Information Summary and Preparation -1
2) Directions during maintenance
1. Do not arbitrarily remove any part or connector of the Electronic Management System from
its initial position; avoid any accidental damage or foreign object such as water and greasy
dirt to enter into any connector and affect a properly running Electronic Management
System.
2. In order to prevent any electrical device from damage, the power supply shall be
disconnected prior to a connector removed or connected.
3. During any operation to simulate the thermal state of one defective unit or increase
temperatures, the temperature of the electronic control unit shall be less than 80 degrees
Celsius.
4. All fuel hoses shall be high pressure-tolerant pipes in virtue of the high fuel pressure in the
Electronic Management System (300kPa or so) or even at the engine stopped. As a result,
the fuel hose during maintenance shall not be disassembled arbitrarily. In the case of
maintaining the fuel system, the pressure in the fuel system shall be released prior to
removal of a fuel hose shown as follows: Remove the fuel pump relay; start the engine; keep
the engine at the idle speed until the engine stops. The operation of removal of a fuel hose
and replacement of a clamp shall be executed by a professional mechanic in a
well-ventilated place.
5. The power supplied to the electric fuel pump which is being removed from the fuel tank
shall be disconnected beforehand to prevent any spark or fire.
6. The fuel pump to be tested shall not be empty or refilled by water or the service life will be
curtailed. On the other hand, the positive and negative poles of the fuel pump shall be
properly connected.
7. Unless otherwise required, the spark test shall not be conducted or be completed quickly
during inspections of the ignition system. Additionally, the air throttle shall be kept closed
during inspections or the incompletely ignited gasoline will be fed into the exhauster and
damage the three-way catalytic converter.
8. The idle speed has been adjusted by the Electronic Management System in advance and not
changed manually. The initial position of the throttle stop screw adjusted by Motive Power
shall not be changed by a user without permission unless otherwise demanded.
9. The cables to be connected to the positive and negative poles on a battery shall be correctly
linked or the electronic devices will be damaged. The minus earth is used in the system.
10. Any cable connected to a battery shall not be disconnected during the engine running.
11. The battery shall be removed from the motorcycle for a charge separately conducted but not
be directly charged with the battery fixed on the vehicle for convenience.
12. The cables connected to the battery’s positive & negative poles and the electronic control
unit shall be removed from the motorcycle prior to any electrical welding operation.
13. Do not cut a cable’s cover layer to test any signal imported to or exported from one device.
