Blue Duece Posted December 12, 2003 Report Posted December 12, 2003 have you guys ran aviation fuel in ur shees. i thought it would make my shee run better because of the high octane but it made it run really crappy. do any of you know why??? i know the place i get mine has 110 and 120 for bikes and a differnt pump for planes i think there might be a diff......

chase73 Posted December 12, 2003 Report Posted December 12, 2003 I am pretty sure avaition fuel is leaded . Quote
Blue Duece Posted December 12, 2003 Report Posted December 12, 2003 I am pretty sure avaition fuel is leaded . will that screw up your bike chase? Quote
96shee84z28 Posted December 12, 2003 Author Report Posted December 12, 2003 should i run aviation fuel when i get my coolhead with 20cc domes? and is there a big diff. between race fuel and aviation fuel?? Quote
gumby Posted December 12, 2003 Report Posted December 12, 2003 aiation fuel is a higher octane rating but i dont think a shee has enough umph to burn it and its designed more to burn at high altitudes hence aviation fuel. i think its kinda like putting alchol in a regular gas motor it just dont run right Quote
tr6shee Posted December 12, 2003 Report Posted December 12, 2003 Hey I run av gas in my o3 shee, I have 20cc domes bored out w wiseco pistons tr6 pipes 2:1 air filter, advanced timing and boysen reeds ,It burns a little hot but Ive never had a problem, whatever you do dont run pumpgas With 20cc domes!

MRMOONEY Posted December 12, 2003 Report Posted December 12, 2003 i run av gas in my bike and have for about 2 years, its alot alot cheaper then race gas, i have never had a prob with it. My builder suggested me to run it. just my 2 cents. Quote
banshee370 Posted December 12, 2003 Report Posted December 12, 2003 Yes 100LL (av gas) is leaded. NO it wont hurt your motor! I too have been running it for years. NO problems AT ALL! Tip: 100LL burns differently than pump gas, Race gas burns differently than pump gas, 100LL burns differently than race gas, ect ect ect ect........... 100LL will actually burn COOLER then pump & race gas. JETTING changes MAY be necessary when changing ANY fuel. This topic is just like a ford vs chevy debate. Run what YOU feel comfortable with. On "MY" bike I am able to run MORE timing advance than if I was running race fuel. Does this mean race fuel is bad? No. Does this mean that 100LL is the best? NO. ALWAYS check your jetting when making any changes. Quote
MRMOONEY Posted December 12, 2003 Report Posted December 12, 2003 very very well put, i love av gas, its cheap and it works when you have alot of compression, i also laugh when people say but its for high alitudes, so alky is for funny cars does that mean we can't run it um no... Quote
boonman Posted December 12, 2003 Report Posted December 12, 2003 I have witnessed aviation fuel make a motor run hotter. I don't and will not run it in anything I own. Unless I get a plane. But I highly doubt that.. Quote
94BansheeRider Posted December 12, 2003 Report Posted December 12, 2003 Even though AV gas is cheaper, I have been told not to run it because there are additives in the fuel to keep it from freezing at high altitudes. Kinda like antifreeze. I will not run AV gas in my shee. Besides, I like the way the race fuel smells Quote
RUNMYTA Posted December 12, 2003 Report Posted December 12, 2003 This question has been beat to death. If you do a search you would see that. AVGAS/100ll WILL NOT HURT YOUR ENGINE!!!! AVGAS/100ll WILL MAKE YOUR ENGINE RUN COOLER!!!! The small amount of lead that is in AVGAS actually helps reduce detonation. AVGAS/100ll has a higher oxygen content than Race/pump fuel. So when using AVGAS you "typically" need to jet one size larger on the main! (If you are lean you will run hotter ) You only need higher octane fuel for higher compression engines. Just because you have pipes, intake mods, or any other bolt ons does not require AVGAS/Racefuel!!! Only when you raise the compression (My prefernce is 180lbs or higher) will you need to run high octane fuel. Mike Quote
2banshees Posted December 13, 2003 Report Posted December 13, 2003 i run it but its supposed to be a secret. runs 100% better than 91 octane. ive had no problems. tore the bike down for rings and the topend was clean as a whistle. i run av gas with amsoil works 4 me. but do whatever. its your bike.

azsandrat Posted December 13, 2003 Report Posted December 13, 2003 I've been running 100LL for a few years and have had no problems at all. If you run hot on AV its too lean as stated before. Ihave 3 Banshees,2LT-80,Lt-50 and a Odessey and they all burn it at 32:1 with KLOTZ oil. NO PROBLEMS AT ALL. The banshee motors are all strokers and big bores. So if This helps you in your decision, I have alot of money in these toys!!!! Good luck with the decision. Quote
