Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the fol-
lowing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING
ON THE WEATHER, TERRAIN,
GEOGRAPHICAL LOCATION, AND
INDIVIDUAL USE, THE MAINTE-
NANCE INTERVALS MAY NEED TO
BE SHORTENED.

wIf you are not familiar with scooter
maintenance work, have a Yamaha
dealer do it for you.

wThis scooter is designed for use
on paved roads only. If this scoot-
er is operated in abnormally dusty,
muddy or wet conditions, the air
filter element should be cleaned or
replaced more frequently, other-
wise rapid engine wear may result.
Consult a Yamaha dealer for prop-
er maintenance intervals.

Owner’s tool kitThe owner’s tool kit is located under
the seat. (See page 3-9 for seat
opening and closing procedures.)
The service information included in
this manual and the tools provided in
the owner’s tool kit are intended to
assist you in the performance of pre-
ventive maintenance and minor
repairs. However, additional tools
such as a torque wrench may be nec-
essary to perform certain mainte-
nance work correctly.

9To check the spark plugs
1. Check that the porcelain insula-
tor around the center electrode
on each spark plug is a medium-
to-light tan (the ideal color when
the scooter is ridden normally).
2. Check that all spark plugs
installed in the engine have the
same color.
NOTE:
If any 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.3. Check each spark plug for elec-
trode erosion and excessive car-
bon or other deposits, and
replace it if necessary.To install a spark plug
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
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.4. Install the spark plug cap.

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 drain bolt to drain the oil
from the crankcase.
NOTE:
Skip steps 4–6 if the oil filter cartridge
is not being replaced.
4. Remove the oil filter cartridge
with an oil filter wrench.NOTE:
An oil filter wrench is available at a
Yamaha dealer.5. Apply a thin coat of engine oil to
the O-ring of the new oil filter
cartridge.NOTE:
Make sure that the O-ring is properly
seated.

Chain drive oilThe chain drive oil should be
changed as follows at the intervals
specified in the periodic maintenance
and lubrication chart.
1. Remove panel F. (See page 6-8
for panel removal and installation
procedures.)
2. Place an oil pan under the chain
drive case to collect the used oil.
3. Remove the oil filler cap and
drain bolt to drain the oil from the
chain drive case.4. Install the chain drive oil drain
bolt, and then tighten it to the
specified torque.
5. Add the specified amount of the
recommended oil.
6. Wipe the dipstick clean, insert it
into the oil filler hole (without
screwing it in), and then remove
it to check the oil level.

Checking the brake fluid
levelInsufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low
brake fluid level may indicate worn
brake pads and/or brake system
leakage. If the brake level is low, be
sure to check the brake pads for
wear and the brake system for leak-
age.1. Minimum level mark

Rear brake pads
1. Remove the rear brake caliper
by removing the bolts.
2. Check each rear brake pad for
damage and measure the lining
thickness. If a brake pad is dam-
aged or if the lining thickness is
less than 0.8 mm, have a
Yamaha dealer replace the
brake pads as a set.
3. Install the rear brake caliper by
installing the bolts, then tighten-
ing them to the specified torque.1. Bolt (×2)
