I posted a question on "what is the best four stroke engine" thread. It since has turned into a heated argument. My question is this: I bought a 49cc 5G 4 stroke from BB with the belt tran. has anyone in this support group run one of these? does anyone have one? What are my concerns with this engine? I'm putting it on an 85 Schwinn & 26" cruiser, (heavy in metal). Will this engine be enough to move the bike? I already bought it and in a week I would find out if it was a good choice. I had a few problems with the 2 stroke engines and would really apretiate a somewhat reliable engine. I'm addicted to this now!
