    The plugs are most likely oily from the oil in the gas on the break in. Changing the plugs will help, but save your money and buy 87 octane. You don't need 93 unless you have higher compression.

    If you go months in between riding, you could run 93 octane just to insure the octane will still be 87 when you do ride, but other than that you don't need it with stock compression.

    I have a 1300 2004 stocker and I have tried 93 87 91 87 gives me the best profomance. I have had some tuners tell me that with stock comprestion the motor runs too cool with higher octane?

    I have ran 101 in my BB (mixed 93 and 104 according to the chart) and it ran like CHIT!
    JUST FYI , like I like to say IFC ( Ifya f*cken care )
