    Octane mixing?

    With 42cc domes, novis and factory pipes would the octane need to be raised? No porting and no spacers.

    Running Sunoco 260? You could lower it.
    Can't read between the lines or read your mind
    from so far away.......y...................y.................. ...ay
    The mixing issue is, do you know what you want? from what
    you are useing? Going up or going down? Ethanol Eliminator?
    Are you loking for a blue mixture or orange/white?
    Methane or toluelene? Price you want to pay per PPM?

    Yes... To be safe you will need atleast 100 octane..

    If you know where you want to be octane wize, invest in a portable
    handheld meter, and you will know what you have, then raise by
    the hit and miss method with your booster, be it from napa, methane
    or (I use) Toluene. Thats how you get it, too much and BOOM!! Race
    fuels can be bought outright locally.

    I wasn't sure if I needed 100+ or not. Hmmm.....maybe I'll take the heads off and leave the rest, would I still need to mix?

    No! The problem with raising compression with pipes is that the pipes where intended (91 octane) to run around 125 PSI so anything higher will cause detonation without higher octane.
