I just got done overhauling the carbs on the bike. I didnt change the sync screws, and set the mixture screws to the correct turns according to the manual. I set the throttle stop screw to where it isnt protruding at all. The bike is sitting at 3-4k rpms when its warm. I tried to do the idle drop, but turning the mixture screws dont change the idle in the slightest.
The only difference is with the screws the whole way in theres back fire in the exhaust from the mixture being so rich. I was gonna start messing with the sync screws but dont want to mess anything up too bad.
Other than the idle the bike runs amazingly. No popping and sputtering like it used to.

Idle drop would be done at idle speeds. My bet is that a bench sync was not done.

You are correct. I was doing so researching after i had posted this and found out about how to do that I'll see about doing that today.

I was doing the "bench" sync found out the #3 carb throttle was stuck between the location spring so it was open more than the others. Flung the spring across the garage after 30 minutes of swearing and looking for it found it under the bike. Replaced the correct way. Continued the "bench" sync, got it back together. Now it works perfect. Time to get a vac gauge and do a real sync.
