Adjustments for Competition 113
Front Suspension Adjustments
Front Suspension Damping
Compression Damping
Adjustment
This adjustment affects how quickly the fork
compresses. The fork compression damping
adjuster (1) has 18 positions or more. Turning the
adjuster screw one full turn changes the adjuster
four positions. To adjust the compression
damping to the standard position, proceed as
follows:
Turn the adjuster clockwise until it will no longer
turn (lightly seats). This is the full hard position.
The adjuster is set in the standard position when
the adjuster is turned counterclockwise 12 clicks.
Make sure that both fork legs are adjusted to the
same position.
Rebound Damping
Adjustment
The fork rebound damping adjuster (2) has 16
positions or more. Turning the adjuster screw one
full turn clockwise advances the adjuster four
positions. To adjust the rebound damping to the
standard setting, proceed as follows:
Turn the adjuster clockwise until it will no longer
turn (lightly seats). This is the full hard position.
The adjuster is set in the standard position when
the adjuster is turned counterclockwise 8 clicks.
Make sure that both fork legs are adjusted to the
same position.
Both compression and rebound damping can be
increased by turning the adjuster clockwise.
Always start with full hard when adjusting
damping.
Do not turn the adjuster screw more than the
given positions or the adjuster may be damaged.
Be sure that the compression and rebound
adjusters are firmly located in a detent, and not
between positions.
NOTICE
Fork Springs
The fork springs in CRFs are about right for
riders weighing between 150 lb (68 kg) and 160
lb (73 kg) (less riding gear). So if you're a
heavier rider, you have to go up on the oil
capacity or get a stiffer spring. Do not use less oil
than the minimum specified for each spring or
there will be a loss of rebound damping control
near full extension. If the fork is too hard on big
bumps, turn the damping adjuster
counterclockwise 1-turn and lower the oil
capacity in increments of 0.2 US oz (5 cm
3
) in
both fork legs until the desired performance is
obtained. Do not, however, lower the oil capacity
below the minimum oil capacity.
Minimum oil capacity:
Standard spring:
10.3 US oz (305 cm
3
)
Softer spring: 10.2 US oz (303 cm
3
)
Stiffer spring: 10.1 US oz (300 cm
3
)
When adjusting oil capacity, bear in mind that
the air in the fork will increase in pressure while
riding; therefore, the higher the oil capacity, the
higher the eventual pressure of any air in the
fork.
