Engine oil and oil filter car-
tridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.NOTE:
Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in afalse reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil set-
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 theminimum 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 cartridge replace-
ment)
1. Place the vehicle on a level sur-
face.2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Place an oil pan under the engine
to collect the used oil.
4. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.
NOTE:Skip steps 5–7 if the oil filter cartridge isnot being replaced.
5. Remove the oil filter cartridge with
an oil filter wrench.

NOTE:An oil filter wrench is available at aYamaha dealer.
6. Apply a thin coat of engine oil to
the O-ring of the new oil filter car-
tridge.
NOTE:
Make sure that the O-ring is properlyseated.
7. Install the new oil filter cartridge
with an oil filter wrench, 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. Refill with the specified amount of
the recommended engine oil, and
then install and tighten the oil filler
cap.

NOTE:Be sure to wipe off spilled oil on any
parts after the engine and exhaust sys-tem have cooled down.CAUTION:
ECA11620
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
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, im-
mediately 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 theoil level is sufficient.CAUTION:
ECA10400
If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha dealercheck the vehicle.
11. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU20070
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.
EAU39084
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.NOTE:
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.
NOTE:The coolant should be between theminimum and maximum level marks.
Recommended engine oil:
See page 8-1.
Oil quantity:
Without oil filter cartridge replace-
ment:
2.90 L (3.07 US qt) (2.55 Imp.qt)
With oil filter cartridge replacement:
3.10 L (3.28 US qt) (2.73 Imp.qt)

63. If the coolant is at or below the
minimum level mark, remove pan-
el A. (See page 6-7.)
4. Remove the reservoir cap, add
coolant to the maximum level
mark, and then install the reservoir
cap.
CAUTION:
ECA10471
If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion.
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness ofthe coolant will be reduced.WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
5. Install the panel.NOTE:
The radiator fans are automatically
switched on or off according to the
coolant temperature in the radia-
tor.
If the engine overheats, see page6-41 for further instructions.

Do not tilt or pull the fuel tank
too much, otherwise the fuel
hoses may come loose, whichcould cause fuel leakage.
5. Remove the air filter case cover by
removing the screws.
CAUTION:
ECA12880
When removing the air filter case
cover, be careful not to allow foreign
objects to drop into the air intakemanifold.
6. Pull the air filter element out.7. Insert a new air filter element into
the air filter case.
CAUTION:
ECA10480
Make sure that the air filter ele-
ment is properly seated in the
air filter case.
The engine should never be op-
erated without the air filter ele-
ment installed, otherwise the
piston(s) and/or cylinder(s) maybecome excessively worn.
8. Install the air filter case cover by in-
stalling the screws.
9. Place the fuel tank in the original
position and install the bolts.
WARNING
EWA11360
Before placing the fuel tank in
the original position, make sure
that the fuel hoses are not dam-
aged. If any fuel hose is dam-
aged, do not start the engine but
have a Yamaha dealer replace
the hose, otherwise fuel may
leak.
Make sure that the fuel hoses
are properly connected and
routed, and not pinched.
Be sure to place the fuel tank
breather hose and the fuel tank
overflow hose in the original po-sition.

follows at the intervals specified in the
periodic maintenance and lubrication
chart.
The engine should be warm before
making this adjustment.
Check the engine idling speed and, if
necessary, adjust it to specification by
turning the idle adjusting screw. To in-
crease the engine idling speed, turn the
screw in direction (a). To decrease the
engine idling speed, turn the screw in
direction (b).
NOTE:If the specified idling speed cannot be
obtained as described above, have aYamaha dealer make the adjustment.

Tires To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
WARNING
EWA10500
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).
The tire air pressure must be ad-
justed in accordance with the
riding speed and with the total
weight of rider, passenger, car-
go, and accessories approvedfor this model.
