hi everyone im 16 and i live in paradise. i orded a engine and assembled it last week. so far so good. no complaints. apparently i am the only one on the whole island with a motorized bicycle and everyone wants one, so that gives me an idea to start my own business and sell these bikes and engines. i can only lisense the 50cc engines. are the 50cc and 66cc engines the same size? i want to know if i can fit a 66cc kit(block and piston) on the 50cc engine. also im setting up a sick bike, waiting on performance parts. gonna max this bike right out. carb, filter, pipe, shifter kit, shaved blockhead, open up the ports, and maybe a nos kit. dose the nos kit work?
anyway thanks for the help.
