[QUOTE="Jasle, post: 758341, member: 26675"] The motor is pretty much the same thing. The drive shaft on the QT is longer, the pipe is different but the pw pipe will fit. The biggest problem is the right hand side swingarm. The QT does not have one. You have to make a zig zag bracket to hold the swingarm on the right side. For the cost I'd suggest just replacing the crank seals and either boring to an overbore or getting a new cylinder. Cylinders are in the $120 range and you could have fun and use a yamaha YT 60 piston and overbore your cylinder to get a 60cc pw50. The gearing from the rear of the QT is better for takeoff but the shaft going through the center of the pinion gear is too short for the pw50 so you need to press it out and use the pw50 one.
