ECAM1060CAUTION:
The engine oil tank \fust be \billed in
2 steps. First, \bill the engine oil tank
with 1.90 L (2.0 US qt) (1.67 I\fp.qt)
o\b the reco\f\fended engine oil.
Then, start the engine, race it 5 or 6
ti\fes, turn it o\b\b, and then add the
re\fainder o\b the eng\kine oil.
NOTE:
Be sure to wipe off spi\f\fed oi\f on an\b
parts after the engine and exhaust
s\bstem have coo\fed d\fown.
ECA11620CAUTION: In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
\fix any che\fical additives. Do
not use oils with a diesel speci-
\bication o\b “CD” or oils o\b a
higher quality than speci\bied. In
addition, do not use oils la-
beled “ENERGY CONSERVING
II” or higher.
Make sure that no \boreign \fa-
terial enters the c\krankcase.
14. Start the engine, and then \fet it id\fe for severa\f minutes whi\fe
checking it for oi\f \feakage. If oi\f is
\feaking, immediate\f\b turn the en-
gine off and check for the \fcause.
15. Turn the engine off, and then check the oi\f \feve\f and correct it if
necessar\b.
16. Insta\f\f the engine guard b\b in- sta\f\fing the screws.\f

Coolant
The coo\fant \feve\f sho\fu\fd be checked
before each ride. In addition, the
coo\fant must be changed at the inter-
va\fs specified in the periodic mainte-
nance and \fubrication \fchart.
EAU20253
To check the coolant level1. P\face the vehic\fe on a \feve\f sur- face and ho\fd it in an upright posi-
tion.
NOTE:
The coo\fant \feve\f must be
checked on a co\fd engine since
the \feve\f varies with engine tem-
perature.
Make sure that the vehic\fe is posi-
tioned straight up when checking
the coo\fant \feve\f. A s\fight ti\ft to the
side can resu\ft in a \ffa\fse reading.
2. Check the coo\fant \feve\f in the coo\fant reservoir.
Reco\f\fended engine \koil:See page 8-1.
Oil quantity: Without oi\f fi\fter e\f\fement
rep\facement:2.50 L (2.64 US qt) (2.19 I\fmp.qt)
With oi\f fi\fter e\fem\fent rep\facement: 2.60 L (2.73 US qt) (2.26 Im\fp.qt)

Checking and lubricating
the cables
The opera\bio\f of all co\f\brol cables a\fd
\bhe co\fdi\bio\f of \bhe cables should be
checked before each ride, a\fd \bhe ca-
bles a\fd cable e\fds should be lubri-

aged or does \fo\b move smoo\bhly, have
a Yamaha dealer check or replace i\b.
W\fRNING! Damage to the outer
sheath may interfere with proper
cable operation and will cause the
inner cable to rust. Replace a dam-
aged cable as soon as possible to
prevent unsafe condit\Mions.

Long-term
Before storing your motorcycle for se\f-
eral months:\b. Follow all the instructions in the “Care” section of this ch\lapter.
2. Fill up the fuel tank and add fuel stabilizer (if a\failable) to pre\fent
the fuel tank from rusting and the
fuel from deteriorating.
3. Perform the following steps to protect the cylinder, piston rings,
etc. from corrosion.a. Remo\fe the spark plug cap and spark plug.
b. Pour a teaspoonful of engine oil into the spark plug bore.
c. Install the spark plug cap onto the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes
are grounded. (This will limit
sparking during the next step.)
d. Turn the engine o\fer se\feral times with the starter. (This will
coat the cylinder wall with oil.)
e. Remo\fe the spark plug cap from the spark plug, and then
install the spark plug and the
spark plug cap. W\fRNIN\b! To prevent damage or injury
from sparking, make sure to
ground the spark plug elec-
trodes while turning the en-
gine over.
4. Lubricate all control cables and the pi\foting points of all le\fers
and pedals as well as of the side-
stand/centerstand.\l
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. Alter-
nati\fely, turn the wheels a little
e\fery month in order to pre\fent
the tires from becoming degraded
in one spot.
6. Co\fer the muffler outlets with plastic bags to pre\fent moisture
from entering them. 7. Remo\fe the battery and fully
charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an ex-
cessi\fely cold or warm place [less
than 0 °C (30 °F) or more than 30
°C (90 °F)]. For more information
on storing the batter y, see
page 7-3\b.
TIP
Make any necessary repairs before
storing the motorcycle.
