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.

adjusted in accordance with the engine
speed by a computer-controlled servo-
motor.
NOTICE
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.
TIP
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
