Idle adjust for a katana 600 2002

COULD BE A SMALL KNOB IN MIDDLE OF CARBS, A BIT CLOSE AND TIGHT.

An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The cars computer or PCM (powertrain control module) receives information from various sensors and will output signals to adjust the idle air control motor in or out to adjust engine idle speed by controlling engine idle air. An idle air control motor can fail one of two ways, either the motor short circuits and stops working or the motor will develop high resistance and cause the idle air control motor to react slowly, either failure can cause the engine to stall at idle. When a trouble code scan is performed it sometimes won't always detect a failed or weak idle air control motor.

Shot in the dark here without knowing the vehicle but it could be an Idle Air Control valve starting to fail. An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The cars computer or PCM (powertrain control module) receives information from various sensors and will output signals to adjust the idle air control motor in or out to adjust engine idle speed by controlling engine idle air.

When a trouble code scan is performed it sometimes won't always detect a failed or weak idle air control motor. To check the idle air control motor remove the unit, with the wires connected turn the key to the "on" position without starting the engine, the idle air control should move in or out. If the idle air control motor does nothing it has probably failed, replace it with a new unit and recheck system. Note: while the idle air control motor is removed clean (use aerosol carburetor cleaner) the passages the idle air control uses to control idle air speed, also inspect the idle air control for a build-up on the seating (pointed) end and clean as necessary.

Either the idle speed is set too low or the idle circuit in the carbs is still plugged up despite the previous cleaning.

Has the bike been sitting for any time longer than 4 days? 4 days is enough to clog idle jets. Cleaning the carbs if it has carbs, is the first defense against idle to low rpm stalls. Pull the carbs and clean them out. Definitley will help you out.

When you are on the bike and riding do you still have the choke out? And stop spraying starter fluid into the carbs..bad bad bad.... bikes start with out that stuff and if you need it then something is wrong.. your gonna mess something up doing that....let me know about the choke and we will go from [email protected]

It still sounds like it still running rich. If it doesn't have any performance mods like aftermarket exhaust it wont like the stage 3 kit. The stage 3 kit should be install if it has high performance exhaust and k&n pods instead of an airbox and filter. Or the floats may be stuck or improperly adjusted.

find the Idle air control valve on the side of the intake and then take off and clean or replace you could try taking a small ball peen hammer and tapping it lightly while it is idling let will genarly free them up

look on the left side of bike behind the fairing about where your knee would be look for a little knob rember righty faster idle lefty less idle speed be kind rate us
