it could be the side case if you dont have a strong case saver. look behind the chain cover. sometimes its repairable.

it happens alot if you dont have an aftermarket billet aluminum case saver.

I would look very closely at the side case. I had a chain come off recently on a 250r and made a very small hole in the case. I was able to repair with JB Weld. My buddy had a chain come off on his YFZ and made a much larger crack that required a new side case. His was spewing oil everywhere. If not much oil is leaking, maybe the hole is small enough that JB Weld will do the trick.
