Bruce, I have an idea to help with the cooling issues. I remembered that the 300 introduced a radiator fan shroud to help with cooling the bigger displacement. Granted that the new shrould does effectively pull more air through a bigger surface area and direct it down away from the head and cylinders, why not make a shroud that covers the entire radiator to maximize the efficiency of the fan and radiator? They do it for cars and trucks, why not apply to our bikes?
