Engine break-inThere 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 follow-
ing 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 themselves
to the correct operating clearances. Dur-
ing this period, prolonged full-throttle
operation or any condition that might
result in engine overheating must be
avoided. Fuel consumption, tips for reducing
Engine break-in
EAU16820
Tips for reducing fuel con-
sumptionFuel 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 traf-
fic lights or at railroad crossings).
EAU16951
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 five 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.
Rev the engine freely through the gears,
but do not use full throttle at any time.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above 3/4
throttle.
NOTICE:
After 1000 km (600
mi) of operation, the engine oil must
be changed and the oil strainer
cleaned.
[ECA10351]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.
ECA10270
NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

To install the spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.Spark plug gap:
0.7 ~ 0.8 mm (0.028 ~ 0.031 in)2. Clean the surface of the spark plug
gasket and its mating surface, 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 specified torque.Tightening torque:
Spark plug:
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 plugshould be tightened to the specified
torque as soon as possible.
4. Install the spark plug cap.
5. Install the panel.

Engine oilThe engine oil level should be checked
before each ride. In addition, the oil must
be changed and the oil strainer cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
To check the engine oil level
1. Place the vehicle on the
centerstand. A slight tilt to the side
can result in a false reading.
2. Start the engine, warm it up for sev-
eral minutes, and then turn it off.ZAUM00**

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 (without
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.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.
5. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
To change the engine oil
1. Start the engine, warm it up for sev-
eral 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 bolt to drain the
oil from the crankcase.

it for oil leakage. If oil is leaking,
immediately turn the engine off and
check for the cause.
7. Turn the engine off, and then check
the oil level and correct it if neces-
sary. Final transmission oil
EAUT1561
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 final transmission oil must
be changed as follows at the intervals
specified in the periodic maintenance
and lubrication chart.
1. Start the engine, warm it up by
riding the scooter for several min-
utes, and then stop the engine.
2. Place the scooter on the
centerstand.
3. Place an oil pan under the final
transmission case to collect the
used oil.

EAUT1523
To check the coolant level
The coolant level should be checked as
follows before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
1. Place the vehicle on the
centerstand.TIP
8The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
8Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.TIP
The coolant should be between the mini-
mum and maximum level marks.ZAUM00**
