    Damn Dude! that sucks. I'm running stock 750 jetting, right out of the book but I don't remember offhand, with 1/4 turn extra open on all 3 hi screws to prevent burn-down. That was totally stock, but now with the HotSeat waterbox my ctr looked a touch lean.

    Z are you using the PRO CDI?
    Alot of advance at cruising may have caused your freholie.

    Her ride last year with OP F/A's, PRO CDI, and PSI dry pipe was 122.5M, and 120 CEN,PTO. With 85 lows

    This year, for unforseen reasons, I had to increase jetting to 125 across the board with 85 lows. Runs really well like this. Turned a 54 MPH on GPS with the flatest water I've ever run on.

    I was running the pro! and your Her ski specs! I rode it for a few minutes trying to figur if it was looking for more fuel or getting too much
    By the time I had it adjusted all the way rich I knew it wanted more fuel
    but apparently too late so I just finished replacing the piston and I am going to order some bigger jets

    Wow, holed the CEN with a 120 main jet?

    How'd the other 2 look?

    Interestingly enough, "her ride" needed larger jets on the CEN and PTO this year.

    the other 2 are fine! but I didn't get much to look at with only 10 min ride probably more like 5 min and 4 of those were just above idle
