Periodic Maintenance Procedures

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
Frame chapter).
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
ability.
Remove the rear shock absorber from the frame (see
Rear Shock Absorber Removal in the Suspension chap-
ter).
Remove the shock absorber spring (see Spring Replace-
ment in the Suspension chapter).
Point the valve [A] away from you. Slowly release nitro-
gen gas pressure from the gas reservoir by pushing down
the valve core with a screw driver.
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.
Adjust the gas reservoir damping adjusters [A] to the soft-
est position.
Remove the air bleed bolt [B] and pump the rear shock to
drain the oil out the rear shock body.
Install the air bleed bolt.
