Electronic Power Control System (Epc) - KTM 400-660 LC4 1998-2005 Repair Manual

Electronic Power Control System (EPC)

Main components of the EPC system:
FUNCTIONAL CHARACTERISTICS:
The EPC system is not activated during normal operation of the motorcycle.
It is, however, activated as soon as the throttle is fully opened at a speed of 45 - 55 km/h while the second or third gear are
engaged.
The EPC control device opens the solenoid valve, directing an appropriate flow of fresh air onto the upper side of the slide
membrane of the constant-pressure carburetor, thus reducing the opening speed of the slide. This mechanism significantly reduces
the exhaust gas emissions of the vehicle.
SOLENOID VALVE
– Constant-pressure carburetor
– Control device
– Solenoid valve
– 2 contact screws at the engine
