EAU00794Steering inspection
Periodically inspect the condition
of the steering. Worn out or loose
steering bearings may be danger-
ous. Place a stand under the
engine to raise the front wheel off
the ground. Hold the lower end of
the front forks and try to move
them forward and backward. If any
free play can be felt, ask a Yamaha
dealer to inspect and adjust the
steering. Inspection is easier if the
front wheel is removed.
PERIODIC MAINTENANCE AND MINOR REPAIR
Operation check
1. Place the motorcycle on a level
place.
2. Hold the motorcycle in an
upright position and apply the
front brake.
3. Push down hard on the han-
dlebars several times and
check if the fork rebounds
smoothly.

If any damage or unsmooth move-
ment is found with the front fork,
consult a Yamaha dealer.

Replenishing the battery fluid
A poorly maintained battery will
corrode and discharge quickly. The
battery fluid should be checked at
least once a month. The level
should be between the minimum
level and maximum level marks.
Use only distilled water if refilling
is necessary.

When inspecting the battery, be
sure the breather hose is routed
correctly. If the breather hose is
positioned in such a way as to
cause battery electrolyte or gas to
exit onto the frame, structural and
cosmetic damage to the motorcy-
cle can occur.
EW000116
w
Battery electrolyte is poisonous
and dangerous, causing severe
burns, etc. It contains sulfuric acid.
Avoid contact with skin, eyes or
clothing.
ANTIDOTE:
8EXTERNAL: Flush with water.
8INTERNAL: Drink large quanti-
ties of water or milk. Follow
with milk of magnesia, beaten
egg, or vegetable oil. Call a
physician immediately.
8EYES: Flush with water for 15
minutes and get prompt med-
ical attention.
Batteries produce explosive gases.
Keep sparks, flame, cigarettes etc.,
away. Ventilate when charging or
using in an enclosed space.
Always shield your eyes when
working near batteries.
KEEP OUT OF REACH OF CHIL-
DREN.

Avoid touching the glass part of a
bulb. Keep it free from oil; other-
wise, the transparency of the
glass, life of the bulb, and lumi-
nous flux will be adversely affect-
ed. If oil gets on a bulb, thoroughly
clean it with a cloth moistened
with alcohol or lacquer thinner.

Ask a Yamaha dealer to adjust
the headlight beam if neces-
sary.

Care
The exposure of its technology
makes a motorcycle charming but
also vulnerable. Although high-
quality components 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.
Frequent and proper care, howev-
er, will keep your motorcycle look-
ing good, extend its life and main-
tain its performance. Moreover, the
warranty states that the vehicle
must be properly taken care of. For
all these reasons, it is recommend-
ed that you observe the following
cleaning and storing precautions.
Before cleaning
1. Cover up the muffler outlets
with plastic bags.
2. Make sure that all caps and
covers as well as all electrical
couplers and connectors,
including the spark plug caps,
are tightly installed.
3. Remove extremely stubborn
dirt, like oil burnt onto the
crankcase, with a degreasing
agent and a brush, but never
apply such products onto
seals, gaskets, sprockets, the
drive chain and wheel axles.
Always rinse the dirt and
degreaser off with water.Cleaning
After normal use
Remove 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 cov-
ered with a wet cloth for a few
minutes before cleaning.
ECA00010
cC
8Avoid using strong acidic
wheel cleaners, especially on
spoked wheels. If you do use
such products for hard-to-
remove dirt, do not leave it on
any longer than instructed,
then thoroughly rinse it off
with water, immediately dry
the area and apply a corrosion
protection spray.

MOTORCYCLE CARE AND STORAGE

After cleaning
1. Dry the motorcycle with a
chamois or an absorbing cloth.
2. Immediately dry the drive
chain and lubricate it to pre-
vent it from rusting.
3. Use a chrome polish to shine
chrome, aluminum and stain-
less-steel parts, including the
exhaust system. (Even the
thermally induced discoloring
of stainless-steel exhaust sys-
tems can be removed through
polishing.)
4. To prevent corrosion, it is rec-
ommended to apply a corro-
sion protection spray on all
(even chrome- and nickel-plat-
ed) metal surfaces.
5. Use spray oil as a universal
cleaner to remove any remain-
ing dirt.
6. Touch up minor paint damage
caused by stones, etc.
7. Wax all painted surfaces.
8. Let the motorcycle dry com-
pletely before storing it or cov-
ering it.EWA00001
w
Make 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.
ECA00013
cC
8Apply spray oil and wax spar-
ingly and wipe off any excess.
8Never apply oil or wax on rub-
ber and plastic parts, but treat
them with a suitable care
product.
8Avoid 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
cC
8Storing 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.
8To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chem-
icals are stored.
Long-term
Before storing your motorcycle for
several months:
1. Follow all the instructions in
the “Care” section of this
chapter.
2. Drain the carburetor float
chambers 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 rust-
ing and the fuel from deterio-
rating.
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
grounded. (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
w
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
sidestand/centerstand.

Be sure to use motor oils that do not contain anti-friction
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 engine performance.
