I am selling a Yamaha KT100 built by Kevin Williams last winter. He put all new bearings seals, honed the cylinder, and put in new piston and ring. I did not run this entire season. the motor still has a few good weekends on it. It also has a HDC5 clutch on it with only an hour on it. comes with air box carb can and motor mount.
I also have the following spare parts:
Old style crank case-$20
Old style Cylinder-$20
