w● ●● ●
●
Become thoroughly familiar with
all operating controls and their
functions before riding. Consult
a Yamaha dealer regarding any
control or function that you do
not thoroughly understand.
● ●● ●
●
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.
● ●● ●
●
For safety, always start the en-
gine with the centerstand down.

cCSee page 5-3 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.1. Turn the key to “ON”.
ECAT1070
cCThe engine trouble warning light and
coolant temperature warning light
should come on for a few seconds,
then go off. If these warning lights
do not go off, have a Yamaha dealer
check their electrical circuits.2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the front
or rear brake.NOTE:
If the engine does not 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 5 seconds on any one
attempt. If the engine does not start with
the starter motor, try using the
kickstarter.
ECA11040
cCFor maximum engine life, never ac-
celerate hard when the engine is
