Windshield recurve

[Jaskin71]

Hello all, still fighting and fighting and fighting with the wind buffeting.

I'm thinking about to recurve the top on my standard IS windshield .

Anyone manged to do that? Any experience?

Thanks in advance for any suggestions.
Ride safe Jiri

   Maybe apples and oranges But I'm 6' 2" and I'm on a stock height I/S W/S. I have slight buffeting at about a buck twenty. Now should I raise up into the wind stream-YUP severe buffeting at that buck twenty. Far as doing the recurve-That IS uncharted waters fer this old guy! Is there an add on recurve SOMEWHERE fer sale? And query here-is your W/S stock height shorter taller narrower after market? This IS needed info fer a fix. RIDE SAFE.

The OEM shield for the standard already has a mild recurve. I have no significant buffeting. I’m only 5’8” so the stock height is a very tiny bit too tall. But not enough for me to do anything about. Maybe a slight adjustment in the angle of the shield can help

Clearview windshields have a larger amount of recurve, and can be ordered at different heights: https://www.clearviewshields.com/

I know they have them.
Im asking if someone did that him self. If there is any chance to heat up the shield and bend it.

Thanks

I got one of these from Wish for my Shadow Tourer, works great.  I get zero buffeting, except when the wind hits at just the right angle from the side or when around semi's.

I got the large size, attached it to the top of my standard size shield.  You can adjust the height and angle, or remove it when you're just going slow on backroads.

I added a bracket to the lower mount. It moves the bottom of the shield out which brings the top back. The increased rake eliminates buffeting. I’m 5’10” .

Wind deflectors mounted to your forks will solve your buffeting issue. Memphis Shades makes some that fit.

In my experience buffeting occurs for me when my eyes are ore than 2" above the top of the screen.  My Clearview screen is the largest one with the wider sides and no buffeting.  I'm 6'1" sitting on a Russell DayLong seat at about the original OEM height.   Hope that helps.

I wrote up changing the angle of your shield with an easy to implement and reversible mod over 20 years ago.  Lots of benefits including fixing buffeting.  I did it in this mod with a Rifle shield but it is the same for the Hondaline and presumably other shields as well.  Read about the benefits and the how-to here - http://horseapple.com/Valkyrie/Tech_Tips/Windshield_Tipping/windshield_tipping.html

More recently I modified my mounts on Jade more, changed the upper and lower brackets.  With this mod I can set the shield at multiple heights and angles easily.  ie., on the return ride from Taos Inzane, I wanted to change it so I did in a gas station in 10 minutes with 2 wrenches.  If you have access to metal working tools including welding this is a great mod on a Hondaline or Clearview shield (which uses the Honda brackets).  Likely others as well.  I am not offering this mod as a product for sale as it requires hands-on to the upper end of the expensive shield bracket as I implemented it - welded and polished SS.






I normally look over the shield 3-4 inches with no turbulence on my head.  BONUS the angled shield provides rain shelter for electronics in the cockpit - Escort radar, trailer brake control,  cell phone, 12v and USB Road Proof module, GPS (though Zumos are immersible), fuel panel switches.

so the answer is, u need a taller and possibly wider I/S windshield

Windshields with this design sometimes use the term "flip", "flare", "recurve", "wave", "contour" or trade names like "Wind Splitter". Many come from China. A windshield with a flip may be just be a marketing decision, saying to the customer "buy ours because it is different"; "ours is different that's why we charge more".

We have found that a "flip" style windshield can push up the air higher over the top, but with an very unacceptable trade-off, more turbulence and buffeting. Adding this to to all the other negatives, including our reading of the many negative customer reviews of incorrectly sized windshields (too short) with flips and flares, building a "dirty" windshield is not the way to go. Some flips are so radical, that they end up being 90 degrees or more to the ground. No way these work and for sure they will reduce gas mileage.

Radically changing the direction of a windshield curve (shape) for styling, performance or clearance reasons creates a "seam" that usually introduces a distortion at the seam. Many windshields with this seam also have additional flaws and mark-off introduced during the molding process at this seam. A windshield that is distorted at or near the top or side edges could create a safety issue forcing the rider to look through the distorted part of the windshield in certain riding conditions, like riding on roads with many elevation changes and curves. Riding on these roads should be "fun".

To independently confirm our conclusions, just check out the latest touring bike options from the OEMS, like the new Honda Gold Wing, or the new Yamaha Star Venture, etc. These new bikes have unquestionably been tested for tens of thousands of miles, many computer simulations and time in wind tunnels. These were built for long-distance comfort. If a flip or flare had any significant benefit you would see them offered. You may see them on smaller bikes with little windshields, but for sure they are styling decisions only, designed to convince new buyers the little windshield will perform like a larger windshield (it won't).

I'm not the best one to answer this one, but a local rider in BC did the old cardboard and tape, to modify up his windshield. Trying different styles, extra width/height, just playing with it and seeing what happens.

In the end, he added on another sheet near the top with stand offs, which allowed air flow between the two shields. If I recall correctly, the add on had grooves so that it was adjustable.

How about like suggested, air wings. Adding on the forks/pods, might be a lot easier than trying to figure out a curve in your shield.

Also, there is a plastic film on the OEM windshield, so be careful of it.

FYI - I fixed my buffeting problem by putting deflectors on the forks.

I added this to the winter windshield I use on my DR200se. works very well, no more buffeting.
