i have a 86 Honda 250R that i bought off of a guy that raced XC and it's setup to run off race gas right now and i am going to race XC this season and i wanted to know what all i may have to do to make it run on 94 octane pump gas. I'm pretty sure that all i have to do is get a new cylinder head that is setup to run on pump gas. Or do i have to get a whole new cylinder too. the reason is because i don't have alot of money for race gas cause i'm only 16, but with gas prices keep rising i just decide to leave it the way it is. I would pay 1.83 a gallon for 94 octane here in PA, but i would only be paying 2.30 a gallon for airplane gas which is about the same thing as race gas. the airplane gas is 110 octane. So i'm not paying too much difference between the prices and i heard race gas only makes it run cooler not better, is this true.
Thanks

 

dont be a fool and run aviation gas. its not the same thing!!! its made for real high aviation not where you will be riding. Ask your local dealership or call up Klotz. they would just laugh at you if you wanted to use aviation fuel. sorry but thats my 2cents

 

How much are the parts? How much do you ride? If the parts are say, $100, and the difference in price of gas is $0.50 per gallon, it would take 200 gallons to pay off the part change. At 20 mpg, that's 4000 miles. I would figure out how long it would take to pay back the parts before making the switch. Rarely does paying to use cheaper (or less) gas make economic sense.

i been running airplane fuel in my 250R and it makes it run just as good as the race gas that was in it when i got it. i don't know how hard it is to get that kinda gas up in NY, but here in PA it's harder than hell to get it for a cheap price. the only dealership around my place is the damn Yamaha shop and i don't go there very often, the only time i went there was to buy Bel Ray Gear Saver oil and muffler packing for the Suzuki. i called a parts shop up and they told me that i could get Klotz 110 guess what the price was. 40.00 for 5 gallon, geez i'm not rich. i think i'll stay with the airplane fuel since it's only 2.30 a gallon and it makes the quad run just as good.
