Adjusting the shock absorber
assemblyThis shock absorber assembly is
equipped with a spring preload adjust-
ing ring, a rebound damping force ad-
justing screw, a compression damping
force adjusting bolt (for fast compres-
sion damping) and a compression
damping force adjusting screw (for
slow compression damping).NOTICE
ECA10102
To avoid damaging the mechanism,
do not attempt to turn beyond themaximum or minimum settings.
Spring preload
Spring preload adjustment should be
made by a Yamaha dealer, since this
service requires special tools and tech-
nical skills. The specified settings are
listed below.
The spring preload setting is deter-
mined by measuring distance A, shown
in the illustration. The shorter the dis-
tance A is, the higher the spring pre-
load; the longer distance A is, the lower the spring preload.
Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting screw in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting screw in di-
rection (b).

Minimum (soft):
Distance A = 238.5 mm (9.39 in)
Standard: Distance A = 222 mm (8.74 in)
Maximum (hard): Distance A = 222 mm (8.74 in)

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
EWA10222
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.
EAU15306
SidestandThe 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 the following section for an expla-
nation of the ignition circuit cut-off sys-tem.)
WARNING
EWA10242
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand 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 and have a

12 off any detergent residue using
plenty of water, as it is harmful
to plastic parts.

Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust re-
movers or inhibitors, brake flu-
id, antifreeze or electrolyte.

Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel and swing-
arm bearings, fork and brakes),
electric components (couplers,
connectors, instruments,
switches and lights), breather
hoses and vents.

For motorcycles equipped with
a windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning com-
pounds for plastic may leave
scratches on the windshield. Test the product on a small hid-
den part of the windshield to
make sure that it does not leave
any marks. If the windshield is
scratched, use a quality plastic
polishing compound after
washing.
After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.
After riding in the rain, near the sea oron salt-sprayed roadsSince sea salt or salt sprayed on roads
during winter are extremely corrosive in
combination with water, carry out the
following steps after each ride in the
rain, near the sea or on salt-sprayed
roads.TIPSalt sprayed on roads in the winter may
remain well into spring. 1. Clean the motorcycle with cold wa- ter and a mild detergent, after the
engine has cooled down.
NOTICE: Do not use warm water
since it increases the corrosive
action of the salt.
[ECA10792]
2. Apply a corrosion protection spray on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.
After cleaning 1. Dry the motorcycle with a chamois or an absorbing cloth.
2. Immediately dry the drive chain and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine chrome, aluminum and stain-
less-steel parts, including the ex-
haust system. (Even the thermally
induced discoloring of stain-
less-steel exhaust systems can be
removed through polishing.)
4. To prevent corrosion, it is recom- mended to apply a corrosion pro-
tection spray on all metal,
