The fuel injection system, used on C50 and M50 models, consists of the fuel tank, incorporating the fuel pump and filter, the fuel hose to the fuel rail on the throttle body, and the injectors that are located in the throttle body. All models have a dual valve throttle body with one injector per cylinder.

The fuel pump is activated initially by the ignition switch and continues to deliver fuel while the engine is running.

Fuel pressure is controlled within the pump by a pressure regulator. In the event of the machine falling over, a tip-over sensor cuts power to the fuel pump, injectors and ignition coils.

The entire fuel injection system is controlled by the engine control module (ECM) which monitors data sent from the various system sensors and adjusts fuel delivery to the engine accordingly.

If a fault develops in the injection system, the FI warning LED illuminates on the instrument cluster and an LCD code is displayed. In the case of a minor fault the engine will continue to run enabling the machine to be ridden, although performance will be significantly reduced.

For comprehensive fault diagnosis and certain service procedures, a Suzuki mode select switch (Part No. 09930-82710) is useful (and inexpensive), though not essential as its function can be copied using a simple jumper wire as described later in this Chapter.
