you can find 49cc 2 strokes on skateboards, they have auto clutch, throttle and nice exhaust. i get them on craigs list for 30-50 bucks. they come on scooters and gopeds.

if you are looking for a all black motor only -- you will be very limited

looking for some true quality maybe ?? Honda or Robin or Mit -- made in Japan

ride the motor bike thing

"Zoom" sells a black kit and it's just over $100. It's in BC and will give you a good bang for your buck.
