MAINTENANCE WORK ON CHASSIS AND ENGINE

Breather plug front fork

After every 5 hours of use for competitive racing, slacken the breather
plugs [1] a few turns in order to relieve excess pressure from the inside of the
1
fork. To do this, place the motorcycle on a stand with the front wheel lifted
off the ground. When riding the motorcycle mainly on street, it will be enough
to have this job performed in the course of the periodical maintenance
service.
Excessive pressure in the interior of the fork can cause leaks in the fork. If
your fork is leaking, it is recommended to open the breather plugs before hav-
ing the seals replaced.

Cleaning the dust sleeves of the telescopic fork

The dust-protection bellows [2] 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 lever 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 silicone spray. Then, push dust-protection bellows into
the outer tubes by hand.
No silicone 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 to the position that is the most convenient for you. The upper triple
clamp [3] includes 2 bores arranged at a distance of 15 mm (0,6 in) from
one another. The bores at the handlebar support [4] 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 [5] of the handlebar clamps and screws [6]
of the handlebar support. Position handlebar support, and tighten screws [6]
5
to 40 Nm (30 ft.lbs). Mount handlebar and handlebar clamps, and tighten
screws [5] to 20 Nm (15 ft.lbs). The gap between handlebar support and han-
6
dlebar clamps is to be of equal size in the front and in the rear.
The screws [6] must be secured with Loctite 243.
