switch and neutral switch) has the fol-
lowing functions.●
It prevents starting when the trans-
mission is in gear and the side-
stand is up, but the clutch lever is
not pulled.

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

Refuel if necessary.
Check fuel line for leakage.
Check fuel tank breather hose and overflow
hose for obstructions, cracks or dam-
age, and check hose connections. 3-16, 3-17
Engine oil Check oil level in engine.
If necessary, add recommended oil to specified level.
Check vehicle for oil leakage. 6-11
Coolant Check coolant level in reservoir.
If necessary, add recommended coolant to specified level.
Check cooling system for leakage. 6-14
Front brake Check operation.
If soft or spongy, have Yamaha dealer bleed hydraulic system.
Check brake pads for wear.
Replace if necessary.
Check fluid level in reservoir.
If necessary, add specified brake fluid to specified level.

NOTICE
ECA11833
If a warning or indicator light does
not come on initially when the key is
turned to “ON”, or if a warning or in-
dicator light remains on, see page
3-4 for the corresponding warning
and indicator light circuit check.2. Shift the transmission into the neu-tral position. The neutral indicator
light should come on. If not, ask a
Yamaha dealer to check the elec-
trical circuit.
3. Start the engine by pushing the start switch.
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.NOTICE
ECA11042
For maximum engine life, never ac-
celerate hard when the engine is
cold!

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.

Tips for reducing fuel con-
sumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:●
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).
EAU16841
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 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
1600 km (1000 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.
EAU17093
0–1000 km (0–600 mi)
Avoid prolonged operation above 5800
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil must
be changed and the oil filter car-
tridge or element replaced.
[ECA10302]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 7000
r/min. 1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE
ECA10310
●
Keep the engine speed out of
the tachometer red zone.
●
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi- cle.

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 50000 km (30000 mi), repeat the maintenance intervals starting from 10000 km (6000 mi).
●
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technical
skills.

EAU19642
Checking the spark plugs The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.
