Engine oil and oil filter
cartridge 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 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 sev-
eral 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 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 cartridge replace-
ment)
1. Remove cowling A. (See page 6-5
for cowling removal and installa-
tion procedures.)
2. Start the engine, warm it up for
several minutes, and then turn it
off.

64. 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 is
not being replaced. _
5. Remove the oil filter cartridge with
an oil filter wrench.NOTE:_ An oil filter wrench is available at a
Yamaha 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 properly
seated. _7. Install the new oil filter cartridge,
and then tighten it to the specified
torque with a torque wrench.

9. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.

CAUTION:_
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 grade “CD”
or higher. In addition, do not
use oils labeled “ENERGY CON-
SERVING 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,
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. _11. Turn the engine off, and then
check the oil level and correct it if
necessary.

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.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
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.
_
2. Check the coolant level in the
coolant reservoir.NOTE:_ The coolant should be between the
minimum and maximum level marks. _3. If the coolant is at or below the
minimum level mark, remove the
seat (See page 3-11 for seat re-
moval and installation proce-
dures.), and then open the coolant
reservoir cap.
4. Add coolant or distilled water to
raise the coolant to the specified
level, close the coolant reservoir
cap, and then install the seat.
EC000080
CAUTION:_
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 engine may not be
sufficiently cooled and the cool-
ing 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 of
the coolant will be reduced.

tor cap when the engine is hot. _NOTE:_
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.
If the engine overheats, see

To change the coolant
1. Place the motorcycle on a level
surface and let the engine cool if
necessary.
