Matte color caution
ECA15192
NOTICESome models are equipped with
matte colored finished parts. Be sure
to consult a Yamaha dealer for ad-
vice on what products to use before
cleaning the vehicle.
Using a brush, harsh chemical prod-
ucts or cleaning compounds when
cleaning these parts will scratch or
damage their surface. Wax also
should not be applied to any matte
colored finished parts.Matte color, caution
Care
EAU26093
CareWhile the open design of a scooter re-
veals the attractiveness of the technol-
ogy, it also makes it more vulnerable.
Rust and corrosion can develop even if
high-quality components are used. A
rusty exhaust pipe may go unnoticed on
a car, however, it detracts from the over-
all appearance of a scooter. Frequent and
proper care does not only comply with
the terms of the warranty, but it will also
keep your scooter looking good, extend
its life and optimize its performance.
Before cleaning
1. Cover the muffler outlet with a plas-
tic bag after the engine has cooled
down.
2. Make sure that all caps and cov-
ers as well as all electrical couplers
and connectors, including the spark
plug cap, are tightly installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-ucts onto seals, gaskets and wheel
axles. Always rinse the dirt and
degreaser off with water.
Cleaning
ECA10782
NOTICE● ●● ●
●
Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If such products are used
on hard-to-remove dirt, do not
leave the cleaner on the affected
area any longer than instructed.
Also, thoroughly rinse the area
off with water, immediately dry it,
and then apply a corrosion pro-
tection 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 water
to clean plastic. However, if the
plastic parts cannot be thor-
oughly cleaned with water, di-

stabilizer (if available) to prevent the
fuel tank from rusting and the fuel
from deteriorating.
3. Perform the following steps to pro-
tect the cylinder, piston rings, etc.
from corrosion.
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.)
e. Remove the spark plug cap from
the spark plug, and then install
the spark plug and the spark plug
cap. WARNING! To  prevent  dam-
age or injury from sparking,
make sure to ground the sparkplug electrodes while turning
the engine over.
[EWA10951]
4. Lubricate all control cables and the
pivoting points of all levers and
pedals as well as of the sidestand/
centerstand.
5. Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
6. Cover the muffler outlet with a plas-
tic bag to prevent moisture from en-
tering it.
7. Remove 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 excessively cold
or warm place [less than 0 °C (30
°F) or more than 30 °C (90 °F)]. For
more information on storing the
battery, see page 6-19. Storage
EAU36561
StorageShort-term
Always store your scooter in a cool, dry
place and, if necessary, protect it against
dust with a porous cover.
ECA10820
NOTICE● ●● ●
●
Storing the scooter in a poorly
ventilated room or covering it
with a tarp, while it is still wet,
will allow water and humidity to
seep in and cause rust.
● ●● ●
●
To prevent corrosion, avoid
damp cellars, stables (because of
the presence of ammonia) and
areas where strong chemicals are
stored.
Long-term
Before storing your scooter for several
months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Fill up the fuel tank and add fuel
