EAU15596
Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always follow the ins-
pection and maintenance procedures and schedules described in the Owner’s Manual.
EWA11151
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment dama-
ge. Do not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures pro-
vided in this manual, have the vehicle inspected by a Yamaha dealer.
Before using this vehicle, check the following points:

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!

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.

Parking
When parking, stop the engine, remo-
ve the key from the main switch, and
then turn the fuel cock lever to “OFF”.
EWA10311
Since the engine and exhaust
system can become very hot,
park in a place where pedes-
trians or children are not likely
to touch them and be burned.
Do not park on a slope or on
soft ground, otherwise the
vehicle may overturn, increa-
sing the risk of a fuel leak and
fire.
Do not park near grass or other
flammable materials which
might catch fire.

TIP
The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK,
a mileage-based maintenance, is performed instead.
From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.

Checking the spark plug
The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause
any spark plug to slowly erode, the
spark plug should be removed and
checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
To remove the spark plug1. Remove panel A. (See page 6-8).
2. Remove the spark plug cap.

Troubleshooting
Although Yamaha motorcycles recei-
ve a thorough inspection before ship-
ment from the factory, trouble may
occur during operation. Any problem
in the fuel, compression, or ignition
systems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your motorcy-
cle require any repair, take it to a
Yamaha dealer, whose skilled techni-
cians have the necessary tools, expe-
rience, and know-how to service the
motorcycle properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
EWA15141
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
area, including pilot lights from
water heaters or furnaces. Gasoli-
ne or gasoline vapors can ignite or
explode, causing severe injury or
property damage.
