Eveything has a life cycle. Just a strange one for me, never seen in all my moto years. Cause, most likely a rock got caught up in the works. CS sprocket, upon post ride inspection found one tooth of my Renthal (just for reference) front sprocket gone, cracked right off. It's got some time on it (hours?). I have no issues its just an FYI post, will replace it this week. Just that I never seen this particular fail ever before.
I was at a club race and a guy with a 4 stroke Yamaha said his sprocket was leaking. This I had to see. The sprocket had no teeth left on it. My guess is it was leaking from the counter shaft.
I have seen them all (the teeth) completly sheared clean with just bumps left on an occaisional badly maintained bike. And of course the worn and hooked teeth as well. It was just an odd one for me, but like motosportz said hes seen numerous teeth sheared with some remaining that too sounds like FOD (from a rock or something hard like my deal). It is just a conversation post, for interest thanks for responses.
