9After cleaning
1.Dry the scooter with a chamois
or an absorbing cloth.
2.Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally
induced discoloring of stainless-
steel exhaust systems can be
removed through polishing.)
3.To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal, includ-
ing chrome- and nickel-plated,
surfaces.
4.Use spray oil as a universal
cleaner to remove any remaining
dirt.
5.Touch up minor paint damage
caused by stones, etc.6.Wax all painted surfaces.
7.Let the scooter dry completely
before storing or covering it.
EWA00002
w8Make sure that there is no oil
or wax on the brakes or tires.
If necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or
acetone, and wash the tires
with warm water and a mild
detergent.
8Before operating the scooter
test its braking performance
and cornering behavior.

cC8Apply spray oil and wax spar-
ingly and make sure to wipe
off any excess.
8Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
8Avoid using abrasive polish-
ing compounds as they will
wear away the paint.NOTE:
Consult a Yamaha dealer for advice
on what products to use.

SCOOTER CARE AND STORAGE
7-4
StorageShort-term
Always store your scooter in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA00015
cC8Storing 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.
8To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
Long-term
Before storing your scooter for sever-
al months:
1.Follow all the instructions in the
ÒCareÓ section of this chapter.
2.Drain the carburetor float cham-
ber by loosening the drain bolt;
this will prevent fuel deposits
from building up. Pour the
drained fuel into the fuel tank.
3.Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
4.Perform the following steps to
protect 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.
EWA00003
wTo prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turn-
ing the engine over.

95.Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
6.Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground.
Alternatively, turn the wheels a
little every month in order to pre-
vent the tires from becoming
degraded in one spot.
7.Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.8.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 or more
than 30 ¡C). For more informa-
tion on storing the battery, see
page 6-32.
NOTE:
Make any necessary repairs before
storing the scooter.

Engine oil
Type
Recommended engine oil
classificationAPI Service SE, SF, SG type
or highercCBe sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled ÒEnergy
ConservingÓ) contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting in reduced
component life and poor engine performance.
