OPERATION AND IMPORTANT RIDING POINTS

EAU04755
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
letting it idle for an extended
length of time (e.g., in traffic jams,
at traffic lights or at railroad
crossings).
EAU01128
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1,600 km. 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
1,600 km. The various parts in the
engine wear and polish themselves to
the correct operating clearances.
During this period, prolonged full-
throttle operation or any condition that
might result in engine overheating must
be avoided.
EAU03845*
0 — 1,000 km
Avoid prolonged operation above 1/3
throttle.
1,000 — 1,600 km
Avoid prolonged operation above 1/2
throttle.
ECA00138
After 1,000 km of operation, be sure
to replace the engine oil and final
transmission oil.
1,600 km and beyond
The vehicle can now be operated
normally.
EC000049
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

with the spark plug wrench
included in the owner's tool kit.To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light
tan (the ideal color when the scoo-
ter is ridden normally).
NOTE :
If the spark plug shows a distinctly
different color, the engine could be
defective. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the scooter.
2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.
Specified spark plug:
DR8EA (NGK)To install the spark plug
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
Spark plug gap:
0.6 – 0.7 mm
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 specified torque.

•kg)
NOTE :
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
specified torque as soon as possible.
4. Install the spark plug cap.
5. Install the cowling.

Engine oil
The engine oil level should be checked
before each ride. In addition, the oil
must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the oil
change indicator comes on.To check the engine oil level
1. Place the scooter on the
centerstand.
NOTE :
Make sure that the scooter is positioned
straight up when checking the oil level.
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.

Coolant
The coolant reservoir is located under
the panel B. (See page 6-9 for panel
removal and installation procedures.)
To check the coolant level
1. Place the scooter on a level sur-
face and hold it in an upright posi-
tion.
NOTE :
•The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
•Make sure that the scooter is
positioned 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
coolant reservoir.
NOTE :
The coolant should be between the
minimum and maximum level marks.
1. Maximum level mark
2. Minimum level mark
3. If the coolant is at or below the
minimum level mark, remove the
reservoir cap, add coolant to the
maximum level mark, and then
install the reservoir cap.
