Since the kicker works through the clutch, you can usually free up a stuck clutch by pulling in the lever and kicking the bike multiple times. It may require lots of kicks, like 10 to 12 or more, but eventually this usually breaks the clutch free.
But as far as starting the bike goes, I don't think you'll have any luck until you figure out your lack of power issue. Time to start tracing power and checking fuses. Here's a simplified drawing showing the power path and fuses .....
It's also possible that the ignition switch itself is at fault, all dirty and crusty inside and not allowing power to pass through.
