It's a 2003 yamaha raptor 660r limited edition. I just finished rebuilding the motor. It has a 686 big bore kit, a stage 1 hotcam, tusk clutch, kibblewhite black diamond valves, hotrod crank and connecting rod, heavy duty rear axle carrier and bearings, and more. Motor doesn't have 8 hours on it. The bad is it needs a battery and a solenoid.
