    slx 1200 piston wash

    Decided to take a peak and holy smoke! Am I way lean?
    Jettings and low screws are exactly at factory settings. Should I be looking at going up couple points on high jet because there's no high screw? Or is this normal wash for this ski?
    TIA,

    Yup it is! You sure got a pair of micrometer eyes

    Back to the jetting. I didn't have a magnifying glass yesterday so I was checking the jets with gage pins and thought they were at factory. (As some of you may have known, I just bought this ski and did not quite running through my 2nd gas tank yet.) So looking thru a magnifying glass these are my numbers:

    Main:
    Mag = 140 / Cen = 142 / PTO = 135 (exact factory setting)

    Mid:
    All = 42 (factory = 40)

    Pilot:
    All = 68 (factory = 65)

    Low screw turn out:
    Mag = 1-1/8 / Cen = 1 / PTO = 1 (factory = 1-1/8 )

    Adding the Mid and Pilot together, I am at 5 points over but why am I running so lean? The ski is complete stock

    On the first ride, the acceleration was very sluggish. It sounded rich so I turn the low screws 1/4 turn in and it did help. It still does not have that hard accel but I figure just let it running a tad rich like that and dial in later once I've got a chance to check the wash. But as the pictures show .... Yikes! And I was expecting a rich wash

    So, here're the question I have:
    Does type of oil cause different wash condition? The ski has Polaris Gold and I kinda like it because it does not smoke as my SL650 with synthetic oil. But it seems the build up on the head cap is kind of rubbery and can be scrape off easily with finger nail, not as hard as Penzoil on the SL650. I'll pop the SLS650 and confirm this later.

    If jumping up next size jets is my only option, then how many points should I go up? I assume I'll only need to up the Main only, right?

    TIA,

    Your choice of oil isn't really going to affect wash pattern.

    Yes, you're lean on all 3 cyls as mentioned.

    I'd suggest going back to specs on the low and mid jets, and raising the Hi. I believe that will help with the bottom end hesitation, and get your wash closer to what you're looking for.

    What's your max RPM reading on this one?

    Did you go through the carbs and make sure there's no obstructions?

    Thank you xlint89.
    Yes, I'll go back to specs and raise the Hi as you suggested. Figure it'll be easier to trouble shoot it.

    It maxes out @6700 RPM. Even though RPM limiter is at 7200, but 6700 is where this ski should be correct?

    Yes I did go through the entire carb rack and pumps. Did find a bit of slush at return line (mid carb), right before fuel constrictor. Didn't think that would be the culprit.

    I believe 6700 RPM is where the 1200 should be. Hopefully 1 of the more knowledgabe domestics will confirm this for you.

    The green goo does form inside the Tempo fuel lines. You need to watch out for that crap when you get a new ski.

    Just make sure to write down your carb settings right now. Just in case you ever need to return them later.

    Yup, replacing the fuel lines is too on my agenda.
    It's funny how one thing leads to another. I was just trying to check the wash with a flex-light but could not quite make it out thru the spark plug hole. Of course it was all black that's why LOL.
    So I figure just pop the heads off for better visual. Then ... too lean .... Hm .... better check the carbs ... Ah, what the heck, why don't I just go thru the whole carbs. Finished the carbs then .... Well, maybe I should check the reeds too .... just a few more screws ....
    At the rate I'm going, I think I'll be riding a spanking fresh ski this weekend LOL
