    my brother says running a bike lean will give you more power..."more heat, more power" was his mantra. I know my bike felt like it had more power after I installed an Xied on it, so I feel richening up the mixture will give you more power..whose right??

    In my opinion, it will only work that way if you're already running too rich.
    How would you get more power by removing the fuel?? An engine runs hot when
    it's running lean.
    Add more air,
    add more fuel,
    get it out the exhaust.

    Start over. :)

    Richer..for Power.
    Richer...for Safety

    You can take more chances with running lean when watercooled.

    Actually Stoichiometric is 14.7 to 1 which is lean.

    You actually want to run a mixture of under 14.7
    Example: narrow band o2 sensors try to maintain the engine @ Stoichiometric or 1 lambda.
