2-62 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
Push the seal assembly into the rear shock body until it
just clears the circlip groove.
Check the circlip.
If it is deformed or damaged, replace it with a new one.
Fit the circlip [A] into the groove in the rear shock body
If the circlip is not a certain fit in the groove in the
rear shock body, the piston rod assembly may come
out of the shock absorber when injecting the nitro-
gen gas or riding the motorcycle.
Pull up the piston rod assembly [C] against the circlip.
Force the stop [D] into the rear shock body by lightly tap-
ping around the edge of the stop with a mallet.
Insert a suitable jig to center of the reservoir cap, and
operate the piston rod assembly after poor 98kPa (1.0
kgf/cm², 14 psi) nitrogen gas, and then push out to the
place where the reservoir cap hits the circlip. Now, check
that the edge of the reservoir cap is pushed out to 2 mm
(0.08 in.) deeper than the edge of the gas reservoir.
Oil leaking from the shock or reservoir diminishes
shock performance and may cause adverse han-
dling and/or shock performance. If the reservoir
cap is not pushed out to its specified position, oil
may spray out during pressurization and/or leak
Be sure the reservoir cap is in its
proper position before pressurizing the shock.
Check the rear shock body and gas reservoir for oil and
If there are no leaks, inject the nitrogen gas up to the 980
kPa (10 kgf/cm², 142 psi) pressure.
High pressure gas is dangerous and can explode,
causing serious injury. To avoid injury, have a qual-
ified mechanic pressurize the shock reservoir with
nitrogen gas only. Do not use air or other gases,
since they may cause premature wear, rust, fire haz-
ard or substandard performance.
Install the spring and spring guide.
Install the rear shock to the frame.
Adjust spring preload.
Install the parts removed (see appropriate chapters).
