got a yz426 that has an oil leak that is driving me nuts. it seems to be coming from around the front sprocket shaft. i have replaced all the parts twice but it still leaks. have replaced seal, o-ring and even the collor but it still leaks. any ideas.

Leaking someplace else, bad bearing for the countershaft allowing the shaft to run out in the seal (off center).
