NOTE:_ If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the en-
gine more than 10 seconds on any one
attempt. _
ECA00045
CAUTION:_ For maximum engine life, never ac-
celerate hard when the engine is
cold! _NOTE:_ The engine is warm when it quickly re-
sponds to the throttle. _
EAU00423
Shifting Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing hills,
etc.
The gear positions are shown in the il-
lustration.NOTE:_ To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it. _
EC000048
CAUTION:_

Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long dis-
tances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.


Always use the clutch while
changing gears to avoid dam-
aging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

6Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
NOTE:_ If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible. _
EAU04913
Engine oil and oil filter
cartridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_ Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result in
a false reading. _
2. Start the engine, warm it up for
several minutes, and then turn it off.
3. Wait a few minutes until the oil set-
tles, and then check the oil level
through the check window located
at the bottom-right side of the
crankcase.NOTE:_ The engine oil should be between the
minimum and maximum level marks. _4. If the engine oil is at or below the
minimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level. Tightening torque:

tion procedures.)
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Place an oil pan under the engine
to collect the used oil.4. Remove the engine oil filler cap
and drain bolt to drain the oil from

CAUTION:_

In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a
higher quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.


Make sure that no foreign mate-
rial enters the crankcase.
_10. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.NOTE:_ After the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient. _
EC000067
CAUTION:_ If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha deal-
er check the vehicle. _11. Turn the engine off, and then
check the oil level and correct it if
necessary.
12. Install the cowling.

EAU01357
Adjusting the brake pedal
position The top of the brake pedal should be
positioned approximately 38–42 mm
below the bottom of the footrest brack-
et as shown. Periodically check the
brake pedal position and, if necessary,
have a Yamaha dealer adjust it.
EW000109
WARNING
_ A soft or spongy feeling in the brake
pedal can indicate the presence of
air in the hydraulic system. If there
is air in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the motorcycle. Air in
the hydraulic system will diminish
the braking performance, which
may result in loss of control and an
accident. _

7-MOTORCYCLE CARE AND STORAGECare While the open design of a motorcycle
reveals the attractiveness of the tech-
nology, it also makes it more vulnera-
ble. Rust and corrosion can develop
even if high-quality components are
used. A rusty exhaust pipe may go un-
noticed on a car, however, it detracts
from the overall appearance of a
motorcycle. Frequent and proper care
does not only comply with the terms of
the warranty, but it will also keep your
motorcycle looking good, extend its life
and optimize its performance.Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and covers
as well as all electrical couplers
and connectors, including the
spark plug caps, are tightly in-
stalled.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-
ucts onto seals, gaskets, sprock-
ets, the drive chain and wheel
axles. Always rinse the dirt and
degreaser off with water.Cleaning
ECA00056
CAUTION:_

Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If such products are
used on hard-to-remove dirt, do
not leave the cleaner on the af-
fected area any longer than in-
structed. Also, thoroughly rinse
the area off with water, immedi-
ately dry it, and then apply a
corrosion protection spray.


Improper cleaning can damage
windshields, cowlings, panels,
other plastic parts, and the muf-
fler. Use only a soft, clean cloth
or sponge with mild detergent
and water to clean plastic. How-
ever, if the muffler cannot be
thoroughly cleaned with mild
detergent, alkaline products
and a soft brush may be used.
