3. Start the engine by pushing the
start switch while applying the front
or rear brake.
If the engine does not start, re-
lease the start switch, wait a few
seconds, 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.

Starting off
1. While pulling the rear brake lever
with your left hand and holding the
grab bar with your right hand, push
the scooter off the centerstand.
2. Sit astride the seat, and then ad-
just the rear view mirrors.
3. Switch the turn signals on.
4. Check for oncoming traffic, and
then slowly turn the throttle grip (on
the right) in order to take off.
5. Switch the turn signals off.

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.
EAU36531
0–1000 km (0–600 mi)
Avoid prolonged operation above
4000 r/min.
NOTICE:
After 1000 km
(600 mi) of operation, the engine oil
must be changed, and the oil filter
cartridge or element replaced.

[ECA11282]

1000–1600 km (600–1000 mi)
Avoid prolonged operation above
6000 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.
EAU17213
Parking
When parking, stop the engine, and
then remove the key from the main
switch.
WARNING

EWA10311

Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans 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, increasing 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 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.

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 elements 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 cylinders and calipers, and change the brake
fluid.
• Replace the brake hoses every four years and if cracked or damaged.

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.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)

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

ECA11290
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.
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
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 forseveral 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.

TIP

Skip steps 6–8 if the oil filter cartridge is
not being replaced.
6. Remove the oil filter cartridge with
an oil filter wrench.
TIP

An oil filter wrench is available at a
Yamaha dealer.
7. Apply a thin coat of clean engine
oil to the O-ring of the new oil filter
cartridge.

11. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
12. Turn the engine off, and then
check the oil level and correct it if
necessary.
13. Reset the oil change indicator.
(See page 3-9.)
TIP

If the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the periodic oil change interval has
been reached), the indicator must be
reset after the oil change for the next
periodic oil change to be indicated at
the correct time.
EAU19997
Chain drive oil
The chain drive oil should be changed
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
1. Place the vehicle on a level sur-
face.
2. Remove panel E. (See page 6-7.)
3. Place an oil pan under the chain
drive case to collect the used oil.
4. Remove the chain drive oil filler
cap, the chain drive oil drain bolt
and its gasket to drain the oil from
the chain drive case.5. Install the chain drive oil drain bolt
and its new gasket, and then tight-
en the bolt to the specified torque.
6. Refill with the specified amount of
the recommended oil.
7. Wipe the dipstick clean, insert it
into the oil filler hole (without
screwing it in), and then remove it
to check the oil level.
TIP

The chain drive oil should be between
the tip of the dipstick and the maximum
level mark.
