7-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.

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.
EWA00018
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.). @CE-37EEW000083
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. @

7 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.
EW000079
WARNING
@ 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. @

7Tire information
This motorcycle is equipped with tube-
less tires, tire valves and cast wheels.
EW000132
WARNING
@ After extensive tests, the tires men-
tioned below have been approved
by Yamaha Motor Co., Ltd. for this
model. No guarantee for handling
characteristics can be given if tire
combinations other than what is ap-
proved are used on this motorcycle.
The front and rear tires should be of
the same manufacture and design.
Always use the tire valves and valvecores listed below. Be sure to install
the valve caps securely, as these
are important to prevent air pres-
sure leakage.
@CE-41E
CE-42EEAU01230
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.
