Hey guys, maybe someone can help me out. I just put in a new top end (and had my jug ported). Got it all buttened up and went to start it up and do a couple of heat/cool cycles, and it went strange on me. When it started it ran a little high in the rev range, and seemed to over rev w/ each blip of the throttle. I shut it down and sthe re-started th bike sounds a little odd and is surging. do you think it has an air leak? Any ideas on potetntial fixes or do I have to bite the bullet and rebuid again? :|
