EAU00464
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.

Adjusting the carburetorsCarburetors, adjusting
The carburetors are important parts
of the engine and require very
sophisticated adjustment. Therefore,
most carburetor adjustments should
be left to a Yamaha dealer, who has
the necessary professional knowl-
edge and experience. The adjust-
ment described in the following sec-
tion, however, may be serviced by
the owner as part of routine mainte-
nance.
EC000095
cC
The carburetors have been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.
3. Check the engine idling speed
and, if necessary, adjust it to
specification by turning the throt-
tle stop screw. To increase the
engine idling speed, turn the
screw in direction a. To
decrease the engine idling
speed, turn the screw in direction

checked and, if necessary, adjusted
as follows at the intervals specified in
the periodic maintenance and lubrica-
tion chart.
The engine should be warm before
making this adjustment.
NOTE:

quickly responds to the throttle.
8A diagnostic tachometer is need-
ed to make this adjustment.
1. Remove panel B. (See page 6-7
for panel removal and installation
procedures.)

Headlight bulbs get very hot.
Therefore, keep flammable prod-
ucts away from a lit headlight bulb,
and do not touch the bulb until it
has cooled down.
3. Place a new bulb into position,
and then secure it with the bulb
holder.

TroubleshootingTroubleshooting
Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition sys-
tems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your scooter
require any repair, take it to a
Yamaha dealer, whose skilled techni-
cians have the necessary tools,
experience, and know-how to service
the scooter properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life
and can lead to expensive repair
bills.
EC000105
cC
Do not touch the glass part of the
headlight bulb to keep it free from
oil, otherwise the transparency of
the glass, the luminosity of the
bulb, and the bulb life will be
adversely affected. Thoroughly
clean off any dirt and fingerprints
on the headlight bulb using a cloth
moistened with alcohol or thinner.
4. Install the bulb cover, and then
connect the coupler.
5. Have a Yamaha dealer adjust
the headlight beam if necessary.
