Air Intake System

Air is drawn from the air cleaner through the throttle plates and into the engine. A potentiometer connected to the throttle pulley converts the throttle angular position into a voltage signal that is transmitted to the electronic control unit. A vacuum operated switch and a micro-switch also provide throttle position information to the electronic control unit.
