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

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

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.

Insufficient brake fluid \fay allow air to
enter t\be brake syste\f, possibly caus-
ing it to beco\fe ine\dffective.
Before riding, c\beck t\bat t\be brake flu-
id is above t\be \fini\fu\f level \fark
and replenis\b if ne\dcessary.
A low brake fluid level \fay indicate
worn brake pads and/or brake syste\f
leakage. If t\be brake fluid level is low,
be sure to c\beck t\be brake pads for
wear and t\be brake syste\f for leak-
age.
Observe t\bese precautions\d:
●W\ben c\becking t\be fluid level,
\fake sure t\bat t\be top of t\be
brake fluid reservoir is level.
●Use only t\be reco\f\fended qual-
ity brake fluid, ot\berwise t\be rub-
ber seals \fay deteriorate, caus-
ing leakage and poor braking
perfor\fance.
●Refill wit\b t\be sa\fe type of brake
fluid. Mixing fluids \fay result in a
\bar\fful c\be\fical reaction and
lead to poor braking perfor\fance.
●Be careful t\bat water does not en-
ter t\be brake fluid reservoir w\ben
refilling. Water will significantly
lower t\be boiling point of t\be fluid
and \fay result in vapor lock.
●Brake fluid \fay deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid i\f\fe-
diately.
●As t\be brake pads wear, it is nor-
\fal for t\be brake fluid level to
gradually go down. However, if
t\be brake fluid level goes down
suddenly, \bave a Ya\fa\ba dealer
c\beck t\be cause.

Care
While the ope\f desig\f o\b a motorcycle
reveals the attractive\fess o\b the tech-
\fology, it also makes it more vul\fera-
ble. Rust a\fd corrosio\f ca\f develop
eve\f i\b high-quality compo\fe\fts are
used. A rusty exhaust pipe may go u\f-
\foticed o\f a car, however, it detracts
\brom the overall appeara\fce o\b a mo-
torcycle. Freque\ft a\fd proper care
does \fot o\fly comply with the terms o\b
the warra\fty, but it will also keep your
motorcycle looki\fg good, exte\fd its
li\be a\fd optimize its per\borma\fce.
Before cleaning 1. Cover the mu\b\bler outlet with a plastic bag a\bter the e\fgi\fe has
cooled dow\f.
2. Make sure that all caps a\fd cov- ers as well as all electrical cou-
plers a\fd co\f\fectors, i\fcludi\fg
the spark plug cap, are tightly i\f-
stalled. 3. Remove extremely stubbor\f dirt,
like oil bur\ft o\fto the cra\fkcase,
with a degreasi\fg age\ft a\fd a
brush, but \fever apply such prod-
ucts o\fto seals, gaskets, sprockets,
the drive chai\f a\fd wheel axles. Al-
ways ri\fse the dirt a\fd degreaser
o\b\b with water.
Cleaning
ECA10772
NOTICE
●Avoid using strong acidic
wheel cleaners, especially on
spoked wheels. If such prod-
ucts are used on hard-to-re-
move dirt, do not leave the
cleaner on the affected area
any longer than instructed. Al-
so, thoroughly rinse the area
off with water, immediately dry
it, and then apply a corrosion
protection spray.
●Improper cleaning can damage
plastic parts (such as cowlings,
panels, windshields, headlight
lenses, meter lenses, etc.) and
the mufflers. Use only a soft,
clean cloth or sponge with wa- ter to clean plastic. However, if
the plastic parts cannot be
thoroughly cleaned with water,
diluted mild detergent with wa-
ter may be used. Be sure to
rinse off any detergent residue
using plenty of water, as it is
harmful to plastic p\5arts.
●Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust re-
movers or inhibitors, brake flu-
id, antifreeze or electrolyte.
●Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the fol-
lowing areas: seals (of wheel
and swingarm bearings, fork
and brakes), electric compo-
nents (couplers, connectors,
instruments, switches and
lights), breather hoses and
vents.

ECA10810
NOTICE
●Storing the motorcycle in a
poorly ventilated room or cov-
ering it with a tarp, while it is
still wet, will allow water and
humidity to seep in and cause
rust.

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.
