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.) _
EW000044
WARNING
_ The motorcycle must not be ridden
with the sidestand down, or if the
sidestand cannot be properly
moved up (or does not stay up), oth-
erwise the sidestand could contact
the ground and distract the opera-
tor, resulting in a possible loss of
control. Yamaha’s ignition circuit
cut-off system has been designed to
assist the operator in fulfilling the
responsibility of raising the side-
stand before starting off. Therefore,
check this system regularly as de-
scribed below and have a Yamaha
dealer repair it if it does not function
properly. _

their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.

that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible loss
of control.

6-PERIODIC MAINTENANCE AND MINOR REPAIR
EAU00464
Safety is an obligation of the owner.
Periodic inspection, adjustment and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. The most important points of in-
spection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, DEPENDING ON THE
WEATHER, TERRAIN, GEOGRAPHI-
CAL LOCATION, AND INDIVIDUAL
USE, THE MAINTENANCE INTER-
VALS MAY NEED TO BE SHORT-
ENED.
