GAS GAS EC 125 - 2003 Service Manual page 47

Front fork doesn´t respond to small bumps in sweeping turns:
- Front Fork is too hard:
1. Decrease the compression damping or rebound damping.
2. Decrease oil level 10 mm.
3. Use softer duty spring.
Rear end ¨kicks¨when braking over bumps:
The shock probably has too little rebound damping.
- Increase the rebound damping.
Rear tire won´t "hook up" out of corners:
(A lack of traction coming out of turns)
- The shock may be too stiff:
1. Decrease the rear shock spring preload.
2. Decrease the compression damping.
3. Use softer spring (In case of a lightweight rider).
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. Delantera: Increase oil lever and/or use harder spring.
2. Rear: Increase spring preload and/or increase compression
damping or use harder spring.
NOTE
After any adjustment, check front and rear compatibility.
Adjustment depending on bottoming condition:(rear shock
absorber).
- Bottoms at low speed.
- Increase spring preload until maximum preload is achieved.
- Bottom after successive 3 or 4 successive jumps.
- Decrease rebound damping.
The rear shock on this machine may mislead some riders.
a) The rear shock bottoms when the spring and damping are
overcome by the total weight of the machine and rider (due to 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 end off jumps; if it doesn´t approach bottoming,
try lowering the sping preload and damping.
Gearing
Preconditions:
Course condition
Fast course
Many courves or hills
Sandy or soft groud
- Si la parte recta de la "crono" es larga, el desarrollo puede alargarse
por lo tanto la velocidad aumenta.
