WARNING
EWA10270
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible lossof control.
EAU16400
Starting a cold engine In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
The transmission is in the neutral
position.
The transmission is in gear with
the clutch lever pulled and the sid-
estand up.WARNING
EWA10290
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-15.
Never ride with the sidestanddown.
1. Turn the fuel cock lever to “ON”.
2. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
3. Shift the transmission into the neu-
tral position.
NOTE:When the transmission is in the neutral
position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical cir-cuit.
4. Turn the starter (choke) on and
completely close the throttle. (See
page 3-11.)
5. Start the engine by pushing the
start switch.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 oneattempt.CAUTION:
ECA11370
The engine trouble warning light
should come on when the key is
turned to “ON”, and then go off after
a few seconds. If the engine trouble
warning light comes on or flashes

5 after starting, immediately stop the
engine, and have a Yamaha dealer
check the self-diagnosis system.
6. After starting the engine, move the
starter (choke) back halfway.CAUTION:
ECA11040
For maximum engine life, never ac-
celerate hard when the engine iscold!
7. When the engine is warm, turn the
starter (choke) off.NOTE:The engine is warm when it responds
normally to the throttle with the starter(choke) turned off.
EAU16640
Starting a warm engine Follow the same procedure as for start-
ing a cold engine with the exception
that the starter (choke) is not required
when the engine is warm.
EAU16671
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 itstravel, and then slightly raise it.1. Shift pedal

CAUTION:
ECA10260
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 damag-
ing the engine, transmission,
and drive train, which are not
designed to withstand theshock of forced shifting.
EAU32810
Recommended shift points (for
Switzerland only)
The recommended shift points during
acceleration are shown in the table be-
low.
NOTE:When shifting down two gears at a
time, reduce the speed accordingly
[e.g., down to 35 km/h (22 mi/h) whenshifting from 4th to 2nd gear].
EAU16800
Tips for reducing fuel
consumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
Turn the starter (choke) off as
soon as possible.
Shift up swiftly, and avoid high en-
gine speeds during acceleration.
Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.
Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
Shift up points:
1st → 2nd: 23 km/h (14 mi/h)
2nd → 3rd: 36 km/h (22 mi/h)
3rd → 4th: 50 km/h (31 mi/h)
4th → 5th: 60 km/h (37 mi/h)

NOTE:
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
Hydraulic brake service
Regularly check and, if necessary, correct the brake fluid level.
Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid.Replace the brake hoses every four years and if cracked or damaged.

Checking the spark plugs The spark plugs are important engine
components, which are easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plugs should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
To remove a spark plug
1. Remove the spark plug cap.
2. Remove the spark plug as shown,
with the spark plug wrench includ-
ed in the owner’s tool kit.To check the spark plugs
1. Check that the porcelain insulator
around the center electrode on
each spark plug is a medium-to-
light tan (the ideal color when the
vehicle is ridden normally).
2. Check that all spark plugs installed
in the engine have the same color.
NOTE:If any spark plug shows a distinctly dif-
ferent color, the engine could be defec-
tive. Do not attempt to diagnose such
problems yourself. Instead, have aYamaha dealer check the vehicle.

63. Check each spark plug for elec-
trode erosion and excessive car-
bon or other deposits, and replace
it if necessary.
To install a spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.2. Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then tight-
en it 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 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-fied torque as soon as possible.
4. Install the spark plug cap.

Engine oil and oil filter
element The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.NOTE:
Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in afalse 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-left side of the crank-
case.

Final gear oil The final gear case must be checked
for oil leakage before each ride. If any
leakage is found, have a Yamaha deal-
er check and repair the vehicle. In addi-
tion, the final gear oil level must be
checked and the oil changed as follows
at the intervals specified in the periodic
maintenance and lubrication chart.
WARNING
EWA10370
Make sure that no foreign mate-
rial enters the final gear case.
Make sure that no oil gets on thetire or wheel.
To check the final gear oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
NOTE:
The final gear oil level must be
checked on a cold engine.
Make sure that the vehicle is posi-
tioned straight up when checking
the oil level. A slight tilt to the sidecan result in a false reading.2. Remove the oil filler bolt, and then
check the oil level in the final gear
case.
NOTE:The oil level should be at the brim of thefiller hole.
3. If the oil is below the brim of the fill-
er hole, add sufficient oil of the rec-
ommended type to raise it to the
correct level.
To change the final gear oil
1. Place an oil pan under the final
gear case to collect the used oil.2. Remove the oil filler bolt and drain
bolt to drain the oil from the final
gear case.
3. Install the final gear oil drain bolt,
and then tighten it to the specified
torque.
4. Add the recommended final gear
oil to the brim of the filler hole.
NOTE:GL4 is a quality rating. Hypoid gear oilsrated GL5 or GL6 may also be used.
5. Install and tighten the oil filler bolt.
6. Check the final gear case for oil
leakage. If oil is leaking, check for
the cause.
