WARNING
EWA10270


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 lossof control.
EAU37640
Starting and warming up a
cold engine 1. Turn the key to “ON”.
2. 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.
3. Place the vehicle on the center-
stand.
WARNING
EWA14200
Before starting the engine, make
sure the transmission is in neutral
and that the vehicle is placed on thecenterstand.
4. Turn the starter (choke) on and
completely close the throttle. (See
page 3-7.)
5. Start the engine by pushing the
start switch or by pushing the kick-
starter lever down.
NOTE:If the engine fails to start by pushing the
start switch, release the switch, wait a
few seconds, and then try again. Each
starting attempt should be as short as
possible to preserve the battery. Do not
crank the engine more than 10 seconds
on any one attempt. If the engine does
not start with the starter motor, try usingthe kickstarter.CAUTION:
ECA15170
The coolant temperature warning
light should come on when the key
is turned to “ON”, and then go off af-
ter a few seconds. If the coolant tem-
perature warning light comes on
after starting, immediately stop the
engine, and have a Yamaha dealercheck the electrical circuit.
6. After starting the engine, move the
starter (choke) back halfway.

For maximum engine life, always
warm the engine up before starting
off. Never accelerate hard when theengine 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 start-
ing a cold engine with the exception
that the starter (choke) is not required
when the engine is warm.
EAU37550
Shifting Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing hills,
etc. When shifting gears, fully return the
throttle grip. The use of the shift pedal
is shown in the illustration.NOTE:The transmission cannot be shifted
from 4th gear to neutral when the en-gine is running.CAUTION:

Make sure that the transmission
is completely shifted into gear.

Tips for reducing fuel
consumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Turn the starter (choke) off as
soon as possible.


Shift up swiftly, and avoid high en-
gine speeds during acceleration.


Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.


Turn the engine off instead of let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
EAU16830
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.

5Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for five to ten
minutes.
Vary the engine speed from time to
time. Do not operate the engine at one
set throttle position.
150–500 km (90–300 mi)
Avoid prolonged operation above 1/2
throttle.
Rev the engine freely through the
gears, but do not use full throttle at any
time.500–1000 km (300–600 mi)
Avoid prolonged operation above 3/4
throttle.
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the engine speed occasionally.
CAUTION:
ECA10361


After 1000 km (600 mi) of opera-
tion, the engine oil must be
changed, the oil filter cartridge
or element replaced, and the oil
strainer cleaned.


If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-cle.
