Periodic Maintenance Procedures
Cooling System
Coolant Level Inspection
                               NOTE
    ○Check the level when the engine is cold (room or ambi-
      ent temperature).

• Check  the coolant level in the reserve tank [A] with
  the motorcycle held perpendicular (Do not use the side
    stand).
    If the coolant level is lower than the “L” level line [B], re-
    move the right fuel tank cover (see Fuel Tank Cover Re-
    moval in the Frame chapter), and then unscrew the re-
    serve tank cap and add coolant to the “F” level line [C].
      “L”: Low
      “F”: Full
                            NOTICE
    For refilling, add the specified mixture of coolant
    and soft water. Adding water alone dilutes the
    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.
    If coolant must be added often or the reservoir 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.

Cooling System Inspection
Water Hose and Pipe Inspection (coolant leak, damage,
installation condition)
○The high pressure inside the water hose can cause
  coolant to leak [A] or the hose to burst if the line is not
  properly maintained.
• 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]
  are noticed.
• Check that the hoses are securely connected and clamps
  are installed correctly.
    Torque - Water Hose Clamp Screws: 3.0 N·m (0.31 kgf·m,
               27 in·lb)

Coolant Change
                            WARNING
    Coolant can be extremely hot and cause severe
    burns, is toxic and very slippery. Do not remove
    the radiator cap or attempt to change the coolant
    when the engine is hot; allow it cool completely.
    Immediately wipe any spilled coolant from tires,
    frame, engine or other painted parts. Do not ingest
    coolant.
