Throttle override system
(T.O.R.S.)
EWS00042
WARNING
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 (RST90TF / RST90TFL / RST90TFY)
or ignition (RST90) and limit the engine speed
to less than the clutch engagement speed if
the throttle valves fail to return to the idle po-
sition when the throttle lever is released. (See
page 110 for the clutch engagement speed.)
