I have an 05, 955i, when i pull away I get a clunk sound, sounds like its coming from my left foot area, had new chain, cush drive and checked all bolt etc but still doing it, its sounds like a sproket loose and taking up the slack, when i slow down it does the same as if the slack is going back if you see what i mean, have anyone else had the same problem, cant find out what it is.
Can I assume the chain is not slack? Check the swinging arm bushes.
checked chain and swinging arm bushes
front sprocket worn or broken teeth/badly hooked up,splines worn on sprocket shaft or sprocket if its an after market one allowing play before drive is taken up
Take the front cover off and check the sprocket. They have been known to work loose.

:iagree My money is on the sprocket too
You didn't renew the sprockets at the same time, false economy mate.
If you are still :icon_scratch: you can bring it round, I'm only about 20 minutes from you......
I would bet on a problem in the rear wheel cush drive. Something binding. Get it up on the center stand if you got one put it in gear and jerk the back wheel around until you locate the clunk
Tried all of above, new cushdrive fitted at a well known bike shop in Norwich, (not a triumph dealer may I add) which checked everything, had it in twice, ended up saying it must just be a Triumph thing, The chap who is 20 mins from me, I would be interested in popping round sometime, if you email me your details to butchoboy@aol.com, Thanks

Haha John boy looks like you've got the short straw :icon_biggrin: 'The chap who is 20 minutes from me'!!!! that's a cracker :icon_rolleyes:
Wonder if the cush drive is re-assembled correctly and the sprocket carrier is in the correct position in the rubbers. Chain too tight and found the tight spot!

Also check the front chain rubbing block, hidden right behind the left footpeg on one of the engine mount bolts, mine had swivelled and worn right through to the spacer it sits on.

Ditto,
Id also look at the sprocket carrier bearing.
Butchoboy...did you end up getting this resolved? Mine has started doing it and I'd be interested to know what the source of the clunk was.
I'm curious as well. Mine does it as well and I've checked/replaced all suggested parts.

rear shock mount?
a few posts have told the tale of binding
drag the rear brake as you take off and see if it changes anything
does it make the clunk when changing gears? or only at takeoff and stop?
