EXUP system

This model is equipped with Yamaha's
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that regu-
lates the diameter of the exhaust pipe.
The EXUP system valve is constantly
adjusted in accordance with the engine
speed by a computer-controlled servo-
motor.
CAUTION:
G The EXUP system has been set
and extensively tested at the
Yamaha factory.
these settings without sufficient
technical knowledge may result
in poor performance of or dam-
age to the engine.
G If the EXUP system cannot be
heard when the main switch is
turned on, have a Yamaha deal-
er check it.

Sidestand

The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle 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
ECA10191
the ignition circuit cut-off system.)
Changing
The vehicle must not be ridden with
the sidestand down, or if the side-
stand 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.
Yamaha's ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly as described
