CATOR15JJ

Thanks, I will have a look. Its strange, quite loud but only when you snap throttle on an off. dont notice anything strange when riding. and gears are perfect so hopefully nothing to worry about.

Hi Can any one help as this is all new to me. I have a R1 2001 5JJ which is my 1st bike with only 8000 miles on and is mint an rides perfect. It has a rattle or cracking noise. this only happens as the revs drop when reved stationary. dont notice it when you go along just stationary. dosnt seem as bad when warm. Dosnt do it when you rev it gently and let the revs die slowly just when you give it a good rev and throttle snaps shut again. Sounds like its coming from poss the gear box area or exhaust. I was wondering weather it was the clutch or exup valve or if this is normal???? Any advice appreciated.
