1. Spark Plug:
- Check the condition of the spark plug. Look for any damage or excessive wear. Clean or replace the spark plug as needed.
2. Spark Plug Cap:
- Ensure that the spark plug cap is properly attached to the spark plug. Check the condition of the cap and the wire, replacing if necessary.
3. Ignition Coil:
- Check the ignition coil. Look for any visible damage or cracks. Disconnect the coil from the spark plug cap and measure its resistance using a multimeter. Compare it with the manufacturer's specifications and replace the coil if necessary.
4. High Tension Lead:
- Disconnect the HT (High Tension) lead and inspect it for damage. Ensure the lead is properly connected on both ends.
5. Kill Switch:
- Make sure the kill switch is in the "Run" position. Check the kill switch circuit, paying attention to the contacts. Clean any corrosion and repair or replace the components as needed.
6. Flywheel Sensor:
- Check the flywheel sensor, paying attention to its location and the air gap. Clean or repair the sensor as needed.
7. Check stator:
- If the steps above don't solve the problem, the stator may be the cause of the spark issue. Check the stator windings resistance using a multimeter and compare them with the manufacturer's specifications. Replace the stator if the resistance is significantly different from the recommended values.
8. Check the wiring:
- Check all wiring connections, especially the ones around the ignition components. Make sure there are no loose or broken wires. If necessary, repair or replace the wiring.
While troubleshooting, it is recommended to use a multimeter to measure resistance, voltage and continuity. If you are not familiar with electrical troubleshooting, it may be best to consult a qualified motorcycle mechanic for assistance.
