Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in the
safest and most efficient condition pos-
sible. The most important points of ins-
pection, adjustment, and lubrication are
explained on the following pages.
The intervals given in the periodic main-
tenance and lubrication chart should be
simply considered as a general guide
under normal riding conditions. However,
DEPENDING ON THE WEATHER,
TERRAIN, GEOGRAPHICAL LOCA-
TION, AND INDIVIDUAL USE, THE
MAINTENANCE INTERVALS MAY
NEED TO BE SHORTENED.

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.

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.
