So both sides don't have spark(assuming you've tried different spark plugs, and check all your electrical connectors, etc.). Start by checking all your grounds and connectors makeing sure you have good solid connections w/no broken wires. Then proceed to test your stator, coil, and pickup coil to see if resistance values are within your Clymer Manuals specs. If you don't find anything bad in your testing, test your kill switch and key switch. Still haven't found anything wrong, move on to testing your wiring harness. If continuity is good throughout the ignition portion of the harness, it then becomes a guessing game Can't test the CDI, and everything else tests good, start replacing your components cheapest to most expensive. If you have the option of obtaining spare or borrowed parts, test the components this way. I have never seen TORS cause a no spark condition, but if you want to eliminate that as a possibility unplug the control box. Good luck!
