I've gone back and forth between the 79cc, 212cc, a huasheng, and even a Briggs 3hp engine. I have a 212cc predator, but after some discussion with most of the members on this forum it would be rather difficult for a 15 year old (me) to dream of getting such a homebuilt motorcycle legal. For reliable transportation and relatively low cost, it's not worth it st the moment. Plan is, use the 79cc, put a 33cc sticker on it, and call it a motor assisted scooter. They are legal in Oregon. Add lights and don't be a retard on the road. I will use a mountain bike, upgrade the wheels, front disc brake, jackshaft disc brake, gear reduction jackshaft plate from GTC, and various jackshaft parts I have. Trying to go for a 11:1 ratio if that will work, I hardly weigh 130lbs. Governor will be removed. Homemade exhaust, new air filter, drilled jet. Im undecided on the chain size, but I have 6ft of #41 so I will probably use that. #35 chain for the jackshaft, maxtorque clutch (I already own most of the jackshaft pieces) Budget $900. The cost will likely be less if I'm thrifty.
