6 11. Install and tighten the engine oil
filler cap.
12. 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.
TIPAfter the engine is started, the engine
oil pressure warning light should go off.
NOTICE
ECA20860
If the oil pressure warnin g li ght flick-
ers or remains on even if the oil level
is correct, imme diately turn the en-
g ine off an d have a Yamaha d ealer
check the vehicle.13. Turn the engine off, wait a few mi- nutes until the oil settles, and then
check the oil level and correct it if
necessary.
EAU20071
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.
EAU20095
To check the coolant level1. Place the vehicle on a level surfa- ce 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 tem-
perature.
 Make sure that the vehicle is posi-
tioned 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.TIPThe coolant should be between the mi-
nimum and maximum level marks.

3. If the coolant is at or below the mi-
nimum level mark, remove the res-
ervoir cap. WARNING! Remove
only the coolant reservoir cap.
Never attempt to remove the ra-
d iator cap when the en gine is
hot.
[EWA15162]
4. Add coolant to the maximum level mark, and then install the reservoir
cap. NOTICE: If coolant is not
availa ble, use distille d water or
soft tap water instead . Do not
use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has b een
a dd ed to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as soon as possi
ble, otherwise the
effectiveness of the coolant will
b e re duce d.
[ECA10473]
EAU59863
To change the coolant
1. Place the vehicle on a level surfa- ce and let the engine cool if neces-
sary.
2. Place a container under the en- gine to collect the used coolant.
3. Remove the radiator cap retaining bolt and radiator cap. WARNING!
Never attempt to remove the ra-
d iator cap when the en gine is
hot.

12. Install the coolant reservoir cap.
13. Install the radiator cap.
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 radi-
ator, and then install the radiator
cap and radiator 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.

Replacin g the air filter ele-
ment an d cleaning the check
hoseThe air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Have a Yamaha dealer replace
the air filter element more frequently if
you are riding in unusually wet or dusty
areas. However, the air filter check
hose can be easily reached and should
be frequently checked and cleaned if
necessary.
To clean the air filter check hose
1. Remove the air filter check hose under the air filter case.
Antifreeze/water mixture ratio:1:1
Recommen ded antifreeze:

freeze containing corrosion inhibi-
tors for aluminum engines

Valve clearanceThe valve clearance changes with use,
resulting in improper air-fuel mixture
and/or engine noise. To prevent this
from occurring, the valve clearance
must be adjusted by a Yamaha dealer
at the intervals specified in the periodic
maintenance and lubrication chart.

WARNING
EWA10401
Do not remove the ra diator cap when the en gine an d ra diator are hot. Scal din g hot flui d an d steam may be
b lown out un der pressure, which coul d cause serious injury. Be sure to wait until the en gine has coole d.
 After removin g the ra diator cap retainin g b olt, place a thick ra g, like a towel, over the ra diator cap, an d then
slowly rotate the cap counterclockwise to the detent to allow any resid ual pressure to escape. When the hiss-
in g soun d has stopped , press down on the cap while turnin g it counterclockwise, an d then remove the cap.TIPIf coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended cool-
ant as 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.

Start the engine. If the engine overheats again,
have a

2. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
3. Perform the following steps to protect the cylinders, piston rings,
etc. from corrosion.a. Remove the spark plug caps and spark plugs.
b. Pour a teaspoonful of engine oil into each spark plug bore.
c. Install the spark plug caps onto the spark plugs, and then pla-
ce the spark plugs on the cylin-
der head so that the electrodes
are grounded. (This will limit
sparking during the next step.)
d. Turn the engine over several times with the starter. (This will
coat the cylinder walls with oil.)
WARNING! To prevent dam-
a g e or injury from sparkin g,
make sure to groun d the
spark plu g electro des while
turning the en gine over.
[EWA10952]
e. Remove the spark plug caps
from the spark plugs, and then
install the spark plugs and the
spark plug caps.
4. Lubricate all control cables and the pivoting points of all levers and
pedals as well as of the side-
stand/centerstand.
5. Check and, if necessary, correct the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
6. Cover the muffler outlet with a plastic bag to prevent moisture
from entering it.
7. Remove the battery and fully char- ge it. Store it in a cool, dry place
and charge it once a month. Do
not store the battery in an exces-
sively cold or warm place [less
than 0 °C (30 °F) or more than 30
°C (90 °F)]. For more information
on storing the battery, see page
6-31.
TIPMake any necessary repairs before
storing the motorcycle.

Vehicle data recor din gThis model’s ECU stores certain vehi-
cle data to assist in the diagnosis of
malfunctions and for research and de-
velopment purposes. This data will be
uploaded only when a special Yamaha
diagnostic tool is attached to the vehi-
cle, such as when maintenance checks
or service procedures are performed.
Although the sensors and recorded
data will vary by model, the main data
points are:
 Vehicle status and engine perfor-
mance data
 Fuel-injection and emission-relat-
ed data
Yamaha will not disclose this data to a third party except:  With the consent of the vehicle
owner
 Where obligated by law
 For use by Yamaha in litigation
 For general Yamaha-conducted
research purposes when the data
is not related to an individual vehi-
cle nor owner
