I just baught a JE 13.8:1 piston for my KFX. Can I run it with a 50/50 mix of 91 and race gas. Im wanting to know cuz I have a friend that is telling me that I will have to run straight race gas if I put it in my KFX. I don't belive him but I thought I would ask cuz I know I will have to start running a mix of race gas.
