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.

TIPThis model is equipped with a lean an-
gle sensor to stop the engine in case of
a turnover. To start the engine after a
turnover, be sure to turn the main
switch to “OFF” and then to “ON”. Fail-
ing to do so will prevent the engine from
starting even though the engine will
crank when pushing the start switch.
EAUM2323
Starting the 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 sid-
estand up.
See page 3-12 for more informa-
tion.
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to“”.
The following warning lights and
indicator light should come on for a
few seconds, then go off.
Neutral indicator light
Turn signal indicator light
High beam indicator light
Coolant temperature warning
light
Engine trouble warning light

3-2 for the corresponding warning
and indicator light circuit check.
2. Shift the transmission into the neu-
tral position. (See page 5-2.) The
neutral indicator light should come
on. If not, ask a Yamaha dealer to
check the electrical circuit.
3. Start the engine by pushing the
start switch. NOTICE: For maxi-
mum engine life, never acceler-
ate hard when the engine is
cold!
[ECA11041]
If the engine fails to start, release
the start switch, wait a few sec-
onds, and then try again. Each
starting attempt should be as short
as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one at-
tempt.
EAU16671
Shifting 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 il-
lustration.TIPTo 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 raise it.
NOTICE
ECA10260
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 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 the
shock of forced shifting.
