    isnt factory jetting real rich so you dont risk blowing the engine during the break in period?

    I believe thats what the manual says firecat.

    I finally got my kill switch working properly. I couldn't kill the motor because I had some wires crossed. So hopefully I can sneak out to a wide open haul road so I can do a correct chop sometime during the weekend.

    I think we should make a new thread about spark plugs in the mad scientists lair...
    Billy... I still wanna talk about my burned up leg!!!

    What you want to do is put in a jet you know is too rich and makes the bike break up in the top end rpm. Then once you know your running rich just jet down the mains until it runs "clean." Confirm the way its running from plug chops. ONce its "clean" or not breaking up in the top rpms and you know your safe from cooking the motor then you can fine tune it which is a little harder with the 10 unit increase Mikuni jets.

    Do all this after you have the rings seated.

    Will it just shut off when your riding... or bog then die? or run normally but won't start if you shut it off? Can someone be more specific.

    The reason i ask is I was riding it and I stalled it. (too high a gear going too slow) It fired back up but would only bog a few feet then die again. I pulled the plug and it looks somewhere inbetween the wet and dry fouled plug pics huffa posted on that chart.

    You just learned one of the cardinal rules of owning a 2-stroke. Never leave the house without at least one spare plug and a wrench.

    LOL... I've only ever owned 4 strokes and never fouled a plug in 20 some years of riding.. This is indeed a new learning experiance.
