I have a 81 Suzuki Gs 550 that idles too high, and not matter what I do with the carbs, it just won't run right. I went and got carbs off of an 850, and was told that they would work, but still ca

the idle adjustment screw is located between the number 2 and 3 carburator float bowls bottom rear. I can bairly get my hand on it, but found that a flat blade screwdriver works fine for making ajustments. backing out the screw lowers the idle speed, while running it in increases it. To adjust make sure the motor is warmed up and the choke is off. Make adjustments from the right side (looking at bike from the back), by pushing with the screwdriver on the knurals of the adjustment knob, pushing knurals up backs the screw out, conversly down runs it in. Try for around 1000 rpms for your set speed. You want it to idle smooth and low, but you want it set so it won't die out when you come to a stop when you are riding. If you can not get the idle in this range, then there is some other problem needing attention. However, the idle at times may run a little bit higher than normal when you come to a stop after a hard ride, and should return to normal set speed after it cools down some. You should also make sure that the throttle cable is set at the proper tenion, if too tight, you won't be able to lower the idle. you may have to make adjustments a few times to get it right.

If it is running like that with new fuel the problem could be plugged idle jet circuits. The carburetors will have to be removed, opened and cleaned. You will need compressed air for this job. Good idea to replace all 'O'rings inside carb at this time.
