I assume you are talking about the cam chain. On the new 70deg engines, they are pretty noisy. I put in a Dirt Trick Cam Chain Tensioner and it is a tonne better than stock....way less noise.
The bike is a 99 400fc.This bike may have 50 hrs on it.The guy I got it from said he never rode it much it just sat in the barn.But when I ride it It make's a lot of slapping noise just after you crack the throttle then stop's when I nail it.
Change it before its too late, then make the following changes:
If you can change the timing sprocket to a steel one, the alum. is no good.
Last, see owners docs and make a new tip of the chain tensioner (longuer one), so the chain last longuer or change the guide but don't know if its possible on the 99 engine.

I have looked at it but always been too busy to try it. the pre 2001 engines have the 2001-2003 blade but upside down! I think it wouldn't work from looking at it but need another look.
look, at £5.80 it isn't going to break anybodies bank now is it!
