Im Going To Drop A 125 Engine In My 50'z But All The Engines That Are Coming Up Dont Come With Carb, Pipe, Or Wheels, So Will My Rear One Fit? Will Only Need, Pipe, Carb. Wiring Loom And Mounts Then Haha! Thanks Josh.
if its an old shape engine the wheel fits, if its new shape you need a 125 wheel (or sr wheel or even a drum runner wheel) new shape has a nut on the side of the tranny cover. also you mod the 50 mount to fit the 125 engine so you need loom/rectifier/cdi/coil and your away
