WARNING0
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.\4
1. Befo\be \befuel\fng, tu\bn off the en- g\fne and be su\be that no one \fs
s\ftt\fng on the veh\fcle. Neve\b \befuel
wh\fle smok\fng, o\b wh\fle \fn the

othe\b sou\bces of \fgn\ft\fon such as
the p\flot l\fghts of wate\b heate\bs
and clothes d\bye\bs.
2. Do not ove\bf\fll the fuel tank. When \befuel\fng, be su\be to \fnse\bt the
pump nozzle \fnto the fuel tank
f\flle\b hole. Stop f\fll\fng when the fu-
el \beaches the bottom of the f\flle\b
tube. Because fuel expands when
\ft heats up, heat f\bom the eng\fne
o\b the sun can cause fuel to sp\fll
out of the fuel ta\pnk.
1. Fuel tank f\flle\b tube
2. Fuel level
3. W\fpe up any sp\flled fuel \fmmed\f-ately. NOTICE: Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plas-
tic parts.
4. Be su\be to secu\bely close the fuel tank cap.
EWA15151
WARNING0
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swal-
low some gasoline or inhale a lot of
gasoline vapor, or get some gaso-
line in your eyes, see your doctor
immediately. If gasoline spills on
XT660Z 04-04 ING-AUS:MY03 01-03 ING 11-05-2009 9:54 Pagina 4-12
your skin, wash with soap and
water. I\f gasoline spills on your
clothing, change your clothes.

\bse only unleaded gasoline. The use
o\f leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha en\fine has been \besi\f-
ne\b to use premium unlea\be\b \fasoli-
ne with a research octane number of
95 or hi\fher. If knockin\f (or pin\fin\f)
occurs, use a \fasoline of a \bifferent
bran\b. Use of unlea\be\b fuel will
exten\b spark plu\f life an\b re\buce
maintenance costs.

Fuel tank breather/over\flow
hose
1. Fuel tank breather/hose
2. Hose clamp
Before operatin\f the motorcycle:
Check the fuel tank breather/over-
flow hose connection.
Check the fuel tank
breather/overflow hose for
cracks or \bama\fe, an\b replace it
if \bama\fe\b.
Make sure that the en\b of the fuel
tank breather/overflow hose is
not blocke\b, an\b clean it if
necessary.
Make sure that the en\b of the fuel
tank breather/overflow hose is
positione\b insi\be of the clamp.
EAU13433
Catalytic converters
This vehicle is equippe\b with catalytic
converters in the exhaust system.
EWA10862
The exhaust system is hot a\fter
operation. To prevent a \fire hazard
or burns:
Do not park the vehicle near
possible \fire hazards such as
grass or other materials that
easily burn.
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
Make sure that the exhaust
system has cooled down be\fo-
re doing any maintenance
work.
Do not allow the engine to idle
more than a \few minutes. Long
idling can cause a build-up o\f
heat.

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.

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.
