Adjusting rebound damping of shock absorber
By using the adjusting screw [1], the degree of damping of the rebound can be adjusted.
Turn the knob in a clockwise direction to increase damping, turn it in a counterclockwise
direction to reduce damping during rebounding.
STANDARD ADJUSTMENT:
– Turn adjusting screw clockwise as far as it will go.
– Turn 15 clicks in a counterclockwise direction.
The damping unit of the shock absorber is filled with high-compression nitrogen. Never try
to take the shock absorber apart or to do any maintenance work yourself. Severe injuries
could be the result.
Breathing the fork legs
Breath the fork legs regularly (see Maintenance Schedule).
To breath, place the motorcycle on the side stand and briefly remove the bleeder screws [2]
to allow any overpressure to escape from the fork.
Excessive pressure in the interior of the fork can cause leaks in the fork. If your fork is leak-
ing, it is recommended to open the breather plugs before having the seals replaced.
