any one use race gas in their quad, im considering running some in my 700r raptor, but iam mostly stock except for a k&n and the lid off, im just curious how much octane i could run and if it would make any difference, in horsepower at all, i would also like to know where i can get some race gas online and what brand u guys would reccomend thanks

 

Monster, what I gather about fuels is that they are saftey measures. What I mean is the more octane you run the less chance you have of detonating your motor. Higher compression motors or power adders require more octane because there being run harder.

You probably wont notice any difference in hp on your bike by running a higher octane of fuel. But you will notice a difference in your wallet. 110 race fuel runs almost $10 a gallon around here.

Just run what your bike calls for. JMO

Sunoco and Vp are good fuels to run.

 

Just run 93 octane, a stock Raptor doesn't need race fuel.

 

ya just run the high end pump gas. Thats all I run in my yfz, and it is the minimum. The race gas isnt worth the price unless your bike is pumped.

 

just run 93-94 oct. You can accually run 87 and wont notice a difference.

 

I run 114 but im not stock and yes u can tell a difference, sometimes i run alcohol but race fuel is about $4.67

 

Welcome to the forum MONSTERMATT! [img]i/expressions/face-icon-small-smile.gif[/img] I use a mix of 100 octane(1.5 gallons) with 92 octane(3.5 gallons) in all my 2 strokes. My Thumpers run 92 octane with no problems.

 

Try THIS.........

Half way down the page, U4 fuel.......92 octane. GOOD STUFF

 

All you need is 91 with your stock pistion..If you go to high it will hurt you more than help..

I hope your running 13.1 pistion or higher..If not your just pissing in the wind...

 

I've ran U4 in the past. Due to it being oxiginated you will have to up your fuel curve and around here it's about $7.50-$8 a gallon. I don't know about you but that's alot of $$ for a very minimal gain.
