DFI Servicing Precautions (Kawasaki KLE 650 Versys)

0

There are a number of important precautions that should be followed servicing the DFI system.

• This DFI system is designed to be used with a 12 V sealed battery as its power source. Do not use any other battery except for a 12 V sealed battery as a power source.
• Do not reverse the battery cable connections. This will damage the ECU.
• To prevent damage to the DFI parts, do not disconnect the battery cables or any other electrical connections when the ignition switch is on or while the engine is running.
• Take care not to short the cables that are directly connected to the battery positive (+) terminal to the chassis ground.
• When charging, remove the battery from the motorcycle. This is to prevent ECU damage by excessive voltage.
• Do not turn the ignition switch ON while any of the DFI electrical connectors are disconnected. The ECU memorizes service codes.
• Do not spray water on the electrical parts, DFI parts, connectors, leads, and wiring.
• Whenever the DFI electrical connections are to be disconnected, first turn off the ignition switch, and disconnect the battery (-) terminal. Do not pull the lead, only the connector. Conversely, make sure that all the DFI electrical connections are firmly reconnected before starting the engine.
• Connect these connectors until they click [A].

If a transceiver is installed on the motorcycle, make sure that the operation of the DFI system is not influenced by electric wave radiated from the antenna. Check operation of the system with the engine at idle. Locate the antenna as far as possible away from the ECU.

• When any fuel hose is disconnected, fuel may spout out by residual pressure in the fuel line. Cover the hose joint with a piece of clean cloth to prevent fuel spillage.
• When any fuel hose is disconnected, do not turn on the ignition switch. Otherwise, the fuel pump will operate and fuel will spout from the fuel hose.
• Do not operate the fuel pump if the pump is completely dry. This is to prevent pump seizure.
• Before removing the fuel system parts, blow the outer surfaces of these parts clean with compressed air.
• To prevent corrosion and deposits in the fuel system, do not add to fuel any fuel antifreeze chemicals.
• To maintain the correct fuel/air mixture (F/A), there must be no inlet air leaks in the DFI system. Be sure to install the oil filler plug [A] after filling the engine oil.
• Clutch Cover [B]

Torque - Oil Filler Plug: Hand-tighten
