    2000 XL 1200 Limited Carb High Low Mixture settings

    I have the carbs off to do the drilled return modification. Id like to check the factory settings for the high/low mixture screws. Does anyone know what they are or have a sweet spot to shoot for? Everything is factory on the ski including the high/low jets. ***I do have a D-Plate installed.*** No plans for any modifications to the air intake. Any info is appreciated. Thanks

    Personally, if the carbs are pulled and cleaned every 3-4 years the drilled return mod isn't needed. Setting carbs to factory settings and doing full rebuilds with genuine mikuni kits and new genuine mikuni needles/seats will get them running factory fresh.

    Once you go past factory (IE better breathing air intake setups) is when you start seeing issues with needing to rejet and remove the accelerator pump.

    Factory settings on those carbs are as follows (per member on here, manual doesn't spec these settings...)

    Low's: front, center, & rear - 1, 1, 1, +/- 1/4

    High's; front, center, & rear - 3/4, 1, 3/4, +/- 1/4

    Main Jets: 117.5

    Pilot Jets: 87.5

    Needle Size: 1.2

    Thank You. I’ve been searching for days. Just want to keep everything stock. The motor is new. It actually runs really well except for a bog down when accelerating. Checking the mixture screws while I have them out just makes sense. Any chance you know the pop off range? It’s the dull silver spring. The carbs were just rebuilt. Now I can do them myself since I wanted to learn how everything comes out.

    They are stamped on the bottom side. When rebuilding don't skip replacing the oring on them. They like to get hard and shrink over time causing a pop off that wont hold pressure.

    I’m assuming the bottom of the seat? Does it come out with a needle nose? With a little twist pull?

    It won’t come out and now that it’s marked up from the needle nose it looks like I’ll be replacing. Any ideas to get it out?
