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. 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.)
3. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all (even chrome-
and nickel-plated) metal surfaces.
4. Use spray oil as a universal clean-
er to remove any remaining dirt.
5. Touch up minor paint damage
caused by stones, etc.
6. Wax all painted surfaces.
7. 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 neces-
sary, clean the brake discs and lin-
ings with a regular brake disc
cleaner or acetone, and wash the
tires with warm water and mild
soap. Then, carefully test the motor-
cycle for its braking performance
and cornering behavior.
ECA00013
CAUTION:

l
Apply spray oil and wax spar-
ingly and wipe off any excess.
l
Never apply oil or wax on rubber
and plastic parts, but treat them
with a suitable care product.
l
Avoid 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:

l
Storing 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.
l
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 sev-
eral months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Drain the carburetor float cham-
bers by loosening the drain bolts;
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
“OFF” position: Turn the fuel cock
to “OFF”.
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 cylinders, piston rings,
etc. from corrosion.
a. Remove the spark plug caps and
spark plugs.
b. Pour a teaspoonful of engine oil
into each spark plug bore.c. Install the spark plug caps onto
the spark plugs and place the
spark plugs on the cylinder head
so that the electrodes are ground-
ed. (This will limit sparking during
the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder walls with oil.)
e. Remove the spark plug caps from
the spark plugs, install the spark
plugs and then the spark plug
caps.
EWA00003
WARNING

When turning the engine over, be
sure to ground the spark plug elec-
trodes to prevent damage or injury
from sparking.
6. Lubricate all control cables and
the pivoting points of all levers and
pedals as well as of the side-
stand/centerstand.

CAUTION:Be sure to use motor oils that do not contain anti-fric-
tion modifiers. Passenger car motor oils (often labeled
“Energy Conserving”) contain anti-friction additives
which will cause clutch and/or starter clutch slippage,
resulting in reduced component life and poor engineperformance.
