BLEEDING THE AIR

Dismantling
• Monthly or after every race use a crosshead screwdriver to unscrew the air
bleed screw ( 14 ) in both the fork legs on the top part of the slider, to drain

the pressure that can build up inside.
• Check the state of the oil seal ( 50 ); replace if necessary.
Re- assembly
• Tighten the air bleed screw ( 20 ) to the recommended torque (see Table 1

Munirsi di grasso siliconato spray.
Never use metal tools to clean any particles of dirt.
This operation must be carried out with the fork assembled on the motor-
cycle and with the fork's legs fully extended (front wheel off the ground).
The pressure generated by the air that can get into the fork legs while the
motorcycle is being used and which, due to the special shape of the oil
seals remains trapped inside, can cause the fork to

malfunction.
