is constantly adjusted in accordance
with the engine speed by a computer-
controlled servomotor.

and extensively tested at the
Yamaha factory.

technical knowledge may result
in poor performance of or dam-
age to the engine.

erate, have a Yamaha dealer

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 motorcycle must not be ridden
with the sidestand down, or if the
sidestand
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.
