When I rode Dirt bikes I thought liguid cooled motors were just more weight and more to go wrong and after all the bikes were light and alway went fast so lots of free air was flowing through the fins of the engine.But when I seen how the ATV sport worked I saw heavy quads with motors no larger than my light dirt bikes working harder but getting no speed to get the air through the motor that is buried in a large frame where you wounder how its gets air flow at all.The riding is different with quads where the quad is working hard in rough terrain but the quad is only doing a few MPH at best so I think the liguid is the way to go in this sport.

 

I'm sure your right Tim. Does anybody make a liquid cooling system I can retrofit onto my air cooled TrailBlazer? I mean, I have never overheated it but if Tim thinks liquid would be better, then maybe I should check into it.
Just kidding Tim, your ok in my book.
