No or Intermittent High Tension Voltage
● Faulty Ignition coil
3.11.3 CDI INSPECTION
Remove the three screws from the battery case cover.
Disconnect the CDI module from the wire harness
Test resistance of the terminals with an multi-meter.
● Since there is semiconductor in return circuit, testing
result may be significantly different if different multi-meter
are used.
● If the pointer on the dial flickers and finally stops at ∞in
testing, it should be regarded as normal. Because the
capacitor in the CDI module is charged while being tested
and it cannot discharge at this time.
3.11.4 IGNITION COIL
Removal Steps
Remove the middle box.
Remove the spark plug cap.
Disconnect the wires, remove ignition coil
