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.
10. 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.
EAU20091
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.3. If the coolant is at or below the
minimum level mark, remove the
reservoir cap.

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.NOTE:

The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.


If the engine overheats, see page6-37 for further instructions.
EAU42610
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Place a container under the engine
to collect the used coolant.
3. Remove the radiator cap retaining
bolt, radiator cap retainer and radi-
ator cap.

66. Drain the coolant from the coolant
reservoir by turning it upside down.
7. Install the coolant reservoir and its
reservoir cover by placing them in
the original position, and then in-
stalling the bolts.
8. Remove the coolant drain bolt to
drain the cooling system.9. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
10. Install the coolant drain bolt, and
then tighten it to the specified
torque.
NOTE:
Check the washer for damage and re-place it if necessary.
11. Pour the specified amount of the
recommended coolant into the ra-
diator and reservoir.

otherwise the effectiveness of
the coolant will be reduced.
12. Install the coolant reservoir cap.
13. Install the radiator cap, radiator
cap retainer and radiator cap re-
taining bolt.
14. Start the engine, let it idle for sev-
eral minutes, and then turn it off.
15. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap, radiator cap retainer and radi-
ator cap retaining bolt.16. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
17. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.

Replacing the air filter element The air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Replace the air filter element
more frequently if you are riding in un-
usually wet or dusty areas.
1. Remove the seat. (See page
3-18.)
2. Remove the fuel tank bolts, and
then lift the fuel tank away from the
air filter case.
3. Remove the air filter case cover by
removing the screws.

6Engine overheating
WARNING
EWA10400


Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.


After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hissingsound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
NOTE:If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolantas soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
