9-20 ELECTRICAL SYSTEM
IGNITION SYSTEM
NOTE:
The fuel cut-off circuit is incorporated in this ECM in order to prevent over-running of engine. When engine
speed reaches 15 500 r/min, this circuit cuts off fuel at the fuel injector. But under no load, the clutch lever is
pulled or the gear position is neutral, this circuit cuts off fuel when engine speed reaches 15 100 r/min.
E-03, 24, 33: The circuit cuts off the ignition primary current for all spark plugs.
Under no load, the engine can run over 15 100 r/min though the ignition cut-off circuit is effec-
tive, which may possibly cause engine damage. Do not run the engine without load over 15 100
r/min at anytime.
