What should idle speed be on Suzuki GS?
Once the idle mixture is correct, set the idle speed to 1200 RPM (or other speed as described in the shop manual) using the adjustment knob located between the airbox and the carburetors. Cylinder #3 should draw about 10 in Hg (24.5 cm Hg). This is your baseline measure.
What should I change in my Suzuki GS bike?
Replace the sparkplug in cylinder #3. Start the bike, and fine tune the idle mixture on #2. Loosen the locknut between #2 and #3 cylinders, and adjust the vacuum to 10 in Hg (25.5 cm Hg) for both cylinders. Tighten locknut being careful not to move the set screw.
What should the vacuum be on a Suzuki GS motorcycle?
Loosen the locknut between #1 and #2 cylinders, and adjust the vacuum to 11.25 in Hg (28.5 cm Hg) for #1 cylinder. Tighten locknut being careful not to move the set screw.
What should cylinder 3 draw in Suzuki GS?
Cylinder #3 should draw about 10 in Hg (24.5 cm Hg). This is your baseline measure. If the motor is not drawing this vacuum, double check that the idle RPM and mixture are correct; a rich cylinder will not create the full vacuum.

Can a blocked exhaust system be a carburetion problem?
A blocked exhaust system can mimic carburetion problems due to the lack of power, but the loud hiss from underneath the car from exhaust gasses trying to escape is the giveaway. Testing with a vacuum gauge will confirm a blocked exhaust system.
