hello! I checked the cams when i bought the bike, i could not find any signs of wear. aproximately 1000km afterwards i discovered small shiny chunks of metal in the oil screen. Turns out that cam follower bearing is chewed away along with the camshaft on the exhaust side. Unknown when camshaft was last changed. Im now wondering what caused the problem. Is this a common problem? or could I blame the cheap oil I was running or maybe an oil pump problem? would a complete rebuild of the engine be necesary? Or am i looking at just replacing the cam and follower bearings. I can imagine those metal chunks is having a lot of fun inside the engine.
