cleaning products, solvent or
thinner, fuel (gasoline), rust
removers or inhibitors, brake
fluid, antifreeze or electrolyte.
●Do not use high-pressure was-
hers or steam-jet cleaners sin-
ce they cause water seepage
and deterioration in the follo-
wing areas: seals (of wheel and
swingarm bearings, fork and
brakes), electric components
(couplers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
●For scooters equipped with a
windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or scrat-
ching. Some cleaning com-
pounds for plastic may leave
scratches on the windshield.
Test the product on a small hid-
den part of the windshield to
make sure that it does not lea-
ve any marks. If the windshield
is scratched, use a quality
plastic polishing compound
after washing.
After normal use
1. Remove dirt with warm water, a
mild detergent, and a soft, clean
sponge, and then rinse tho-
roughly with clean water. Use a
toothbrush or bottlebrush for
hard-to-reach areas. Stubborn
dirt and insects will come off
more easily if the area is covered
with a wet cloth for a few minutes
before cleaning.
After riding in the rain, near the sea or
on salt-sprayed roads
1. Since sea salt or salt sprayed on
the roads during winter are extre-
mely corrosive in combination
with water, carry out the following
steps after each ride in the rain,
near the sea or on salt-sprayed
roads.
TIP
Salt sprayed on roads in the winter
may remain well into spring.
1. Clean the scooter with cold water
and a mild detergent after the
engine has cooled down. NOTI-
CE:Do not use warm watersince it increases the corrosive
action of the salt.
[ECA10791]
2. Apply a corrosion protection
spray on all metal, including
chrome- and nickel-plated, surfa-
ces to prevent corrosion.
After 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 indu-
ced 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, inclu-
ding chrome- and nickel-plated,
surfaces.
4. Use spray oil as a universal clea-
ner 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.

EWA10941
sWARNING
Contaminants on the brakes or
tires can cause loss of control.
●Make 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.
●Before operating the scooter
test its braking performance
and cornering behavior.
ECA10800
NOTICE
●Apply spray oil and wax spa-
ringly and make sure to wipe
off any excess.
●Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
●Avoid using abrasive polishing
compounds as they will wear
away the paint.
TIP
Consult a Yamaha dealer for advice
on what products to use.EAU26301
Storage
Short-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 chemi-
cals are stored.
Long-term
Before storing your scooter for seve-
ral months:
1. Follow all the instructions in the
“Care” 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 drai-
ned fuel into the fuel tank.
