For YZF-R1
This model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, fast compres-
sion damping force, and slow
compression damping force can be
adjusted.NOTICE

1. Loosen the locknut.
2. Turn the adjusting nut in direction (a) to increase the spring preload.
Turn the adjusting nut in direction
(b) to decrease the spring preload.
The spring preload setting is de-
termined by measuring distance
A. The longer distance A is, the
higher the spring preload; the
shorter distance A is, the lower the
spring preload. Use the special wrench in-
cluded in the tool kit to make
the adjustment.

adjuster in direction (b), it may
click beyond the stated specifica- tions, however such adjustments
are ineffective and may damage
the suspension.

7 Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification.
Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the spark
plug threads.
NOTICE
ECA10841
Do not use any tools to remove or in-
stall the spark plu
g cap, otherwise
the i gnition coil coupler may get
d amag ed . The spark plu g cap may
b e difficult to remove because the
ru bber seal on the en d of the cap fits
ti g htly. To remove the spark plu g
cap, simply twist it b ack and forth
while pullin g it out; to install it, twist
it back an d forth while pushin g it in.
