Need some diagnostic help.....
Just suggesting that you make sure the battery is charged up, maybe take it out and down to the dealer. Mine would charge and test it for free. And then before putting it back in go over every thing that could have picked up any moisture, even off the road and make sure it's all dried out. I think one of the guys mentioned PC (electronic ignition) would make the bike pop if it got wet, ... anything with water and electrics = NFG.

Testing things for water, if you have an air compressor try blowing some air into the switch housings, connectors, back side of the electrical caddy, etc. If you don't have a ready source of dry air, try buying one of those compressed air cans from FRYs or some computer sales place. Some connectors are easily unplugged and shaken, don't need air.
If you see any water, suspect the crap out of it and find a way to dry it out, careful with a hairdryer ... no flames OK. Also, you may not have gotten directly into the wet, but moisture builds up and cold causes condensation ... IF you find water, once you're sure it's dried out, start asking questions about re-sealing whatever it is so you don't have to go through this again.
OH, yeah, dry isn't going to start the bike, still need a good batery for that.

I'm going to hate having to scrap the PCV....i've loved how the bikes run with it versus stock.
It's possible that a sudden opening in exhaust would change (lean out) the AFR composition possibly leading to stalling, but that doesn't explain the screeching that you heard when stopping, hmm ... scratching the ole noggin.

Sorry, dont know how to make the link. So anyway, I figure what the heck and pull of the air cleaner and spray throttle body with throttle body cleaner. Start the bike up and the bike sounds normal. Take her for a lil ride. For the first few miles all seemed well, but the longer I rode....started popping on decel again and not idling properly even stalling at one stop sign. Get back home and think maybe it needs another spray with throttle body cleaner. So I remove air filter and repeat process. Take her for a spin and same scenario.....ok for first few miles and then the popping and the rough idle return. This time I even hear the screeching noise that started my dilema but I cant identify where its coming from.
So now I'm scratching my head. It could be a bad IAC....but i'm not sure if that would have caused the battery dying. Which leads me to believe the PCV might be the culprit. Guess the next test will be to remove PCV to see how it runs stock. I asked yesterday but i'll ask again....will I just need to unplug the PCV and plug the stock connector back in to the ECM AND disconnect the O2 sensor eliminator and plug back in to the stock harness to test this theory?
Last thoughts from me ... before pulling the PCV, try using the little red tube that comes with the carb cleaner and spray directly into the IAC port if you haven't done that already and make sure your air cleaner is actually clean. If the air cleaner is dirty could cause really mess with your AFR.
Loud pipes and screeching, the only solution for that is divorce... lol, just messin wit ya. GOOD LUCK.

To test your theory, however, you should be correct about just unplugging from the injectors and O2 sensors and plugging the OEM cables back in ....
May or may not be water in your electrical system ... I guess you would know whether that is plausible ...
If it is electrical/electronic, it seems to me it is as likely as not your ECM ... got a gremlin in it ... I suppose its possible ....
Popping on decel is a typical lean indicator, but there could be other causes ... and, with the screeching, it may be coincidental ....
Be sure to post what you discover ... would be interested in hearing what caused your problem ....
