There is a quick fix. Zipty Racing sells a waterless coolant, yes that means it is a full synthetic that will not start boiling until 375 degrees. It aids in the cooling as well as keeping the boil over point down. They supply it to factory offroad suzuki, factory kawasaki, factory KTM, and other teams. This is the secret to keeping the bikes cool. Call up nathan woods, kurt casseli, barry hawk, ryan hughes and ask them what they run, they will tell you. It is called XF+. It is the answer.
