    Ultra/STXR carb ?

    i rebuilt my carbs last winter and my mag side piston is running a bit lean. i've ridden the thing maybe an hour all summer and i want to richen up the carb a tad before i sell the ski. i want to open the pilot a bit, but i can't see it with the carbs on. is there a way to adult the pilot without pulling the carbs off? thanks.

    My mag cylinder is running more rich than the other two right now but usually they are all the same. That indicates a problem with the other two carbs in my case.
    I don't really know what you are asking but the carbs are not adjustable. There may be a problem with the needle and seat, diaphragm or maybe even an air leak on that particular cylinder. I would fix the problem right away because a lean condition will destroy your engine.

    Yes, they're adjustable, no, you can't do it without removing the carbs. Keep in mind that this doesn't alter the high speed mixture.
