Periodic Maintenance Procedures
The torque of fork top plug is specified to 30 N·m (3.0
kgf·m, 22 ft·lb) however, when you use the top plug wrench
(special tool) [A], reduce the torque to 90% of the spec-
ified value [27 N·m (2.8 kgf·m, 20 ft·lb)] due to the dis-
tance [B] between the center of the square hole, where the
torque wrench is fitted, and that of the octagonal hole of the
This torque value [27 N·m (2.8 kgf·m, 20 ft·lb)] is appli-
cable when you use a torque wrench whose length gives
leverage of approximately 310 mm between the grip point
to the center of the coupling square.

Rear Shock Absorber Inspection
Bounce [A] the rear of the motorcycle up and down and
check for smooth suspension stroke.
Remove the rear frame (see Rear Frame Removal in the
Check for a broken or collapsed spring.
Check the shock for a bent shaft or oil leaks.
If the shock does not smoothly or damaged, replace or
repair defective parts.
Rear Shock Absorber Oil Change
The oil should be changed in the rear shock absorber at
least once per racing season. The frequency for best per-
formance must be based upon riding conditions and rider
Remove the rear shock absorber from the frame (see
Rear Shock Absorber Removal in the Suspension chap-
Remove the shock absorber spring (see Spring Replace-
ment in the Suspension chapter).
Insert a suitable jig to center of the reservoir cap, and
release nitrogen gas completely (keep the dedicated jig
For instructions on how to use the jig, follow the operation
manual provided by the manufacturer.
Do not point the reservoir valve toward your face or
body when releasing nitrogen gas pressure. An oil
mist is often released with the nitrogen. Always re-
lease nitrogen gas pressure before disassembling
the rear shock absorber to prevent explosive sepa-
ration of parts.
