A few gas stations around here have 100 octane gas. It's expensive but I wonder if it'll enhance performance. Of my bike.
Anyone try it yet? What did you think?

 

Probably not. High octane fuel doesn't even make a difference on stock motorcycles with high compression engines (sportbikes).

 

I used to run 110 octane race fuel in my bike, but it is a high compression engine and ran better on high octane fuel. Octane is a combustion inhibitor and is only effective on high compression race prepared engines, where pre-igition is a problem. Try the fuel and see, that is the only way you will know for sure. By the way, I am a tech and my wife is an engineer in an oil refinery.

Race gas won't add any hp to your normal engine. If you have higher than std.compression, or an engine with a more advanced ignition timing curve, then you might notice a difference running race fuel. Race fuel only curbs detonation....

 

Race gas is for race engines.

Is yours a race engine?

 

On a stock engine with no perfromance upgrades it wont help much. If you have a stage II and are tweeked to the limit on ingition advance then higher octane will help elininate the pinging. but you wont see much improvement for the money spent.

I run it ocasionally in my bike and you canreally tell the difference, butI have a 120 with high compression and always run premium at best.

 

I get it at the race track for the car we run (110 octane), I tried it in my bike last year and really didn't notice any change at al in performance.

 

Won't you fry your engine with that too often?

 

running 100 in my bike made it run like S**T, I have a carbed 05, with a Hi comp 95 kit,

and to put it in a nut shell, the high oct. fuel makes you bike think your running richer that it was running before, I would have had to lean the jetting out to make it run better.

Im unsure of what would happen on a FI bike.

 

As stated above octane is the measurment of a gasolines resistance to burn. The higher the number the harder is is to burn, so if you run high octane gas in a motor that doesnt need it (low compression and not alot of timing) then you are actually making your motor work harder and are getting less gas milage then you would with a lower octane.
