Racing Fuel on a new JE piston
I am currently getting a new 11:1 JE piston installed on my Raptor with a Stage 2 Hot Cam and 686 kit. It is also getting ported and polished while it is in the shop. I was going to go with the 12.5:1 piston but the mechanic told me that i would always have to run race fuel. I dont have a problem running race fuel, especially in the dunes, but when i ride in the mountains where there is no need for speed, it would be a waste of money to run race fuel. He told me that i wouldnt have to run race fuel on the 11:1, but i heard about some problems with the JE piston when using the wrong fuel type. Would i get into some problems if i ran race fuel at the dunes and Premium(92 octane) when casual riding in the mountains/woods?

I would personally buy some cheapy octane booster to be on the safe side.

Just my opinon but I wouldn't use the 11/1JE on pump gas, although you might get away with it from easy riding.

Thanks Ward, you're right. I would run racing fuel as well just to be safe.
What octane for an 11:1? I use P C12 on our 12:1 bikes?107 octane

A 12/1 your about right at 107 with a stage 2. IMHO anyway.
Let Trinity do some chamber mods, use a 685 Web cam, and you could probably run an 11/1 JE piston on 87 octane.[img]i/expressions/face-icon-small-shocked.gif[/img][img]i/expressions/face-icon-small-wink.gif[/img] LOL
