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.
EWA10271
Failure to familiarize yourself with
the controls can lead to loss of
control, which could cause an acci-
dent or injury.
EAU16055
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.
See page 3-14 for more information. 1. Turn the fuel cock lever to “ON”.
2. Turn the key to “ ” and make sure that the engine stop switch
is set to “ ”.
3. Shift the transmission into the neutral position. The neutral indi-
cator light should come on. If not,
ask a Yamaha dealer to check the
electrical circuit.
4. Turn the starter (choke) on and completely close the throttle.
(See page 3-12).
5. Start the engine by pushing the start switch.
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 preserve
the battery. Do not crank the
engine more than 10 seconds on
any one attempt.
6. After starting the engine, move the starter (choke) back halfway.
7. When the engine is warm, turn the starter (choke) off.
TIP
The engine is warm when it responds
quickly to the throttle with the starter
(choke) turned off.
ECA11042
For maximum engine life, never
accelerate hard when the engine is
cold!

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. Neutral position
2. 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.
TIP
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.
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
distances. 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 dama-
ging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
Turn the starter (choke) off as
soon as possible.
Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
Do not rev the engine while shif-
ting down, and avoid high engine
speeds with no load on the engi-
ne.
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 cros-
sings).
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 following 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 themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAUS1560
0–500 km (0–300 mi)
Avoid prolonged operation above
4000 r/min.
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 engi-
ne at one set throttle position.500–1000 km (300–600 mi)
Avoid prolonged operation above
6000 r/min.
Rev the engine freely through the
gears, but do not use full throttle
at any time.
NOTICE:After 1000
km (600 mi) of operation, the
transmission oil must be chan-
ged.
[ECA10370]
1000 km (600 mi) and beyond
The vehicle can now be operated
normally.
ECA10310
Keep the engine speed out of
the tachometer red zone.
If any engine trouble should
occur during the engine break-
in period, immediately have a
Yamaha dealer check the vehi-
cle.

3. Remove the spark plug asshown, using the spark plug
wrench, which is located in the
storage compartment. (See page
6-1).
1. Spark plug wrench
To check the spark plug1. Check that the porcelain insula- tor around the center electrode of
the spark plug is a medium-to-
light tan (the ideal color when the
vehicle is ridden normally).
TIP
If the spark plug shows a distinctly
different color, the engine could be
operating improperly. Do not attempt
to diagnose such problems yourself. Instead, have a Yamaha dealer check
the vehicle.
2. Check the spark plug for electro-
de erosion and excessive carbon
or other deposits, and replace it if
necessary.
To install the spark plug 1. Measure the spark plug gap with a wire thickness gauge and, if
necessary, adjust the gap to spe-
cification.
1. Spark plug gap
2. Clean the surface of the sparkplug gasket and its mating surfa-
ce, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the spark plug wrench, and then
tighten it to the specified torque.
TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4–1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
4. Install the spark plug cap.
5. Install the panel.
Tightening torque:Spark plug: 22.5 Nm (2.2 m•kgf, 16.3 ft•lbf)
Spark plug gap:0.6–0.7 mm (0.024–0.028 in)
