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.

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? )

I`ve got a pair of those Amal carbs sitting here doing nothing. Did start to fit them to my virago but had a new standard set land in my lap so took the easy route.

Now you tell me! Typical.
I bought a pair of 26mm ones from Ebay by mistake -too small. The latest set are 30mm.
So if anyone wants a pair of 26mm mark 1s, taken off a 1972 Triumph Daytona 500cc twin, they're going for 30 quid the pair.

Did you not see the effort trying to get mine running again today. And when it folded it sidestand up, fell over where i caught it and trapped the bridge of my toes / foot between the frame rail and ground. I swear it was in the air balanced on my foot. |

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
