OPERATION AND IMPORTANT RIDING POINTS
EAU16820
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing 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 cross-
ings).
EAU16830
Engine break-inThere is never a more important pe-
riod 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 fi rst
1000 km (600 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheating
must be avoided.
EAUT3540
0 ~ 150 km (0 ~ 90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for fi ve to
ten minutes.
Vary the engine speed from time to
time. Do not operate the engine at
one set throttle position.
150 ~ 500 km (90 ~ 300 mi)
Avoid prolonged operation above 1/2
throttle.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above
3/4 throttle.
NOTICE:
After 1000
km (600 mi) of operation, be sure
to change the engine oil and final
transmission oil, and to clean the
oil strainer.
[ECA16501]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the engine speed occasionally.
ECA10270
NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

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.

1. Spark plug wrenchTo check the spark plug
1. Check that the porcelain insula-
tor around the center electrode
of the spark plug is a medium-to-
light tan (the ideal color when the
vehicle is ridden normally).TIPIf 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.
2. Check the spark plug for elec-trode erosion and excessive
carbon or other deposits, and re-
place it if necessary.
Speci ed spark plug:
CPR9EA-9 (NGK)To install the spark plug
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specifi cation.Spark plug gap:
0.8 ~ 0.9 mm (0.031 ~ 0.035 in)2. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then
tighten it to the specifi ed torque.Tightening torque:
Spark plug:
13 Nm (1.3 m·kgf, 9.4 ft·lbf)
EAUT1835
Checking the spark plugThe 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 pe-
riodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
To remove the spark plug
1. Place the vehicle on the center-
stand.
2. Remove panel C. (See page 6-8.)
3. Remove the spark plug cap.
4. Remove the spark plug as
shown, with the spark plug
wrench included in the owner’s
tool kit.

Engine oil and oil strainerThe engine oil level should be
checked before each ride. In addition,
the oil must be changed and the oil
strainer cleaned at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the scooter on the center-
stand. 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 fi ller hole (without
screwing it in), and then remove it
again to check the oil level.TIPThe engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is below the mini-
mum level mark, add suffi cient oil
of the recommended type to raise
it to the correct level.
5. Insert the dipstick into the oil fi ller
hole, and then tighten the oil fi ller
cap.
To change the engine oil and clean
the oil strainer
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.
3. Remove the engine oil filler cap
and the engine oil drain bolts A
TIPIf 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 fi nger tight. However, the
spark plug should be tightened to the
specifi ed torque as soon as possible.
4. Install the spark plug cap.
5. Install the panel.

Final transmission oilThe 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 fi nal transmis-
sion oil must be changed as follows at
the intervals specified in the periodic
maintenance and lubrication chart.
1. Start the engine, warm up the fi -
nal transmission oil by riding the
scooter for several minutes, and

10. Turn the engine off, and then
check the oil level and correct it if
necessary.
