    What Octane is Best?

    What octane is everyone using on their ported skis? I have been using 93, but becoming harder to find. Will I run into problems with 91?

    If you search around a bit you will find some of the guys using 87 octane with great results on their lower compression motors.

    Hard to say in your case because you didn't list your mods.

    Any octane boost work well? I can only get 91 octane. I have heard that the octane boost isn't as great as getting the numbers from the gas?

    Octane booster is worthless, use the 91 and you'll be fine.
