I have overheating problem with my 06 yz450f when I go into the woods or go on the low speeds . My body has a 2003 yz250 and has no any problem with overheating even if hi gets stack and has hard time to get out of the woods. Is something wrong with my bike or that`s normal becouse of not enough air flow at the low speeds. I have even replaced colant for Ice Cool antifreeze. After that runs little bit better but finally overheats in the woods. Anybody can give me some ideas ?
