    LOL. Yup, been there before. Crack beers give the sxi a hop and smoke all my buddies down the lake!
    The 80mm nozzle came stock on the early 750 sx and I think other early 750 sit downs. You can tell by how thin the reduction nozzle appears. I'm assuming your is the stock 76mm from the sxi pro. the casting looks pretty thick. I'll check ebay real quick.

    Spend the time tuning the carbs. Your set up is good just needs time and patience. Have you read the Mikuni tuning tips? Helped me out a ton.

    Theres a big thread on here about reverse jetting those mikunis. May be something to look into. Also if you have choke plates on them, you can try accelerating with 1/2 choke and see if the problem gets better or worse - to give you an idea of which way to solve the problem. Same if you have a prime, just juice it mid take off and see what happens. 2 turns out means you should be looking at a size up in jets if you need more fuel.

    i have primers, when you say mid take off, like grab a bunch of throttle and right after hit the primer, dies of to much fuel performs better not getting enough fuel? am i understanding that correct.

    yea, pump the primer while you are trying to plane out and see if it helps or hurts.
