Next, the air release valves, located in the top oil filler
caps, should be checked by compressing
forks and
observing air pressure release. The fork should return
to its original
position.
If this is not the case, one
must countersink
the seating of the ball (for the air release valve) lightly,
(app. 150°- 160°). The surface
should have no grooves. Otherwise
the ball should be tapped into the seat lightly.
During
re-assembly of
the forks, care must be taken that there is no pressure on the fork tubes or sliders after re-tightening
the
fork pinch bolts and the front
axle.

REAR WHEEL SUSPENSION
The rear wheel suspension
is produced
by a swinging arm which
is attached
to the frame with
rubber
bushings and either Girling or Koni shocks. A properly
functioning
rear suspension gives maximum
perfor-
mance in difficult
terrain.
It is important
to have both shock absorbers adjusted
to produce
the same dam-
pening. The bushings of the swing arms should be checked for play. (Worn bushings MUST be replaced).
A I ight yellow
or brown color on the dampening
rods of the shocks is proof of too much load on the
shock absorbers. The swingarm
bushings should be replaced if necessary. Also, a warped
or bent swing-
arm should be replaced.
Mounting of Koni shock absorbers
1. The retainin9
clips and springs on original
shocks must be removed.
2. The bottom
spring retainer
is put on its lowest setting
(Three different
adjustments
are possible.)
3. The shock rod is extended
completely
and the original
spring is slipped over the shock body oil reser-
voir.
4. The spring is compressed and the retaining
clips are slipped into position.
5. The top and bottom
shock eyes are al igned by rotation
of the top eye
Dampening Adjustment of Koni Shocks
In all Koni ("0"
series) shocks the dampening
is adjustable.
When they are obtained
from
the Koni fac-
tory
they are set on the lowest adjustment,
and can be mounted
immediately.
I f stronger
dampening
is desired, the shocks dampening
can be adjusted.
The spring preload can also be adjusted
to a stronger
setting.
The adjustment
of the shock from extremely
soft to extremely
hard is in 6 different
steps, as
follows:
1. Remove the complete
shock and remove the spring and clips.
2. Extend
the shock rod completely
and push the rubber bumper
to the bottom.
If the bumper
sticks,
pry it loose with a screwdriver.
The retainer
nut (19 mm) is then loosened by securing the top shock
eye with
a screwdriver
or in a vice. The eye, retainer
nut, and rubber bumper
are then removed.
Also
remove the alurnlnum
spacer and do not rB-lnstall it. This will
result in 1/.3

shock travel.
