Thanx, I think I found the prob. My exhaust wasnt buttoned up to the manifold very tight Im pretty sure it was knocking there. I still need to tighten them up and see if it stops. Thanx again for your help.
Ok did that, there looks to b four places (all screws) that appear to leak oil. do I just need to get a new gasket kit for the lower end of the motor or just keep an eye on it and keep runnin wide open?
I just got a 04 blaster and love it, but oil is leaking from the bottom of the motor. It looks like from the screw holes on the crankcase. I also have oil coming out where the exhaust blots up to the moter? help please
