CAUTION
Never forget the key in the lock. If you turn left the steering with the
key in, it will be damaged.
FRONT FORK
The front fork should always be adjusted for the rider´s weight and
track conditions by using one or more of the following methods.
- Air pressure: Air pressure acts as a progressive spring and affects
the entire range of fork travel. The air pressure in the fork increases
as the fork heats up, so the fork action on your GAS GAS will get
stiffer as the race progresses. Because of this, we don´t recommend
using air pressure for additional springing. Your GAS GAS forks are
designed to work without adding any air.
- Rebound and compression dampening adjustment: This adjustment
affects how quickly the rebound. The fork rebound dampening
adjuster has 16 clicks. The seated position (fully clockwise until the
adjuster stops) is full hard. From the point 6 - 8 clicks counterclockwise
is the standar setting, and 16 clicks counterclockwise is full soft.
- Oil level adjustment: The effects of higher or lower fork oil level
are only felt during the final 100 mm of fork travel. A higher oil level
will make the fork rebound more slowly.
- Fork springs: Optional springs are available that are softer and
stiffer than standard.
Air Pressure
The standard air pressure in the front fork legs is atmospheric
pressure. The air pressure in the fork legs increases as operation
progresses.
EC FSE 2003 -34-
- Using the stand under the frame, stabilize the motorcycle.
- Place a stand or block under the engine so that the front wheel is
raised off the ground.
- Remove the screws at the top of the front fork top bolts to let the
air pressure equalize. Then replace them.
