Kickstarter To start the engine, fold out the kick-
starter lever, move it down lightly with
your foot until the gears engage, and
then push it down smoothly but force-
fully. This model is equipped with a pri-
mary kickstarter, allowing the engine to
be started in any gear if the clutch is
disengaged. However, shifting the
transmission into the neutral position
before starting is recommended.

OPERATION AND IMPORTANT RIDING POINTS
EAU15951
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING
EWA10271
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accidentor injury.

TIPThis model is equipped with:
a lean angle sensor to stop the en-
gine in case of a turnover. In this
case, the multi-function display in-
dicates error code 30, but this is
not a malfunction. Push the main
switch to “OFF” and then to “ON”
to clear the error code. Failing to
do so will prevent the engine from
starting even though the engine
will crank when pushing the start
switch.

an engine auto-stop system. The
engine stops automatically if left
idling for 20 minutes. In this case,
the multi-function display indicates
error code 70, but this is not a mal-
function. Push the start switch to
clear the error code and to restartthe engine.

Starting a cold engine NOTICE
ECA11042
For maximum engine life, never ac-
celerate hard when the engine iscold!
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.
See page 3-19 for more informa-
tion.
1. Push the main switch to “ON” and make sure that the engine stop
switch is set to “ ”.
The following warning lights

remains on, see page 3-1 for the cor-
responding warning light circuit
check.
2. Shift the transmission into the neu- tral position. The neutral indicator
light should come on. If not, ask a
Yamaha dealer to check the elec-
trical circuit.
3. Turn the starter on and completely close the throttle. (See page 3-12.)
4. Start the engine by pushing the start switch or by pushing the kick-
starter lever down.
If the engine fails to start when us-
ing the start switch, release it, wait
a few seconds, and then try again.
Each starting attempt should be as
short as possible to preserve the
battery. Do not crank the engine
more than 10 seconds on any one
attempt. If the engine does not
start with the starter motor, try us-
ing the kickstarter.NOTICE
ECA17801
If the starter motor will not turn when
the start switch is pushed, stop pushing it immediately in order to
avoid placing extra load on the start-
er motor, and start the engine by us-
ing the kickstarter.TIPUse the kickstarter when the ambient
temperature is below 10
C (50 F) orwhen at high altitude.
5. When the engine is warm, turn the starter off.TIPThe engine is warm when it responds
quickly to the throttle with the starterturned off.
Starting with the kickstarter
When using the kickstarter to start the
engine, follow the procedures as de-
scribed below.1. Fold out the kickstarter lever, push it down lightly with your foot until
resistance is felt. 2. With the throttle fully closed, push
the kickstarter down lightly until the
gears engage, and then push it
down smoothly but forcefully.
WARNING
EWA16381
Do not open the throttle while kick-
ing the kickstarter lever. Otherwise,the kickstarter lever may kick back.

TIPIf the engine fails to start, push the main
switch to “OFF” and give the kickstarter
10 to 20 slow kicks at full throttle in or-
der to clear the engine of the rich air-fu-el mixture retained in it.
EAU52971
Starting a warm engine Follow the same procedure as for start-
ing a cold engine with the exception
that the starter is not required when the
engine is warm.TIP
If the engine does not start at high
altitude, start the engine with the
throttle grip opened by one degree
or two degrees.

The mark on the throttle housing
indicates five degrees. Use the
mark for your reference whenopening the throttle grip.

amount of engine power available for
starting off, accelerating, climbing hills,
etc.
The gear positions are shown in the il-
lustration.TIPTo 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.NOTICE

9the 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.
EAU16810
Tips for reducing fuel
consumption 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).

WARNING
EWA10321
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer performservice.
1. Before starting the engine, fill the fuel tank with the fuel.
2. Start and warm up the engine. Check the operation of the controls
and the engine stop switch. (See
page 3-7.) Then, restart the engine
and check its operation within no
more than 5 minutes after it is re-
started.
3. Operate the motorcycle in the low- er gears at moderate throttle open-
ings for five to eight minutes. Stop
the engine.
4. Check how the engine runs when the motorcycle is ridden with the
throttle 1/4 to 1/2 open (low to me-
dium speed) for about one hour.

EAU19622
Checking the spark plug The spark plug is an important engine
component, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode, it
should be removed and checked in ac-
cordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plug can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of the spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally). If
the spark plug shows a distinctly differ-
ent color, the engine could be operating
improperly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If the spark plug shows signs of elec-
trode 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
