Hey Arther (well it's easier to spell anyway) I don't know if you're going to look on this as help or not, but here's my $0.03 worth on plexiglass. I've been riding behind a window for a long time now and my take on it is if you were to find the magic sweet spot one day, it wouldn't be the same the next. I find that wind direction and temperature make huge differences in the way windscreens block you. The smaller the windsheild the more they change. I've got the Yamaha Boulevard on mine and I find from day to day it can go from being worse than nothing at all to doing a great job even at high speeds. My take on it would be, if it's easy to adjust carry the proper tools with you and keep moving it around. You might find after a while you get pretty good and judging the best settings. Either that or it will be for sale on the forum in a couple of months. I hope this is seen as helping rather than hindering.

 

After much trial and error, I found it easier to leave the allens loose enough where I could move the shield as I was riding to find the "sweet spot". Well, it never happened..... So, since I like the feel of the wind on my face, I drilled 3 more holes above the existing ones and ended up lowering the 16" shield until the bottom almost touched the tach housing and went for an angle that was esthetically pleasing to the eye. What I ended up with is a shield that keeps the bulk of the wind off of my chest and thats enough for me.

I thought about lowering it to. I'll have to try it.

 

Placement of shield is critical to reduce wind blast directly to the face. I use the bridge of my nose as a guide to proper screen placement. Place windshield right below eye level and it usally will keep the blast off the face. The problem with the WindVest, you are giving up a little/lot of function for style. The windvest maintains that custom look. You want practical, get a Memphis Slim or even better a Memphis Fats.

 

I have found that typically, the slower you ride the more straight up it needs to be and likewise, the the faster you go the more angled back it needs to be to reduce turbulance. Maybe this is something to work with. I know this is not relative, but I have the big shot and for 70-75 mph parallel with the forks works pretty good.

 

After looking at your picture I noticed it has a "spoiler" lip at the top. This can be causing most of the problem. You may need to lay it back much further than with a straight-cut shield to smooth out the airflow. Think of it this way, if you were jumping ramps on a bike or something and you jump off a straight ramp, you would fly relatively straight, and if your ramp had a lip on the top it would tend to send you into a backflip. Air does the same thing. The backflipping air is colliding with the smooth air comming straight at the screen at that level, essentially pushing the flipping air back in your face. You have to reduce the lip angle to reduce the turbulance. Not trying to preach or anything, just some aerodymics backflashes from college. Just something to think about.

 

i ended up takeing mine off forever. youre sitting so far away from the windshield that it is less effective than if you didnt have one at all. i tried the spoiler around the lip trick, i even drilled holes to let some of the air pass through & that flopped too. the only thing that worked good was my back rest & cruise control. good luck

 

When I searched this forum 6 months ago seemed like the windvest got the best reviews. Oh well.

 

I still love my WindVest. It does work, but will never give you the full coverage that you seem to be looking for. The WindVest will always cup your ears, it is just not wide enough to be very practical. It does serve up some protection, but it's main function is style with very little practical application. It works for me.

 

I also have the WindVest and love it. As others have said, it will not take the place of a large shield but I find the upper lip directs the majority of the air up and over my head. You will definitely feel a little turbulence and I have never been able to keep a hat of any kind on, but I love the look and I am very comfortable regardless of what speed I'm riding. It will need to be adjusted differently for people of different heights. For instance, when my wife who is about 4-5 inches shorter than me rides my Warrior, it looks like a comedy act. Her shades get blown sideways, her face looks like it's in a wind tunnel, etc. Took her about one mile before she pulled over and said you can have this +$#&*!$# motorcycle. I didn't tell her it was the adjustment of the shield cause now I don't have to worry about her wanting to ride the beast (the Warrior I mean!!)

 

Well I guess I'll keep messing with it. I have a 600 mile ride this weekend and I can't be holding on to my visor everytime I hit 80. Thanks guys.

 

It has been said on this forum many times before: if you are after a nice big quiet zone of comfy dead air behind a shield, stop kidding yourself and get the Memphis Fats.

It's not the most stylish (IMO of course) but indeed it does the job well. I have the BigShot, 20" high above the headlamp, excellent compromise between style and function, but at my height of 6'1" it keeps the windblast off the chest and that's about all I can expect of it.

 

Have the 16", 5'8" Chest is fine, bugs smacking me in the forhead keep me awake and alert, Junebugs are another story.
