Tips for reducing fuel
consumption
Your motorcycle’s fuel consumption
depends to a large extent on your rid-
ing style. The following tips can help
reduce fuel consumption:
8Warm up the engine before rid-
ing.
8Turn off the starter (choke) as
soon as possible.
8Shift up swiftly and avoid high
engine speeds during accelera-
tion.
8Do not double-clutch or rev the
engine while shifting down and
avoid high engine speeds with
no load on the engine.
8Turn off the engine instead of let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traf-
fic lights or railroad crossings.
EAU00436Engine break-in
There is never a more important peri-
od in the life of your motorcycle than
the period between zero and 1,000
km. For this reason we ask that you
carefully read the following material.
Because the engine is brand new,
you must not put an excessive load
on it for the first 1,000 km. The vari-
ous parts in the engine wear and pol-
ish themselves to the correct operat-
ing clearances. During this period,
prolonged full throttle operation, or
any condition which might result in
excessive heating of the engine,
must be avoided.

Spark plug inspection
The spark plug is an important
engine component and should be
inspected periodically, preferably by
a Yamaha dealer. The condition of
the spark plug can indicate the condi-
tion of the engine. The ideal color on
the white insulator around the center
electrode is a medium-to-light tan
color for a motorcycle that is being
ridden normally. Do not attempt to
diagnose any problems yourself.
Instead, take the motorcycle to a
Yamaha dealer. The spark plug
should be periodically removed and
inspected because heat and depositswill cause the spark plug to slowly
break down and erode. If electrode
erosion becomes excessive, or if car-
bon and other deposits are exces-
sive, the spark plug should be
replaced with the specified plug.
Before installing the spark plug, mea-
sure the electrode gap with a wire
thickness gauge and adjust it to
specification.When installing the plug, the gasket
surface should always be cleaned
and a new gasket used. Any grime
should be wiped off from the threads
and the spark plug tightened to the
specified torque.NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4
to 1/2 turn past finger tight. The spark
plug should be tightened to the speci-
fied torque as soon as possible.

2. With the engine stopped, check
the oil level through the level
window located at the right side
crankcase cover.
NOTE:
Wait a few minutes until the oil level
settles before checking.
3. The oil level should be above the
minimum level mark on the level
window. If the level is low, add
sufficient oil to raise it to the
proper level.Transmission oil replacement
1. Warm up the engine for several
minutes.
2. Stop the engine. Place an oil pan
under the engine and remove the
oil filler cap.

Oil level measurement
1. Place the motorcycle on a level
place and hold it an upright posi-
tion. Warm up the engine for
several minutes.
NOTE:
Be sure the motorcycle is positioned
straight up when checking the oil
level. A slight tilt toward the side can
result in false readings.

A soft or spongy feeling in the
brake pedal can indicate the pres-
ence of air in the brake system.
This air must be removed by
bleeding the brake system before
the motorcycle is operated. Air in
the system will cause greatly
diminished braking capability and
can result in loss of control and an
accident. Have a Yamaha dealer
inspect and bleed the system if
necessary.

Brake light switch
adjustment
The rear brake light switch is activat-
ed by the brake pedal and is properly
adjusted when the brake light comes
on just before braking takes effect.
To adjust the rear brake light switch,
hold the switch body so it does not
rotate while turning the adjusting nut.
Turn the adjusting nut in direction a
to make the brake light come on earli-
er.
Turn the adjusting nut in direction b
to make the brake light come on
later.

replace the bulb as follows:
1. Remove cowling A and B. (See
page 6-7 for removal and instal-
lation procedures.)
2. Disconnect the headlight con-
nector and remove the bulb hold-
er cover.

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.
6. Install the bulb holder cover.
7. Install the headlight connector
and the cowling.
If the headlight beam adjustment
is necessary, ask a Yamaha
dealer to make adjustment.

Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent
and water to clean plastic.
8 8
Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abra-
sive cleaning products, sol-
vent or thinner, fuel (gasoline),
rust removers or inhibitors,
brake fluid, antifreeze or elec-
trolyte.8 8
Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the
following areas: seals (of
wheel bearings, swingarm
bearings, forks and brakes),
electric components (cou-
plers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
8 8
For motorcycles equipped
with a windshield: Do not use
strong cleaners or hard
sponges as they will cause
dulling or scratching. Some
cleaning compounds for plas-
tic may leave scratches on the
windshield. Test the product
on a small hidden part of the
windshield to make sure they
do not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com-
pound after washing.After riding in the rain, near the sea
or on salt-sprayed roads
Since sea salt or salt sprayed on the
roads in the winter are extremely cor-
rosive in combination with water,
carry out the following steps after
each ride in the rain, near the sea or
on salt-sprayed roads. (Salt sprayed
in the winter may remain on the roads
well into spring.)
1. Clean your motorcycle with cold
water and soap after the engine
has cooled down.
ECA00012
cC
Do not use warm water since it
increases 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.
