3To increase the spring preload and
thereby hardening it, turn the ad-
justing bolt in direction (a) from the
standard setting, making sure to
turn the bolt complete turns so that
the alignment marks match.
To decrease the spring preload
and thereby softening it, turn the
adjusting bolt in direction (b) from
the standard setting, making sure
to turn the bolt complete turns so
that the alignment marks match.
TIPDue to small differences in production,
the positions of the alignment marks on
the front fork caps may not exactly
match the illustrations.
Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting bolt on each fork
leg in direction (a). To decrease the re-
bound damping force and thereby soft-
en the rebound damping, turn the
adjusting bolt on each fork leg in direc-
tion (b).Compression damping force
To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting bolt on
each fork leg in direction (a). To de-
crease the compression damping force
and thereby soften the compression
damping, turn the adjusting bolt on
each fork leg in direction (b).

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 This shock absorber assembly is
equipped with a spring preload adjust-
ing nut, a rebound damping force ad-
justing knob and a compression
damping force adjusting screw.NOTICE
ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.Spring preload
Adjust the spring preload as follows.
1. Loosen the locknut.2. To increase the spring preload and
thereby harden the suspension,
turn the adjusting nut in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting nut in
direction (b).


Use the special wrench,
which was handed out sepa-
rately at the purchase of the
vehicle, to make the adjust-
ment.


Attach the extension bar,
which is included in the own-
er's tool kit, to the special
wrench.


The spring preload setting is
determined by measuring dis-
tance A, shown in the illustra-
tion. The longer distance A is,
the lower the spring preload;
the shorter distance A is, the
higher the spring preload.

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-

in production.
WARNING
EWA10221
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.

Do not tamper with or attempt to
open the cylinder assembly.


Do not subject the shock ab-
sorber assembly 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
cylinder 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.

Luggage strap holders There are four luggage strap holders on
the bottom of the seat. To use the strap
holders, remove the seat, unhook the
straps from the hooks, and then install
the seat with the straps hanging out
from under the seat. (See page 3-16.)

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 diameter of the exhaust pipe.
The EXUP system valve is constantly
adjusted in accordance with the engine
speed by a computer-controlled servo-
motor.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.
EAU15301
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 further down 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.

not pulled.


It prevents starting when the trans-
mission is in gear and the clutch le-
