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.

CHECKING THE TIRES
EB304170
CHECKING THE TIRES
The following procedure applies to both of
the tires.
1. Measure:
• tire pressure
Out of specification ® Regulate.
WARNINGWARNING
• The tire pressure should only be
checked and regulated when the tire
temperature equals the ambient air
temperature.
• The tire pressure and the suspension
must be adjusted according to the
total weight (including cargo, rider,
passenger and accessories) and the
anticipated riding speed.
• Operation of an overloaded motorcy-
cle could cause tire damage, an acci-
dent or an injury.
NEVER OVERLOAD THE MOTORCYCLE.

WARNINGWARNING
It is dangerous to ride with a worn-out
tire. When the tire tread reaches the
wear limit, replace the tire immediately.Basic weight

WARNINGWARNING
• Do not use a tubeless tire on a wheel
designed only for tube tires to avoid
tire failure and personal injury from
sudden deflation.
• When using a tube tire, be sure to
install the correct tube.
• Always replace a new tube tire and a
new tube as a set.
• To avoid pinching the tube, make sure
that the wheel rim band and tube are
centered in the wheel groove.
• Patching a punctured tube is not rec-
ommended. If it is absolutely neces-
sary to do so, use great care and
replace the tube as soon as possible
with a good quality replacement.

WARNINGWARNING
After mounting a new tire, ride conser-
vatively for a while to become accus-
tomed to the “feel” of the new tire and
to allow the tire to seat itself properly in
the rim. Failure to do so could lead to an
accident with possible injury to the rider
or damage to the motorcycle.
NOTE:
For tires with a direction of rotation
mark 1:
• Install the tire with the mark pointing
in the direction of wheel rotation.
• Align the mark 2 with the valve instal-
lation point.
