OUTLINE
The main function of a fuel supply system is to provide fuel to the combustion chamber at the opti-
mum air-fuel ratio in accordance with the engine operating conditions and the atmospheric tempera-
ture.
In the conventional carburetor system, the air-fuel ratio of the mixture that is supplied to the com-
bustion 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 con-
ditions 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 man-
ner. 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 sys-
tem (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 pres-
sure 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 dura-
tion), 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 tem-
perature 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 posi-
tion 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.

* Table of self-diagnostic fault code numbers displayed on meter
•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 self-
diagnostic fault code disappears from the meter and is replaced by the normal clock display. How-
ever, 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.

FUEL INJECTION SYSTEM
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.

Code No. 19 Symptom A break or disconnection of the black/red lead of the ECU is detected.
Used diagnostic code No. 20 (sidestand switch)
Inspection operation item and probable cause Operation item and countermeasure Reinstatement
method
Defective sidestand switch Replace if defective.
Refer to “CHECKING THE SWITCHES” in
chapter 8. (Manual No.: 5JW1-AE1)
If the transmission
is in gear, it is rein-
stated by retracting
the sidestand.
If the transmission
is in neutral, it is
reinstated by
reconnecting the
wiring.
Open circuit in wiring harness or sub lead. Repair or replace if there is an open circuit.
(Between ECU and black/red lead)
Connected state of connector
Inspect the coupler for any pins that may
have pulled out.
Check the locking condition of the coupler.
If there is a malfunction, repair it and connect it
securely.
