Hi all, so my fazer has had a noisy, clackety cam chain for aaages but out of the blue decided to quiten up on the way back from Assen BSB. Thing is, now I notice a relatively loud tapping noise coming from the head which rises and falls with engine revs in a similar way that the cam chain rattle would. Now I know that when valve clearance wear they become tighter and therefore less noisy, but can it cause the bucket/shim/cam lobe to make a rattle?? It is definately NOT cam chain and does quieten down significantly when warmed...any ideas foccers?
