NOTE:_ The spring preload setting is deter-
mined by measuring distance A, shown
in the illustration. The shorter distance
A is, the lower the spring preload; the
longer distance A is, the higher the
spring preload. _

EAU00464
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 owner’s tool kit is located inside
the storage compartment under the
seat. (See page 3-11 for 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 cowling.

68. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil tank
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.
@9. 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.
10. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU03495
Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
If the engine overheats, see page 6-45
for further instructions.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:@ l
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
l
Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.
