Check the bushing [1] of the rear cover for wear or damage.

 

Replace the starter motor as an assembly if necessary.

STARTER RELAY SWITCH

 

INSPECTION

 

Remove the left side cover (page 2-3). Shift the transmission into neutral.

Turn the ignition switch ON and engine stop switch " ". Push the starter switch.

 

The coil is normal if the starter relay switch [1] clicks.

 

If you don't hear the starter relay switch "CLICK", inspect the starter relay switch using a procedure below.

GROUND LINE

 

Disconnect the starter relay switch 4P (Red) connector [1].

Check for continuity between the following terminal of the wire harness side and ground when the starter switch is pushed.

 

CONNECTION: Green/red – Ground

 

If there is continuity under following conditions, the ground circuit is normal.

 

– When the transmission is in neutral (In neutral, there is a slight resistance due to the diode.)

 

– When the transmission is in gear with the clutch lever pulled in and sidestand retracted

 

STARTER RELAY INPUT VOLTAGE

 

Connect the starter relay switch 4P (Red) connector [1]. Turn the ignition switch ON and engine stop switch " ".

Measure the voltage between the following terminal at the starter relay switch 4P (Red) connector and ground.

 

CONNECTION: Yellow/red (+) – Ground (–)

 

STANDARD: Battery voltage

 

If the battery voltage appears only when the starter switch is pushed with the ignition switch ON and engine

 

stop switch " ", the starter relay input voltage is normal.

OPERATION CHECK

 

Remove the starter relay switch (page 6-9).

 

Connect a fully charged 12 V battery to the starter relay switch as shown.

 

There should be continuity between the cable terminals when the battery is connected, and no continuity when the battery is disconnected.

 

 

REMOVAL/INSTALLATION

 

Remove the left side cover (page 2-3).

 

Disconnect the battery negative (-) terminal (page 19-4).

 

Disconnect the starter relay switch 4P (Red) connector [1].

 

Release the starter relay switch [2] from the air cleaner housing.

 

Pull back the rubber cover [3]. Remove the bolts [4] and cables [5].

 

Remove the starter relay switch from the stays with the shock rubber.

 

Remove the starter relay switch from the shock rubber. Installation is in the reverse order of removal.

 

NEUTRAL DIODE

 

INSPECTION

 

Remove the left side cover (page 2-3).

 

Open the fuse box cover and remove the neutral diode [1].

 

Check for continuity between the neutral diode terminals.

 

When there is continuity, a small resistance value will register.

 

If there is continuity, in direction shown by the arrow, the neutral diode is normal.

SERVICE INFORMATION

 

GENERAL

 

• Work in a well ventilated area. Smoking or allowing flames or sparks in the work area or where gasoline is stored can cause a fire or explosion.

• Do not snap the throttle valve from full open to full close after the throttle cable has been removed. It may cause incorrect idle operation.

 

• Bending or twisting the control cables will impair smooth operation and could cause the cables to stick or bind, resulting in loss of vehicle control.

 

• Do not damage the throttle body. It may cause incorrect throttle valve operation.

• Seal the intake ports with tape or a clean cloth to keep dirt and debris from entering the engine after the throttle body has been removed.

 

• Prevent dirt and debris from entering the throttle bore and air passages after the throttle body has been removed. Clean them using a compressed air if necessary.

• Do not loosen or tighten the white painted nut and screw of the throttle body. Loosening or tightening them can cause throttle valve and idle control failure.

 

• For fuel level sensor inspection (page 20-15).

• Before disconnecting the fuel feed hose, relieve fuel pressure from the system by disconnecting the quick connect fitting from the system (page 7-4).
