That depends on the specific gravity of the fuel, not the octane.
On pump gas the advantage of higher octane is that it lights off at a higher temperature, which helps prevent detonation.

Do you mean 93 octane, with ethanol?
When the gas pump had the big sign on it that said ETHYL, that was a good thing...
I`m almost 66, and that was before my time...

yup, I can't find 93 pure near me, damn nebraskan's love their corn. I do have a pump nearby that has 91 pure and I run that anytime possible. I try to avoid ethanol at all cost in the bike and try to stay 91 or higher. Back when I was racing, I kept a 55gal drum of VP motorsport 103 in the garage but that **** gets expensive fast.

I just got 2 gallons of race 110 went for short ride then got 2 gallons of 91 pure gas. After that it was running real good and the right pipe is looking clean. smells so good. Im running lean do to SE pipe with no tuner yet. still looks lean but no more specs. Also ajusted TPS and a bit of MM oil to go with the race gas. Going to try just the pure gas for a while but even that is $1.50 more than regular. Race gas is $7.19 here so won"t be getting alot of that but want to get a bit more before I get a tuner.
