  • 2000 yamaha 1200 XL mixture settings

    I have a 2000 yamaha 1200 XL with power valves. Its stock except for D-plate (cat removal) and free flow exhaust. Stock pipe.


    The stock mixture screws on the pto carb were 0 on both high and low. Any idea why? (The stock M&C high were at 1 1/4 and low at 5/8 and 3/4.)

    What mixture screw settings do you recommend if I leave the accelerator pump (which is connected to the mag and pto carbs) enabled?

    M C PTO

    H

    L

    Why would I disable the accelerator pump and would this change the mixture screw settings?

    I don't think I will be able to reach the mixture screws after everything is back in place.

    thanks much,
Working...
