MAINTENANCE
SPROCKET INSPECTION
Inspect the drive and driven sprocket teeth for dam-
age or wear. Replace if necessary.
Never use
a
worn chain on new sprockets. Both chain
and sprockets must be in good condition, or the new
replacement parts will wear rapidly.
Check the attachment bolt and nuts on the drive and
driven sprockets. If any are loose, torque them.
DRIVE CHAIN SLIDER
Check the drive chain slider for wear.
Replace the chain slider i f it is worn to the bottom
of
the wear limit groove.
Refer to section 13 for drive chain slider replacement.
BRAKE FLUID
CAUTION
Do
not mix different types of fluid,
as they are not
compatible with each other.
Do not allow foreign to enter the system
when filling the reservoir.
Avoid spilling fluid on painted, plastic or rubber
parts. Place a rag over these parts whenever the
system is serviced.
NOTE:
When the fluid level is low, check the brake pads for
wear (page 3-17). A low fluid level may be due to wear
of the brake pads. If the brake pads are worn, the
caliper pistons are pushed out, and this accounts for
WORN

CAP
a low reservoir level.
If the brake pads are not worn and the fluid level i s
low, check entire system for leaks (page 3-17).

voir is level and check the front brake reservoir level
through the sight glass.

the reservoir cap, set plate and diaphragm, and fill
the reservoir with
