rich all 4.
I have a 1981 gs750l with the air screws on top near air filter. which way do I turn them for rich or lean? all four are running rich with smoke. I've been battling this bike with issues since I got it. I replaced the petcock. adjusted the valves. adjust tooth timing. rebuilt carbs. checked for leaks replaced exhaust gaskets. among other.Tags: None

out makes it richer in makes it leaner. It may be a problem bigger than just turning a screw :-D. You may need to do some serious jetting.

I'm not sure of the exact #, but I believe that 1 and a half to 2 turns out from all the way in is normal for a stock air box and exhaust. Once you get this setting figured, you should use a manometer to synch the carbs.

I was just syncing today adjusting the mixture screw wont change sync unless your really far off. If you just moving it < (less than) 1 turn you should be fine

thanks for all the help. after I moved them to 1 and half. I ran it in the yard for a few cut it off at idle and checked one plug. It was obviously still sooty, but it looked like it was trying to tan up a bit. I quit cause it was getting dark.
