4 stroke bike

This project came about when my son sent me home with a bike motor kit and asked me to turn it into a motorbike. The motor is a 48cc 4-cycle with centrifugal automatic clutch. A friend gave me an old Phillips 3 speed frame and I had a heavy duty fork in the shop as well as some steel 26" wheels and some extra tires. The motor is fairly smooth and quiet and pulls up hills pretty good, which is fortunate as there was not room enough for pedals to be installed. The gearbox generates some whine and the chain idler will need some improvement but the finished product shows promise as a fun little motor bike.
