the sweat trickling down my neck as I rode. Have to admit though, it did good.
A blast up the M3, then through Guildford to Clandon Park, where I used to live with Tazet, for the 8th classic vehicle show. No running problems, though it took a couple of kicks to fire it up once it was hot. No popping or banging or struggling to run in heavy traffic around Guildford, so the inlet heat insulators & gaskets seem to be doing the job.
After the show I carried on to the village of Wonersh, to take a couple of photos at the entrance to a posh private road over there.
Not quite such a numb bum on the motorway ride home -so maybe I'm getting used to it. It's the continuous buzzing vibration of sitting at a constant speed that does it. It was a lot of fun blasting around the Surrey countryside though.
One hiccup on the way back, literally at the end of my street, when it stalled as I left the traffic lights. I need to blip the throttle just before I pull away when it's really hot, so I assume it's fuel evaporation? I'll give it that one though -after all, I'd just ridden back down the motorway in the hottest weather imaginable.
Still getting a loud vibrating rattle in the mid rev range, which I can ride through & it goes quiet again. Still think that's the baffles inside the pipes. A few small areas of paint & indicator wiring that need tidying up, but nothing else has broken or worked loose -yet.
I'm on holiday next week, so maybe Tom can put some miles on it, but I plan to take it to the Detonators car club's BBQ when I get back, (yes, they have bikes there too), so that will mean a trip around the bottom of the M25. Motorways are O K, but it's definitely more suited to A & B roads.
Overall- today was fun. :)

On the subject of visors, I bought this "bubble" visor at a hotrod show in Holland a couple of years ago. They're trendy with the retro hipster biker brigade, (I guess that's me). I didn't really expect it to be much good, but it's the best one I've ever tried.
They come in different colours, even Mad Max style mirrored finish. This one's got a graduated green tint, but you really can't notice it when you're wearing it. I've tried all kinds of goggles, from the traditional Halcyon split glass ones to tiny swimming types with interchangeable strap or sunglass style arms -but they all give me tunnel vision & steam up as soon as I stop moving.
The Halcyon ones are so big the rim of my helmet pushes them down my nose. Then there's the question of wearing the strap over or under the helmet. Over the top & you risk them popping over the top, (no retaining clip on the back of my lid), plus they then don't fit tight to your face, with gaps around the edge. Under the helmet & the strap gets pressed into your head & gets really uncomfortable.
I've tried wrap around shades, safety glasses, all kinds of stuff, but this is the best by far. Great all round vision, no rattles, no wind noise, doesn't catch the wind & try to pull your head off. The only down side is I look like I'm wearing a goldfish bowl. I can live with that -I'm a trendy hipster :)

I remember the early bubble visors, swept the rain off great. One night howling across Dartmoor, looked back to see if my mate was still with me, and bang, it was gone ! Hit him straight in the face. Luckily it quickly went into the dark. When I finally summoned up courage to stop. He was in fits of laughter. The shock had him for a few seconds then the relief hit him. Luckily he didn't hit me ! Next morning big bruise on his nose. Oh, how we laughed  ;D ;D The days of screaming two stroke Kawasakis. And smoke galore

I remember selling lots of the Stadium bubble visors in the 70's. Either clear or yellow, they had a hinge arrangement and an alloy band that clipped to the helmet studs. Raising the visor at speed wasn't to be recommended. ;D

It's an American made Biltwell helmet, pinstriped by PD's nephew. I'd like it signwritten to match the Pop doors when they're done, but painter's etiquette says it's not the done thing to wipe off one artist's work & replace it with another.
I like these Bell helmets, but most open faces are heavily padded so tend to sit very high on your head. The Biltwell's nice & snug fitting.

O...K, I'm done with this now.
I'm currently sat on the side of the South Circular, waiting for the AA. I was cutting across the middle of London & the bike's been popping & banging & stalling at junctions & finally died. Sooted up plugs, or ignition, or fuel - who knows. I no longer care. Just not interested in it any more.
My biking days are over.
No, I'm not sat there. I just stopped there earlier :)

So sorry to read this Andy, I can only suggest you put the bike into a competent shop that knows yamaha and ask them for a quote to check just what is wrong with it and is it worth spending the money on it to get it  running 100% might not cost as much as you think but it does sound like a weak spark causing the problems as the carbs have bees set up already.
If you sell it it will be a sad day for those that have followed the build but I can understand you frustration with it. >:( >:(


Title: Re: Manky's XS650 Yamaha
Post by: Archie on July 22, 2018, 02:19:49 PM
Got a set of standard carbs here if you want to try those? They were off a running bike so could be a way of eliminating one possible problem


Title: Re: Manky's XS650 Yamaha
Post by: terry t on July 22, 2018, 04:32:31 PM
Like Archie said Andy Try the carbs he got. that the only way to tell if its a fuel related problem.

Looking a your carbs on the bike float bowls don't look like they hold much fuel. it could be there not man enough to run the bike properly in this heat

were they balanced and what jets did you have fitted

Mr M, I understand that you are running new Amal Concentric's on your machine, however, try the offer of a pair of "standard" carbs. first. Me, I go the opposite route and run my Trumpet on a Mikuni as opposed to the standard Concentric, why, I have found Mikuni's to be a better carb. over the years, so it's worth a prod? I doubt that it's ignition woes, from the symptoms, but....never say never. I do have reservations regarding your exhaust system's back pressure characteristics though, Morrag

Already sold, my friends.
Mr Coppersmith offered to buy it a few months ago, but local guy Tom, (Tom PRS on the forum), stepped in & finished the build & MOT'd it. He matched Steve's offer & in view of the work he did & his determination to keep the bike in the local area, it's going to him. I'm sorry Steve, but I hope you understand. Nothing personal my friend.
So I made 2 phone calls from the roadside in Putney, one to the AA & a text to Tom. He's on holiday in Tenerife, but immediately said Yes. We'll sort the details out when he gets back.
I really am done with this now.

It did start to feel like I was struggling on with it more for other people's enjoyment than my own in the end. I kept getting told you can't sell it, you mustn't sell it -well yes, actually I can.
When it died, I got off it & thought I can't even be bothered to get annoyed about it. I've been a life long biker, but circumstances change, lifestyles change -I've changed & now there seems more negatives to riding bikes than positives. We all chop & change projects all the time. Life goes on.
I had a break from bikes for a few years, came back to it with a Speed Triple with Sara, had another Speed Triple when I was with Tanya, then started building this. Had another 2 girlfriends in the meantime & moved house again. Different way of life, different group of friends, nobody else to ride with, not interested in the traditional bike rallies & shows I used to go to anymore. I think I've just got older & can't be bothered with it all. I still have an interest in bikes but this one has finally proved I've lost the buzz I used to get from riding. Not sad about it -I've had 4 decades of biking & survived reasonably intact, with some great friends & memories, but I really am done with it now.

The XS is still sat in my garage, awaiting collection, so while I was grabbing some tools from there this afternoon, I checked the plugs. Very sooty.
Cleaned them & it fired up first kick, though it was a bit hesitant when I blipped the throttle, but I think it's low on fuel.

  I thought it was an awesome bike and its so close to being complete too, i can not say i expected you to move it on but its clear to see you had not to put too finer point on it ENOUGH!
   So move on my friend its the logical thing to do, but please let time be the decider on if you give bikes up or not from now on.
   You feel done with them now but emotions are a funny old thing dont let them rule you man.
 Here you go! Ill plant one little seed of doubt on you leaving bikes behind. Deep down could you just have a glimmer of desire for another triumph triple?   ;D
   Whatever you do enjoy it i think thats what went wrong here, You stopped enjoying it  thats all, i think the fact it had two wheels was very much a secondary issue.
  Move on mister but dont move out not just yet in any case old age will decide that for us all in the end and thats something none of us has a say in anyway.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 17, 2018, 07:44:04 PM
Thank you.
The bike's still sat in my garage at the moment. Local guy Tom is buying it but needs a month or so to come up with the money. I've got someone coming to collect the bike lift this weekend, but still got other stuff in the garage at the moment, so there's no huge rush to move it on.
The last time I rode regularly was ...14 years ago. I had a Triumph Speed Triple & a girlfriend who lived 30 miles away & had just got into biking. Neither of us had a car so we rode our bikes everywhere, all the time.
A couple of years later I'd moved in with another girlfriend who liked bikes but didn't have a licence. A local bikeshop had a Triple for sale identical to my previous one, so on a whim, I bought it. My lifestyle had changed though & I was a bit older & it just wasn't the same. I think I rode it half a dozen times in a year.
Fast forward a few years & I'm single again & a bunch of younger local mates were all getting into the chop scene & I thought Hmm, I wouldn't mind another one.
Built it, ridden it, not getting the same buzz I used to.
I think I've just grown out of it all. Can't wait to get my hotrod finished & drive that, but 2 wheels really doesn't do it for me any more. It's not a spur of the moment decision, it's been coming for a long time.


Title: Re: Manky's XS650 Yamaha
Post by: The North on August 17, 2018, 08:41:06 PM
 Well that sounds like its a reasoned move leaving bike behind, and least ways now you have  more time and fresh funds to throw at your pop or another project if one takes your fancy.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 18, 2018, 08:11:03 PM
No more projects! :)
I've got a friend coming from Libcolnshire tomorrow to collect the bike bench, so I stopped at the garage this evening to check it was ready & working O.K.
I started the bike while I was there. As usual, it fired first kick & sat there happily chugging away. I'm really pleased with the way it turned out, but even as I sat on it with the engine running, I had no desire to ride it off up the street.
It might sound a bit pretentious to talk about having an emotional connection to a vehicle, but I don't. I don't feel anything for it at all. It was the same with my previous bike, the second Speed Triple. I think that tells me all I need to know. I've been just going through the motions of bike ownership for the last few years without really enjoying it any more.


Title: Re: Manky's XS650 Yamaha
Post by: Manky Monkey on August 28, 2018, 10:23:37 PM
Tom needs a little while to come up with the cash for the XS & I'm not desperate for it, so for the time being it's still in my garage.
A local pub, 6 or 7 miles outside Basingstoke, has started a monthly charity bike night, so I took a ride over there this evening.
First time I'd ridden it in the dark. The lights are fine, it fired first kick, even with an audience as I left the pub, (normally guaranteed to let you down at that moment. The guy who left just before me on a brand new Kawasaki toppled over at the junction at the end of the street, in front of the onlookers), & it ran absolutely fine there & back.
I'm sure it's doing that just to annoy me :(

Hmm, kinda. It was a nice evening for a blat, even with a few spots of rain on the way home, & I only rode a few miles each way so not long enough for it to get uncomfortable or whatever.
I'm happy to ride it locally, but wouldn't say it excites me.
Pleasant, but no real buzz.

Post by: Manky Monkey on October 01, 2018, 05:47:27 PM
So. Another chapter closed today.
Having spent bloomin' years of my life building this thing, I found I just didn't enjoy riding it. Not just this bike, but 2 wheels in general. It just doesn't do it for me any more.
After a lot of soul searching, I decided to sell it. Local guy, Tom, who stepped in & finished the last bits & pieces when I lost interest in it, really wanted to buy it but just couldn't raise the cash. Our own Mr CopperSmith has tried to buy it several times & today he finally succeeded.
He arrived with a van & the Junkyard Frog is now tucked up in his garage in Plymouth. I've already swept the rented garage out & handed back the keys. Time to hang up my helmet & move on to other things.
I hope it brings you lots & lots of smiles Steve :)
