It's not TOO difficult. But you'll be fumbling and cursing while trying to hold the front fairing in one arm while getting your other arm inside to disconnect the headlight connector and pop out the turn signals. You can let the fairing rest on the front fender and try to stabilize it with your knees or something. The turn signal bulbs come loose by turning counter-clockwise a half turn or so. They have rubber O-rings which might fall off so watch for them. Their wiring is loosely in little hooks from which it will come right out. No need to unplug their connectors.
I lay a towel over the front fender to keep from scratching it -- push it through the front forks to make sure it stays in place.
Fairing comes loose by screws starting up near the instruments on each side and there's 3 or 4 more going down the edge of the black plastic till you get to the place where it meets the side skirts. There's one screw front middle right above the horn opening. Once they're all out it might start to drop or you might have to jiggle and tug.
Headlight bulb has a retainer which is held by a screw or two.
Edit: Disregard all of this! See below!
Going back on with the fairing, you have to get all the little alignment tabs lined up and going in properly. usually takes me a lot of struggling but, again, not TOO bad. :-)
By the way, can you briefly tell me what a PIAA light is?
