strange sounds

[ssridesred]

I put a Clearview +11 on with the hope that I'd magically get away from the turbulence. Well the stars did not align and I still experience an annoying turbulence. Compared to the stock windscreen the turbulence went from a gentle wobble to a sharp wiggle. I should say that this is at 55-75mph indicated, below 55 there was no irritating turbulence. Also I'm 6'1" with a 32" inseam and I've tried the no wind screen and the +4. So I am thinking about how the shield could be modified to reduce the turbulence. One thought I have is to cut the top lip off that is suppose to flip the air up. I am thinking this would smooth out that airflow. This would make it similar to a rifle shield. My second thought is to cut a vent in the windscreen like you see on some sport bikes. I guess this helps reduce the low pressure on the backside of the shield which should allow the air to flow higher above your head. Has anybody tried the above mods or something similar? Any success escaping the turbulence? Steve

No suggestion, but I'm glad to see this post. I'm the same height and was planning to get the +11 screen (hoping for more protection during winter commuting), so I'm interested in the outcome of this. Good luck. You may want to check a company called Saeng (www.saeng.com, I think). They make a variety of "airflow management clip-on devices" and advertise in the back of Motorcyclist magazine.

Steve, Went through this on my DL. My solution was to take a Memphis Shades shield from my previous 650 V Star, bend a little plastic at the bottom of the shield to fit the front of the bike, and then bolt a lip (2" x 8" plastic) to the top to deflect air. I also cut a triangular vent hole at the base of the stock shield to which this M Shades is bolted to. I'm very happy with the result. The vent hole reduces the vacuum behind the shield and the lip deflects most air over my helmet, but allows some to equalize the pressure at this level. Because the affair is bolted to the stock shield, I call it my Frankenshield. It's not the cleanest look around, but it works. My head sits in calm air. My eyes are about an inch or so below the top of the lip. I have it braced with rubber hose around the bolts. It's not as solid as the stock shield, but has stood up to some nice trip and is good to about 160 km/h. If you have any other further questions, fire away. On another note, I'm new to the group and contemplating a KLR. I'm presently looking at all my options and following this groups discussions for info. Did the same when I bought my DL. This info exchange is very helpful. Plan is to sell Super Sherpa and replace with KLR. I'll miss the go-anywhere ability of the Sherpa, but need something that will carry myself and my wife on short trips. this will be the bike I take on vacation and loading this into the back of my Titan will be much easier than the DL. Sherpa just doesn't have the carrying capacity I need nor the power to ride hwys two up. But I have been having lots of fun in the Dunes area near town. Keep up the good discussion. I'll be listening.

I've tried the stock shield, the Kawasaki tall shield, and the +11 inch Clearview, each result worse than the previous. At the suggestion of a member of this list I mounted a Memphis Shield Demon to the handlebars - improved but still not "clean." I then added a Saeng Winglet to the top of the Demon, and voila . . . Looks unusual, but I can see over the Winglet and the airflow is quite smooth. I am 6' with a 32 inch inseam. BB

A buddy did an interesting mod on his windshield, which is on a Beemer F650. He clamped along the top for leverage and used a heat gun to bend the windshield outward, creating a 2 inch lip. Then he ground it back to about 1.5 inches and smoothed it all up. Looks great. He said the only trick is to NOT overheat the plastic. FWIW YMMV and all the other caveats because this was him doing it and not me. Oh, yes, the result was not only great looking but also works perfectly. Keith

A friend modified his shield with a 6" strip of plexi. He attached it about 3" down from the top edge with three or four velcro spots. The 1/4" space created by the velcro lets air through to the back side, thus filling in the lower pressure and stopping the back draft. Says it works great.

Thanks for the great response on the list and via direct email. So far the success stories revolve around adding some type of winglet to help redirect the airflow. I spoke with Clearview today they favored trying to control the airflow by reshaping or modifying the top of the shield. They thought venting it would weaken the shield too much because of the relative narrow base. They also mentioned that reshaping the shield with a heat gun would be challenging unless a jig is used to obtain a uniform shape. Good ole' trial and error will be my plan of attack focused on smoothing out the airflow or kicking it higher. I'll start out by adding stuff to the top edge of the shield to see if that is enough to change the airflow then it's onto winglets. Breaking out the saw will be last. I created a folder for anyone that would like to post their windscreen mods. I posted my first attempt of cutting down the turbulence with the stock windscreen. I tried placing a series of dots on the stock windscreen and that just seemed to lower the airflow and the turbulence was the same.
