Suspected Cam/Timing chain chatter

[celticdog]

deffo sounds like a big end if you got gold powder in the oil its 100 percent big end starter clutch dont make a noise clutch basket rattle only happens at idle and if you pull the clutch in it goes away deffo time for a strip down if your very lucky it will only be shells but with you running it allot more than likely their will be damage on the crank you tube rod nock and listen to it bet it sounds the same as yours rod knock is big end failure

Yep that deep knocking noise means you have con rod movement, could be at either end but most likely a shell bearing at bottom rather than at the piston pin. You'll know if you've damaged the crankshaft, If you've flared up a bearing surface the bike will feel wobbly as well as noisy, I don't think you're there yet but I wouldn't rev her too high.
