OK, I made a goon mistake. I think I got the pressure washer too close to my seal, but it confuses me because there is a metal cover on the seal and it is very tight against the case. It started leaking and was simply dripping so I could add oil as I rode at the MX track. I got a new seal and put it in but now it leaks like a sieve. I could not get the metal collar off so I simply put the seal on over the collar. The seal is not exactly flush with the case. could this be the problem? Does the sprocket need to be on and tightened to help with the seal of the collar o-ring. I am so bummed because I have this brand new bike and am afraid to ride it now because all the oil will leak out before I get 10 laps in. Any help would be greatly appreciated. By the way, i do not use a pressure washer anymore.
