Re: nitro bike
Go ahead and try it. It won't hurt your engine...it won't give you any power gains either.
If you put straight hobby fuel in your tank...the engine will not run. Try it!...If you mix it with gasoline...it will run, but not better!
You guys need to understand the characteristics of Nitromethane before even thinking about trying it as a fuel. I know I'm annoying...but I do build the engines for a 4-cylinder Top fueler that runs on 90% Nitromethane and 10% Alcohol.
