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.

@ If you are not familiar with motor-
cycle service, this work should be
done by a Yamaha dealer. @

Tool kitThe tool kit is located inside the right
saddlebag. The tools provided in the
owner’s tool kit are to assist you in the
performance of periodic maintenance.
However, some other tools such as a
torque wrench are also necessary to
perform the maintenance correctly.
The 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.1. Owner’s tool kit

Spark plug inspectionThe spark plug is an important engine
component and should be inspected
periodically, preferably by a Yamaha
dealer. The condition of the spark plug
can indicate the condition of the en-
gine.
Normally, all spark plugs from the
same engine should have the same
color on the white insulator around the
center electrode. The ideal color at this
point is a medium-to-light tan color for a
motorcycle that is being ridden normal-
ly. If one spark plug shows a distinctly
different color, there could be some-
thing wrong with the engine.Do not attempt to diagnose such prob-
lems yourself. Instead, take the motor-
cycle to a Yamaha dealer. The spark
plugs should be periodically removed
and inspected because heat and de-
posits will cause any spark plug to
slowly break down and erode. If elec-
trode erosion becomes excessive, or if
carbon and other deposits are exces-
sive, the spark plug should be replaced
with the specified plug.
Before installing any spark plug, mea-
sure the electrode gap with a wire
thickness gauge and adjust it to specifi-
cation.When installing a spark plug, the gas-
ket surface should always be cleaned
and a new gasket used. Any grime
should be wiped off from the threads
and the spark plug tightened to the
specified torque.
NOTE:@ If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4 to 1/2 turn
past finger tight. The spark plug should
be tightened to the specified torque as
soon as possible. @

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. @

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.

Steering inspectionPeriodically inspect the condition of the
steering. Worn out or loose steering
bearings may be dangerous. Place a
stand under the engine to raise the
front wheel off the ground. Hold the
lower end of the front forks and try to
move them forward and backward. If
any free play can be felt, ask a Yamaha
dealer to inspect and adjust the steer-
ing. Inspection is easier if the front
wheel is removed.

WARNING
@ Securely support the motorcycle so
there is no danger of it falling over. @

BatteryThis motorcycle is equipped with a
sealed-type battery. Therefore it is not
necessary to check the electrolyte or fill
the battery with distilled water.l
If the battery seems to have dis-
charged, consult a Yamaha deal-
er.
l
If the motorcycle is equipped with
optional electrical accessories, the
battery tends to discharge more
quickly, so be sure to recharge it
periodically.

CAUTION:@ Never try to remove the sealing caps
of the battery cells. The battery will
be damaged. @
