3 turns open means really bad hanging idle. I know what the screws adjust, have synced to straight across the board. Maybe I’ll try my blue tune and see what I get.

Yes, the hanging idle comes from burning off the excess fuel when the throttle is closed. The carbs as stated have the stage 1 treatment, so normal input does not always equal normal results when tuning.

Yes and no. If I turn my pilots more than 11/2-13/4 turns out I get a hanging idle, idles good at 11/2 turns. Go figure

What is the color @ 1.5 turns out and 3.0 turns out?
Pilot screws have good o-rings?
At 3 turns out do you think the pilots are sucking air?Jim, in Central New York State.

I did that that is how I know what it does. Doesn’t even want to run 3 turns out. Fresh O rings and seals. New intake pipes. Possible throttle shaft seals as Big T throws out. Have not ridden since last adjustment or looked at the plugs yet.
