Frankencycle - My motorcycle that rose from a grave

Basically I took a Schwinn Jaguar and cut everything behind the seat post. Then, I welded a plate to attach my Predator 212 cc engine, removed the governor, did the math for mph with rpm and diameter of the wheel. 55 MPH, 1 Speed, Auto Transmission, wheelie-popper, BEAST.

I post this because I would like to hear suggestions on how to improve it, and eventually make it street legal.
