the poll is all over the place..... LOL

anyways, i have been using 87 but might switch to the 91 to see how the bike runs on that!!!
if anything, I will use 87 and every couple fill ups will go with the higher one as some suggested.....

I always thought that the higher the octane rating of a petro or gas, the better for the life of your engine (I guess, that's why the higher the octane rating, the more expensive it is.)


I do find better gas mileage with higher octane on my car. Haven't really checked on my bike (i just run super since the ~ dollar extra per fill up is pretty insignificant)

I did find that after installing the sarachus, the bike had a flat/dead spot and hesitated between 4k-6k RPMs. I put super in and it ran better (i'm pretty sure tweaking the air/fuel mixture valve on the carb would've resolved this too)

I run 93 on both my bikes and my car...figured it can't hurt.
like fdoangulo said the premium stuff has more cleaners and additives to make it run better, its usually the first recomendation from a dealer or shop that isnt trying to screw you. you can still run the cheap stuff but a good tank or two every once in a while will clean the crap out.
Periodically running a bottle of fuel cleaner like Seafoam would still do a much better job than the periodic fill up of 'premium fuel'. That is if the particular gas station you go to actually puts a cleaner in their premium.

I have always put in 91 or higher in my bike and have not had any problems with it. I have heard the at higher altitudes you can run a lower octane fuel as well. Any truth in this?

The thinner air combined with less oxygen means less heat from the combustion chamber, allowing a lower octane to be used.

When I was in Colorado last year, I was at a gas station that sold 85 octane.

From a Coloradoan 85 octane is the standard here. I run it all the time and have no probs.

I cannot prove it. But I am working on it.

this poll is def. all over the place.... i figured that it will go one way at some point but way even.... LOL

i guess if the bike runs good on lower fuel then go with that,..... also, if you want to have a faster and better performing bike go with higher - right?

Generally speaking, Octane does not equal performance. Performance engines on the other hand require a higher octane. You may see some increase between ratings, or you may even have a decrease. But unless you actually Dyno your machine you will never knowand if you did dyno it wilth different fuels i doubt you will see much of a difference. Mainly just preference.

Higher octane fuel is harder to ignite, more energy is required to ignite it. The higher the octane rating the lower the total energy output. A high octane rating helps to prevent detonation. High octane is usefull in high compression engines. 500's don't have high compression engines. That's my .02 cents.[:'(]
