Matte color cautionNOTICE
ECA15193
Some models are equipped with
matte colored finished parts. Be
sure to consult a Yamaha dealer for
advice on what products to use be-
fore cleaning the vehicle. Using a
brush, harsh chemical products or
cleaning compounds when cleaning
these parts will scratch or damage
their surface. Wax also should not
be applied to any matte colored fin-
ished parts.
EAU83443
CareFrequent, thorough cleaning of the ve-
hicle will not only enhance its appear-
ance but also will improve its general
performance and extend the useful life
of many components. Washing, clean-
ing, and polishing will also give you a
chance to inspect the condition of the
vehicle more frequently. Be sure to
wash the vehicle after riding in the rain
or near the sea, because salt is corro-
sive to metals.TIPThe roads of heavy snowfall areas
may be sprayed with salt as a de-
icing method. This salt can stay on
the roads well into spring, so be
sure to wash the underside and
chassis parts after riding in such
areas.
Genuine Yamaha care and main-
tenance products are sold under
the YAMALUBE brand in many
markets worldwide.
See your Yamaha dealer for addi-
tional cleaning tips.
NOTICE
ECA26280
Improper cleaning can cause cos-
metic and mechanical damage. Do
not use:
high-pressure washers or
steam-jet cleaners. Excessive
water pressure may cause wa-
ter seepage and deterioration of
wheel bearings, brakes, trans-
mission seals and electrical de-
vices. Avoid high-pressure
detergent applications such as
those available in coin-operated
car washers.
harsh chemicals, including
strong acidic wheel cleaners,
especially on spoke or magne-
sium wheels.
harsh chemicals, abrasive
cleaning compounds, or wax on
matte-finished parts. Brushes
can scratch and damage the
matte-finish, use soft sponge or
towel only.

10chemicals such as, solvents,
gasoline, rust removers, brake
fluid, or antifreeze, etc.
Before washing
1. Park the vehicle out of direct sun-
light and allow it to cool. This will
help avoid water spots.
2. Make sure all caps, covers, elec-
trical couplers and connectors are
tightly installed.
3. Cover the muffler end with a plas-
tic bag and a strong rubber band.
4. Pre-soak stubborn stains like in-
sects or bird droppings with a wet
towel for a few minutes.
5. Remove road grime and oil stains
with a quality degreasing agent
and a plastic-bristle brush or
sponge. NOTICE: Do not use
degreasing agent on areas re-
quiring lubrication such as
seals, gaskets, and wheel axles.
Follow product instructions.
[ECA26290]
Washing
1. Rinse off any degreaser and spray
down the vehicle with a garden
hose. Use only enough pressure
to do the job. Avoid spraying wa-
ter directly into the muffler, instru-
ment panel, air inlet, or other inner
areas such as underseat storage
compartments.
2. Wash the vehicle with a quality au-
tomotive-type detergent mixed
with cool water and a soft, clean
towel or sponge. Use an old tooth-
brush or plastic-bristle brush for
hard-to-reach places. NOTICE:
Use cold water if the vehicle has
been exposed to salt. Warm wa-
ter will increase salt’s corrosive
properties.
[ECA26301]
3. For windshield-equipped vehicles:
Clean the windshield with a soft
towel or sponge dampened with
water and a pH neutral detergent.
If necessary, use a high-quality
windshield cleaner or polish for
motorcycles. NOTICE: Never use
any strong chemicals to clean
the windshield. Additionally,
some cleaning compounds forplastic may scratch the wind-
shield, so be sure to test all
cleaning products before gen-
eral application.
[ECA26310]
4. Rinse off thoroughly with clean
water. Be sure to remove all deter-
gent residues, as they can be
harmful to plastic parts.
After washing
1. Dry the vehicle with a chamois or
absorbent towel, preferably mi-
crofiber terrycloth.
2. For drive chain-equipped models:
Dry and then lubricate the drive
chain to prevent rust.
3. Use a chrome polish to shine
chrome, aluminum, and stainless
steel parts. Often the thermally in-
duced discoloring of stainless
steel exhaust systems can be re-
moved through polishing.
4. Apply a corrosion protection spray
on all metal parts including
chrome or nickel-plated surfaces.
WARNING! Do not apply sili-
cone or oil spray to seats, hand
grips, rubber foot pegs or tire
treads. Otherwise these parts

101. Make all necessary repairs and
perform any outstanding mainte-
nance.
2. Follow all instructions in the Care
section of this chapter.
3. Fill up the fuel tank, adding fuel
stabilizer according to product in-
structions. Run the engine for 5
minutes to distribute treated fuel
through the fuel system.
4. For vehicles equipped with a fuel
cock: Turn the fuel cock lever to
the off position.
5. For vehicles with a carburetor: To
prevent fuel deposits from build-
ing up, drain the fuel in the carbu-
retor float chamber into a clean
container. Retighten the drain bolt
and pour the fuel back into the fuel
tank.
6. Use a quality engine fogging oil
according to product instructions
to protect internal engine compo-
nents from corrosion. If engine
fogging oil is not available, per-
form the following steps for each
cylinder:
a. Remove 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 spark-
ing during the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder wall with oil.)
WARNING! To prevent dam-
age or injury from sparking,
make sure to ground the
spark plug electrodes while
turning the engine over.
[EWA10952]
e. Remove the spark plug cap
from the spark plug, and then
install the spark plug and the
spark plug cap.
7. Lubricate all control cables, piv-
ots, levers and pedals, as well as
the sidestand and centerstand (if
equipped).
8. Check and correct the tire air
pressure, and then lift the vehicle
so that all wheels are off the
ground. Otherwise, turn thewheels a little once a month in or-
der to prevent the tires from be-
coming degraded in one spot.
9. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
10. Remove the battery and fully
charge it, or attach a maintenance
charger to keep the battery opti-
mally charged. NOTICE: Confirm
that the battery and its charger
are compatible. Do not charge a
VRLA battery with a convention-
al charger.
[ECA26330]
TIPIf the battery will be removed,
charge it once a month and store
it in a temperate location between
0-30 °C (32-90 °F).
See page 9-28 for more informa-
tion on charging and storing the
