Adjustin g the shock a bsorb er
assem blyThis shock absorber assembly is
equipped with a spring preload adjust-
ing nut, a rebound damping force ad-
justing screw and a compression
damping force adjusting screw.NOTICE
ECA10102
To avoi d d amag ing the mechanism,
d o not attempt to turn b eyond the
maximum or minimum setting s.Spring preloa d
Adjust the spring preload as follows. 1. Loosen the locknut.
2. To increase the spring preload and thereby harden the suspen-
sion, turn the adjusting nut in di-
rection (a). To decrease the spring
preload and thereby soften the
suspension, turn the adjusting nut
in direction (b).
A special wrench can be ob-
tained at a Yamaha dealer to
make this adjustment.
The spring preload setting is
determined by measuring
distance A, shown in the illus-
tration. The longer distance A
is, the lower the spring pre-
load; the shorter distance A
is, the higher the spring pre-
load. With each complete
turn of the adjusting nut, dis-
tance A is changed by 1.5
mm (0.06 in). 3. Tighten the locknut to the speci-
fied torque. NOTICE: Always
ti g hten the locknut ag ainst the
a d justin g nut, an d then ti ghten
the locknut to the specified
torque.

eter gent resi due usin g plenty
of water, as it is harmful to plas-
tic parts.
Do not use any harsh chemical
prod ucts on plastic parts. Be
sure to avoi d using cloths or
spon ges which have been in
contact with stron g or a brasive
cleanin g prod ucts, solvent or
thinner, fuel ( gasoline), rust re-
movers or inhi bitors, brake flui d,
antifreeze or electrolyte.
Do not use hi gh-pressure wash-
ers or steam-jet cleaners since
they cause water seepa ge an d
d eterioration in the followin g ar-
eas: seals (of wheel an d swin g-
arm bearin gs, fork an d b rakes),
electric components (couplers,
connectors, an d switches),
b reather hoses an d vents.
After normal useRemove 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 or near the sea
Since sea salt is extremely corrosive,
carry out the following steps after each
ride in the rain or near the sea.
1. Clean the motorcycle with cold water and a mild detergent, after
the engine has cooled down.
NOTICE: Do not use warm wa-
ter since it increases the corro-
sive action of the salt.
[ECA10792]
2. Apply a corrosion protection spray on all metal, including chrome-
and nickel-plated, surfaces to pre-
vent 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 stainless-
steel parts, including the exhaust
system. 4. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal,
including chrome- and nickel-plat-
ed, surfaces.
5. Use spray oil as a universal clean- er to remove any remaining dirt.
6. Touch up minor paint damage caused by stones, etc.
7. Wax all painted surfaces.
8. Let the motorcycle dry completely before storing or covering it.
WARNING
EWA11132
Contaminants on the brakes or tires
can cause loss of control. Make sure that there is no oil or
wax on the brakes or tires.
If necessary, clean the brake
d iscs an d b rake linin gs with a
re gular brake disc cleaner or
acetone, an d wash the tires with
warm water an d a mil d d eter-
g ent. Before ri din g at hi gher
speed s, test the motorcycle’s
b rakin g performance an d cor-
nerin g b ehavior.
