Bike wont start after changing the Generator cover..

[louisianagz]

I have a 2009 gz that has been sitting for about three weeks waiting for me to replace the generator cover. Finally got it (along with the stator) replaced yesterday. Gave the gasket goo overnight to set and tried to crank her this morning, nothing. Starter just clicks. Hook it up to a car to jump it off and it starts to turn over very slowly. A few minutes later it just clicks again. Just one single click. Doesn't seem like jumping it off is helping. I did move one gear inside the motor that slid loosely in and out to remove some debris from behind it, but pushed it back into its original position before replacing the cover. Is it normal for the battery to be completely dead after just 3 weeks?
