ESU13751
Throttle override system
(T.O.R.S.)
WARNING
EWS00042
If the T.O.R.S. is activated, make sure that
the cause of the malfunction has been
corrected and that the engine can be op-
erated without a problem before restarting
the engine. Continuing to operate with a
malfunction could cause loss of control or
damage.
If the throttle valves or throttle cable malfunc-
tions during operation, the T.O.R.S. will be
activated when the throttle lever is released.
The T.O.R.S. is designed to override the fuel
injection (RST1NTF / RST1NTFY) or ignition
(RST9N) and limit the engine speed to less
than the clutch engagement speed if the
throttle valves fail to return to the idle position
when the throttle lever is released. (See page
110 for the clutch engagement speed.)
TIP
If the T.O.R.S. is activated, the warning light
and engine trouble warning indicator flash,
and the two-digit code “84” displays
(RST1NTF / RST1NTFY) or flashes (RST9N)
in the meter display. If this occurs, have a
Yamaha dealer check the system as soon as
possible.
