9Owners are personally responsible for their vehicle’s condition. Your motorcycle/scooter’s vital functions can start to
deteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any dam-
age, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition
to a thorough visual inspection, you check the following points before each ride.

Before riding this motorcycle,
become thoroughly familiar
with all operating controls and
their functions. Consult a
Yamaha dealer regarding any
control or function that you do
not thoroughly understand.
8 8
Never start your engine or let
it run for any length of time in
a closed area. The exhaust
fumes are poisonous and can
cause loss of consciousness
and death within a short time.
Always operate your motorcy-
cle in an area with adequate
ventilation.
8 8
Before starting out, always be
sure the sidestand is up.
Failure to retract the sidestand
completely can result in a seri-
ous accident when you try to
turn a corner.
EAU00381Starting the engine

This motorcycle is equipped with an
ignition circuit cut-off system. The
engine can be started only under the
following conditions:
8 8
The transmission is in neutral.
8 8
The sidestand is up, the trans-
mission is in gear and the clutch
is disengaged
The motorcycle must not be ridden
when the sidestand is down.

2. Turn the main switch to “ON” and
the engine stop switch to “#“.
3. Shift transmission into neutral.
NOTE:
When the transmission is in neutral,
the neutral indicator light should be
on. If the light does not come on, ask
a Yamaha dealer to inspect it.
4. Turn on the starter (choke) and
completely close the throttle grip.
5. Start the engine by pushing the
start switch.
NOTE:
If the engine fails to start, release the
start switch, wait a few seconds, then
try again. Each attempt should be as
short as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one attempt.
EC000034

The oil level indicator light should
come on when the start switch is
pushed and should go off when
the start switch is released. If the
indicator light flickers or remains
on, immediately stop the engine
and check the engine oil level and
for oil leakage. If necessary, fill the
engine with oil and check to see
that the oil level indicator light
goes off. If the light does not go off
even with sufficient oil in the
crankcase or the light does not
come on when pushing the start
switch, consult a Yamaha dealer.
6. After starting the engine, move
the starter (choke) halfway back.
NOTE:
For maximum engine life, never
accelerate hard with a cold engine!
7. After the engine is warm, turn off
the starter (choke) completely.
NOTE:
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.

The starter (choke) is not required
when the engine is warm.
EC000046
cC
See the “Engine break-in” section
prior to operating the motorcycle
for the first time.
EAU00423Shifting
The transmission lets you control the
amount of power you have available
at a given speed for starting, acceler-
ating, climbing hills, etc. The use of
the shift pedal is shown in the illustra-
tion.
To shift into neutral, depress the shift
pedal repeatedly until it reaches the
end of its travel, then raise the pedal
slightly.
EC000048

Do not coast for long periods
with the engine off, and do not
tow the motorcycle a long dis-
tance. Even with gears in neu-
tral, the transmission is only
properly lubricated when the
engine is running. Inadequate
lubrication may damage the
transmission.
8 8
Always use the clutch when
changing gears. The engine,
transmission, and driveline are
not designed to withstand the
shock of forced shifting and
can be damaged by shifting
without using the clutch.

Tips for reducing fuel
consumption
Your motorcycle’s fuel consumption
depends to a large extent on your rid-
ing style. The following tips can help
reduce fuel consumption:
8Warm up the engine before rid-
ing.
8Turn off the starter (choke) as
soon as possible.
8Shift up swiftly and avoid high
engine speeds during accelera-
tion.
8Do not double-clutch or rev the
engine while shifting down and
avoid high engine speeds with
no load on the engine.
8Turn off the engine instead of let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traf-
fic lights or railroad crossings.
EAU00436Engine break-in
There is never a more important peri-
od in the life of your motorcycle than
the period between zero and 1,000
km. For this reason we ask that you
carefully read the following material.
Because the engine is brand new,
you must not put an excessive load
on it for the first 1,000 km. The vari-
ous parts in the engine wear and pol-
ish themselves to the correct operat-
ing clearances. During this period,
prolonged full throttle operation, or
any condition which might result in
excessive heating of the engine,
must be avoided.
