TIP
The coolant should be between the
\fini\fu\f and \faxi\fu\f level \fa\bks.
1. Coolant \bese\bvoi\b
2. Maxi\fu\f level \fa\bk
3. Mini\fu\f level \fa\bk
4. Rese\bvoi\b cap
3. If the coolant is at o\b below the\fini\fu\f level \fa\bk, \be\fove pan-
el E (See page 7-7.), \be\fove the
\bese\bvoi\b cap, add coolant to the
\faxi\fu\f level \fa\bk, and then in-
stall the \bese\bvoi\b cap and the
panel. W\fRNING! Remove only
the coolant reservoir cap. Nev-
er attempt to remove the radia-
tor cap when the engine is hot.
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 wa-
ter has been used instead of
coolant, replace it with coolant
as soon as possible, otherwise
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 an-
tifreeze content of the coolant
as soon as possible, otherwise
the effectiveness of the coolant
will be reduced.
Coolant reservoir capacity
(up to the maximum\M level mark): 0.50 L (0.52 US qt\w) (0.44 I\fp.
EAU33031
Changing the coolant
The coolant \fust be changed at the
inte\bvals specified in the pe\biodic
\faintenance and lub\bication cha\bt.
Have a Ya\faha deale\b change the
coolant. W\fRNING! Never attempt
to remove the radiator cap when
the engine is hot.\M

●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 cau\Mse serious injury. Be sure to wait until th\Me engine has coole\Md.
●\ffter 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 hiss-
ing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
TIP
If coolant is not a\failable, ta\b water can be tem\borarily used instead, \bro\fided that it is changed to the recommended
coolant as soon as \b\sossible.
Wait until the
engine has cooled.Check the coolant le\fel
in the reser\foir and radiator.
The coolant le\fel is low.
Check the cooling
system for leakage.
The coolant le\fel
is OK.
There is
leakage.
There is no
leakage.
Ha\fe a Yamaha dealer check
and re\bair the cooling system.
Start the engine. If the engine o\ferheats again, ha\fe
a Yamaha dealer check and re\bair the coo\sling system.
Add coolant. (See TIP.)

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.
