Periodic Maintenance Procedures

• Raise  the rear wheel off the ground with the stand (see
  Rear Wheel Removal in the Wheels/Tires chapter).
• Inspect  the roughness of the rear wheel bearing by push-
  ing and pulling [A] the wheel.
• Spin  [B] the rear wheel lightly, and check for smoothly
  turn, roughness, binding or noise.
    If roughness, binding or noise is found, remove the rear
    wheel and inspect the wheel bearing (see Rear Wheel Re-
    moval, Hub Bearing Inspection in the Wheels/Tires chap-
    ter) and coupling (see Coupling Bearing Inspection in the
    Final Drive chapter).

Final Drive
Drive Chain Lubrication Condition Inspection
  Lubrication is necessary after riding through rain or on wet
roads, or any time that the chain appears dry.
  Use a lubricant for sealed chains to prevent deterioration
of chain seals. If the chain is especially dirty, clean it using a
cleaner for sealed chains following the instructions supplied
by the chain cleaner manufacturer.
                           NOTICE
    The O-rings between the side plates seal in the lu-
    bricant between the pin and the bushing. To avoid
    damaging the O-rings and resultant loss of lubri-
    cant, observe the following rules.
    Use only chain cleaner for cleaning of the O-ring of
    the drive chain. Any other cleaning solution such
    as gasoline will cause deterioration and swelling
    of the O-ring. Immediately blow the chain dry with
    compressed air after cleaning. Complete cleaning
    and drying the chain within 10 minutes.

• Apply chain oil to the sides of the rollers so that oil will
  penetrate to the rollers and bushings. Apply the oil to the
    O-rings so that the O-rings will be coated with oil.
•   Wipe off any excess oil.
