Windshield mod, need help

It is my plan to combine what I consider the 2 best windshields into 1. The MRA Vario and the Givi. I intend to install the adjustable lip fron the rather narrow MRA Vario on the much wider Givi, creating the ultimate windshield. I have both, and believe combined are the ultimate answer to wind/buffeting protection, along with my Madstat, of course. My Question...How do I drill holes in the Givi without destroying it? Has anyone done this. Or what kind of shop could do it for me? I will post pics of the finished product and a ride report when it is all done.

I bought a used Givi to do the same thing, but I haven't decided which spoiler to buy yet. Not sure what to tell you about drilling into the Givi, but if whatever you do works, let me know!

The windshield should be pretty easy to drill into. A drill bit with a centering tip can be had at any big box hardware store. That and a slow and steady start with a drill. Prop the shield with old towels or the like under it to keep it stable.
Good luck.

DO NOT DO THIS. If you use a standard bit, it will grab and crack the windshield.

Drill bits for plastics have a different included angle from the general purpose bits sold in most stores. If you are a very careful man, you can drill a tiny pilot hole and then drill it out in steps to the correct diameter.

Or you can buy the proper tool - plastic bits - at a plastics supply house. There are more around than you'd think.

Or grind the tip to the correct angle.




...Or buy a CalSci and be done with it.....

I solved my windshield proble

Its on a shelf in the garage

Helmet buffetting solved.


National something makes a windsheild that is suposedly better

It is formed and has cut outs that allegedly move the vortexs to the side.

+1 for what Garandman said. Use the right tool for the job. This job can be made easier (more likely to work) for noobs if the shield is held down to a drill press table. The drill press gives you more control over the bit, which will prevent it from trying to dig in too deep when cutting. Alcohol can be used as a lube, which will also stop the bit from grabbing. Spray it on or build a dam from putty around the hole and fill with alcohol. Cut slowly at slow speed.
Having said all that I think you should try the combination of the two out using industrial velcro before you actually drill that Givi. You are combining two separate airfoil systems, and although they are good alone, there is no guarantee they will be better when combined.

ADVENTURE, like beauty, is in the eye of the beholder.

How easily would a soldering iron push through the screen? Not sure if this would leave a clean hole or if residue from the iron would "messy" it up.

Any thoughts?

Try putting some masking tape over the area you want to drill, then use "very" light pressure on the drill bit so it doesnt grab, and shatter the screen.

I have already sat the spoiler from the MRA Vario on the Givi, the lay of the adjustible bracket sits perfectly on the Givi, as the curvature of the upper portion of the 2 windshields appear to be identical. Thank you for the suggestion on the plastic drill bits. I think I will inquire if a plastics supply house will actually agree to drill the holes for me. Confession time, the reason for my question,I have already destroyed a brand new Givi trying to drill the first hole, using a conventional wood bit. Figured it would be easy...the windshield cracked almost immediatly. Not one to give up on what I believe is a good idea, I am trying again
