Brand new-in-box engine for mini-bike, bicycle, quad, etc. Comes complete with carburetor, a new spare carburetor, air cleaner, throttle control handle and cable, handlebar grips, primary reduction ratio mechanism (chain) and centrifugal clutch. Street legal without requiring a drivers' license! I decided to go w/electric motor instead. It will make a fun 'toy' for someone! Price firm. Thanks.
