    Default Nihilo head compression

    Has anyone run nihilo head on a ported 105 on 97ron fuel? Put above head on mine and with correct squish the bike has too much compression and has detonation. We must use 97ron fuel so race fuel isnít an option

    They are designed for race gas. If you can't run higher octane, then it's no good for you. Call Twisted Development and have them cut a head for you that will work with the fuel you're running.

    Couldn't you just add a thicker base gasket to achieve the same thing? Or would that mess up the port timing?
