I did a search for my question but since the only thing i found was 2 to 4 years old, i thought id ask it again( probably with the same results, but hey).. I have a stock XB12Ss. I just noticed that a new gas station that was build down the road has a seperate pump off to the side for TORCO 110 race gas.. I never did look to see if it was leaded or not, but i guess i just wanted to see if anyone has tried 110 on a stock bike with any results! Im sure its just a waste of money though.....just wanted some updated thoughts about this!!! | ||

What I understand is unless you have a ground-pounding, high-compression motor, you are just pissing it down your leg. | ||

if your bike isn't pinging badly it's a waste. | ||

What I understand is unless you have a ground-pounding, high-compression motor, you are just pissing it down your leg. That is correct right there. 110, octane, will burn really slow compared say, 93. Run the lowest octane you can without pinging. You wontgain any power otherwise. Only difference I can suggest, is, sometime you can find oxygenated 100...THAT will make more power, but it burns hot... Chase} | ||

I used to run 110LL in my Piper. . . that count? | ||

There is something else to consider... Besides octane ratings, race fuels sometimes burn differently. Often faster. If the ONLY change was octane and your motor had no appetite for anything over 91, you may actually get a decrease in mileage or power. (un?)Fortunately, race gas typically isn't exactly apples to apples when compared to street swill. -Saro | ||

ok, cool. so i guess not much has changed in the last 2-4 years with new motors and higher octane fuel?? I guess it wouldnt hurt to try it at least once, to see the differance!! thanks | ||

You need to check if it is leaded or not, other wise new o2 sensor lead fowls these devices .... | ||

Louie at L&L Motorsports (the dyno guy in almost every RRW tech article) - told me NOT to use more than 100 octane in my racebike since I'm not running high enough compression (at 10.5 to 1) - and could probably even LOSE power. If you are pinging and you have a clean engine (no carbon/hot-spots) and are running high compression, then you MIGHT benefit from higher octane. Save your money - I get the same HP using Chevron 92 octane unleaded pump gas as VP100 leaded. Did get barely 1.5 more HP with Ulitmate4 - but wasn't willing to pay nearly $8 per gallon. | ||

If you intend to try it keep a spare o2 sensor on hand. with leaded fuel the foul in seconds. Even running 11.43:1 compression my bike runs on 93 octane. What compression ratio are you running? | ||

Now this is why I love a carbuerated bike. You can try all this fun stuff, no problem. I know a few guys that club race and they run 50/50 pump& race gas and I haven't heard any complants about O2 sensors.But It will be an issue sooner or later...........Charlie | ||

after thought here,  Air craft typicaly run LL100 ( low lead 100 octain, the sensor is not the only issue you may wind up with, under student usage, light planes have issues with plugs getting fouled in a few hours of operation, those engines are much like ours low rpm push rod long stroke, ( they have 2 plugs per cylinder ) with extensive use of avgas you may wind up having to pull the heads to clean them and the pistons up. The airplanes can control the mixture and lean it out which helps keep the engines clean to a degree, but depending on how the training aircraft are operated they could be pulling jugs at 100 hours thats not too many tanks of gas I dont think that I would pay the $6.00 or more a gallon for fuel that serves no benifit.. if you want more power from your fuel try nitro at 20% you could get horrendous power........................................................................... ................................................................................ ................................................................................ ................................... for a few seconds any way. | ||

na i really dont need more power!! just wandering what it would do to my motor if i tried it once!! i did check it, it is unleaded. Its also $4.29 a gallon. not TOO bad really, since 87 is $3.00 right now! | ||

 na i really dont need more power!! just wandering what it would do to my motor if i tried it once!! i did check it, it is unleaded. What is unleaded Not AVGAS .. see above  } | ||
| Americanmadexb |
no.... the TORCO fuel by my house is unleaded! see above | ||
| Oldog |
Sorry! Started to try it once my self for pinging How that work? not too good!  | ||

your (stock ) buell has barely 10 to one compression, cranking pressure of around 150 PSI, the octane requirements are about like your average toyota camry. race gas is a complete waste of time. |
