6To 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. Place the spark plug cover in the
original position.

Engine oil and oil filter 
element The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result in
a false reading. @2. Start the engine, warm it up for
several minutes, and then turn it
off.

tles, and then check the oil level
through the check window located
at the bottom-left side of the crank-
case.
NOTE:@ The engine oil should be between the
minimum and maximum level marks.@4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.To change the engine oil without oil
filter element replacement
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.4. Install the engine oil drain bolt, and
then tighten it to the specified
torque.
5. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler

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 ad-
dition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
l
Make sure that no foreign mate-
rial enters the crankcase. 
@
6. 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. @
EC000067
CAUTION:@ If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha deal-
er check the vehicle. @7. Turn the engine off, and then
check the oil level and correct it if
necessary.NOTE:@ Have a Yamaha dealer replace the oil
filter element when necessary. @
EAU02943*
Final gear oil The final gear case must be checked
for oil leakage before each ride. If any
leakage is found, have a Yamaha deal-
er check and repair the motorcycle. In
addition, the final gear oil level must be
checked and the oil changed as follows
at the intervals specified in the periodic
maintenance and lubrication chart.

Make sure that no foreign mate-
rial enters the final gear case.

6 To check the final gear oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.
NOTE:@ l
The final gear oil level must be
checked on a cold engine. 
l
Make sure that the motorcycle is
positioned straight up when check-
ing the oil level. A slight tilt to the
side can result in a false reading. 
@2. Remove the oil filler bolt, and then
check the oil level in the final gear
case.
NOTE:@ The oil level should be at the brim of
the filler hole. @3. If the oil is below the brim of the fill-
er hole, add sufficient oil of the rec-
ommended type to raise it to the
correct level.
To change the final gear oil
1. Place an oil pan under the final
gear case to collect the used oil.
2. Remove the oil filler bolt and drain
bolt to drain the oil from the final
gear case.
3. Install the final gear oil drain bolt,
and then tighten it to the specified
torque.
4. Add the recommended final gear
oil to the brim of the filler hole.
NOTE:@ GL4 is a quality rating. Hypoid gear oils
rated GL5 or GL6 may also be used. @5. Install and tighten the filler bolt to
the specified torque.
6. Check the final gear case for oil
leakage. If oil is leaking, check for
the cause.

Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil seals
of the master cylinder and caliper as
well as the brake hoses replaced at the
intervals listed below or whenever they
are damaged or leaking.l
Oil seals: Replace every two
years.
l
Brake hoses: Replace every four
years. 
EAU02962
Checking and lubricating the 
cables The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
EW000112
WARNING
@ Damage to the outer sheath may in-
terfere with proper cable operation
and will cause the inner cable to
rust. Replace a damaged cable as
soon as possible to prevent unsafe
conditions. @
EAU03764
Checking and lubricating the 
throttle grip and cable The operation of the throttle grip and
the condition of the throttle cable
should be checked before each ride,
and the cable should be lubricated or
replaced if necessary.NOTE:_ Since the throttle grip must be removed
to access the throttle cable end, the
throttle grip and the cable should al-
ways be lubricated at the same time. _1. Remove the throttle grip by remov-
ing the screws.
2. Hold up the throttle cable, and
then apply several drops of oil to
the cable, allowing it to trickle into
the sheaths.
3. Grease the inside of the throttle
grip housing. Recommended lubricant:
Engine oil
