Does the front fork fails to respond to small potholes while
managing wide turns?
Front Fork is hard:
1. Decrease the compression or rebound damping.
2. Decrease the oil level 10 mm.
3. Use softer duty spring.
Does the rear end jumps when braking over potholes?:
The shock absorber probably has too little rebound damping.
- Increase the rebound damping.
Does the rear tire lacks traction when coming out of corners?:
- The shock absorber is too hard:
1. Decrease the rear shock absorber spring.
2. Decrease the compression damping.
3. Use a softer spring.
Does it land on the front wheel in high speed jumps?:
(there may be a problem with the driver's posture)
Rebound damping too soft or hard spring.
1. Increase the rebound damping.
2. Decrease the shock absorber spring preload.
3. Decrease the compression damping.
Does the suspension jounce stops at front and rear of the
motorcycle in high speed jumps?:
(If this occurs 1 or 2 times in the same lap of the race)
Front and rear suspension system are too soft:
1. Front: Increase the oil lever and / or use a harder spring.
2. Rear: Increase compression damping or use a harder spring.
NOTE
After any adjustment, check front and rear compatibility.

Adjustments that depend on the conditions of the jounce stops
(rear shock absorber).
- Suspension jounce stops at low speed, increase the spring preload
to the maximum setting.
- Jounce stops after 3 or 4 successive jumps, decrease the rebound
damping.
The rear shock absorber due to its setting possibilities may
mislead some riders.
a) The rear shock absorber does not jounce stop when the spring
is correct for the total weight of the machine and rider.
b) A jounce stop sensation of the shock absorber may be caused
by the rider's inexperience in riding a machine with a harder
spring.
Observe the rear end while it jumps; if it does not approach the
stopper, try lowering the sping preload.
Gearshift
Select the ratio development. Preconditions:
Race conditions: vary the transmission replacing the rear pinion.
Fast race: use pinions with less teeths.
Winding road or soft or sandy uphill surface: use pinions with more
teeths.
- If the straight portion of the course is long, the ratio development
can be extended and due to this the speed increases.
- When the course has many corners or uphills or is wet, the ratio
development will be reduced so that gear shifting is possible at
low speed.
