Remove it & forget it...it's of no use and no bugger will want it either 



It seem disconnected from certain viewpoints.Its a piece if plastic crap that serves no obvious purpose.
99% of other motorcycles happily operate without it. What makes it "magic"?
Yeh.. that"ll be £199.00. Please. Merry xmas.there is an alu blanking plate you can get - possibly TouraTech

There is no need to fill the holes.
I am in Germany and so I get no choice: if they spotted that at the TüV inspection it would be a fail. So it stays.
I have added the "infill panels" and have the Cymarc 'spoiler' (lip immediately below the number plate). Not sure if the latter improves things, but I am not intending to experiment, having bought the thing
My Triumph Explorer didn't have one and kept me and its panniers clean in the wet. My GS1200LC covered me and its panniers in muck until I fitted a Mudsling and removed the rear fendner. Mine's staying off until I sell the bike.
Maybe not for you, but for those that do - it keeps the crap out of threads

If you remove it, there are 3 screw holes exposed to the elements (one looks like it would just leave a hole the prop shaft hub and let dirt and water in). Can the screws screw in all the way as they are really long?
Well, I decided to buy a small tube of black silicon sealant. I removed the 3 screws and just put a small plug of the sealant in the holes and covered the surface around the thread holes with a thin layer of the sealant. Works a treat.
