Battery keeps going dead
So I posted about a month ago how I went to start my bike and it turned over slowly and then reset the clock. So I thought it was just a dead battery, charged it and everything was fine. Two weeks later same thing. And now this morning, which is approximately another two weeks later same thing again.
Thankfully this morning it had enough juice to prime the EFI, so I could push start it but that was all the power it had.
I am sure the previous owner had this problem too because he told me he put a new battery in the bike just a couple weeks before I got the bike so I don't think it is a battery issue.
I am trying to figure what is happening. I know it has enough juice from the stator to power everything while the bike is running, I have no problems with dimming lights or slow signals. But not enough to charge the battery?
Help.

Check your battery voltage when the bike is off, then with the bike running. I forget the exact numbers but if is lower than 14v @ 4-5k rpm either the stator or regulator/rectifier is bad.
If that checks out, you could have something drawing power from the battery when the bike is off.
