Wish there was a shield maker here in CA, so I could ride there and try out some different shields. By the time I buy one and try it, if I do not like it, shipping to return starts to really add up. Went through that with LRS and still have a shield here I do not like.

I since ordered one and installed one off ebay. I do see a slight distortion in one edge, but for $35 I will live with it. I do not get buffeting from it, but it is a little high. I wear a FF modular, and the only buffeting I get is if I ride with the face shield up, but chin guard down. The face shield apparently disrupts the airflow enough to buffet. I wear the face shield up, most of the time. If I wore my 3/4 I doubt I would get any at all.

 

I'm about same the same size as you. I have the 8 freedon shield in a light tint and it's the perfect height. Debating ordering a second one in a darker tint.

 

Make sure you’re happy with your seat first.

I got windshield set right, then changed to more comfortable seat (making wife happy). Then had to get a different windshield due to different seat height.

 

Lol yea I cut down my original, from a 10" to eventually an 8" then added DK lowering blocks on the rear. Duh, so now its really tricky for me to setup.

 

I park my bike in my garage, in the wheel chock that keeps it upright so makes it easy to swap shields, but the wheel chock lifts the front end and inch or so, making it real hard to know if I am on level with it.

I also noticed, when I tested my ebay shield, before removing the opaque cover, I couldn't see the chock at all. Was really kind of nerve racking on the road test. I have no idea how guys ride with dark shields. I know you look over, but when you are moving in close quarters, its a bit weird not seeing whats in front of me.

 

5'10 with a 32 inseam here. Have a Klockwerks 9.5" spoiler type windshield on my Electra Glide. Can easily see over it with no prob. Some wind, but no "buffeting".

 

When wind passes over the edge of a non-aerodynamic surface it causes a little whilrpool, or vortex to form. As you speed up, those vortices tear off and start whacking you in the head. Looks more or less like this. Note how they get bigger, the farther from the edge.




They can come from the top, the bottom, or the sides. You can do that trick where you place your arm across the chest to see if it's coming from below. However, based on what you describe, they are probably coming off the top. If you are lower, or closer to the screen, the vortex trains coming off the top of the screen are less likely to hit you.

Options:
1. Taller windscreen.
2. Windscreen with a lip, to make it seem taller. Note, the lip is very un-aerodynamic and will tend to spin off vortices like crazy so there's no guarantee it will work. Note, if you have the height set at upper lip level, you have to kick the wind up 4.5 inches to get over your head, more like six inches to get over your helmet. Tall order unless you're sitting pretty close to the windscreen.
3. You may be able to do something with the vent, if you can direct wind up the inside of the windscreen, and it sticks
4. Get a windscreen that's aerodynamic, and less likely to shed vortices

The latter does not kick the wind up and over, so it works best with a full face helmet, unless you don't mind looking through the windscreen. Or you can go shorter, if you don't mind having the wind break at about neck level. Sounds weird but that's basically what people are doing with bullet fairings, they are just trying to keep the wind off the chest, they let the head be in clean air, as if riding without a windscreen

Near as I can tell, California Scientific is the only vendor making an aerodynamic windscreen specifically designed not to shed vortices.

ETA
It depends on what you're up to
-- No helmet? We probably wouldn't be having this discussion... people who choose not to helmet don't seem to get buffeting very often, if at all
-- Full face helmet? CalSci is the obvious choice
-- Open face helmet? You got your work cut out for you, I think maybe the key is to have a LOW PROFILE helmet, otherwise you may be asking the impossible. IE to protect the face and eyes, AND be able to look over the windscreen, AND also kick the wind up over your mushroom-like noggin configuration

 

Depends what you ride. CalSci does not list the ultra classic or ultra limited in their line. Nor do they list the SG like the OP has. They list the RG, though, and tri glide.

 

I have a LRS 8" as well as a FS 8". Bith work really well but prefer the FS. The 8" seems to be a perfect height. Tried a KW but had too much distortion for me. I am 5'9".

 

Oops, 8.5” Not 9.5”
