    About Randys tuning tips for girls

    Thanks to everyone that has helped me with my rebuild with there time and Knowledge you guys are great.

    my ski
    94 slt 750
    sbt long block (did not know of this site before purchase fingers crossed)
    boysen reeds
    rebuilt 780 carbs with orig Mikuni kits rejetted for a 750
    Primers choke plates removed
    780 reed spacers
    780 intake and fa
    new Mikuni tripple outlet fuel pump
    every fuel line replaced even in tank
    new sea doo fuel vavle
    odyessy battery
    new pump bearings
    AND A LOT OF TIME
    AND A FEW DOLLARS


    Question is in randys tuning tips for girls the first sentance says

    Start with the screws set at 1 turn out, and tune with the tachometer for peak Rpm,

    I assume he is talking about high speed screws is this correct?
    and I assume my low speed screws should be set at factory to begin?

    putting it in the water for the first time tomorrow and would really not have to come back and ask you guys how to replace piston tomorrow evening.
    thanks again to all.

    Nice build. You've really been doing your homework.....

    Do you have new pistons that you need to break in? If so, then make sure to break in the rings before trying to tune for max RPM.

    Yes, start with the lows set to factory specs. (might as well start with the highs set to spec too)

    Try and adjust the highs for max RPM and write down the settings.

    Then adjust the lows for a strong take off. Combine the 2, and readjust for peak RPM again.

    Follow Randy's instructions and you should be fine.

    When tuning for peak RPM, you don't need to go long. Just a 50 yd burst should reveal peak RPM.

    Remember trying to tune in choppy conditions will prove to be difficult.

    Take your spark plug wrench with you if you're going to do any plug chops.

    Good luck and let us know how it goes.

    take a spare spark plug as well.seems like around 2200 rpm is where the low jet does the feeding.if it stumbles (not the same as falling flat) and you turn the low in a 1/4 turn and it gets better then the low is rich.the low adjuster is really to control the idle mixture but affects the mixture at other settings as well.build from the bottom up on jets.once you get the low right the highs are much easier to figure out.

    Thanks Xlint and all......... It runs like a scalded dog with its balls on fire........ put in sat morning it was over cast and and looked like rain which made everyone else stay home lake was like Glass.....forgot to tighten exhaust hose and after wondering where where the #%&@ all the smoke was coming from for like 20 mins I found it felt like a fool slipped hose back on and tightned up ..good to go. then went through break in and carb adj it took like an hour ... need to get bore scope to check wash tried with flexible led light my old eyes are not as good as they once was... gonna pull heads tomorrow and take a peek will post pics and get everyones opnion...now I want pissers jus because I think it would be good to know without a doubt that water is flowing...put a few hrs on motor the lake I was at is 6 miles long ran back an forth several times still have not run all out full throttle average 4500 rpms gonna carry it out again this weekend.

    Awesome, sounds good.

    But you are going to have to do some WOT passes (short bursts) to get an accurate wash pattern.

    Within the next few weeks will transform exterior of ski. seat cover,floor mats,paint hood an nose,maybe just a simple Polaris sticker on each side.What can be done with rub rails? And again thanks all and anyone doing this dont quit you will get there this has taken some time but it did pay off.
