Main switch/steering lock
The main switch/steering lock controls
the ignition and lighting systems, and
is used to lock the steering. The
various positions are described below.
EAU34121
ON “f”
All electrical circuits are supplied with
power; the meter lighting, taillight,
license plate light and auxiliary lights
come on, and the engine can be star-
ted. The key cannot be removed.
NOTE:
The headlights come on automatically
when the engine is started and stay
on until the key is turned to "OFF" or
the sidestand is moved down.
EAU10660
OFF “e”
All electrical systems are off. The key
can be removed.
EAUM1020
“h”
The coolant temperature warning light
should come on when the key is tur-
ned to “
h”. (See page 3-2.)
EAU10680
LOCK “m”
The steering is locked, and all electri-
cal systems are off. The key can be
removed.

Adjusting the shock
absorber assemblies
1. Spring preload adjusting ring
2. Position indicator
Each shock absorber assembly is
equipped with a spring preload adjus-
ting ring.
ECA10100
CAUTION:
Never attempt to turn an adjusting
mechanism beyond the maximum
or minimum settings.
EWA10210
s s
WARNING
Always adjust both shock absorber
assemblies equally, otherwise poor
handling and loss of stability may
result.
Adjust the spring preload as follows.
To increase the spring preload and
thereby harden the suspension, turn
the adjusting ring on each shock
absorber assembly in direction (a). To
decrease the spring preload and the-
reby soften the suspension, turn the
adjusting ring on each shock absor-
ber assembly in direction (b).
NOTE:
Align the appropriate notch in the
adjusting ring with the position indica-
tor on the shock absorber.
EAU15301
Sidestand
1. Sidestand switch
2. Sidestand
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the motorcycle upright.
NOTE:
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain
situations. (See further down for an
explanation of the ignition circuit cut-
off system.)

WARNING
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control. Yama-
ha’s ignition circuit cut-off system
has been designed to assist the
operator in fulfilling the responsibi-
lity of raising the sidestand before
starting off. Therefore, check this
system regularly as described
below and have a Yamaha dealer
repair it if it does not function pro-
perly.
EAU15361
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
It prevents starting when the
sidestand is up, but neither brake
is applied.
It prevents starting when either
brake is applied, but the sides-
tand is still down.
It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.
EWA10260
s s
WARNING
The vehicle must be placed on
the centerstand during this ins-
pection.
If a malfunction is noted, have
a Yamaha dealer check the
system before riding.

Troubleshooting
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 technicians
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.
