GAS GAS FSR 450 2008 Betriebsanleitung Seite 122

Front fork doesn't respond to small potholes in wide turns
- Front fork hard:
1. Decrease the compression damping or rebound damping.
2. Reduce the oil level 10 mm.
3. Use a soft spring.
Rear end kicks when braking on potholes
The shock probably has too little rebound damping.
- Increase the rebound damping.
Rear tire won't "hook up" out of corners
(A loss of traction coming out of turns).
- The shock is too stiff:
1. Reduce rear shock absorber spring.
2. Reduce compression.
3. Use a softer spring.
Landing on front wheel in fast jumps
(could also be a rider position problem).
- Rebound too soft or spring too hard:
1. Increase rebound.
2. Reduce preload of the shock spring.
3. Reduce compression.
Front and rear of the bike bottom off high speed jumps:
(If harsh bottoming occurs once or twice per lap of the race).
. Front and rear suspension system are too soft:
1. Front : Increase oil level and/or use harder spring.
2. Rear: Use a stronger spring and / or increase compression.
NOTE
After any adjustment, check front and rear compatibility.
Adjustments depending on the bottoming of the suspension
(rear shock).
- Bottoms at low speed: Increase spring preload to maximum.
- Bottom after successive 3 or 4 successive jumps.
The rear shock on this machine, due to its adjustment
possibilities, could confuse some riders.
a) The rear shock does not bottom out when the spring and
damping are correct for the total weight of the machine and rider
(full stroke).
b) A bottoming sensation (even through the machine is not bottoming)
may actually be the inability of rider and machine weight to overcome
an overly stiff spring or excessive damping.
Observe the rear while jumping; if it does not approach the limit then
attempt to lower the spring preload.
Gears
Selecting the development. Preconditions.
Track conditions: vary the transmission by changing the rear sprocket.
Fast track: Sprocket with lower number of teeth.
Bends or sandy/soft hills: sprocket with more teeth.
- If the time trial is long then the development may be longer for
increased speed.
- When the time trial of the course has many curves, hills or is wet,
the development is decreased so that gear shifting is possible at low
speeds.
-As a result gears can be changed depending on the terrain on the
day of the race. Ensure to correctly adjust the machine in order to
run the entire race.
