Troubleshooting Improper Settings

 

Listed below are some symptoms of improper suspension settings 
and the most likely means of correcting them. 

The proper settings can be achieved by applying the information in 
this chapter in a scientific manner. Take time to think about the 
changes you believe necessary, check them against the symptoms 
and cures described here, and make the changes in small increments, 
and take notes on the changes and their effects.

Symptoms of the front fork 

- The front fork is too stiff:

1. Incorrect rebound adjustment. 
2. The springs are too hard. 
3. Too much oil.
4. Oil too dense. 

- The fork becomnes hard at the end of travel: 

1. The oil level is too high. 

- The fork operates but slides hard:

1. Oil too dense.
2. Degraded fork oil.

- Too soft:

The fork shakes excessively when slowing down or applying brakes 
1. Fork oil level is low. 
2. Springs are too soft. 
3. Oil too light. 
4. Degraded fork oil.
5. Incorrect rebound or compression.

Symptoms of the rear shock absorber:

- Too hard:

1. The suspension is too stiff

• Compression damping is too high. 
• Spring is too hard.

2. Is hard to ride

• Unbalanced condition between the spring and rebound 
  (too low). 

3. The spring is hard or preloaded too much

- Too soft:

On landing after a big jump, the suspension makes jounce stops.
1. Soft spring or compression damping is too soft. 
2. Degraded shock absorber oil

Determining the proper settings:

- Standard Settings

From the factory, the machine is set up for an average-weight rider 
with average riding abilities. Hence, if the actual rider’s weight or if 
his riding experience and abilities are considerably superior or below 
the average, ii is necessary to make adjustments to the suspension.

- Readjustment of the suspension:

Ground surface

Smooth

soft spring

Rough

hard spring
