worn seals. Rebuildable shocks should be refit-
ted with complete service kits and fresh oil.
Non-rebuildable units should be replaced.
5 . Rear suspension sticks-This
caused by a bent shock absorber piston rod
(Figure 26). Replace the shock; the rod can't be
6. Steering is tight o r "notchy"-Steering
bearings may be dry, dirty, or worn. Adjust-
ment of the steering head bearing pre-load may
be too tight.
Steering is sloppy-Steering
ment may be too loose. Also check the swing
arm pivot; looseness or extreme wear at this
point translate to the steering.
Brake problems arise from wear, lack of
maintenance, and from sustained or repeated
exposure to dirt and water.
Brakes are ineffective-Ineffective
are most likely caused by incorrect adjustment.
If adjustment will not correct the problem,
remove the wheels and check for worn or glazed
linings. If the linings are worn beyond the ser-
vice limit, replace them. If they are simply
glazed, rough them up with light sandpaper.
In hydraulic brake systems, low fluid levels
can cause a loss of braking effectiveness, as can
worn brake cylinder pistons and bores. Also
check the pads to see if they are worn beyond
the service limit.
2. Brakes lock o r drag-This
may be caused by
incorrect adjustment. Check also for foreign
matter embedded in the lining and for dirty and
dry wheel bearings.
Many electrical system problems can be easi-
ly solved by ensuring that the affected connec-
tions are clean, dry, and tight. In battery equip-
ped motorcycles, a neglected battery is the
source of a great number of difficulties that
could be prevented by simple, regular service to
multimeter, like the volt/ohm/milliam-
meter described in Chapter One, is invaluable
for efficient electrical system troubleshooting.
