Service Information
General Safety
●
Carry out inspection in sequence based on the troubleshooting table.
●
If the CDI unit is dropped, or if strong shock is applied thereto, CDI unit malfunction may result. Take due
precautions when handling it. Also, if the connector or coupler is connected or disconnected when there is
current flowing, overvoltage may occur on the unit leading to circuit damage. Always turn off the main
switch prior to servicing.
●
Ignition timing cannot be adjusted because the ignition system is of CDI type.
●
Spark plug check. (
3 - 5)
●
Connect the same color cords. Pay particular attention to colors prior to removing wiring. Connect the
same color couplers.
●
The resistance value may slightly differ from the standard values depending on each measuring situation.
