I think also the added benifit with a cooler running bike is less parts, not saying the fan weighs to much but it chews up some amps from the battery and stator, most water called toys dont have fans, and even on 2 strokes they went with bigger watercooled heads and domes, I like the ideal of the new water pump vs an aftermarket radiator like to hear with the guys with the ESR gauges whats the temp drop.
