NOTE:_

The air filter needs more frequent service if you are riding in unusually wet or dusty areas.


Hydraulic brake service
•Regularly check and, if necessary, correct the brake fluid level.
•Every two years replace the internal components of the brake master cylinders and calipers, and change the brake
fluid.
•Replace the brake hoses every four years and if cracked or damaged.

Adjusting the brake pedal
position The top of the brake pedal should be
positioned approximately 7–11 mm be-
low the bottom of the footrest bracket
as shown. Periodically check the brake
pedal position and, if necessary, have
a Yamaha dealer adjust it.
EW000109
WARNING
_ A soft or spongy feeling in the brake
pedal can indicate the presence of
air in the hydraulic system. If there
is air in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the motorcycle. Air in
the hydraulic system will diminish
the braking performance, which
may result in loss of control and an
accident. _
EAU00713
Adjusting the rear brake light
switch The rear brake light switch, which is ac-
tivated by the brake pedal, is properly
adjusted when the brake light comes
on just before braking takes effect. If
necessary, adjust the brake light switch
as follows.
Turn the adjusting nut while holding the
rear brake light switch in place. To
make the brake light come on earlier,
turn the adjusting nut in direction
a. To
make the brake light come on later,
turn the adjusting nut in direction
b.

wise the lens may break. @
EAU01579
Supporting the motorcycle Since this model is not equipped with a
centerstand, follow these precautions
when removing the front and rear
wheel or performing other mainte-
nance requiring the motorcycle to
stand upright. Check that the motor-
cycle is in a stable and level position
before starting any maintenance. A
strong wooden box can be placed un-
der the engine for added stability.
To service the front wheel
1. Stabilize the rear of the motorcycle
by using a motorcycle stand or, if
an additional motorcycle stand is
not available, by placing a jack un-
der the frame in front of the rear
wheel.
2. Raise the front wheel off the
ground by using a motorcycle
stand.

MOTORCYCLE CARE AND STORAGE

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, switch-
es 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
compounds for plastic may
leave scratches on the wind-shield. Test the product on a
small hidden part of the wind-
shield to make sure that it does
not leave any marks. If the wind-
shield is scratched, use a quali-
ty plastic polishing compound
after washing.
@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. Use the
special sponge, which is included in the
plastic bag containing the owner’s
manual, to clean the muffler and to re-
move any discoloration from it.After riding in the rain, near the sea or
on 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.NOTE:@ Salt sprayed on roads in the winter may
remain well into spring. @1. Clean the motorcycle with cold
water and a mild detergent, after
the engine has cooled down.
ECA00012
CAUTION:@ Do not use warm water since it in-
creases the corrosive action of the
salt. @2. Apply a corrosion protection spray
on all metal, including chrome-
and nickel-plated, surfaces to pre-
vent corrosion.
