2.22REAR SHOCK ABSORBERS
GENERAL
When removing the shocks for repair or replacement, remove
and install one shock first, then the other. This will eliminate
the need for raising the rear end of the motorcycle. If it is
necessary to remove both shocks at once, place the motorcycle
on a center stand with the rear wheel raised off the ground.

INSPECTION
NOTE
Shocks are non-repairable items, except for the rubber
mounting bushings. If the shock is leaking or damaged, it must
be replaced as an assembly.
1. Examine the rubber mounting bushings for cracks or wear.
Examine the shock for leaks.The unit should not leak and
should compress slightly easier than it extends. Compare
the action of the shock with a new one to judge if it is worn.
Replace the shock if necessary.
2. Clean and examine the shock mounting hardware. Replace
parts that are worn or damaged.
