Periodic Maintenance Procedures
Idle Speed Inspection
Start the engine and warm it up thoroughly.
At first the engine will run fast to decrease warm up time
Gradually the fast idle will lower to a certain RPM auto-
matically. This is the idle speed.
With the engine idling, turn the handlebar to both sides
If handlebar movement changes the idle speed, the
throttle cables may be improperly adjusted or incorrectly
routed or damaged. Be sure to correct any of these
conditions before riding (see Cable, Wire, and Hose
Routing section in the Appendix chapter).
Operation with improperly adjusted, incorrectly
routed or damaged cables could result in an unsafe
riding condition. Follow the service manual to be
make sure to correct any of these conditions.
Check the idle speed.
If the idle speed is out of the specified range, adjust it (see
Idle Speed Adjustment).
Standard: 950 ±50 r/min (rpm)
Idle Speed Adjustment
This motorcycle is equipped with the ETV (Electronic
Throttle Valve) system to control the throttle valves elec-
trically. The idle speed is adjusted automatically at the
specified value [950 r/min (rpm)] by the ETV system.
Therefore, it is not necessary to adjust the idle speed
The idle speed can be adjusted by operating the right
handlebar switch housing.
Set the gear position in the neutral.
Start the engine and warm it up thoroughly until the water
temperature goes up 60°C (140°F) or more.
Wait until fast idle speed lowers to a certain value.
