If you have 12v to the coil, you might have a bad coil. I had one go out on me and did it like you are talking, Started missing intermittently and running like ****, and then only one cylinder. I limped into a harley dealer, loosened up the tank enough to get the bolts and installed the new one.
Back to normal...

I thought cam position sensors were only on the EFI bikes. OP says he's running a carb.
Btw. If you can charge the battery up and the bike starts, I'd lean towards a bad battery or a charging system not working right. Could just be connections as well.

The cam position sensor, or "pick up" is in nose cone, all bikes with electronic ignitions need them to tell the ign module to sent the signal at the proper time. Crankshaft position sensors are on EFI bikes.

Brown goo...... you found the problem. Replace the pickup. If you want to verify, run it until it fails (heat does it) then hit it with some freeze spray (radio shack) and see if it wakes back up. If so, it's bad.

If you want to test it you can take off your nose cone cover then start your bike and heat the cam position sensor with a hair dryer or heat gun.
If you see goo bubbling or the bike shuts off you know the cam position sensor is bad.
