Looking at a used engine with 10,000 miles on it for a pretty decent price. Seller says that the chain broke and balled up snapping the lip surrounding the output sprocket off. He says there is a slight tick when the bike is in motion now, although it can't be heard when being spun by hand. There is no play in the shaft in any direction.

Anybody with any ideas as to the cause?
