Four stroke engines for bicycles, anyone on this forum got one? At the moment i have a 60cc chinese 2 stroke and it's fine for the moment, but eventually i'd like a 50cc 4 stroke preferably belt drive, i've been searching the net, and have found quite a few, but they are very expensive, can anyone recomend any companies and brand names for engine kits (4 stroke) I believe CMI in china sell both 2 and 4 stroke kits but they wont reply to my emails unfortunately, any help much appreciated.
