I know a friend that can get me 110 octane "Av-Gas" for alot cheaper than $3 a gallon unleaded, I guess it is the fuel that you buy at the airport. I know that it is blue and already has a oily base to it....Can I run it in my dirtbike(RM250-265kit) and just add like 50:1 2-stroke oil? This way I could buy a stock head (up the compression) and wouldnt have to worry about ping...
