Setting Up Round Slide Mikuni's On a 91 Phazer?

I had a new 1990 Phazer II, so it's been a while. I did find an old book with a little info. You need to locate the pilot air screws on side of each carb. Turn these in until lightly seated, and back out 1 1/2 turns. You set idle speed by turning the throttle stop screw in (increase) or out (decrease) until your idle speed is 1600. You do need the vacuum gauge to sync properly. It is connected to the intakes under the rubber caps and set at a fast idle to have the same reading for both carbs.

Turning the idle screw will raise and lower the slide.

Hope this helps!
