Failure to Idle after Jumpstart

Battery was dead from leaving my lights on (duh on my part).
Bike was running just fine prior. Well anyways I had to get a jump, Just took 30 seconds and fired right up but wouldn't idle, it would start right up no prob but if i took my hand off the throttle it would die. smelled like it was running rich. I took the bike around the block to help charge the battery a little and see if the idle problem was just from flooding it? it kept wanting to die on me when I would come to a stop, had to keep the rpms up a little when i stopped. when driving she seemed to run normal. when I got home and stopped in the drive, I let off the thottle and it died.
I have a 02 EGC with a stage 1 and PC-V. I diconnected the battery to charge it and hoping the puter just needs to reset, had to go to work so I haven't been able to hook the battery back up to see if that cured it. Is there anything else I need to look for? or should disconnecting the battery do the trick? thanks!!

Just a guess on my behalf. It would seem like all vehicles that have a computer when the power is lost for an extended period of time it has to relearn what was lost. Did that make sense? I don't think just riding around the block would do it. Probably need "x" amount of time with normal driving to re-establish itself. Sorry I couldn't be more helpful.
 
Friend of mine has the same issue after a relay corroded and the fuel pump came on and drained the batter totally dead. Bike woud start and run fine until you took the jumper cables off. The battery was so far gone that it wouldn't take a charge and the charging system couldn't keep the bike running. New battery fixed it right up.
 
Is that the original battery?

It doesn't sound like it has enough power at low rpm.

You might need a new battery even though it is starting the bike at low rpm it may not have enough energy density left (charge) to keep it running properly.
 
My guess is the battery is not supplying enough voltage/amps to the system that needs a fully charged battery to keep itself happy. When you rev the motor, the stator is supplying enough juice to keep it running, and when you let it idle, it dies because voltage drops off. The battery needs a load test to see if if it will take and hold a charge, then go from there.
 
I had a similar problem on my previous bike, had the battery tested and it was bad, got a new battery and jumped right into a road trip without any problems.
