I've tried these several times over the years, but never had any success with them.

Strangled the hell out of my A pick up

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!

I made these for my TL1000 race cans cos they were thumpingly harsh. They are only 8'' long but work really well for reducing the hash noise level. Even went through M.O.T. with these fitted!

I read some where not sure what site though. they made a up disc a bit smaller than the exhaust pipe bolted it near the end of the pipe that reduced the noise
Has any one come across this?

That's pretty much what I did, that really good picture I sent you Andy  
I made some inverted cones that went from full inner diameter reducing down to about half, made a world of difference and was actually more free flowing than the drilled tube type

  I'll probably go with a metre of the smallest bore perforated tube I can find, (looks like about 30mm), with a single wrap of wadding around it & see what that does.

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" I speak as one who has made most, if not all, of those 'stumbles!' so deep breath and....Morrag

I wonder if the weather is a factor? I struggle to find the motivation this time of year.
And every snag seems to be ten times worse. Keep at it monkey it will soon be summer, just saying that makes me happier 

[minimutly]

Good words from morrag there, take heart from comments on the quallity of what you've produced so far, and take it one step at a time.

[stinkey]

I agree with Morrag Andy, plus doing to many projects does tend to drive you crazy but us rodders all do it ?  ..I'm sat here in hospital waiting on my OP tomorrow ..and dreaming about my latest project ..I had intended to make the frame myself,but decided to have my good buddy do it for me..(Attitude Customs ) after waiting 3 years for the right time / moment ?
So to say I'm exited to get out of here..

[stinkey]

That's not me on the chop,and I built the front end

[Stix]

Best wishes for tomorrow mate and with the amount of space in that room why not get the bike delivered there so you can tinker for a couple of days

Hope it all goes well for tomorrow

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?

[spanners]

i think the only drawback with PMA, is the initial cost     otherwise i would have bought a PMA kit by now
