Hi all, names Rick and right now im working on 3 builds. 2 have 4 stroke huasheng engines and the other is a 2 stroke. The two stroke is on a 26" schwinn beach bike and one huasheng is on a 32" genesis bike with dax friction on the rear. The other huasheng is a frame mount grubee 4g kit fron gasbike.net and its goin into a iron horse mountain bike from wally. Im thinking of using top hat sprocket adapter on that bike. If anyone has any experience with that sprocket adapter, let me know what you think. None of the bikes are ready but the 2 stroke is close. i will post some pics in the upcoming weeks as i progress more. Thanks for providing such a great place to get info.
