MAINTENANCE WORK ON CHASSIS AND ENGINE

Cleaning the dust sleeves of the telescopic fork
The dust-protection bellows [1] are to remove dust and coarse dirt particles
from the fork tube. However, after some time, dirt may also get in behind the
dust-protection bellows. If this dirt is not removed, the oil sealing rings located
behind it may start to leak.
Use a screwdriver to lift the dust-protection bellows out of the outer tubes
and slide them downward.
Clean the dust-protection bellows, outer tubes, and fork tubes thoroughly, and
oil them thoroughly with Universal oil spray (Motorex Joker 440) or engine
oil. Then, push the dust-protection bellows into the outer tubes by hand.
No oil may reach the front tire or the brake disks since this would consider-
ably reduce the tire's road grip and the braking effect of the front brake.
How to change the handlebar position
The handlebar position can be readjusted by 22 mm. Thus, you can put the
handlebar in the position that is the most convenient for you. The upper triple
clamp [2] includes 2 bores arranged at a distance of 15 mm (0.6 in) from
one another. The bores at the handlebar support [3] are offset from the cen-
ter by 3.5 mm (0.13 in). Accordingly, you can mount the handlebar in 4 dif-
ferent positions.
For this purpose, remove screws [4] of the handlebar clamps and screws [5]
of the handlebar support. Position handlebar support, and tighten screws [5]
to 40 Nm. Mount handlebar and handlebar clamps, and tighten screws [4]
to 20 Nm. The gap between the handlebar support and handlebar clamps
should be the same size in the front and in the rear.
The screws [5] must be secured with loctite 243.

Changing spring preloading of the shock absorber
This is easily done.
NOTE: Before changing the spring preload note down the basic setting, e.g.
how many threads are visible above the adjusting ring.
Loosen the locking ring [6] with the hook spanner. Change the spring
preload with the adjusting ring [7] and re-tighten the locking ring [6].
BASIC SETTING – SPRING PRELOAD: 7 mm (0.28 in)
The damping unit of the shock absorber is filled with high compressed nitro-
gen. Never try to take the shock absorber apart or to do any maintenance work
yourself. Severe injuries could be the result.
