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.
EAUS1840
0–500 km (0–300 mi)
Avoid prolonged operation above
4000 r/min.
500–1000 km (300–600 mi)
Avoid prolonged operation above
6000 r/min. NOTICE: After 1000
km (600 mi) of operation, be
sure to replace the engine oil,
final transmission oil and the
oil filter element.
[ECA12931]
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.
EAU17213
Parking
When parking, stop the engine, and
then remove the key from the main
switch.
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.

TIP
Engine air filter and V-belt air filter
• This model’s engine air filter is equipped with a disposable oil-coated paper eleme\
nt, 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 element needs to be serviced more fre- quently when riding in unusually wet or dusty areas.
Hydraulic brake service
• After disassembling the brake master cylinders and calipers, always chan\
ge 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 th\
e bra- ke fluid.
• Replace the brake hoses every four years and if cracked or damaged.

EAU19622
Checking the spark plug
The spark plug is an important engine
component, which should be chec-
ked periodically, preferably by a
Yamaha dealer. Since heat and depo-
sits will cause any spark plug to
slowly erode, it 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.
The porcelain insulator around the
center electrode of the spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is ridden
normally). 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.
If the spark plug shows signs of elec-
trode erosion and excessive carbon
or other deposits, it should be repla-
ced.Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification.
1. Spark plug gap
Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)

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.
EAUS1701
Engine oil
The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the
service indicator light comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil
settles, remove the oil filler cap,
wipe the dipstick clean, insert it
back into the oil filler hole (wit-
hout screwing it in), and then
remove it again to check the oil
level.
TIP
The engine oil should be between the
minimum and maximum level marks.
1. Engine oil filler cap
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to rai-
se it to the correct level.
5. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
To change the engine oil (with or
without oil filter element
replacement)
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.

idle for several minutes while
checking it for oil leakage. If oil is
leaking, immediately turn the
engine off and check for the cau-
se.

TIP
If the engine oil is changed before the
oil change indicator comes on (i.e.
before 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 indica-
ted at the correct time. To reset the oil
change indicator before the periodic
oil change interval has been reached,
follow the above procedure, but note
that the indicator will come on for 1.4 seconds after releasing the “OIL

Final transmission oil
The final transmission case must be
checked for oil leakage before each
ride. If any leakage is found, have a
Yamaha dealer check and repair the
scooter. In addition, the final trans-
mission oil must be changed as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine, warm up the
final transmission oil by riding the
scooter for several minutes, and
then stop the engine.
2. Place the scooter on the centers-
tand.
3. Place an oil pan under the final
transmission case to collect the
