I have for sale an '83 XR500 RD motor. It is only missing the stator and stator cover. It has a freshly bored cylinder, with a new in the box, 92.5mm Wiseco, 10.25:1 compression piston. I purchased this motor from a wrecker around about 1985, as a spare for my '84 XR500. I never got to use it and it has been stored in a cupboard in my shed ever since. $600. Located in Townsville, but I can bring it with me to the Conondale vinduro sprint or to CD10.
