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.

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 the cen-
terstand.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-right side of the
crankcase.
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 (with or
without oil filter element replace-
ment)
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.
NOTE:_ Skip steps 4–8 if the oil filter element is
not being replaced. _4. Remove the oil filter element drain
screw to drain the oil from the oil
filter element.
5. Remove the oil filter element cover
by removing the bolt.

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.
l
Make sure that no foreign mate-
rial enters the crankcase.
_11. 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. _12. Turn the engine off, and then
check the oil level and correct it if
necessary. Recommended engine oil:
See page 8-1.

Without oil filter element
replacement:

Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.
l
Be careful that water does not en-
ter the brake or clutch fluid reser-
voir when refilling. Water will
significantly lower the boiling point
of the fluid and may result in vapor
lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU03792
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 brake and clutch master cylin-
ders and caliper as well as the brake
and clutch hoses replaced at the inter-
vals listed below or whenever they are
damaged or leaking.l
Oil seals: Replace every two
years.
l
Brake and clutch hoses: Replace
every four years.

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. _
EAU03209
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. Disconnect the throttle cable, hold
it up, and then apply several drops
of oil to the cable end, allowing it to
trickle into the sheath.
3. Connect the throttle cable, and
then grease the inside of the throt-
tle grip housing.
4. Grease the metal-to-metal contact
surface of the throttle grip, and
then install the grip by installing
the screws. Recommended lubricant:
Engine oil
Recommended lubricant:
Throttle cable:
Engine oil
Throttle grip housing and grip:

Checking and lubricating the
centerstand and sidestand The operation of the centerstand and
sidestand should be checked before
each ride, and the pivots and met-
al-to-metal contact surfaces should be
lubricated if necessary.

WARNING
_ If the centerstand or sidestand does
not move up and down smoothly,
have a Yamaha dealer check or re-
pair it. _

_ Securely support the motorcycle so
that there is no danger of it falling
over. _Check the inner tubes for scratches,
damage and excessive oil leakage.
