Have you had problems before switching? I never had problems on the the track or on wideopen trails. I just had this problem on the evart trail. I couldn't go fast enough to keep the radiator cool. :ride:
Seems like I did have a little overheating (overflow more likely) but switched to the blue juice right away so not much testing without it. Afterwards, had zero overheating issues including 99 degree days trials riding on new Tomahawk trail sections (1st gear, clutch slipping stuff).
