I figured I'd check in here as well as the KX 2-stroke forum as I know there are several racers who converted from KX500's to XR650R's for racing. Anyway, I have a friend that just picked up a KX 500 for desert racing and wanted to set it up properly. Does anyone have experience with setting up this bike (tips, tricks, bolt-ons specific to the bike, etc) that they could empart? Any help is greatly appreciated. Thanks!
