Since you know the battery is bad I would just throw a new one in and then check the voltage going to the battery with a voltmeter. With the bike off you should get a reading around 12.6 volts, with the bike running it should be around 13.2 to 14 volts i think. If you get a good reading then chances are you did not mess anything up.

One of the things I have done when the battery was discharged,was to use a regular household extension cord to connect to a car battery. I think the resistance of the small wires kept the electronics of the bike from being damaged. I pulled them apart to ensure I didnt mix them at the terminals. It was an emergency 'fix' that worked. Anybody have thoughts on this in a pinch?

If you get it running, then you're no longer using the battery whatsoever. If it's dying AFTER you get it started, your problem is far bigger than just a battery.
First and foremost, pop off your tail fairing and see if the R\R is melted. If it LOOKS ok, start testing it:

A bad R\R can cause exactly this symptom, AND totally destroy a battery beyond charging. If your R\R IS bad, replace it with a nice one from a GSXR or R6. Don't stick another junk Honda one on there.
