Periodic inspection, adjustment
and lubrication will keep your
motorcycle in the safest and most
efficient condition possible. Safety
is an obligation of the motorcycle
owner. The maintenance and lubri-
cation schedule chart should be
considered strictly as a guide to
general maintenance and lubrica-
tion intervals. YOU MUST TAKE
INTO CONSIDERATION THAT
WEATHER, TERRAIN, GEOGRAPHI-
CAL LOCATIONS, AND A VARIETY
OF INDIVIDUAL USES ALL TEND
TO DEMAND THAT EACH OWNER
ALTER THIS TIME SCHEDULE TO
SHORTER INTERVALS TO MATCH
THE ENVIRONMENT. The most
important points of motorcycle
inspection, adjustment, and lubri-
cation are explained in the follow-
ing pages.

If you are not familiar with motor-
cycle service, this work should be

Tool kit
The tool kit is located behind panel
B. (See page 6-7 for panel removal
and installation procedures.) 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 per-
form 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 preventive maintenance
and minor repairs.

Removal
1. Remove the spark plug cap.
2. Use the spark plug wrench in
the tool kit to remove the spark
plug as shown.

Inspection
The spark plug is an important
engine component and is easy to
inspect. The condition of the spark
plug can indicate the condition of
the engine.
The ideal color on the white insula-
tor around the center electrode is a
medium-to-light tan color for a
motorcycle that is being ridden
normally.
Do not attempt to diagnose such
problems yourself. Instead, take
the motorcycle to a Yamaha deal-
er. You should periodically remove
and inspect the spark plug because
heat and deposits will cause any
spark plug to slowly break down
and erode. If electrode erosion
becomes excessive, or if carbon
and other deposits are excessive,
you should replace the spark plug
with the specified plug.
Specified spark plug:

EAU00652Tires
To ensure maximum performance,
long service and safe operation,
note the following:
Tire air pressure
Always check and adjust the tire
pressure before operating the
motorcycle.
EW000082
w
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
according to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc. if
approved for this model), and vehi-
cle speed.
EW000083
w
Proper loading of your motorcycle
is important for several character-
istics 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 motorcy-
cle, and distribute the weight
evenly from side to side. Properly
adjust the suspension for your
load, and check the condition and
pressure of your tires. NEVER
OVERLOAD YOUR MOTORCYCLE.
Make sure the total weight of the
cargo, rider, passenger, and acces-
sories (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.

ger and accessories.

8Operating the motorcycle with
excessively worn tires
decrease riding stability and
can lead to loss of control.
Have excessively worn tires
replaced by a Yamaha dealer
immediately. Brakes, tires, and
related wheel parts replace-
ment should be left to a
Yamaha Service Technician.
8Patching a punctured tube is
not recommended. If it is
absolutely necessary to do so,
use great care and replace the
tube as soon as possible with
a good quality replacement.
EAU00685
Wheels
To ensure maximum performance,
long service, and safe operation,
note the following:
8Always inspect the wheels
before a ride. Check for cracks,
bends or warpage of the
wheel. Be sure the spokes are
tight and undamaged. If any
abnormal condition exists in a
wheel, consult a Yamaha deal-
er. Do not attempt even small
repairs to the wheel. If a wheel
is deformed or cracked, it must
be replaced.
8Tires and wheels should be
balanced whenever either one
is changed or replaced. Failure
to have a wheel balanced can
result in poor performance,
adverse handling characteris-
tics, and shortened tire life.8Ride at moderate speeds after
changing a tire since the tire
surface must first be broken in
for it to develop its optimal
characteristics.

EAU02962Cable inspection and
lubrication
EW000112
w
Damage to the outer housing of
cables may lead to internal rusting
and interfere with the cable move-
ment. Replace damaged cables as
soon as possible to prevent unsafe
conditions.
Lubricate the cables and cable
ends. If a cable does not operate
smoothly, ask a Yamaha dealer to
replace it.EAU00773Throttle cable and grip
lubrication
The throttle twist grip assembly
should be greased at the time that
the cable is lubricated, since the
grip must be removed to get at the
end of the throttle cable. After
removing the screws, hold the end
of the cable up in the air and put in
several drops of lubricant. With the
throttle grip disassembled, coat the
metal surface of the grip assembly
with a suitable all-purpose grease. Recommended lubricant:
Engine oil

EAU00794Steering inspection
Periodically inspect the condition
of the steering. Worn out or loose
steering bearings may be danger-
ous. 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
steering. Inspection is easier if the
front wheel is removed.
EW000115
w
Securely support the motorcycle
so there is no danger of it falling
over.
EAU01144Wheel bearings
If there is play in the front or rear
wheel hub or if the wheel does not
turn smoothly, have a Yamaha
dealer inspect the wheel bearings.
