Where is the idle adjustment on a 1996 Kawasaki Vulcan 800?

There is no idle adjustment screw on the 1996 Kawasaki Vulcan 800 because the idle is controlled by an Idle Air Control (IAC) valve. Adjusting the idle involves making changes to the settings of the IAC valve, which might require connecting the bike to a computer to make any changes. It's highly recommended that you consult a reputable motorcycle service manual or a qualified mechanic to perform this operation to ensure the bike operates properly and to prevent damage to the engine or other components.
