Does anyone have an idea on what would cause a battery to drain after being charged a few hours earlier? The battery I have was purchased new a few months ago and I just started having issues with it. It will start my bike right after it's charged but not after I disconnect the charger and let it sit.
First thought was a bad battery (dead cell). That doesn't appear to be the issue.
When I shut down the Bike, I always check to make certain that the key is in the off position, not the position that keeps the parking lights on.
Any help would be appreciated, Thanks.

Also, the decomp controller may be bad.
Test the battery 1st.
next disconnect the decomp controller (black box over carb)
or connect an amp meter
