I took mine out to put in a '13. Agree no need to take the shelter off. Just loosen and prop it up. If yours is like mine it will hang up around the ignition but I can't remember if there are screws or just a groumet there The filters for the fans will be easy to get to but they will only be needed when the fans are running which is when you are stopped in traffic. The one which is probably the most important is the one for the fuel filter under the seat.
A word of caution: THE BIG 15 PIN CONNECTOR AT THE RIGHT SIDE OF BIKE MIGHT BE A LITTLE HARD TO DISCONNECT. HAVE PATIENCE WITH IT OR YOU MIGHT DAMAGE SOME OF THE LITTLE WIRES. Don't ask me how I know.
