6-PERIODIC MAINTENANCE AND MINOR REPAIR
EAU00464
Periodic inspection, adjustment and lu-
brication will keep your motorcycle in
the safest and most efficient condition
possible. Safety is an obligation of the
motorcycle owner. The maintenance
and lubrication schedule chart should
be considered strictly as a guide to
general maintenance and lubrication
intervals. YOU MUST TAKE INTO
CONSIDERATION THAT WEATHER,
TERRAIN, GEOGRAPHICAL LOCA-
TIONS, AND A VARIETY OF INDIVID-
UAL USES ALL TEND TO DEMAND
THAT EACH OWNER ALTER THIS
TIME SCHEDULE TO SHORTER IN-
TERVALS TO MATCH THE ENVI-
RONMENT. The most important points
of motorcycle inspection, adjustment,
and lubrication are explained in the fol-
lowing pages.

Tool kitThe service information included in this
manual is intended to provide you, the
owner, with the necessary information
for completing some of your own pre-
ventive maintenance and minor re-
pairs. The tools provided in the owner’s
tool kit are to assist you in the perfor-
mance of periodic maintenance. How-
ever, some other tools such as a torque
wrench are also necessary to perform
the maintenance correctly.
NOTE:@ If you do not have necessary tools re-
quired during a service operation, take
your motorcycle to a Yamaha dealer for
service. @

Valve clearance adjustmentThe correct valve clearance changes
with use, resulting in improper fuel/air
supply or engine noise. To prevent this,
the valve clearance must be adjusted
regularly. This adjustment however,
should be left to a professional
Yamaha service technician.

TiresTo ensure maximum performance,
long service and safe operation, note
the following:
Tire air pressure
Always check and adjust the tire pres-
sure before operating the motorcycle.
EW000082
WARNING
@ Tire inflation pressure should be
checked and adjusted when the
temperature of the tire equals the
ambient air temperature. Tire infla-
tion pressure must be adjusted ac-
cording to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc. if approved
for this model), and vehicle speed. @

WARNING
@ Proper loading of your motorcycle
is important for several characteris-
tics of your motorcycle, such as
handling, braking, performance and
safety. Do not carry loosely packed
items that can shift. Securely pack
your heaviest items close to the
center of the motorcycle, and dis-
tribute the weight evenly from side
to side. Properly adjust the suspen-
sion for your load, and check the
condition and pressure of your tires.
NEVER OVERLOAD YOUR MOTOR-
CYCLE. Make sure the total weight
of the cargo, rider, passenger, and
accessories (fairing, saddlebags,
etc. if approved for this model) does
not exceed the maximum load of the
motorcycle. Operation of an over-
loaded motorcycle could cause tire
damage, an accident, or even injury. @
Tire inspection
Always check the tires before operating
the motorcycle. If center tread depth
reaches the limit as shown, if the tire
has a nail or glass fragments in it, or if
the side wall is cracked, contact a
Yamaha dealer immediately and have
the tire replaced.
EW000095
WA R N I N G
@ Operating the motorcycle with ex-
cessively worn tires decrease riding
stability and can lead to loss of con-
trol. Have excessively worn tires re-
placed by a Yamaha dealer
immediately. Brakes, tires, and relat-
ed wheel parts replacement should
be left to a Yamaha Service Techni-
cian. @CE-26ENOTE:@ These limits may be different by regula-
tion from country to country. If so, con-
form to the limits specified by the
regulations of your own country. @

This motorcycle is equipped with tube-
less tires, tire valves and cast wheels.
EW000080
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.

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.
@
EAU00687
WheelsTo ensure maximum performance,
long service, and safe operation, note
the following:l
Always inspect the wheels before
a ride. Check for cracks, bends, or
warpage of the wheels. If any ab-
normal condition exists in a wheel,
consult a Yamaha dealer. Do not
attempt even small repairs to the
wheel. If a wheel is deformed or
cracked, it must be replaced.
l
Tires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result
in poor performance, adverse han-
dling characteristics, and short-
ened tire life.
l
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.

WARNING
@ A soft or spongy feeling in the brake
pedal can indicate the presence of
air in the brake system. This air
must be removed by bleeding the
brake system before the motorcycle
is operated. Air in the system will
cause greatly diminished braking
capability and can result in loss of
control and an accident. Have a
Yamaha dealer inspect and bleed
the system if necessary. @

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 ad-
justing 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.1. Brake light switch
