Or the bottom.
I had the exact same problem with the screen on my F800ST. Bad helmet buffeting and incredible windnoise. But instead of spending way more $$$ than I wanted, for a spoiler that may even make things worse for all I knew, I just made a "base" plate, attached it to the bike's stock windscreen mounts, and then bolted the shield to the new base plate, but now it was positioned a few inches higher up.
I fluked out I guess, but it worked perfectly first experimental try.
It cost me $3.00 (a scrap piece of hardboard panel from Home Depot), and about maybe an hour's total labour effort. (a pencil, hacksaw and a kettle of boiling water to help steam the wood to form an arc matching the OEM screen)
Totally removable, and it left no trace once I took it off. Three torx screw and 20 seconds, to put it on or off.
I'm sure a very similar thing could be made for the NCX. Note, this was simply an first trial run experiment, that I was going to replicate using better materials, like Lexan, or thin aluminum, or even fibreglass or carbon fibre, if it worked.
After painting the hardboard to make it waterproof for my shakedown test trip (a little over 3,000 km's) though, I just ended up leaving it as it was, and putting it on or off as I wanted, for city non-use or highway trips of any lengthier distance.
Now trust me, I know. I'm not saying this is the be all-end all, or everyone's cup of tea, but at least it's a cheap 'n easy way to see if varying heights of windscreens can help or hinder, without having to pay for an expensive windscreen not knowing the outcome first.
I was also undecided if I wanted to space the windshield out from the base plate with thicker rubber washers, to allow an air gap for laminar flow up the backside of the screen, or to add the same thickness of material to the outside of the base plate, to bring the level flush with the outside of the screen, for smoother flow on the front. I ended up trading in my F800 for the NCX before I was able to continue my experiments though.
Thanks for the idea...adding from the bottom...this way i can make use of the existing hole without drilling any...great idea!!
