C12 mixed 50/50 with premium if you just want a good all around fuel that isnt crazy expensive, got with either u4.4 or MRX01 if money isnt a problem. mixing the c12 with premium helps keep the lead from pitting the ports and cruding up the valves

I run straight c-12 in everyone of my quads and I never have a fuel problem.
The only time I had trouble is when I had run oxygenated fuel, I don't like it, to much work to clean the fuel system out and get rid of the build up afterwards. I heard that the newer ones don't do that.

not sure about where you r from but in the midwest they have ethanol in the pump fuel and that makes for garbage race fuel and would ruin rae fuel if mixed
.02$

was hoping c12 was ok i will get some thanks

i use a fuel stabilizer in all the pump fuel that i use that eliminates the effects and breaks the enzymes of the ethanol

for practice I run sonocco 110 from a local gas station in Pinckneyville, IL. but for racing we use VP113 or VP U4.4. you will have to got to a slightly smaller just to run any oxygenated fuel.

Powermist has fuel like their UL104+ that is unleaded, and oxygenated with tetraethel ether that doesn't create deposits in carbs or valves and pistons!!!
