I was thinking tiny race car. Those motors ran hot in the bikes. Your asking it to move a good bit more weight sooooo.

I see more air being moved up over the hood then thru the radiator behind the headlight bucket area.

You might look at some louvers or a scoop in the hood to help draw more air thru and could look at adding another radiator behind the motor. If there ever was an oil cooler on those motors do anything you can to increase it. I have seen a minibuggy with a cbr1000 and he had external oil tank. Cooling the oil would be easy and a big benefit. Just dont push it hard if you ever have to start it when its cold outside till it warms up.

Does it get as hot if you run with the hood off? Just for testing/practice. I doubt they let you race with it off.
