Fuel cock
1. Fuel cock
The fuel cock supplies fuel from the
tank to the carburetor while filtering it
also.
The fuel cock has three positions:
OFF
With the lever in this position, fuel will
not flow. Always return the lever to
this position when the engine is not
running.
ON
With the lever in this position, fuel
flows to the carburetor. Normal riding
is done with the lever in this position.RES
This indicates reserve. If you run out
of fuel while riding, move the lever to
this position. Fill the tank at the first
opportunity. Be sure to set the lever
back to “ON” after refueling!

Starter (choke) lever “q”
1. Starter (choke) lever
Starting a cold engine requires a
richer air-fuel mixture, which is sup-
plied 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
1. 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.)
EWA10240
s s
WARNING
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.
EAU15311
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch,
clutch switch and neutral switch) has
the following functions.
It prevents starting when the
transmission is in gear and the
sidestand is up, but the clutch
lever is not pulled.
It prevents starting when the
transmission 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.

EAU15591
The condition of a vehicle is the
owner’s responsibility. Vital compo-
nents 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 inspection, to check the follo-
wing points before each ride.
NOTE:
Pre-operation checks should be
made each time the vehicle is used.
Such an inspection can be accom-
plished in a very short time; and the
added safety it assures is more than
worth the time involved.

WARNING
If any item in the Pre-operation
check list is not working properly,
have it inspected and repaired

WARNING
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or func-
tion that you do not thoroughly
understand.
Never start the engine or ope-
rate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of cons-
ciousness 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 comple-
tely, it could contact the
ground and distract the opera-
tor, resulting in a possible loss
of control.
EAU16050
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.
EWA10290
s s
WARNING
Before starting the engine,
check the function of the igni-
tion circuit cut-off system
according to the procedure
described on page 3-11.
Never ride with the sidestand
down.
1. Turn the fuel cock lever to “ON”.
2. Turn the key to “
f” and make
sure that the engine stop switch
is set to “
f”.
3. Shift the transmission into the
neutral position.
NOTE:
When the transmission is in the neu-
tral position, the neutral indicator lightshould be on, otherwise have a
Yamaha dealer check the electrical
circuit.
4. Turn the starter (choke) on and
completely close the throttle.
(See page 3-8.)
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
engine more than 10 seconds on any
one attempt.
ECA11410
CAUTION:
The 2-stroke engine oil level war-
ning light should come on when the
start switch is pushed, and it
should go off when the start switch
is released. If the warning light flic-
kers or remains on after starting,
immediately stop the engine, and
then check the 2-stroke engine oil
level and the vehicle for oil leakage.

If necessary, add 2-stroke 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 2-stro-
ke engine oil, have a Yamaha dealer
check the electrical circuit.
6. After starting the engine, move
the starter (choke) back halfway.
ECA11040
CAUTION:
For maximum engine life, never
accelerate 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.
EAU16640
Starting a warm engine
Follow the same procedure as for
starting a cold engine with the excep-
tion that the starter (choke) is not
required when the engine is warm.
EAU16671
Shifting
1. Shift pedal
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
illustration.
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 rai-
se it.
