Control functions
Be sure to use the specified spark plug
G
and spark plug cap. Otherwise, the
T.O.R.S. will not work properly.
If the throttle bodies or throttle cable malfunc-
tions during operation, the T.O.R.S. will oper-
ate when the throttle lever is released.
The T.O.R.S. is designed to override the fuel
injection and limit the engine speed to less
than the clutch engagement speed if the throt-
tle valves fail to return to the idle position
when the throttle lever is released. (See page
74 for the clutch engagement speed.)
