[QUOTE="sharky243, post: 1325611, member: 100273"] Start by replacing the spark plug. Disconnect the the kill switch wire. Inspect the wiring harness for bare, shorted or broken wires. Check all ground connections. Inspect the generator coils, and the trigger coil for damage. These are under the flywheel on the stator. Check the resistance of the coils and compare them to Honda specs. These specs can be found in any good service manual for your bike. Check the flywheel key to see if it sheared when the nut came loose. Check the magnets on the flywheel to make sure they are good and strong. Check the resistances of the primary and secondary windings of the main ignition coil, the specs should be in the book. Check the high tenssion lead and the spark plug cap. Some spark plug caps have resisters in them. If all of these components check out good with no shorts or broken circuits, try another CDI module. [/QUOTE]
