    Piston Wash w/ PICS

    1995 Polaris 750SL piston wash readings.
    How many turns to get these right for safe rec riding?? I plan to pull a tube or skier this summer, so I need to have room for an extra load.

    From what I've read, I need to richen up the Center (it's been a little warmer to the toch as well), but how much? what about the PTO & MAG ?? I am turning 6250 RPM @ 45mph on the MFD. Ocean pro ride plate (Ocean version) is the only upgrade. (reason for top end speed loss- but now I can ride in choppy water).

    First readings since the rebuild of the carbs! (thanks to the green hulk help!!) Run on regular pump gas. This was a nice 20 minute ride at WOT and then pulled the stop cord. I had to start it back up and idle to the dock (15 seconds at most)

    What do you think??

    1 is too rich
    2 is too lean
    3 looks ok,a little wet but safe

    Are your carb main jets on top on your ski?

    How much should he turn each carb's high speed adjustment screw?

    High speed adjustments are on the top for this ski.

    Did you do a pop off test? All 3 high speed screws in the same spot?

    I'm guessing they were the high speed screws that were on the sides of the carbs (near the top). They had a little blue cap that fit over the screw. It allows about a 1/4 turn before the tab catches. If they need more than a 1/4 turn, I will have to take those little blue cap covers off the screws. Those caps have teeth that catch on the outside of the adjustment screws. Makes it easier for adjusting by reaching down with your hand and not using a screw driver.

    I had to take it to the local shop to do the pop off test, and they said it was fine. They set those screws to the factory specs in the manual.

    I'd go in a 1/4 on the mag, and watch it. 1/8 turn out on center, and leave the pto alone.(high spd adjusters)
