Introduction
No area of machine adjustment is more critical than proper suspension tuning. An improperly tuned suspension will keep even the best rider from attaining the full benefit of his machine’s ability. Match the suspension to the rider and the course conditions.
WHILE TUNING THE SUSPENSION, KEEP THE FOLLOWING IMPORTANT POINTS IN MIND:
Front Fork Oil Level
Fork Oil Level Effect on Fork Stroke
Changing the fork oil level works effectively at the end of fork travel. If fork bottoming is experienced, raise the fork oil level. This will change the secondary spring rate.
Fork Oil Level Adjustment
Adjust the fork oil level (see Front Suspension section).
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 given in this chapter in a scientific, methodical manner. This does not mean, however, that you must be a scientist or trained technician to succeed. Simply take time to think about the changes you believe are necessary, check them against the symptoms and cures described here, make the changes in small increments, and take note of the changes and their effects.
Too Hard Spring too stiff:
Too Soft The front fork dives excessively during braking and deceleration
Too Hard Suspension too stiff:
Compression damping too high
Spring too hard
Rebound damping too high
Spring preload too hard
Too Soft Bottoming occurs on landing after a high jump (otherwise OK):
Spring preload too soft or compression damping too soft
Spring too soft
Shock absorber oil deteriorated
Standard Settings
From the factory, the machine is set up for a medium-weight rider with intermediate riding ability. Hence, if the actual rider weighs considerably more or less, or if his riding experience and ability are much above or below the intermediate level, it is likely that a few basic suspension adjustments will be necessary.
Suspension Tuning According to Ground Surface
Suspension Tuning According to the Type of Course
Begin the actual on-track testing and evaluation after making these preliminary adjustments. Bear in mind the following points when readjusting the suspension.
Front and Rear Suspension Inspection
Use this procedure to determine if the suspension is balanced reasonably well.
Although this is one of the most effective adjustment procedures, suspension settings may vary depending on the conditions at the track and the rider’s preferences.
Front End Surges Downhill or During Acceleration Out of Corner
The front suspension is too soft.
Front End “Knifes” or Oversteers in Turns (Tends to Turn Inward)
NOTE
Heavieror expert riders may need a harder spring.
Front End Pushes or “Washes Out” in Turns (Front Wheel Tends to Push Outward Rather than “Bite” in a Turn)-
The front suspension is too stiff.
NOTE
Lighter or less experienced riders may need a softer spring.
Front End Does Not Respond to Small Bumps in Sweeping Turns
The front suspension is too hard.
Rear End “Kicks” When Braking on Bumps
Rear Tire Does Not “Hook Up” Out of Corners (Lack of Traction Coming Out of Turns)
The rear shock absorber may be too stiff.
Front and Rear Ends Bottom Off After a High-speed Jump (harsh bottoming occurs once or twice per lap)
The front suspension is too soft.
The rear suspension is too soft.
NOTE
Check the front and rear suspension compatibility after making any adjustment.
Rear End Feels Soft on Bumps
Rear End Bottoms After 3 or 4 Successive Jumps
