Problems With Madstad Mount

Replaced the standard Zuk shield with a Givi last week. Wow what a wonderful windshield and only $101 at RLmotorcycles. The calm air, the no buffeting, it was like smooth air heaven. But this was short-lived as soon my Madstad mount allowed the windshield to tilt back once I reached speeds above 70mph. Stopped, retightened the wingnuts, back on the road and wham the shield rotates back again. Stopped, took the wingnuts apart, cleaned the washers and lock washers, retightened the wing nuts, and back on the road. This held for about 5 miles then again the shield rotated back again. I realize that the larger surface area of the Givi puts more strain on the Madstad bracket but I was under the impression that the madstad was up to the task. Has anyone else experienced this problem and how did you solve it? My system has the twin wingnut configuration and I have really cranked it as tight as possible.

When you say wingnut, are these round knobs? I have just installed the Madstad on my new Wee with the Givi shield and have had no problems even in high winds and 90+ mph. Someone else reported the same problem a few months ago though. I have heard of no others with the problem on the new bracket design.

My Madstad does not have any knobs. It has the twin wingnut with lock washer fasteners.

I have just bought a brand spanking new MadStad and it comes with the round tightening knobs. I have tried the MRA but still buffet and so will be trying the GIVI next.

One of my knobs came loose due to the vibrations from the engine. A fix would be to mark where the fitting works best and then replace the knobs (or wingnuts) with two lock nuts. Should never move again!

Are the nuts loosening up? If so have you thought of putting some loctite on the threads? Another thing that may help is a thin rubber washer to put between the bracket and the bolt or nut. If it is staying tight an just slipping where it is metal on metal the rubber washer should help give it more grip.

For $6, you can upgrade to the newer adjustment knobs:

Replacement Adjustment Knobs for MadStad AWM
SKU: AWM-AK
This is a set of round plastic adjustment knobs with stainless steel screw inserts. They replace the wing screw adjusters that were included with earlier series MadStad adjustable windshield mounts.
THESE KNOBS ARE STANDARD EQUIPMENT ON ALL NEW MADSTAD MOUNTS. They improve the look and are easier to grip than the previous wing screws.
Simple drop-in replacement, they also come with rubberized sealing washers for a strong hold, and stainless track nuts that allow one-handed adjustment.

I have the wing nuts on mine, but I tightened the bottom lock nut that just slides up and down. (just a little) I get less vibration and it stays locked up now.

I have the Madstad with a Givi screen and have had the same problem with the shield angling all the way back under high speeds. I have the newer design with the plastic adjustment knobs and not the wing nuts. The adjustment knobs are still very tight but the screen is tilted back. I have not contacted Mark about the issue yet. The proposed solutions that people have listed here, loctite, nylocks may work but also ruin the entire concept of an adjustable windshield mount.

I did indeed contact the good folks at Madstad and Mark has emailed back to say that he is sending me some new fasteners that should solve the problem. In the interim, I have replaced the small washers andlock nuts with larger items and added soft rubber washers on the inside and outside of each bracket. Lastly I cranked on each set of wingnuts to the point of brain hemorrhage then marked the position with whiteout. Can you believe it. They still move at speeds above 70mph. Not nearly as much as before but the mounts still can't hold the load of the larger Givi shield. But on the bright side when the shield is in place it does a fabulous job of cleaning up the air around the face. I can actually hear that the motor sounds like the car on the old Jetson's cartoon.
