TIPAlthough the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
specifications as necessary.

Adjusting the shock absorber
assembly
WARNING
EWA10210
Always adjust both shock absorber
assemblies equally, otherwise poor
handling and loss of stability may
result.Each shock absorber assembly is
equipped with a spring preload adjust-
ing ring and rebound and compression
damping force adjusting knobs.
Spring preload
Adjust the spring preload as follows.
1. Loosen the lock screw 1/2 turn
counterclockwise.2. To increase the spring preload and
thereby harden the suspension,
turn the adjusting ring in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting ring in
direction (b).
Use the special wrench in-
cluded in the owner’s tool kit
to make this adjustment.
The spring preload setting is
determined by measuring dis-
tance A, shown in the illustra-
tion. The longer distance A is,
the higher the spring preload;
the shorter distance A is, the
lower the spring preload. With
each complete turn of the ad-
justing ring, distance A chang-
es by 1.5 mm (0.06 in).
Be sure to turn the adjusting
ring so that the lock screw is
facing outward.

33. Tighten the lock screw to the spec-
ified torque.
Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting knob in direction(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting knob in di-
rection (b).
Compression damping force
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting knob

soften the compression damping, turn
the adjusting knob in direction (b).
NOTICE
ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.TIPTo obtain a precise adjustment, it is ad-
visable to check the actual total number
of clicks or turns of each damping force
adjusting mechanism. This adjustment
range may not exactly match the spec-
ifications listed due to small differences
in production.
WARNING
EWA10231
These shock absorber assemblies
contain highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assemblies.
Do not tamper with or attempt to
open the cylinder assemblies.
Do not subject the shock ab-
sorber assemblies to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.
Do not deform or damage the
cylinders in any way. Cylinder
damage will result in poor
damping performance.
Do not dispose of a damaged or
worn-out shock absorber as-
sembly yourself. Take the shock
absorber assembly to a Yamaha
dealer for any service.

holders and one retractable luggage
strap holder on each side of the vehicle.

EXUP system This model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that regu-
lates the inner diameter of the exhaust
pipe. The EXUP system valve is con-
stantly adjusted in accordance with the
engine speed by a computer-controlled
servomotor.NOTICE
ECA10191
The EXUP system has been set
and extensively tested at the
Yamaha factory. Changing
these settings without sufficient
technical knowledge may result
in poor performance of or dam-
age to the engine.
If the EXUP system cannot be
heard when the main switch is
turned on, have a Yamaha deal-
er check it.
EAU15303
Sidestand The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.TIPThe built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See page 3-23 for an explanation of
the ignition circuit cut-off system.)
WARNING
EWA10240
The vehicle must not be ridden with
the sidestand down, or if the side-
stand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly as describedbelow and have a Yamaha dealer re-
pair it if it does not function proper-
ly.
