Periodic Maintenance Procedures
Coolant Level Inspection
Check the level when the engine is cold (room or ambi-
Lean the motorcycle slightly until the radiator cap is level
to the ground so that the radiator cap is located uppermost
in order to exhaust the air accumulated in the radiator.
Remove the radiator cap [A].
Remove the radiator cap in two steps. First turn the
cap counterclockwise to the first stop and wait there for
a few seconds. Then push down and turn it further in
the same direction and remove the cap.
Check the coolant level. The coolant level [A] should be
at the bottom of the filler neck [B].
If the coolant level is low, add coolant through the filler
opening to the bottom of the filler neck. Install the cap.
Permanent type antifreeze (soft water and ethylene
glycol plus corrosion and rust inhibitor chemicals for
aluminum engines and radiators)
Water and Coolant Mixture Ratio
Soft Water: 50%
Freezing Point: –35°C (–31°F)
Total Amount: 1.1 L (1.2 US qt)
For refilling, add the specified mixture of coolant
and soft water.
coolant and degrades its anticorrosion properties.
The diluted coolant can attack the aluminum en-
gine parts. In an emergency, soft water alone can
be added. But the diluted coolant must be returned
to the correct mixture ratio within a few days.
Coolant Deterioration Inspection
Visually inspect the coolant.
If whitish cotton-like wafts are observed, aluminum parts
in the cooling system are corroded. If the coolant is
brown, iron or steel parts are rusting. In either case, flush
the cooling system.
If the coolant gives off an abnormal smell, check for a
cooling system leak. It may be caused by exhaust gas
leaking into the cooling system.
Adding water alone dilutes the
