It's really not that hard to do.
HERE is a link to my photo album where I have a few photos of it. Be sure to read the captions
You do not need to remove ALL the panels you might think the service manual implies need to be removed. Careful reading of the specific sections starting with the Windshield removal and working back reveals far less of a job.
Before you start you will want to get a strip of 3M Dual-Lock material. This is not Velcro since but is the tiny plastic stubs on both sides that interlock, and is stronger than Velcro. I got mine at Radio Shack and they call it Super Lock strips, but on the peel off backing it still says 3M Dual-Lock
. You only need 2 strips about 1-1/2 to 2 inches to go on the new shield in the same location as they are on the shorty.
1- pop off the front mirror covers. They unsnap from the bike and are also held loosely by a strap so they don't get lost if they are knocked off on the road. There is one tab between the front cover and the little back cover (just inside the mirror glass) that you need to take care with but nothing major. Just let the covers hang there by the strap.
2- remove the 2 top mirror cover clips on each side. Careful here since there are some very small insert/washers between the clips and the hole where they go so keep an eye out for those. Some of us have found one of the metal tabs inside one of those clips bent in. Now is a good time to simply use your screw driver to bend it back like the other metal tabs, but not too far since you do want it to hold the mirror cover. Again, nothing major but something to check.
3- While lifting the top center of the front garnish pull it forward and up/out from the bike. There are a few clips on the lower front of the garnish that latch into tabs on the center of the headlight assembly. The garnish will come off with some playing with it.
4- There are 4 screws with vinyl and rubber washers that go into expansion nuts to hold the shield on. One on each end and 2 in the middle. Remove those being careful to save those washers and paying attention to what order they are on the screw. The shorty shield will now come off.
5- Move the 2 center expansion nuts to the lower holes in the center bracket. Should be easy to see where that is. My tall shield came with 4 expansion nuts that were not "conditioned" and I considered using those, but decided it was best to simply save those for extras. Use the original nuts as long as they are workable. They should slide right out of the upper holes and slip right into the lower holes. The tall shield is a little longer below as well as above. This is to compensate for the extra loads of the taller shield caused by wind force.
6- Note carefully where the Dual-Lock strips are on the shorty shield and apply new strips to the tall shield in the same location. I carefully layed the shorty over my tall shield to verify where they should go. IMPORTANT: Clean the plastic where you will stick on the strips with rubbing alcohol and let dry before sticking them on. They will stay better that way.
7- Mount the tall shield using the screws removed before. Don't over tighten these screws, very snug is good enough since the nuts are in rubber.
8- Re-install the front garnish, clipping it over the tabs at the headlight first and then laying it down on the shield and lining up with the mounting holes on the sides. Press down, not too hard, on the top center of the garnish where the Dual-Lock strips are to latch onto the shield.
9- Reattach the mirror clips.
10- Snap on the front mirror covers.
Done.
Almost takes longer to read this than to do it!
Go riding and enjoy the calm comfort that results from increased wind protection and still smooth air over the top.
PS- I think I remembered everything. I am writing this from memory
