My '07 was about halfway through the fairing at 27k miles. Dealer replaced the stereo two months earlier - didn't say a word....
Here's the steps:
1) Go to the local Autozone and buy a package of door edge moulding (25" or longer, 24 is too short), a package of small zip-ties, and a Plastic Bumper Repair Kit (double-syringe epoxy coumpound). Total cost ~$12.
2) Tools needed: T-25 Torx driver, 1/2" wrench, diagonal cutters or fingernail clippers, Allen wrenches, hand-held grinder (I used a 4.5" with a flap disk, some have used a Dremel tool), a thick towel/blanket for covering the front fender, and something to set the fairing on (towel/blanket/carpet/lawn). COVER THE FRONT FENDER BEFORE YOU START!!!!
3) Remove the six Torx screws from the inside edge of the fairing (don't worry - it won't fall off!)
4) Remove the 4 1/2" chrome acorn nuts and washers from the brackets above the engine guard (behind the turn signals). Two of these usually bring the studs with them - that's OK. Pull the turn signals out and move the wiring to the exposed slots.
5) The outer fairing is now being held in place by two hooks behind the headlights, several fingers that interlock with the inner fairing, and whatever of that crappy glue the MoCo uses that has seeped into the joint. USING NO TOOLS, separate the outer fairing from the inner - start at the bottom and lift up and forward. As it separates, it will have to be lifter off the hooks behind the headlights (1/2" or so). As it comes free, it's really NOT - you or your helper must reach in and unplug the headlight wiring harness. Then you can set the outer fairing down and examine the two grooves worn in it.
6) Wipe the grooves clean, mix some bumper repair, and apply it to fill the grooves. Use the tool supplied to smooth the surface. Set aside to dry.
7) Remove the radio by cutting the zip-ties as needed, unplug the antenna and connectot from the back of the radio, and remove the four Allen bolts that hold it in place. The service manual says to take it out through the inner fairing, but my radio has a L-shaped bracket on top that required removing to through the front. Set radio aside.
8) Scribe or mark a line 1/4" down from the top of the radio brackets - see pics in thread http://www.hdforums.com/forum/touring-models/445057-tips-and-tricks-road-glide-fairing-pictures.html. Gride to the mark (NOT REAL CRITICAL).
9) Observe the placement of the crappy seal the Moco uses between the outer and inner fairings from the edge of the windshield down the sides to near the forks. Remove it and as much of the glue as you can without scratching the plastic - I used my thumbnail. Replace with the auto door moulding. You will cut off a small piece on each side - save these scraps.
10) I sprayed some black emanel on a Q-tip and used it to paint the raw edges of the radio bracket, then used the scraps of door trim to pad the edge.
11) Replace the radio and zip-ties. Don't forget the antenna (don't ask!)
12) Remove the headlight cover/bezel. The headlights are mounted to a bracket that is then held to the outer fairing by three adjusters. If you pinch the edges of the plastic "nuts" on the adjusters, you can pop the whole assembly out after you unplug one headlight. Doing so gives you a much better way to reinstall the outer fairing, as you can now look through the front to align the hooks.
13) Rehang the outer fairing on the hooks. After it's on the hooks, you can align all the "fingers" between the outer/inner fairings and get the turn signal wiring aligned. When you get it all lined up, replace the Torx screws but do not tighten them until last. Remount the turn signals. When satisfied with fit, tighten them all - don't overtighten the Torx screws, as you will strip the plastic.
14) Plug the headlights back in and "pop" them in place. Replace the cover/bezel.
15) Wipe it down, pop a cold one, admire your work.
