    Carb settings on Sl 750 ?

    Hey guys, as stated i need the stock carb settings for a Polaris sl750 93 Model.
    or better some carb setting for one with regular Powerfilters.

    I have a full Repair manual but the 93 Model isent listed, only 94 and above, and i have difiqulties understanding what it means, and how it is done, I know the Magneto/center/PTO

    In the manual for a 94 model.

    Highspeed 1 114m 3/8c 7/8p

    Lowspeed 1 12 Turn

    93 SL 750

    Main jet #77.5

    Pilot jet #72.5

    High speed screw 7/8M 1/2C 5/8P

    low speed screw 1/2

    idle speed in water 1250-1300

    pop off pressure 10-18 psi

    M stands for MAG (front)

    C stands for Center

    P stands for PTO (rear)


    If you're using a less restrictive Flame Arrestor than stock, you'll want to turn the highs OUT another 1/2 turn from stock settings.

    Remove the limiter caps from the high speed screws by just pulling them off. (high speed screws are mounted near the top of the carb) Refer to the Mikuni carb manual in post #7 of the Fuji fuel post in the tech section.

    Then turn the screws IN until they are LIGHTLY seated. DO NOT damage the tapered tips if the adj screws.

    From there, turn the screws OUT the specified number of turns (or fraction of turn). Then push the limiter caps back on.

    Do the same with the low speed screws.

    Turning screws IN when adjusting leans out the mixture. Turning them OUT will add fuel to the mix.

    What do you mean by Lightly seated? if i pull the high speed screw out and start from scratch?

    Don't turn them in until they are tight. Just to where the screw starts to give resistance.

    Remove the limiter cap on the high speed screw. Turn it all the way in (lightly seated) and turn it OUT the proper amount of turns. Then re-install the cap.

    Yes, from scratch.

    I this understanded correctly?
    """you take the screws turn them all the way in to they are seated, and turn the corect number of turns out,

    As for the correct turns

    7/8M - Means 7 out of 8 turns on the Mag carb
    1/2C - is the same like 50/50 = 4/8 Turns of the Center carb
    5/8P - Like the first one 5 turns out of 8 on the PTO carb.

    Sorry for my crappy english

    7/8M is almost 1 full turn of the front cyl

    1/2C is half of a full turn on the Center

    5/8P is a little more than half of a full turn on the rear
