OUTLINE
The main function of a fuel supply system is to provide fuel to the combustion chamber at the optimum air-fuel ratio in accordance with the engine operating conditions and the atmospheric temperature.
In the conventional carburetor system, the air-fuel ratio of the mixture that is supplied to the combustion chamber is created by the volume of the intake air and the fuel that is metered by the jet that
is used in the respective carburetor.
Despite the same volume of intake air, the fuel volume requirement varies by the engine operating
conditions, such as acceleration, deceleration, or operating under a heavy load. Carburetors that
meter the fuel through the use of jets have been provided with various auxiliary devices, so that an
optimum air-fuel ratio can be achieved to accommodate the constant changes in the operating conditions of the engine.
As the requirements for the engine to deliver more performance and cleaner exhaust gases
increase, it becomes necessary to control the air-fuel ratio in a more precise and finely tuned manner. To accommodate this need, this model has adopted an electronically controlled fuel injection
(FI) system, in place of the conventional carburetor system. This system can achieve an optimum
air-fuel ratio required by the engine at all times by using a microprocessor that regulates the fuel
injection volume according to the engine operating conditions detected by various sensors.
The adoption of the FI system has resulted in a highly precise fuel supply, improved engine
response, better fuel economy, and reduced exhaust emissions. Furthermore, the air induction system (AI system) has been placed under computer control together with the FI system in order to
realize cleaner exhaust gases.

FI SYSTEM
The fuel pump delivers fuel to the injector via the fuel filter. The fuel pump maintains the fuel pressure that is applied to the injector at only 324 kPa (3.24 kg/cm2, 46.08 psi). Accordingly, when the
energizing signal from the ECU energizes the injector, the fuel passage opens, causing the fuel to
be injected into the intake manifold only during the time the passage remains open. Therefore, the
longer the length of time the injector is energized (injection duration), the greater the volume of fuel
that is supplied. Conversely, the shorter the length of time the injector is energized (injection duration), the lesser the volume of fuel that is supplied.
The injection duration and the injection timing are controlled by the ECU. Signals that are input from
the throttle position sensor, crankshaft position sensor, intake air pressure sensor, intake air temperature sensor, coolant temperature sensor, and O2 sensor enable the ECU to determine the
injection duration. The injection timing is determined through the signals from the crankshaft position sensor and the cylinder identification sensor. As a result, the volume of fuel that is required by
the engine can be supplied at all times in accordance with the driving conditions.
Illustration is for reference only.

• How to erase the self-diagnostic fault code from memory:
If the ECU detects a normal signal upon the completion of the repair of the malfunction, the selfdiagnostic fault code disappears from the meter and is replaced by the normal clock display. However, the self-diagnostic fault code of the previous malfunction remains in the ECU memory as
part of the malfunction history. To erase the self-diagnostic fault code from the malfunction history,
the operation for diagnostic code 62 must be performed in the diagnosis mode.

SUBSTITUTE CHARACTERISTICS OPERATION CONTROL (FAIL-SAFE ACTION)
If the ECU detects an abnormal signal from a sensor while the motorcycle is being driven, the ECU
illuminates the engine trouble warning light and provides the engine with substitute characteristic
operation instructions that are appropriate for the type of the malfunction.
When an abnormal signal is received from a sensor, the ECU processes the specified values that
are programmed for every sensor, in order to provide the engine with substitute characteristics
operation instructions that enable the engine to continue to operate (or to stop its operation,
depending on circumstances).
The ECU takes fail-safe actions in two ways: one in which the sensor output is set to a prescribed
value, and the other in which the ECU directly operates an actuator. Details on the fail-safe actions
are given in the table below.

CHECKING THE FUEL PUMP
WARNING
@
Gasoline is extremely flammable and under
certain circumstances there can be a danger of an explosion or fire. Be extremely
careful and note the following points:
• Stop the engine before refueling.
• Do not smoke, and keep away from open
flames, sparks, or any other source of
fire.
• If you do accidentally spill gasoline, wipe
it up immediately with dry rags.
• If gasoline touches the engine when it is
hot, a fire may occur. Therefore, make
sure the engine is completely cool before
performing the following test.
1. Check:
• fuel pump operation
▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼
a. Fill the fuel tank.
b. Put the end of the fuel hose into an open
container.
c. Connect the battery (12 V) to the fuel pump
terminals as shown.
Battery positive lead → red/blue 1
Battery negative lead → black 2

d. If fuel flows out of the fuel hose, the fuel
pump is OK. If fuel does not flow, replace
the fuel pump.
