MadStad RoboKnob brackets are designed to bolt to a curved surface like the
black adapter plate included in this kit. The new windshield attaches to the top
(front) of the brackets with Phillips screws. Loosening the two adjustment
knobs allow you to change the windshield height and tilt without getting off of
the bike, and without any tools.
You will need to remove your factory windshield; it is not adaptable for use
with these brackets. However you will be using the factory windshield screws
to bolt on our black adapter plate.
STEP 1: Bracket Installation
Your Robo Knob brackets attach to the black acrylic adapter plate, and you will
need to bolt them on before installing the plate to the bike. Use the four M6 x 16
screws with flat washers and lock nuts as shown in the diagram below. DO NOT
OVERTIGHTEN!
Go to Page 3 to see what the brackets should look like once attached to the
adapter plate.

The knobs on the brackets go to the insides (facing each other) with the knob
sides up. When both brackets are installed it should look like the diagram below:
STEP 2: Install the Adapter Plate
The adapter plate attaches to the fairing in place of the stock shield using the
original factory windshield screws and washers. It’s basically a shorty shield,
only with our brackets attached.
NOTE: Be careful not to push too hard on the windshield screws or you will
lose your factory rubber well nuts down inside the fairing! You may want to
pull all of the well nuts out of the fairing and get them started on the screws
(hanging through the back of the plate). That way you know they have started to
thread and won’t accidentally fall in. Then insert the whole thing into the fairing
and go around and tighten up all five screws.
You can also order replacement oversized rubber well nuts from MadStad
Engineering. These are not included in this kit but if you want nuts guaranteed
not to fall into your fairing, then we have these available.

Windshield Installation
Once the adapter plate is installed, the windshield attaches to the front of the
brackets with Phillips screws and washers as shown below. Insert all four screws
and washers into the four windshield holes as shown before attempting to attach
the windshield onto the RoboBrackets. The rubber washers on the bottom will
hold the screws in place.
When attaching the shield to the brackets, we recommend that you first install
the upper and lower screws on one side, then install the upper and lower screws
on the other side. The rubber well nuts are flexible and shield holes are oversized
so you can nudge the shield around to align the T-screws with the holes properly.
Tighten the screws with a screwdriver until the tips of the screws come out of the
bottom of the well nuts, and the well nuts begin to swell up (bulge) behind the
brackets.
DO NOT OVERTIGHTEN THE T-SCREWS! The rubber well nuts cannot be
pulled up out of the brackets, even if they are not tight, so tighten only until the
well nuts begin to swell up and the shield is snug against the brackets. Over
tightening is unnecessary and can damage the rubber well nuts.

Adjusting the RoboKnob Brackets
The knob screws release the brackets allowing the windshield to slide and tilt.
These knob screws must always be tightened securely before riding. DO NOT
attempt to adjust the brackets while riding! You must come to a complete stop
before making adjustments. Also make sure that you do not set the windshield
in such a way that causes your handlebars or hand guards (if installed) to hit the
windshield when turning, or before reaching full lock.
To make adjustments, loosen the knobs 1-2 turns and set the windshield so the
top edge is at about your chin level as you look straight ahead while seated on
the bike. Set the angle at approximately 60 degrees. (Use the angle guide on the
back page of this manual as a guide.) Tighten the knobs and go for a ride to see
if you now have smooth airflow over and around your helmet. Do this on a
calm day if at all possible; windy days make it hard to judge the airflow. Don’t
ever try to adjust the mount while in motion!
WARNING: If you tilt the shield fully backward, it may make contact with the
top edge of the brackets. This could scratch the back of your shield, so please
check to make sure there is no contact.
To try a different windshield position, bring the motorcycle to a complete stop
and out of traffic. Loosen the two knob screws and tilt the windshield forward
or back 2-3 degrees or so, and/or adjust it up or down if necessary. Re-tighten
the knobs and go for another ride.
Continue experimenting with different positions at different speeds until you
find a combination of height and rake angle that eliminates buffeting and gives
a smoother ride. You may have more than one favorite position, for example
shield tilted forward on cooler days, and shield tilted back for hot days to let
more air to your body. Or, if you normally ride with a low-slung solo seat but
switch to a taller 2-up saddle with a passenger, you can simply raise the shield
an inch or two without changing the angle.

PIVOT SCREWS
The MadStad mount has a pivot screw on each set of brackets, located near
the center of the bottom bracket. A nylon lock nut keeps the screw snugly in
place, yet allows the brackets to slide back and forth. It is adjusted at the
factory to have a minimum of play yet still allow the brackets to move. Over
time it may loosen up a bit so to adjust the tightness of this pivot screw, use
the 4mm Allen wrench provided along with a 10mm socket or crescent
wrench to make the adjustment. If you tighten the lock nut completely you
will not be able to slide the brackets up and down.
Notes on Windshield Angle
Most windshields work best when set at a 55-60 degree angle. We have
provided an angle guide on the back page of this manual so that you can
check and see if your shield is set somewhere in this range.
To check your shield angle, your bike should be in an upright position either
on a center stand or held up by a helper. Set the spine (folded edge) of the
manual against the front of the shield. If the large arrow marked 60° is
pointing straight up, then your shield is at a 60 degree angle. (See diagram on
Page 5.) A little farther back and your angle would somewhere between 55
and 60 degrees. Anywhere in this range is fine for your initial test ride. You
may want the shield at 57-59 degrees when riding solo, but push it to a more
vertical angle with a passenger. (A 63-64 degree angle can bump the air up a
little higher to clear your passenger’s head.)
There are free smartphone apps that turn your phone into an angle finder
(inclinometer) so you can see exactly where you’re at. You can also purchase
mechanical dial angle finders at your local hardware store, but these things are
not a requirement. Most riders can find their sweet spot through simple trial
and error.
