Question about Suzuki GSX 750 F (Katana Motorcycles
Posted by Anonymous on
Check the fuel level in the float chambers of the carbs, it could be too low! Readjust the float to obtain correct level. Blow out the primary and main jets with compressed air.
Hope you adjusted the air screw mixture at the right temperature of the engine i.e. you need to warm it up and than adjust also check the valve clearance of the engine.
Hope this helps

Very good thought process on the adjustments. The throttle screw sets the idle speed and the air screw sets the fuel mix at idle speed. The stock setting is 1.5 turns outward. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward.
From this point you adjust the idle speed then adjust the air screw for fastest idle speed at that throttle screw setting. If the idle speed becomes faster than desired after adjustment, just reset the throttle screw and then reset the air screw.
A “very helpful” rating for this answer? Thanks!

the fact that it idles with the choke on indicates that fuel mixture is the problem here remove the mixture screw completely check that the o ring seal is not damaged & that the end of the needle is not worn or bent if either of these conditions are obviouse replace the damaged or worn parts general rule of thumb with mixture adjustment is 1&1/2 to 2 turns out give it a try

I would be checking for air leaks, this will give you a lean mixture. In particular look for the seals for the balance tubes and each carb.
