What causes no spark on a motorcycle?
If you are having a no-spark problem, a good place to start after ruling out shorts, grounds, switches and spark plugs, is the ignition coil, spark plug caps and wires. A breakdown in the insulation can cause arcing in the plug wire. You will be able to see the wire spark in low light conditions.
