A simple test:
Remove the spark plug from the engine, reconnect the plug wire to it and lay the plug against the cylinder head cooling fins making sure the metal part (where you put the wrench) of the plug is firm against the fins. Leave the clutch lever released, clutch engaged, and push the bike forward at a good pace while watching the plug. If the ignition system is working you'll see a spark at the plug's electrodes (the little 'L' shaped thing at the end and the one protruding from the center.) It's an awkward process but if you have a way to suspend the rear wheel you can also spin the pedals to rotate the engine's crankshaft.
