just seen your other posts ,when you remove compnut inspect it as my evo one was streched and you could see it on the shaft of the nut it was about 4mm longer than the new one,but in saying that i have replaced whole comp assembely aswell and it is still noisy ,as said before noisy fuggers

Hey bowsaw-- Ive had my componsating sprocket quite a few times on my fxr--have never had to take the clutch basket of----slacken off the tensoiner and you should be able to slide the compenater and primary chain off--it is tight ---softys might be different but i doubt it--cheers Grim

Hey bowsaw,don't totaly disreguard it being ya chain.Now you've got the cover of have a look for signs of the chain slapping the inside of the cover (where the bolts go through).Mine developed a loud knock with less than 200 k's on the clock,it sorted itself out after another couple of hundred.Apparently it can take a while for the tensioner to jump up a notch.Cheer's WAZ!!
