    What do you mean by busted??
    Shorted out?
    Center Electrode Break?
    Cap un-screw?

    If you're running pre-mix is it at 40:1?
    Does another set of plugs allow your engine to run?

    Unless you have some good gas, I would run 8's . If you are fouling 7's though you will definitely be fouling 8's quicker as they are a colder heat range than the 7's . You are using BPR#ES right? #=7 or 8.

    yes, new set of plugs will start my skii immediatly,im using 40 liter gas to 1 liter oil, before im using bpr8, im having difficult starting, its better for me to use b7 for me...the skii starts quickier.

    how about my highspeed jet #105
    lowspeed jet #75

    is this right? for stock??

    i have a load i think rich from 0 to 50% throttle

    and i also observe when i have somebody ride with me on my skii, it won't rev high it will load up...
