It really amazes me how many people don't realize how much hotter an air-cooled engine runs under load at less than full throttle. It's not good for the hydro either, as much less air will be moving over it at less than full throttle. Since you can infinitely vary the speed of the hydro, it's just stupid plowing at anything less than WOT.
