REAR SUSPENSION
The swinging fork pivots on bronze bushes w hi ch shou ld be lubricated
with a high p
re ssure grease gun at least every 1,000 mi les (1,600Km)
until grease is seen to exude from the ends of the pivot s.
There are two nipples, one beneath each bearing housing. If the mileage
intervals are not conven
ie nt, it is better to grease more frequently rather
th an to extend the interv al. The movement is controlled by Gi rl in g gas
pressurised mono tube damper units. The hydrau
li c damping mecha ni sm
is completely sealed but the static loading of the spring is adjus
ta ble.
There is a three
pOSition castellated cam ring covered by a shroud be low

" C" spanner is provided in the to olkit.

stand so
th at the re is least load on the spring and use the "C" spanner to
turn the
ca m; both units must be on th e same notch wh i ch ever may be
chosen.
A quick visual check can be made on this paint from the rear of
th e
machine as
in Fig. 7. Comparing the exposed lengt hs of the units wi ll
establish that the loading is equal. To increase the static loading. tu rn the
castellated cam ring
in the direction shown.
The standard lowest position is
for solo riding, the second position is for
heavier solo riders or when luggage
is carried on the rear of the machine
