Notes for EFI Overhaul
Notes for EFI Overhaul
There are many precautions for overhau
l of EFI
system.
○This EFI system must be powered by a 12V battery.
Do not use any other battery as a power source for EFI
system.
○Do not connect the wrong battery cable, or ECU may
be damaged.
○To avoid damage to EFI parts, do not disconnect the
battery cable or any other electrical connectors while
the door lock is open or the engine is running.
○Be careful not to cause short-
circuit to the cable
directly connecting the positive (+) terminal of the
battery directly to the ground wire of frame.
○Disconnect the connecting wire between battery and
motorcycle, so as to prevent damaging ECU due to
high voltage.
○Close electric door lock before disconnecting EFI
electrical connection, and then disconnect battery (-).
Do not pull the lead, and only pull the connector.
Conversely, ensure that all EFI electrical connectors
have been connected before starting the engine.
○Plug-
in adapters should be bridged with power and
connected in place.
○D
o not open the door lock if any EFI electrical
connectors are not connected.
ECU will remember the fault code.
○Do not spill water on electrical parts, EFI parts,
connectors, leads and wires.
○If a motorcycle is equipped with a transceiver, make
sure that the radio wave sent from antenna will not
interfere with the operation of EFI system. Make the
engine in idling operation, and check the operation of
system. Keep the antenna as far away from ECU as
possible.
○Do not open electric door lock when disconnecting
any fuel pipe. Otherwise, the Fuel pump will run,
resulting in fuel discharged from the fuel pipe.
○Do not run after Fuel pump is completely dry, to
prevent Fuel pump from being stuck.
○Before disassembling parts of the fuel injection
system, blow out any dirt or dust outside the parts with
compressed air.
