WARNING
@ l
After extensive tests, the tires
mentioned below have been ap-
proved by Yamaha Motor Co.,
Ltd. for this model. No guaran-
tee for handling characteristics
can be given if tire combina-
tions other than what is ap-
proved are used on this
motorcycle. The front and rear
tires should be of the same
manufacture and design.
l
The use of tire valves and valve
cores other than listed below
could cause tire deflation dur-
ing extreme high speed riding.
Always use genuine parts or
their equivalent for replace-
ment.
l
Be sure to install the valve caps
securely, as these are important
to prevent air pressure leakage
during extreme high speed
riding.

CE-12EEAU00684
WARNING
@ This motorcycle is fitted with super
high-speed running tires. The fol-
lowing points must be observed in
order for you to make fully effective
use of these tires.l
Never fail to use the specified
tires in tire replacement. Other
tires may have a danger of
bursting at super high-speeds.
l
New tires have a relatively low
grip on the road surface until
they have been slightly worn.
Therefore, approximately 100 km
should be traveled at normal
speed before any high-speed
riding is done.
l
Before any high-speed runs, the
tires should be warmed-up suf-
ficiently.
l
Always inflate to the correct tire
pressure according to the oper-
ating conditions.

Brake light switch adjustmentThe rear brake light switch is activated
by the brake pedal and is properly ad-
justed when the brake light comes on
just before braking takes effect. To ad-
just the rear brake light switch, hold the
switch body so it does not rotate while
turning the adjusting nut.
Turn the adjusting nut in direction
a to
make the brake light come on earlier.
Turn the adjusting nut in direction
b to
make the brake light come on later.

Checking the front and rear
brake padsWear indicator grooves are provided
on each brake pad. These indicators
allow checking of brake pad wear with-
out disassembling the brake. Inspect
the grooves. If they have almost disap-
peared, ask a Yamaha dealer to re-
place the pads.

6Battery storage
When the motorcycle is not used for a
month or longer, remove the battery,
fully charge it and store it in a cool, dry
place.
EC000102
CAUTION:@ l
Completely recharge the bat-
tery before storing. Storing a
discharged battery can cause
permanent battery damage.
l
Use a battery charger designed
for a sealed-type (MF) battery.
Using a conventional battery
charger will cause battery dam-
age. If you do not have a sealed-
type battery charger, contact
your Yamaha dealer.
l
Always make sure the connec-
tions are correct when reinstall-
ing the battery.

Fuse replacementThe fuse boxes are located behind
cowling B. (See page 6-6 for removal
and installation procedures.)
If any fuse is blown, turn off the ignition
switch and the switch of the circuit in
question. Install a new fuse of proper
amperage. Turn on the switches and
see if the electrical device operates. If
the fuse immediately blows again, con-
sult a Yamaha dealer.
EC000103
CAUTION:@ Do not use fuses of higher amper-
age rating than those recommend-
ed. Substitution of a fuse of
improper rating can cause extensive
electrical system damage and pos-
sibly a fire. @

CAUTION:@ Avoid touching the glass part of a
bulb. Keep it free from oil; other-
wise, the transparency of the glass,
life of the bulb, and luminous flux
will be adversely affected. If oil gets
on a bulb, thoroughly clean it with a
cloth moistened with alcohol or lac-
quer thinner. @
4. Install the bulb holder cover and
the headlight connector.
If a headlight beam adjustment is
necessary, ask a Yamaha dealer
to make adjustment.

Rear wheel installation1. Apply a light coating of lithium
soap base grease to the final gear
case splines and the rear wheel
hub splines.
2. Install the wheel and the wheel ax-
le.
3. Install the caliper and caliper bolts.
Make sure there is enough gap
between the brake pads before in-
stalling the caliper onto the brake
disc.4. Install the brake torque rod bolt
and nut.
5. Install the pinch bolt and tighten it
to the specified torque.
6. Take the motorcycle off the cen-
terstand.
7. Tighten the axle nut, caliper bolts
and brake torque rod nut to the
specified torques.
8. Secure the brake torque rod nut
with a new cotter pin.

TroubleshootingAlthough Yamaha motorcycles receive
a rigid inspection before shipment from
the factory, trouble may occur during
operation.
Any problem in the fuel, compression,
or ignition systems can cause poor
starting and loss of power. The trouble-
shooting chart describes a quick, easy
procedure for making checks.
If your motorcycle requires any repair,
bring it to a Yamaha dealer. The skilled
technicians at a Yamaha dealership
have the tools, experience, and know-
how to properly service your motor-
cycle. Use only genuine Yamaha parts
on your motorcycle. Imitation parts may
look like Yamaha parts, but they are of-
ten inferior. Consequently, they have a
shorter service life and can lead to ex-
pensive repair bills.

CAUTION:@ l
Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If you do use such
products for hard-to-remove
dirt, do not leave it on any long-
er than instructed, then thor-
oughly rinse it off with water,
immediately dry the area and
apply a corrosion protection
spray.
l
Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent and
water to clean plastic.
l
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.
l
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 bearings,
swingarm bearings, forks and
brakes), electric components
(couplers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
l
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 they do not
leave any marks. If the wind-
shield is scratched, use a quali-
ty plastic polishing compound
after washing.
@After riding in the rain, near the sea oron salt-sprayed roadsSince sea salt or salt sprayed on the
roads in the winter are extremely corro-
sive in combination with water, carry
out the following steps after each ride
in the rain, near the sea or on salt-
sprayed roads. (Salt sprayed in the
winter may remain on the roads well
into spring.)
