These instructions are for the F4+4 which does not move. Modify to your installation according to your situation.
The OEM shield has ridges on either side for strength (I assume). These edges are about two inches across and raised 1/8" above the rest of the shield making a "recess" on the opposite face that contacts the visor. The visor is raised about 1/8" there to accommodate hence has a recess along the center. When one attaches a shield that does not have these ridges, one is left with a space in between nearly running the length of the visor. This causes the after market shield to rattle over bumps at low speed and may cause the shield to "flutter" in the wind at high speeds.
was to remove the Teflon tape not only along the top of the visor, but
also the "slider" tape along the channels where the shield rides when
adjusted. In applying the industrial strength Velcro loop, I made the
edge smooth where the raised part of the visor is starting from left to
right. As I worked my way across keeping the upper edge flush to the top
of the visor I made a natural wrinkle (almost as a side effect) in the
Velcro along the recessed area. The wrinkle was 1" below the top of the
visor. When I reached the other side raised portion, I made sure there
was no wrinkle there.
On the "sliders" below, I covered those with strips of Velcro EXCEPT for
the "sliders" on the raised portion at the ends.
I made sure that the ratchet was down at the bottom so that it would
latch as it was pulled up. I installed the shield and pulled it up two
notches on the ratchet and buttoned down the holder plate and installed
SUCK BIG TIME. BIG TIME!
Though I've installed and removed and installed and removed the tunnel fillers trying to determine if they work, I could never actually tell adequately until this method dawned in my slow moving brain.
INSTALL ONE SIDE and GO FOR A RIDE! Determine for yourself if they improve the air flow enough for you to put up with the hamper to slow speed turning. I have determined that they do improve it enough - for me..
I have a problem with my FIFTH CRANIAL NERVE (no, not the one that helps you think, tho it may seem so at times). This is the nerve that supplies sensation from the side of your face to your brain (see pic). I have numbness on the entire right side of my face which I guess is from riding 700,000 miles with little or no windshield over the years. When it is worst, you could clamp a vice grip on my ear lobe and I would not know it. At times I also suffer from minor Bell's Palsy (different nerve) which causes just my right eye to droop a tiny bit enough that I get "dry eye."
Cliff "chalayko", a member of the GL1800 Riders recommended I try my Tunnel Fillers again. I went through the process stated above about four times. Today, it came to me to try ONE SIDE ONLY. There is a difference though not one that I would call significant. However, the improvement in reduced air flow is precisely on my cheeks and ears EXACTLY where those troublesome nerves originate. So I'm keeping them in.
Pics are a
little hard to get because of where they are. The fat part goes in the
back and the thin part in the front. They install just below the upper
fork clamp of the top bridge and you want to get the front part as high
as possible. A patch of sticky back Velcro attached to the tunnel so the
filler can grab it helps.
Below are the pics and the form. One might think that these things are not very sturdy, but I've had them to 100mph among 18 wheeler traffic with my qwik release in place with no problems. These may be a little wide for your tastes, but they keep the wind off my hip joints and I can use the highway pegs and not get heat from the radiators on my legs. You can surely make them slimmer by preserving the intricate curves and cutting the long straight edge more narrow.
NOTE: I have made my own version of the BBP lowers made of stiff vinyl so they don't break with a sharp turn or a tip over. I attach them to the crash bars with nothing more than a pair of zip ties and keep spare ties in my bags to replace Justin Case one breaks. The ties break, preserving the deflectors.
The mirror hand wings are a must install on every GL1800. Reduces buffeting for
the passenger and keeps your hands warm and dry during those moments when it's
needed. The Hand Wings are something that I cannot do without. Heated
grips and lighter gloves negating the need for Bulky Heated golves make them
indispensible. In the summer, open them HALFWAY so they are parallel with the bike and you will get
all the air you need inside the envelope to keep you cool when necessary.
Just half way, no more because you won't get anymore air anyway and if you do
they likely will not hold position.

One can make an appliance to protect oneself with a simple helmet visor and some velcro. This works very well in battling the malady of the Gold Wing backdraft.
