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 dust-protection bellows, outer tubes, and fork tubes thoroughly, and oil
them thoroughly with oil-spray (Motorex Joker 440) or engine oil. Then, push
dust-protection bellows into the outer tubes by hand.
NO OIL MAY REACH THE FRONT TIRE OR THE BRAKE DISKS SINCE THIS WOULD
CONSIDERABLY 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
center by 3.5 mm (0.13 in). Accordingly, you can mount the handlebar in
4 different 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 the spring preloading of the shock absorber
The spring preload can be changed by turning the adjusting ring [6]. For this
purpose, you should dismount the shock absorber and clean it thoroughly.
NOTE:
– Before changing the spring preload note down the basic setting, e.g. how
many threads are visible above the adjusting ring.
– One rotation of the adjusting ring [6] changes the spring pretension by
approximately 1.75 mm (0.07 in).
Loosen the clamping screw [7] and use the hook wrench contained in the
vehicle tool set to turn the adjusting ring as desired. Turning it counterclock-
wise will reduce the preload, turning it clockwise will increase the
preload. After readjusting the clamping screw [7], tighten it to 8 Nm (6 ft.lb).
