FRAME, SUSPENSIONS AND WHEELS
4- Air bleeding (FIG.23)
NOTE
Perform this operation with legs fully in rebound (front wheel up from the soil), still
fitted in the motorcycle.
PROCEDURE
Every month or after each ride, unscrew the bleeder screw (14) on the top of each
slider, to depressurize the legs. This pressure is produced by the air trapped
inside while riding. Due to the special oil seal shape, the air cannot go out, thus
causing some fork problems.
When finished, tighten the bleeder screws (14).
INSTALLATION
IMPORTANT: the fork should be assembled on the frame in compliance with the
motorcycle Manufacturer’s specifications as far as the steering elements and the
wheel fastening are concerned. An improper assembly can jeopardize both
rider’s safety and life.
- Assemble the stanchion tubes in the lower + upper crown and position them at
the same height.
- Tighten the fastening screws of the stanchion tubes on the lower + upper crown
using a torque of 25 Nm, following the above 1-2-1 procedure.
- Tighten the locking nuts of the wheel pin on the sliders using a torque of 10 Nm,
following the above 1-2-1 procedure.
