Nitro mix for Banshee?
(Click here to view the original thread with full colors/images)

I was out riding at Haspin acres last weekend when I ran out of fuel. A guy parked next to me was loading up and had about 3 gallons left so I asked if I could buy some. Dude wouldnt take my money and let me have the rest of his fuel. He said it was a nitro mix and should make my shee run great. I was very sketchy at first but WOW it made a world of difference. My shee has full toomey t-5's, 4 mil stroker, and 38mm carbs. It seemed to love the nitro mixed in....Thing is I have no idea what to mix it at or a good oil to it with.....or where to even buy it....will the RC car stuff work? Anyone out there that runs it I would love to hear from you

I'm sorry but that is just stupid, im sorry but you were kinda dumb for taking it and good thing he didnt take your money cuz it will probably cost you some, nitro is a low octane rated fuel so it fires easily under low compression (rc cars) and it has a good lubrication chemical in it, which under the higher compression and heat of the banshee well burn it up within a few hours, which is why your bike ran hard, because the stuff was low octane rated and fired too easily (detonation) Nitro is a complete different kind of fuel and should NEVER be ran in a gasoline powered engine, you went way lean when running the nitro mix which is another reason why it ran better, the nitro doesnt flow very good especially when its cold, it gets lumpy, But also this came to mind, what if he was just using high octane and hes not to bright and called it nitro mix LOL, either way do a compression test and get smaller carbs, 38 is killing tons of HP , 38s would be a good size for a Cheetah Cub motor on alky pushing 120 hp not normal 4mil bike

you can run nitro, but you have to jet it rich. the big 500cc 2 strokes at Devil's Staircase hillclimb run nitro, and their bikes are jetted pretty fat and they smoke like crazy until they take off. also if your bike still has some nitro left in the tank, start it and stand by the exhaust, if it makes your eyes burn then it is truly nitro

Sorry 400exrider989 but your the one who is "kinnda dumb"

I know it was nitro by the smell and not just high octane fuel. The guy I got it from had 3 Banshees on a car trailer and was probably a good 50 years old. Im running 38mm carbs because I bought the Banshee for 800 bucks. I decided not to park it just because the 38mm carbs were killing tons of horsepower. And I decided not to buy a cub motor just because I have 38mm carbs.

Its amazing how quickly people are to call you dumb. If you read the topic it ends in a ? You shouldnt expect the person to know what they are talking about. If I was not ignorant to running nitro I would not be asking a question. I would start a thread, everything you need to know about nitro. Why even look at a thread and then call someone stupid, talk **** about how their bike is tunned, and not even talk about the question that is being asked. Mommy and daddy didnt show little johhny enough attention so he has to log on and flame people in a digital chat box. So who is kinda dumb here? The guy who doesnt know about nitro. Or the guy who cannot read for comprehension.

im not sure on where to buy nitro, but i know the R/C car fuel is $20 a gallon or so, and they only use a 10, 20, or 30% nitro mix with castor oil i believe. i think klotz sells a oil that mixes with nitro. and watch the nitro because when i had the R/C cars, the manufacturers told you to spray WD40 in the motor because the nitro contained alcohol which attracted moisture and could lead to corrosion. every time i run out of gas at Haspin, its always cheap stuff or 2 stroke that i find
