12 And do not touch the radiator
pipe after high-speed operation,
otherwise the cooling system is
hot and cause burns. Always let
the engine oil cool down suffi-
ciently before removing the oil
tank cap.
[EWA16141]

NOTICE: Do not
operate the vehicle until you
know that the engine oil level is
sufficient.
[ECA10012]
4. The engine oil should be above the minimum level mark. If the engine
oil level is above the minimum lev-
el mark, continue to the next step.
If the engine oil level is below the
minimum level mark, remove the
engine oil filler cap and add the
recommended oil to bring the en-
gine oil level above the minimum
level mark.
5. Place an oil pan under the engine and then remove the engine oil
check bolt and gasket. 6. The engine oil level should be be-
low the level of the check bolt hole.
If any oil does come out, allow it to
drain.

8. Install the engine oil check bolt and gasket, and then tighten the bolt to
the specified torque.
9. Start the engine and warm it up for a few minutes. Then turn the en-
gine off and wait a few minutes to
allow the oil to settle. Use the en-
gine oil tank cap and dipstick to
confirm that the engine oil level is
correct.
To change the engine oil (with or
without oil filter element 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 guard by re- moving the bolts. 5. Remove the engine oil tank cap
and the engine oil filler cap.
6. Remove the engine oil drain bolts and their gasket to drain the oil from the oil tank and crankcase.

CoolantThe 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.
EAUM1296
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. Remove the radiator cap and check the coolant level in the radi-
ator. WARNING! Never attempt
to remove the radiator cap when
the engine is hot.
[EWA10382]
TIPThe coolant should be at the bottom of
the radiator filler neck. The level will
change with variation of engine temper-ature. 3. If the coolant is below the correct
coolant level, add coolant, and
then install the radiator cap.
NOTICE: If coolant is not avail-
able, 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 cool-
ant, replace it with coolant as
soon as possible, otherwise the
cooling system will not be pro-
tected against frost and corro-
sion. If water has been added to
the coolant, have a Yamaha
dealer check the antifreeze con-
tent of the coolant as soon as
possible, otherwise the effec-
tiveness of the coolant will be
reduced.
[ECA10473]

To change the coolant1. 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.

its gasket, and then the radiator
cap to drain the cooling system.
WARNING! Never attempt to re-
move the radiator cap when the
engine is hot.
[EWA10382]
4. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
5. Install the coolant drain bolt and its new gasket, and then tighten the
bolt to the specified torque.
6. Pour the recommended coolant into the radiator until it is full.
7. Install the radiator cap, start the engine, let it idle for several min-
utes, and then turn it off.
8. Remove the radiator cap to check the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the bottom of the
radiator filler neck, and then install
the radiator cap.
9. Start the engine, and then check the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.

Cleaning the air filter element
and check hoseThe air filter element should be cleaned
or replaced at the intervals specified in
the periodic maintenance and lubrica-
tion chart. Clean or, if necessary, re-
place the air filter element more
frequently if you are riding in unusually
wet or dusty areas. In addition, the air
filter check hose must be frequently
checked and cleaned if necessary.
To clean the air filter element
1. Open the air filter case cover by loosening the quick fastener screw
and pulling the case cover outward
as shown.
