ENGINE IDLE SPEED

• Inspect the idle speed after all other engine
maintenance items have been performed and are
within specifications.
• Before checking the idle speed, inspect the following
items.
– No DTC and MIL blinking
– Spark plug condition (page 3-8)
– Air cleaner element condition (page 3-7)
• The engine must be warm for accurate idle speed
inspection.
• This system eliminates the need for manual idle
speed adjustment compared to previous designs.
Turn the ignition switch ON and engine stop switch " ".
Start the engine and let it idle.
Check the idle speed.
IDLE SPEED: 1,200 ± 100 min
If the idle speed is out of the specification, check the
following:
– Intake air leak or engine top-end problem (page 10-
4)
– Throttle operation and freeplay (page 3-5)
– IACV operation (page 7-22)

RADIATOR COOLANT

Check the coolant level of the reserve tank with the
engine running at normal operating temperature.
The level should be between the "UPPER" and
"LOWER" level lines with the motorcycle in an upright
position.
If necessary, add recommended coolant.
RECOMMENDED ANTIFREEZE:
High quality ethylene glycol antifreeze containing
silicate-free corrosion inhibitors
Remove the lower cowl (page 2-28).
Remove the reserve tank cap [1] and add the coolant to
the "UPPER" level line [2] with a 1:1 mixture of distilled
water and antifreeze (coolant preparation: page 8-6).
Reinstall the reserve tank cap.
Check to see if there are any coolant leaks when the
coolant level decreases very rapidly.
If the reserve tank becomes completely empty, there is
a possibility of air getting into the cooling system.
Be sure to remove any air from the cooling system
(page 8-6).
