Starting the engine
NOTICE
ECA10251
See page 7-5 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.
In order for the ignition circuit cut-off
system to enable starting, the sides-
tand must be up. (See page 5-30.) 1. With the smart key turned on, ap- proach the vehicle.
2. Push the “ON/ ” switch.
Upon authentication of the smart
key, the beeper will sound twice
and the centerstand and steering
locks (if applied) will be released.
All indicator and warning lights
should come on briefly and then go
off.
The ABS warning light should
come on when the power of the ve-
hicle is turned on, and go off once
the vehicle reaches a traveling
speed of 10 km/h (6 mi/h) or high-
er.
NOTICE
ECA22510
If a warning or indicator light does
not work as described above, see
page 5-2 for the corresponding warning and indicator light circuit
check.
3. Close the throttle completely.
4. Start the engine by pushing the “ON/ ” switch while applying the
front or rear brake.
If the engine does not start within 5
seconds of pressing the “ON/ ”
switch, wait 10 seconds before
pressing the switch again to allow
the battery voltage to restore.
NOTICE

For maximum engine life, never ac-
celerate hard when the engine is
cold!

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
Avoid high engine speeds during
acceleration.
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).
EAU16842
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.
EAU36532
0–1000 km (0–600 mi)
Avoid prolonged operation above 5100
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.
[ECA11283]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 6100
r/min.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE
ECA10311
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
Engine air filter and V-belt air filters This model’s engine air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with compressed air to avoid damaging
it.
The engine air filter element needs to be replaced and the V-belt air filter el- ements need to be serviced more frequent ly when riding in unusually wet or
dusty areas.
Hydraulic brake service After disassembling the brake master cylinders and calipers, always change the fluid. Regularly check the brake fluid levels and fill the reservoirs
as required.
Every two years replace the internal components of the brake master cylin- ders and calipers, and change the brake fluid.
Replace the brake hoses every four years and if cracked or damaged.

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.
Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification. Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
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. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible.
Specified spark plug:
NGK/CR7E
1. Spark plug gap
Spark plug gap:0.7–0.8 mm (0.028–0.031 in)
Tightening torque: Spark plug:

Canister
This model is equipped with a canister
to prevent the discharging of fuel vapor
into the atmosphere. Before operating
this vehicle, make sure to check the fol-
lowing:
Check each hose connection.
Check each hose and canister for
cracks or damage. Replace if dam-
aged.
Make sure that the canister breath-
er is not blocked, and if necessary,
clean it.
EAU77360
Engine oil and oil filter
cartridge
The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level 1. Place the vehicle on the center- stand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for two minutes, and then turn it off.
NOTICE
ECA11291
The engine must be cold before pro-
ceeding with the oil level check, oth-
erwise the check will result in a false
reading.
3. Wait two minutes until the oil set- tles, and then check the oil level
through the check window located
at the bottom-left side of the crank-
case.
TIP
The engine oil should be between the
minimum and maximum level marks.

of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter cartridge replace-
ment) 1. Place the vehicle on a level sur- face.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Place an oil pan under the engine to collect the used oil.
4. Remove the engine oil filler cap, the engine oil drain bolt and its
gasket to drain the oil from the
crankcase. 5. Check the O-ring for damage and
replace it if necessary.
TIP
Skip steps 6–8 if the oil filter cartridge is
not being replaced.
