MAINTENANCE WORK ON CHASSIS AND ENGINE
»
Check and adjust steering head bearing *
Check steering head bearing for play periodically. To check this put motorcy-
cle on a stand so that the front wheel is off the ground. Now try to move the
fork forward and backward. To adjust, loosen the five pinch
bolts
[1]
of the top triple clamp and turn steering stem bolt
[2]
clockwise until
there is no more play. Don’t tighten the steering stem bolt all the way, other-
wise the bearings will be damaged. With a plastic hammer, lightly tap on the
triple clamp to release tension. Retight the five pinch bolts with
20 Nm.
IF THE STEERING HEAD BEARING IS NOT ADJUSTED TO BE FREE OF PLAY, THE
MOTORCYCLE WILL SHOW AN UNSTEADY DRIVING PERFORMANCE AND CAN GET
OUT OF CONTROL.
IF YOU DRIVE WITH PLAY OF STEERING HEAD BEARING FOR LONGER PERIODS,
FIRST THE BEARINGS AND THEN THE BEARING SEATS IN THE FRAME WILL BE
DESTROYED.
At least once a year, the steering head bearings should be smeared with water-
proof grease (Motorex Long Term 2000).
Breather plug front fork
After every 5 hours of use for competitive racing, slacken the breather
plugs
[3]
a few turns in order to relieve excess pressure from the inside of the
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 serv-
ice.
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 HAVING THE SEALS REPLACED.
Cleaning the dust sleeves of the telescopic fork
The dust-protection bellows
[4]
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 Universal 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.
