Wind Buff with HD Windsplitter 19 inch for Fat Boy
Im 6.4 and ride a FLFB with a low riser - handlebar Setup and a Badlander seat (Tallboy Seat is next).
I have ordered a Windspiltter 19 Inch - what Ive got is massive wind buffering (?) on my Full Face helmet. Now its my plan to shorten the shield or to remove the curved end of the shield.
Any suggestions or complaints?
thanks.

I wouldn't cut it straight across. I don't know why, but there's a reason that all motorcycle windshields are curved. Youtube has a few videos on how to do it.
I said that I'd never put a windshield on my 18 Fatboy. But decided that I'll add one before my next 2000 mile trip, which I'm hoping will be later this summer. I bought a used 19" Memphis Shades for only $50.. Now I'm on the lookout for a set of used brackets at a good price.
I contacted Dremel and they recommended using EZ476 cutting wheel and the EZ402 lock mandrel.

The kickback will create a vent between the nacelle and the bottom of the windshield which allows air to flow through it and fill the negative space behind the windshield.
The air doesn't really come back at you from the vent so you wont have to deal with wind pressure, but you will have the cooling air so you dont get overeheated from a lack of airflow.
It's very cheap to build too.
It's made of(1 Side):
Perch Clamp bolts(Really any bolt that can be threaded through the rubber dowel)
3Inch Mending Plates(I got mine at Ace Hardware)
2 Washers(large surface area.
Lock Washer
Nut.
I assembled mine in this order
Bolt Head, Mending Plate, Washer, Dowel, Washer, Lock Washer, Nut.
I had to ever so slightly drill out each hole to get the perch clamp bolt to thread through easily.
Yes you need the Lock Washer, I didnt have lock washers on first, and one of them shook loose the nut, and the other was loose. Lock Washer is a must.
It's a bit of a process of getting the windshield on, because you have to loosen the nacelle bolt to be able to swing the dowels into the lower windshield mount slot.
But once it's in there and the nacelle bolt is tightened down completely, they stay put and it makes the windshield much better. For me anyways.
I have the 15inch HD Windsplitter, and I'm 5ft10inch.

I've had this same dilemma with the windshield on my Slim. I tried changing the angle of it as explained above. I didn't like the look of the mending plates so I found something nicer in black or chrome on Amazon. I tried them in both in I think 2" and 3" inches.. It helped but didn't eliminate the buffeting. I was going to try fangs on the forks, but being in So CA I was worried about the heat and cutting down the airflow to the engine and my legs. What seem to help the most was installing a pass-through air vent in the shield. There are a couple of DIY youtube videos on installing a Goldwing vent on Harley windshields. You can find the vents on Amazon and eBay for like $20 bucks.

There's a range of shield heights that will cause maximum head buffeting just below the correct height for looking over. It looks like @FranBunnyFFXII went lower, but she might be getting bug spatter on the helmet visor - depends where you live. We got a lot of bugs around here in the glaciated pothole region of the U.S., so I wanted the precision look-over shield. I can confirm bugs go sailing over my head now!
