Safety is an obligation of the owner.
Periodic inspection, adjustment and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. The most important points of in-
spection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, DEPENDING ON THE
WEATHER, TERRAIN, GEOGRAPHI-
CAL LOCATION, AND INDIVIDUAL
USE, THE MAINTENANCE INTER-
VALS MAY NEED TO BE SHORT-
ENED.

WARNING
_ If you are not familiar with motor-
cycle maintenance work, have a
Yamaha dealer do it for you. _

Owner’s tool kit The tool kit is located under the pas-
senger seat. (See page 3-11 for pas-
senger seat removal procedures.)
The service information included in this
manual and the tools provided in the
owner’s tool kit are intended to assist
you in the performance of preventive
maintenance and minor repairs. How-
ever, additional tools such as a torque
wrench may be necessary to perform
certain maintenance work correctly.
NOTE:_ If you do not have the tools or experi-
ence required for a particular job, have
a Yamaha dealer perform it for you. _
EW000063
WARNING
_ Modifications not approved by
Yamaha may cause loss of perfor-
mance and render the vehicle un-
safe for use. Consult a Yamaha
dealer before attempting any chang-
es. _

6 To install a spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then tight-
en it 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 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible. _4. Install the spark plug cap.
5. Install the cowlings.

67. Install the new oil filter cartridge,
and then tighten it to the specified
torque with a torque wrench.
8. Install the engine oil drain bolt, and
then tighten it to the specified
torque.9. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.
EC000072
CAUTION:_ l
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives with
the oil or use oils of a higher
grade than “CD”. In addition, do
not use oils labeled “ENERGY
CONSERVING II” or higher.
l
Make sure that no foreign mate-
rial enters the crankcase.
_10. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.NOTE:_ After the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient. _

NOTE:_ Using the alignment marks on each
side of the swingarm, make sure that
both chain pullers are in the same posi-
tion for proper wheel alignment. _
EC000096
CAUTION:_ Improper drive chain slack will over-
load the engine as well as other vital
parts of the motorcycle and can lead
to chain slippage or breakage. To
prevent this from occurring, keep
the drive chain slack within the
specified limits. _3. Tighten the locknuts, and then
tighten the axle nut to the specified
torque.
EAU03006
Lubricating the drive chain The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly wear
out, especially when riding in dusty or
wet areas. Service the drive chain as
follows.
EC000097
CAUTION:_ The drive chain must be lubricated
after washing the motorcycle or
riding in the rain. _1. Clean the drive chain with kero-
sene and a small soft brush.
ECA00053
CAUTION:_ To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate solvents. _2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
ECA00052
CAUTION:_ Do not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings. _

To install the front wheel
1. Install the speedometer gear unit
into the wheel hub so that the pro-
jections mesh with the slots.
2. Lift the wheel up between the fork
legs.NOTE:_ Make sure that the slot in the speedom-
eter gear unit fits over the retainer on
the fork leg. _3. Insert the wheel axle.
4. Lower the front wheel so that it is
on the ground.5. Install the brake calipers by install-
ing the bolts.
NOTE:_ Make sure that there is enough space
between the brake pads before install-
ing the brake calipers onto the brake
discs. _6. Tighten the wheel axle, then the
front wheel axle pinch bolt and the
brake caliper bolts to the specified
torques.
7. Connect the speedometer cable.
8. Install the front fender by installing
the bolts.
9. Push down hard on the handlebar
several times to check for proper
fork operation.

Troubleshooting Although Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills. Tightening torques:
Axle nut:
150 Nm (15.0 m·kg)
Brake caliper bolt:
40 Nm (4.0 m·kg)
