I've done two builds now. My first build is working great. The second build is working well, but it has a problem that has developed recently that I don't understand. Off the throttle, everything is great. It pedals smoothly and coasts without any of the problems that happen when the engine is engaged. Once the engine is engaged, it introduces what I can only describe as a "lurch". It's as if there is one spot in the chain that is putting extra load on the engine and it causes the bike to accelerate and the decelerate over and over while on the throttle. The bike is not unridable, but it's definitely very very noticeable. The chain is nice and tight, but not too tight with about a 1/4 to 1/2 inch of "wiggle" on the top. I checked that the chain tensioner is not guiding the chain off kilter. I have a "mega motor" 2 cycle kit mounted on a beach cruiser. Any help would be appreciated.
