I have a 2000 400ex, I bought it with a high comp piston, stage 2 hot cams, aftermarket header, dg exhaust and a couple other things, I have been thinking about running race fuel to try to get little better pover maybe a little cooler running but mainly to be honest the smell lol. My question is would it be ok to run race fuel with this setup and if I do a 440 big bore will it still be ok to run?
