TIP
U\fing the alignment mark\f on each
\fide of the \fwingarm, make \f\bre that
both chain p\bller\f are in the \fame po-
\fition for proper wheel al\nignment.
3. Tighten the axle n\bt, then the lock- n\bt\f to their \fpecified torq\be\f.
Tightening torques:
Axle n\bt:105 Nm (10.5 m·kgf, 75 ft·lbf)
Lockn\bt: 16 Nm (1.6 m·kgf, 11 ft·lbf)
EAU34314
To adjust the drive chain slack1. Loo\fen the axle n\bt and the lock- n\bt on each \fide of the \fwingarm.
2. To tighten the drive chain, t\brn the drive chain \flack adj\b\fting bolt on
each \fide of the \fwingarm in di-
rection (a). To loo\fen the drive
chain, t\brn the adj\b\fting bolt on
each \fide of the \fwingarm in di-
rection (b), and then p\b\fh the rear
wheel forward. NOTICE: Improp-
er drive chain slack will over-
load the engine as well as other
vital parts of the motorcycle
and can lead to chain slippage
or breakage. To prevent this
from occurring, keep the drive
chain slack within the specified
limits.

To prevent damaging the O-
rings, do not clean the drive
chain with steam cleaners,
high-pressure washers or inap-
propriate solvents. 2. Wipe \bhe drive chai\f dry.
3. Thoroughly lubrica\be \bhe drive
chai\f wi\bh a special O-ri\fg chai\f
lubrica\f\b. NOTICE: Do not use
engine oil or any other lubri-
cants for the drive chain, as
they may contain substances
that could damage the O-rings.

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-
ca\bed if \fecessary. If a cable is dam-
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.
Recommended lubrican\Mt: E\fgi\fe oil

●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.
