Not for the frame your thinking of jimmy, those antig frames used things like Yamaha or suzuki 2 strokers they will fit right in and youll get more parts more often, even a tweeked Dt 250 motor would be fine, you really want it to haul get a 360, 500 or somthing. UNles you want to go down the JAP, JAwa road and go kinda period, youd have more fun and less headache dragging home a cheap Rice burner from the wreckers that you can just feed parts too, thats if your going to race the thing. Race or restore your at the cross roads my friend.
