9After cleaning
1.Dry the motorcycle with a
chamois 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
induced discoloring of stainless-
steel exhaust systems can be
removed 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
cleaner to remove any remaining
dirt.
6.Touch up minor paint damage
caused by stones, etc.
7.Wax all painted surfaces.
8.Let the motorcycle dry complete-
ly before storing it or covering it.

wMake sure that there is no oil or
wax on the brakes and tires. If nec-
essary, 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 perfor-
mance and cornering behavior.

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

StorageShort-term
Always store your motorcycle in a
cool, dry place and, if necessary, pro-
tect it against dust with a porous
cover.
ECA00014
cC8
8
Storing the motorcycle in a
poorly ventilated room or cov-
ering it with a tarp while it is
still wet will allow water and
humidity to seep in and cause
rust.
8 8
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 motorcycle for
several 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.Only for motorcycles equipped
with a fuel cock which has an
ÒOFFÓ position: Turn the fuel
cock to ÒOFFÓ.
4.Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5.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 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, install the spark
plug and then the spark plug
cap.
EWA00003
wWhen turning the engine over, be
sure to ground the spark plug elec-
trodes to prevent damage or injury
from sparking.

96.Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
7.Check and, if necessary, correct
the tire air pressure, then raise
the motorcycle 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.
8.Cover up the muffler outlet with a
plastic bag to prevent moisture
from entering.9.Remove the battery and fully
charge it. Store it in a cool, dry
place and recharge 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, see ÒBattery storageÓ in the
chapter ÒPERIODIC MAINTE-
NANCE AND MINOR
REPAIRSÓ.
NOTE:
Make any necessary repairs before
storing the motorcycle.
