chetgoff Posted February 16, 2010 Report Posted February 16, 2010 Well just curious I got this banshee that has been running on Av gas and I putting a new top end on it and want to start running race gas. I read a forum that says you have to rejet for race gas has anyone experienced this Quote
dave5.0 Posted February 17, 2010 Report Posted February 17, 2010 I've been running avgas for a long time. It's usually cheaper to run than race gas. Alot of people would not recommend running avgas though. But I've had good luck with it. Oil doesn't seem to seperate from it for a long time. Only reason I would think you would have to rejet would be if you changed the mix ratio or made some changes to the motor. Do you have enough compression that you even need to run that type of gas? If not it might be a waste of money for you. Quote
GrMeyer Posted February 17, 2010 Report Posted February 17, 2010 I run a 75-25 mix of AvGas with 91 pump. I have been running it for about two years now with some hard riding on it. Just changed out my domes and everything still looks good. I also run it straight in my built raptors. Just re did my rings on my 660 and everything was very clean. I think that the LL is what gets everyone. Meaning Low Lead. Plus it is about half the price of race gas here in Phoenix. Quote

dave5.0 Posted February 17, 2010 Report Posted February 17, 2010 Dave where do you buy your avgas at? Airport in Quincy will not sell it over the counter. The one in Taylorville will. I've been getting it there for years now. Long as you aren't trying to put it in a car right there they don't seem to care much. Quote
chetgoff Posted February 17, 2010 Author Report Posted February 17, 2010 thanks for the replies guys I was just starting to second guess my self after reading the article and wondering if it will keep the bike cool enough. since the additives in it are for running at higher altitudes. the guy says he mixes it with 4 gallons of Av fuel to a bottle of oil that is for 5 gallons not sure what ratio that is but it seems to run ok. this is my first banshee and 2 stroke at that Quote

AVGAS doesn't need more oil to run so run whatever is recommended as far as a ratio goes. Different oils can have different suggested mixing ratios. The consensus seems to be that if you have over 155PSI compression, you need more octane than premium has. I have 165PSI and I run a 50/50 mix of 100LL AVGAS and premium and mix 36/1 Yamalube 2r. No issues, problems, or disappointments after 3 hard seasons at Glamis. I'm a AVGAS happy guy at less than half the price of race fuel. Quote
GrMeyer Posted February 17, 2010 Report Posted February 17, 2010 You got to love the smell from the av gas being ran in the bike. I know i love it when I get behind my brothers bike that runs it. Might not be good for brain. But hey, you only live once! Quote
TwistedSheeRida Posted February 18, 2010 Report Posted February 18, 2010 i ran 1 gallon of av gas to 4 gallons of 93 premium at the beginning of last year. kinda ran hot. They sell MO Gas at the airport which is 93 premium without the ethenol additives. Been running great off that stuff ands its only like 1.00 more a gallon then 93 pump. Quote
GrMeyer Posted February 18, 2010 Report Posted February 18, 2010 Damn. I wish I could buy 93. The only thing I can get at pump is 91. Yeah that's one thing people do need to watch out for with 100LL is that it does tend to run a little hotter because of the shit they put in there for high alts. Quote
NVRBanshee Posted February 18, 2010 Report Posted February 18, 2010 our airport has 104LL i ran it in mine for years till i went to oxygenated fuel Quote
