Ignition circuit cut-off system The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.
It prevents starting when the side-
stand is up, but neither brake is ap-
plied.
It prevents starting when either
brake is applied, but the sidestand
is still down.
It cuts the running engine when the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.WARNING
EWA10260
The vehicle must be placed on
the centerstand during this in-
spection.
If a malfunction is noted, have a
Yamaha dealer check the sys-tem before riding.

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.
EAU40331
Starting the engine In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
The front or rear brake is applied
with the transmission in the neutral
position whether the sidestand is
up or down.
The front or rear brake is applied
with the transmission in gear and
the sidestand is up.WARNING
EWA14540
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-33.
Always apply the front or rear
brake while the main switch is in
the “ON” position and the trans-
mission is in gear, otherwise the
rear wheel will move freely.
Never ride with the sidestanddown.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “”.
CAUTION:

The following warning lights, indica-
tor light and indicators should come
on for a few seconds, then go off.

tors and warning light

light
ABS warning light
If a warning or indicator light, or an
indicator does not go off, see page
3-4 for the corresponding circuit
check.
2. Shift the transmission into the neu-
tral position with the front or rear
brake applied.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.
3. 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:

For maximum engine life, never ac-
celerate hard when the engine iscold!NOTE:The engine is warm when it quickly re-sponds to the throttle.
EAU40572
Shifting Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing hills,
etc.The gears can be shifted using either
the shift pedal or the hand shift lever.
The hand shift lever has to be enabled
by pressing the hand shift control
switch prior to being used. Refer to
page 3-17 for the shift pedal operation,
and to pages 3-16 and 3-18 for the
hand shift lever operation.
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, or push the “” side of the
hand shift lever repeatedly until theneutral indicator light comes on.CAUTION:
ECA15530
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 vehicle for long distanc-
es. The transmission is properly
lubricated only when the engine
is running. Inadequate lubrica-
tion may damage the transmis-
sion.

Always return the throttle to the
closed position while changing
gears to avoid damaging the en-
gine, transmission, and drive
train, which are not designed to
withstand the shock of forcedshifting.
NOTE:
When shifting from neutral to first
gear, the engine speed must be
lower than approximately 1300
r/min and the sidestand must be
up.
Shifting up is impossible if the en-
gine speed is too low.
Shifting down is impossible if theengine speed is too high.
EAU16810
Tips for reducing fuel con-
sumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
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).
EAU16841
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
EAU17121
0–1000 km (0–600 mi)
Avoid prolonged operation above 4500
r/min.
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 5400
r/min.

Checking the spark plugs The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they 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.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.
Clean 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.
Specified spark plug:
NGK/CR8E
DENSO/U24ESR-N1. Spark plug gapSpark plug gap:
0.7–0.8 mm (0.028–0.031 in)
Tightening torque:

Engine oil and oil filter car-
tridge 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 vehicle on the center-
stand.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.
NOTE:The engine oil should be between theminimum and maximum level marks.
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter cartridge replace-
ment)
1. Start the engine, warm it up for
several minutes, and then turn it
off.2. Place an oil pan under the engine
to collect the used oil.
3. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.
NOTE:Skip steps 4–6 if the oil filter cartridge isnot being replaced.
4. Remove the oil filter cartridge with
an oil filter wrench.
