MOTORCYCLE CARE AND STORAGE
Care
The exposure of its technology makes
a motorcycle charming but also vulner-
able. Although high-quality compo-
nents are used, they are not all rust-
resistant. While a rusty exhaust pipe
may remain unnoticed on a car, it does
look unattractive on a motorcycle. Fre-
quent and proper care, however, will
keep your motorcycle looking good, ex-
tend its life and maintain its perfor-
mance. Moreover, the warranty states
that the vehicle must be properly taken
care of. For all these reasons, it is rec-
ommended that you observe the fol-
lowing cleaning and storing
precautions.Before cleaning
1. Cover up the muffler outlet with a
plastic bag.
2. Make sure that all caps and cov-
ers as well as all electrical cou-
plers and connectors, including
the spark plug caps, are tightly in-
stalled.
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, sprock-
ets, the drive chain and wheel
axles. Always rinse the dirt and
degreaser off with water.Cleaning
After normal useRemove dirt with warm water, a neutral
detergent and a soft clean sponge,
then rinse with plenty of clean water.
Use a tooth or bottle brush for hard-to-
reach parts. Tougher dirt and insects
will come off more easily if the area is
covered with a wet cloth for a few min-
utes before cleaning.
MOTORCYCLE CARE AND STORAGE
ECA00010
CAUTION:
lAvoid using strong acidic
wheel cleaners, especially on
spoked wheels. If you do use
such products for hard-to-re-
move dirt, do not leave it on any
longer than instructed, then
thoroughly rinse it off with wa-
ter, immediately dry the area
and apply a corrosion protec-
tion spray.
lImproper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent and
water to clean plastic.
lDo 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.
lDo 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
bearings, swingarm bearings,
forks and brakes), electric com-
ponents (couplers, connectors,
instruments, switches and
lights), breather hoses and
vents.
lFor motorcycles equipped with
a windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning
compounds for plastic may
leave scratches on the wind-
shield. Test the product on a
small hidden part of the wind-
shield to make sure they do not
leave any marks. If the wind-
shield is scratched, use a quali-
ty plastic polishing compound
after washing.
lDo not rub the frame, swingarm
and other similar matte metal
parts with a cloth (neither one
dampened with solvents or
gasoline nor a dry one), as this
may deteriorate their finish.
Wash off dirt with water only.
For hard-to-remove dirt, add a
mild detergent and rub only
lightly.
After riding in the rain, near the sea or
on salt-sprayed roads
Since sea salt or salt sprayed on the
roads in the winter are extremely corro-
sive in combination with water, carry
out the following steps after each ride
in the rain, near the sea or on salt-
sprayed roads. (Salt sprayed in the
winter may remain on the roads well
into spring.)
1 - 16
MOTORCYCLE CARE AND STORAGE
1. Clean your motorcycle with cold
water and soap after the engine
has cooled down.
ECA00012
CAUTION:
Do not use warm water since it in-
creases the corrosive action of the
salt.
2. Be sure to apply a corrosion pro-
tection spray on all (even chrome-
and nickel-plated) metal surfaces
to prevent corrosion.After cleaning
1. Dry the motorcycle with a cham-
ois or an absorbing cloth.
2. Immediately dry the drive chain
and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally in-
duced discoloring of stainless-
steel exhaust systems can be re-
moved through polishing.)
4. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all (even chrome-
and nickel-plated) metal surfaces.
5. Use spray oil as a universal clean-
er to remove any remaining dirt.
6. Touch up minor paint damage
caused by stones, etc.
7. Wax all painted surfaces.
CAUTION:
Do not wax the frame, swingarm and
other similar matte metal parts, as
this may deteriorate their finish.
8. Let the motorcycle dry completely
before storing it or covering it.
EWA00001
WARNING
Make sure that there is no oil or wax
on the brakes and tires. If necessary,
clean the brake discs and linings
with a regular brake disc cleaner or
acetone, and wash the tires with
warm water and mild soap. Then,
carefully test the motorcycle for its
braking performance and cornering
behavior.
ECA00013
CAUTION:
lApply spray oil and wax spar-
ingly and wipe off any excess.
lNever apply oil or wax on rub-
ber and plastic parts, but treat
them with a suitable care prod-
uct.
lAvoid using abrasive polishing
compounds as they wear away
the paint.
NOTE:
Consult a Yamaha dealer for advice on
what products to use.
Storage
Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA00014
CAUTION:
lStoring the motorcycle in a
poorly ventilated room or cov-
ering it with a tarp while it is still
wet will allow water and humid-
ity to seep in and cause rust.
lTo prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.Long-term
Long term storage (60 days or more) of
your motorcycle will require some pre-
ventive procedures to guard against
deterioration. After throughly cleaning
the motorcycle, prepare for storage as
follows:
1. Drain the fuel tank.
2. Remove the empty fuel tank, pour
a cup of engine oil in the tank,
shake the tank to coat the inner
surfaces thoroughly and drain off
the excess oil. Reinstall the tank.
3. Remove the spark plug, pour
about one tablespoon of engine
oil in the spark plug hole and rein-
stall the spark plug. Turn the en-
gine over several times (ground
spark plug lead wires) to coat the
cylinder walls with oil.
