ADJUSTING THE COMPRESSION FORK
a) COMPRESSION (lOWER REGISTER)
Standard calibration: -10 clicks .
Remove plug (B) and turn register (A) clockwise until the posi-
tion of fully closed is reached then, turn back by the mentioned
clicks.To obtain a smoother braking action, turn the register
anticlockwise. Reverse the operation in order to obtain a harder
action.
b) EXTENSION (upper register)
Standard calibration: - 10 clicks.
To reset standard calibration turn register (C) clockwise to reach
the position of fully closed; then, turn back by the mentioned
clicks. To obtain a smoother braking action, turn the register
anticlockwise. Reverse the operation in order to obtain a harder
action.
c) AIR VENT (to carry out after each competition, or monthly).
Set the motorcycle on a central stand and release the fork fully
and loosen the air vent valve (D). Once this operation is over,
tighten the valve.
WARNING: Never force the adjusting screws
beyond the maximum opening and closure
positions.
OIL FORK LEVEL
For the regular fork operation, both legs must be provided with
the necessary oil quantity. Remove the forkrods form the fork to
check the oil level inside the forkrods. Work as follows:
- remove the power rod caps;
- remove springs from the stems letting the oil drop into the
latter;
- bring forks to stroke end;
- check that the level is at distance “A” below the upper limit of
rods.
