Periodic Maintenance Procedures
Coolant Level Inspection
Check the level when the engine is cold (room or ambi-
Check the coolant level in the reserve tank with the mo-
torcycle held perpendicular (Do not use the sidestand).
The coolant level should be between the "F" (full) level
line and the "L" (low) level line (In the photo, the left side
cover has been removed for clarity).
Reserve Tank [B]
"F" Level Line [C]
"L" Level Line [D]
If the coolant level is lower than the "L" level line, remove
the left side cover (see Side Cover Removal in the Frame
chapter), and then unscrew the reserve tank cap, and add
coolant to the "F" level.
For refilling, add the specified mixture of coolant
and soft water.
coolant and degrades its anticorrosion properties.
The diluted coolant can attack the aluminum engine
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.
If coolant must be added often or the reserve tank
has run completely dry, there is probably leakage in
the cooling system. Check the system for leaks.
Coolant ruins painted surfaces. Immediately wash
away any coolant that spills on the frame, engine,
wheels, or other painted parts.
Radiator Hose and Pipe Inspection (coolant leak,
damage, installation condition)
The high pressure inside the radiator hose can cause
coolant to leak [A] or the hose to burst if the line is not
Visually inspect the hoses for signs of deterioration.
Squeeze the hoses. A hose should not be hard and
brittle, nor should it be soft or swollen.
Replace the hose if any fraying, cracks [B] or bulges [C]
Check that the hoses are securely connected and clamps
are tightened correctly.
