Piston Wear Inspection
Piston Ring Groove Width InspectionFuel Pump Relay Inspection
Refer to the Relay Circuit Inspection in the Electrical System
chapter.
If the fuel pump relay is normal, check the wiring to the
fuel pump relay (see Fuel Pump Relay Circuit).
Special Tool - Hand Tester: 57001-1394
If the wiring is good, check the ECU for its ground and
power supply (se ...
Starter Clutch Inspection
Remove:
Torque Limiter Cover (see Torque limiter Removal)
Turn the torque limiter [A] by hand. The torque limiter
should turn forward freely [B], but should not turn backward.
If the starter clutch does not operate as it should or if it
makes noise, go to the next step.

Coolant Level Inspection
NOTE
Check the level when the engine is cold (room or ambient
temperature).
Check the coolant level in the reserve tank [A] with the
motorcycle held perpendicular (Do not use the sidestand).
If the coolant level is lower than the “L” level line [B], remove
the upper fairing assembly (s ...
