almost for sure was once a Roadster2. The trials tires give it away (not black widow or enduro.) Also if the frame was originally black, probably 1972 model. and i agree with what guys posted... you can get the parts, but man it's gonna cost... Gas tank, seat/foam, torque converter, jackshaft, clutch cover, rear fender, cables, MOTOR, exhaust, probably sprockets... man it adds up!
