    Depending on the plug you need from COLD to HOT The BP5HS (cold) to the BP8HS (hot). The gap should be around .017 to .020

    Mines gapped to .031.
    Works 10x better.

    use the biggest gap that works well. I'm running .055

    larger gaps resist fouling better and have an easier time igniting large amounts of fuel

    I run them at .032"

    In short, the biggest gab you can get and still get a spark.
