Cut two panels of 1/8” plastic. Round
each corner to ¾” radius .
I am currently using panels 14”L.
X 5.5”W. You may want to use panels that are a few inches longer. Taller
riders need longer panels. My panels start about ½” above the tops
of my lowers.
Note: Square corners will cause vibration!
The uppers are on the “Inside” of the
shield, and overlap the shield by 1.5”. Two stainless bolts – 10X24 ¾”
and Acorn nuts fasten the uppers (along with cushioning washers) to
each side of the shield.
Drill two holes in the Panels 7” apart,
the first is approximately 3” down from the top of the panel. The holes
are located ¾” in from the edge of the panel. It’s best to cover the
area with masking tape before drilling as it helps to prevent chipping if
To help prevent cracking, use a larger
drill bit (by hand) and ream out both sides of each hole.
Now tape the drilled panels to the
inside of the windshield. The holes you drill in the shield should be ¾”
in from the edge of the shield. Align the panels so that you are sure they
are symmetrical. Sit on the bike and check alignment. The panels should project
beyond the edge of the shield by approximately 3”.
you drill the windshield holes, tape the uppers to the outside surface of
windshield in the final position. Take the bike out for a ride and determine
if the uppers are
doing their job.
Now mark the windshield and drill
the mounting holes.
Hardware: I use a “Special”
stainless washer I have made for my lowers, that has rubber bonded to one
side. You will have to locate a supply of Neoprene rubber washers – usually
at Home Depot Or Lowes.
From the front of the windshield here
is the hardware sequence:
10X24 X ¾” button head bolt
1/8” plastic panel
SS Acorn nut.
Now tighten hardware (remember that
Acrylic cracks easily), but not too tight.
You may find that the windshield curves
slightly from top to bottom, causing the top and bottom of the new panels
to contact your windshield. A very small bit of foam tape at each contact
point will solve that problem.
I like the looks of green plastic,
but I have also used red and clear. The green uppers in the picture are an
early, shorter version – 12” tall. They worked well also.
Now take the bike out for a ride.
At highway speed, move your hand outward from the bars. About 1” or 2” out
you will feel the extremely strong wind blast that is being deflected around
your handgrips. Life is good!!
In all of the miles I have used the
“Uppers” I have never seen any sign of vibration.
If you do not like the deflectors,
you can easily plug the holes with some chromed plastic mushroom caps , or
Have fun and ride safely my friends.
