89 Hawk GT Carb issues

[Old_bashturd]

89 Hawk GT all stock with just under 10K.
I kept having an issue with jets clogging. I would clean it and bike would start but ran rough and revs would stay high when reving and closing throttle. Tore down the carbs and discovered the float screen in each was missing. I installed a new carb kit, with screens this time and new fuel filter. Started fine but revs continued to float and could hear an intermittent card burp/cough. Tried the old carb spray at the intake boots trick and it rpm increased when I sprayed them down. Ordered new intake boots from Nord and installed. Runs much better, road tested and it ran pretty good. Question is, It still floats when closing the throttle at about 1800rpm for about 10 seconds, then returns to about 1100 rpm. Any ideas what I should look at next?

Thanks in advance

That's called a "handling idle" and is a symptom of a lean mixture.

What are your idle bypass screws set to? (Not the idle stop on the one carb, the individual screws at the base of each that some people call the idle mix, some people call the fuel screw, and still others call it the air screw.)

Opening the screws should help. Setting them with the proper procedure from the manual will help more.

Thanks for the reply, they are both set 1 1/2 turns out. I'll give the that a try.
Thanks again

parc is right on target. open the screws counter-clockwise in 1/2 turn increments until the high idle returns more quickly. best done with an engine at operating temp.

might be a good idea to drain and flush the fuel tank too.
