Fuel tank breather hose Before operating the motorcycle:
Check the fuel tank breather hose
connection.
Check the fuel tank breather hose
for cracks or damage, and replace
it if damaged.
Make sure that the end of the fuel
tank breather hose is not blocked,
and clean it if necessary.

Fuel cock The fuel cock supplies fuel from the
tank to the carburetors while also filter-
ing it.
The fuel cock lever positions are ex-
plained as follows and shown in the il-
lustrations.
ON
With the fuel cock lever in this position,
fuel flows to the carburetors when the
engine is running. Turn the fuel cock le-
ver to this position when starting the
engine and riding.RES
This indicates reserve. With the fuel
cock lever in this position, the fuel re-
serve is made available. Quickly turn
the fuel cock lever to this position if you
run out of fuel while riding, otherwise
the engine may stall and will have to be
primed (see “PRI”). After turning the
fuel cock lever to “RES”, refuel as soon
as possible and be sure to turn the fuel
cock lever back to “ON”!

PRI
This indicates prime. With the fuel cock
lever in this position, the engine can be
“primed”. Turn the fuel cock lever to
this position when the engine has been
allowed to run out of fuel. This sends
fuel directly to the carburetors, which
will make starting easier. After the en-
gine has started, be sure to turn the le-
ver to “ON” (or “RES” if you have not
refueled yet).

Starter (choke) lever “” Starting a cold engine requires a richer
air-fuel mixture, which is supplied by
the starter (choke).
Move the lever in direction
a to turn on
the starter (choke).
Move the lever in direction
b to turn off
the starter (choke).

Sidestand The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
motorcycle upright.NOTE:_ The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation of
the ignition circuit cut-off system.) _
EW000044
WARNING
_ The motorcycle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up), oth-
erwise the sidestand could contact
the ground and distract the opera-
tor, resulting in a possible loss of
control. Yamaha’s ignition circuit
cut-off system has been designed to
assist the operator in fulfilling the
responsibility of raising the side-
stand before starting off. Therefore,
check this system regularly as de-
scribed below and have a Yamaha
dealer repair it if it does not function
properly. _
EAU03741
Ignition circuit cut-off system The ignition circuit cut-off system (com-
prising the sidestand switch, clutch
switch and neutral switch) has the fol-
lowing functions.
It prevents starting when the trans-
mission is in gear and the side-
stand is up, but the clutch lever is
not pulled.
It prevents starting when the trans-
mission is in gear and the clutch
lever is pulled, but the sidestand is
still down.
It cuts the running engine when
the transmission is in gear and the
sidestand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.

4-PRE-OPERATION CHECKSThe condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.
EAU03439
Pre-operation check list

5-OPERATION AND IMPORTANT RIDING POINTS
EAU00373
WARNING
_
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 loss
of control.
_
EAU00381*
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
sidestand up.
EW000054
WARNING
_
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-19.
Never ride with the sidestand
down.
_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 for starter (choke) oper-
ation.)
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 one
attempt. _

CAUTION:_ The oil level warning light should
come on when the start switch is
pushed, and it should go off when
the start switch is released. If the oil
level warning light flickers or re-
mains on after starting, immediately
stop the engine, and then check the
engine oil level and the vehicle for
oil leakage. If necessary, add engine
oil, and then check the warning light
again. If the warning light does not
come on when pushing the start
switch, or if it does not go off after
starting with sufficient engine oil,
have a Yamaha dealer check the
electrical circuit. _6. After starting the engine, move the
starter (choke) lever back halfway.

CAUTION:_ For maximum engine life, never ac-
celerate hard when the engine is
cold! _
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. _
EAU01258
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.
