My WR over heats frequently. I go through an 80 mile desert race my overflow reservoir will be at the correct level. After the race the reservoir will be empty and the radiator will be 1/4 low. I understand if the terrain is technical and the bike isn't moving fast enough to cool it but it over heats too easily. My other friends with WR's don't have the problem i do. I have only done the grey wire, baffle out, and air box mods. Everything else is stock. Any help appreciated! Can this have anything to do with jetting?
