I have a regular motorized bicycle with a china motor, I am now putting together a Schwinn copper with a pit bike motor, I am using a 50cc motor to stay legal on the street, it says 50cc on the motor, but it will have a 100cc upgrade kit with a racing head and max cam, large carb it should have 4x the horsepower then stock. I like this setup because of availability of parts and the 4 speed trans.
There will be some mods to the bike, but I am trying to keep them to a medium. I also have to keep the peddles on the bike to keep it legal as well. Otherwise it would have to be lic.

I am 75 and getting younger all the time, Have to keep my mind busy and my hands working.

Sounds cool. How are you going to mount the engine? There aren't any bottom plate mounts, only the top threaded holes meant for pit bikes.
