pretty easy, 4 screws hold the outer shell to the inner. Once those are out, the inner is held onto the bars with clamps.
The clutch side has the connector for the ipod and the 12V connector to disconnect. You may want to just "tie up" the ipod connector, its connected inside the fairing.
I take the deflectors out of mine for summer but leave the rest of the lower in place because I like the storage. Still warm, but better. There's an "E" clip on the bottom of the deflector, then pull the pin, you have to gently lift deflector to get it over the pivot point, but that's not too difficult, then the whole piece pulls down out of the friction hinge.
There are multiple threads about heat on the XCT. Some say have the deflectors open an inch, some say 2 inches, some say open all the way then close an inch... Just about as many opinions as bikes.
Good luck, let us know your results.
