Matt, I think there is a way to search for the culprit that is draining the battery.
Electrical guru's please correct me if I am wrong!!
"key off"
Remove the ground wire to the battery.
Place an inexpensive (harbor freight type) volt meter between the negative lead and the battery negative.
You should see 12 volts on the meter.
Disconnect the clock, (that will remove all power that is supposed to be on).
You should see 0 volts.
If you see volts,,,
start pulling fuses and unplugging wires. ("1" at a time)
Eventually you will see the voltage drop to 0.
When that happens, you will know approx. where the drain is located.
Keep troubleshooting from there and you should find the drain.
Ride safe, Ted
