EAU15596
Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always follow the inspection
and maintenance procedures and schedules described in the Owner’s Manual.
WARNING
EWA11151
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment damage.
Do not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures provided inthis manual, have the vehicle inspected by a Yamaha dealer.
Before using this vehicle, check the following points:
ITEM CHECKS PAGE
FuelCheck fuel level in fuel tank.
Refuel if necessary.
Check fuel line for leakage.3-15
Engine oilCheck oil level in engine.
If necessary, add recommended oil to specified level.
Check vehicle for oil leakage.6-9
CoolantCheck coolant level in reservoir.
If necessary, add recommended coolant to specified level.
Check cooling system for leakage.6-12
Front brakeCheck operation.
If soft or spongy, have Yamaha dealer bleed hydraulic system.
Check brake pads for wear.
Replace if necessary.

6 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.
TIPAfter the engine is started, the engine
oil level warning light should go off if theoil level is sufficient.
NOTICE
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.
12. Install the cowling.
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.
EAU46801
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.TIP

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.
TIPThe coolant should be between theminimum and maximum level marks.

63. If the coolant is at or below the
minimum level mark, remove the
coolant reservoir breather hose
from the guide, and then remove
the coolant reservoir cap.4. Add coolant to the maximum level
mark, and then install the coolant
reservoir cap. WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.
[EWA15161]
NOTICE: If
coolant is not available, use dis-
tilled water or soft tap water in-
stead. 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 coolant as soon as possi-
ble, otherwise the cooling sys-
tem will not be protectedagainst 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.

To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove cowling A and panel B.
(See page 6-7.)
3. Place a container under the engine
to collect the used coolant.
4. Remove the radiator cap retaining
bolt, radiator cap retainer and radi-
ator cap. WARNING! Never at-
tempt to remove the radiator
cap when the engine is hot.

69. 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.
TIPCheck the washer for damage and re-place it if necessary.
11. Install the coolant reservoir and its
reservoir cover by placing them in
the original position, and then in-
stalling the bolts.
12. Pour the specified amount of the
recommended coolant into the ra-
diator and reservoir.13. Install the radiator cap.
14. Install the coolant reservoir cap.
15. Start the engine, let it idle for sev-
eral minutes, and then turn it off.
16. 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.17. 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.

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.
TIPIf 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 TIP.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.
