Anyone got any thoughts about this?
My Griso 8v has never been quite right since the cam follower recall. It was noisy on the right hand side to start with, and it took several stays at the dealer to eventually sort it. It had what basically sounded like tappet noise, which got worse as it warmed up. I think the root problem turned out to be end-float on the right hand camshaft, but various things were tried before it was sorted.
Now it's noisy on the left. The symptoms are a regular noise - not a knock - more of a "ker-dink....ker-dink!". It is engine speed related, and has a period of about one second at tickover of around 1200rpm. This also gets worse as the engine warms up. And then, after about 30 or 40 minutes riding it will suddenly get very loud indeed on the left - rapid loud hammering tappety sound - which can last for about 30 seconds or so before fading back to the regular "ker-chink".
The dealer has so far not been able to trace the problem, having stripped the left side twice, and taken the engine out once in order to repalace the cam chain. The wheels the cam chain run on have also been replaced, as have the tensioner and blades.
