Instead of riding the bike one handed try suspending the rear wheel and spinning it with the plug out, wire connected to it and the plug grounded against the engine. The clutch will need to be engaged too.
I'm sure CT knows this but I added it for the benefit of a newbie who might read this and not understand how to check for ignition.
