    SERVICE INFORMATION
    GENERAL INSTRUCTIONS
    · Check the ignition system according to the sequence specified in the Troubleshooting. ( 15-2)
    · The ignition system adopts CDI unit and the ignition timing cannot be adjusted.
    · If the timing is incorrect, inspect the CDI unit and A.C. generator and replace any faulty parts.
      Inspect the CDI unit with a CDI tester
    · Loose connector and poor wire connection are the main causes of faulty ignition system. Check
      each connector before operation.
    · Use of spark plug with improper heat range is the main cause of poor engine performance.
    · The inspections in this section are focused on maximum voltage. The inspection of ignition coil
      resistance is also described in this section.
    · Inspect the ignition switch according to the continuity table specified in page 17-3.
    · Inspect the spark plug referring to Section 3.
    · Remove the A.C. generator and pulser coil referring to Section 14.
