8The engine should never be
run without the air filter
installed. Excessive piston
and/or cylinder wear may
result.

98Use only the designated quali-
ty brake fluid. Otherwise, the
rubber seals may deteriorate,
causing leakage and poor
brake performance.
NOTE:
If DOT 4 is not available, DOT 3 can
be used.
8Refill with the same type of
brake fluid. Mixing fluids may
result in a harmful chemical
reaction and lead to poor
brake performance.
8Be careful that water does not
enter the master cylinder when
refilling. Water will significant-
ly lower the boiling point of
the fluid and may result in
vapor lock. Recommended brake fluid:

EAU00732Inspecting the brake fluid
level
Insufficient brake fluid may let air
enter the brake system, possibly
causing the brakes to become inef-
fective.
Before riding, check that the brake
fluid is above the minimum level
and fill when necessary.
Observe these precautions:
8When checking the fluid level,
make sure the top of the mas-
ter cylinder is level by turning
the handlebars.

The brake fluid should be replaced
only by trained Yamaha service
personnel. Have the Yamaha deal-
er replace the following compo-
nents during periodic maintenance
or when they are damaged or leak-
ing:
8oil seals (every two years)

EAU00744Drive chain slack check
NOTE:
Spin the wheel several times and
find the tightest position of the
chain. Check and/or adjust the
chain slack while it’s in this tightest
position.
To check the chain slack the motor-
cycle must be held straight up with
both wheels on the ground and
without rider. Check the slack at
the position shown in the illustra-
tion. Normal slack is approximately
30 ~ 40 mm. If the slack exceeds
40 mm, adjust.

EAU00769Drive chain lubrication
The chain consists of many parts
which work with each other. If the
chain is not maintained properly, it
will wear out quickly. Therefore,
the chain must be serviced regular-
ly. This service is especially neces-
sary when riding in dusty areas.
This motorcycle is equipped with a
sealed type chain. Steam cleaning,
high-pressure washes, and sol-
vents can damage chain so do not
use these for cleaning it. Use only
kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubri-
cate it with SAE 30 ~ 50W motor
oil. Do not use any other lubricants
on the drive chain. They may con-
tain solvents that could damage
the sealed chain.

EAU00773Throttle cable and grip
lubrication
The throttle twist grip assembly
should be greased at the time that
the cable is lubricated, since the
grip must be removed to get at the
end of the throttle cable. After
removing the screws, hold the end
of the cable up in the air and put in
several drops of lubricant. With the
throttle grip disassembled, coat the
metal surface of the grip assembly
with a suitable all-purpose grease.

ing the motorcycle or riding in the

Damage to the outer housing of
cables may lead to internal rusting
and interfere with the cable move-

soon as possible to prevent unsafe
conditions.
Lubricate the cables and cable ends.
If a cable does not operate smooth-
ly, ask a Yamaha dealer to replace it.

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.

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.

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.

tors and headlight unit.

MOTORCYCLE CARE AND STORAGE
7-1
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.
