The Suzuki Bandit, a motorcycle manufactured since 1991, offers sport-standard power. Like all motorcycles, the Suzuki Bandit sometimes requires mechanical adjustment. The carburettor's float height must be adjusted periodically for the engine to run with enough throttle. Since all of the models of the Bandit vary slightly, refer to your instruction manual whenever you are unclear with a process or with the location of an engine part. Removing your carburettor requires careful action and should only be attempted by those familiar with the Bandit.

Turn the Bandit off, if necessary. Push the kickstand out so that the motorcycle is level. Grasp the fuel valve, located next to the carburettor, and turn it to the "Off" position. Pull the fuel lines attached to the carburettor away from the vehicle. Disconnect the lines and pull the carburettor away from the Bandit. Set it on a flat surface.

Insert a flathead screwdriver into the drain screw on the bottom of the carburettor. Unscrew it and set it aside. Drain the bottom of the carburettor. Remove the float bowl using a Phillips screwdriver.

Turn the carburettor upside down so that the flat faces upward. Remove the bowl's gasket by unscrewing it. Using a flat height gauge, measure the distance between the top of the bowl and the edge of the bowl's mating surface. This measurement should be 14.77mm if your Bandit is a model from the years 1996 to 2000. If your Bandit is a 2001 or 2002 model, the float height should be 13.0mm.

Adjust the float height. Bend the tang at the centre of the float. Grasp the tang with needle-nosed pliers and push it up or down. Bending the tang downward lowers the float height. Bending the tang upward increases the float height. Measure the float height using the float height gauge and compare it to the correct height. Adjust the height again, if necessary.

Reassemble the float bowl and reattach the carburettor.
