I really need to find out because I never thought of it before. Is there anyone that could help me figure out how to make a possible 1 rotor for a high-output hill-climbing dirk bike? The frame I will custom make around the engine, its just the rotary would do so well, mabye even turbo??! Please somebody help me figure this out?

 

not a bad idea, but the cr500's are so competetive. There are some guys pulling 110+hp our of the kx 500's too, a 1 rotor could make that, but it would be way heavier, cr500 engines way 50 lbs.

 

Well heres the thing though, they have an unlimited class that they run pretty much anything including 4 cylinder and snowmobile engines. What I would like to have is the rotary motorcyle engine they had, or even the snowmobile they once made...

 

you could get what.. 150 hp out of a single rotor,
i know atkins sells e-shaft for 1 rotors

 

I completely forgot the fuel that those cr500's and **** use, 100% nitro at $35 dollars a gallon. I was sorta hoping to make that difference up. I would however prolly would be better off with some kind of turbo, or mabye supercharger. I even might have to go with a old rotary motorcycle engine too, and they were air cooled. So I need to start looking..

 

if you are talking about the RE-5, I think it is water cooled.

 

I still think the ones with the street bike engines will have a large advantage because of weight.
