You basically made your own Air Bender. Good job!

I have seen that too but, it is only made for the GL1800's not the GL1500's... This is what you are referring too...

If you look on ebay you may still find them available for a 1500. Its just a guess but due to there age they might not sell so many for 1500s. I thought about it but just didn't care for the way it looked on the bike. If I rode 2 up all the time I probably wouldn't care what it looks like as long as it worked though. Its an interesting accessory. :)

Since this thread was included in the newsletter I thought I'd better post an update.

First of all, thanks to everyone who posted. Lots of helpful ideas.

I've put a Puig adjustable wing/deflector on the top of the stock screen. This has eliminated the worst of the buffeting. It's still not ideal but it is certainly tolerable.

I'm not really a fan of this solution though as I am still looking through the screen. I hate looking through the screen. I find it annoying in all kinds of circumstances and feel that it can be downright dangerous at times. That's just my opinion of course, I hold nothing against anyone who might disagree. To each their own.

I think the ideal screen would be the Madstad. My 2nd choice would be to cut down the stock screen. The problem is, I'm not sure if I'm going to be keeping the bike long term and I really don't want to sink any more money into it (Madstad) or reduce the resale value (cut down the screen). For now, I think I'll keep riding it as is (once the temperature drops a bit of course).

Cheers!

It's a nice piece of cosmetic but, does it REALLY work? I would love to see some aerodynamic diagrams or video of the device in the testing phase(s). Have you had a opportunity to ride with one installed to notice a real difference or, know anyone whom has one installed?

I was just posting a link for Fatboy46 who asked about them. I dont know anybody who owns one and dont have one myself. Haven't seen one in person either, just in videos and photos.

I'm really not understanding why these would help with wind on the passenger either. Below is the only video I could find with info on it. Seems like these are mostly for blingy goodness :)

For the 1800s looks like you can get it customized to say what you want (maybe same for 1500s). Sorry not trying to derail thread! :)

So, I've been riding the new bike for a couple of weeks and I'm getting pretty frustrated.

The wind protection on this bike is the worst I've ever experienced. There doesn't seem to be any smooth airflow anywhere in or around the cockpit. My 2007 KLR650 has less turbulence. FYI, I'm 6'4" with 34" inseam.

My '97 has an OEM vented screen and it's basically useless for me. At the lower positions I get vicious buffeting, like my head is in a Home Depot paint can shaker. When I raise the screen it helps to soften the buffeting a bit, but the back pressure in the cockpit is a big problem with the wind actually pushing me FORWARD towards the screen and bouncing my head around in a very tiring way.

I borrowed a Puig adjustable air-foil that clamps onto the top of the screen to provide extra height and adjustable angle (https://puigusa.com/en/tuning-motos/vis ... onsivetab2.

It helps, but in order to get rid of most of the buffeting I need to raise the shield all the way and put the Puig in a raised, upright position as well. This means I'm looking through the Puig and the top of the OEM screen is right in my eye-line. Very annoying and possibly dangerous in rainy/buggy conditions.

The bike also came with Air Wings (2 piece deflectors mounted on the lower fairing). They're great for getting air and staying cool, but whenever I turn them to direct air towards me, the buffeting goes crazy.

It seems that I may be stuck looking through the windscreen, which I REALLY don't want to do. I'm considering removing the windscreen entirely and seeing what that does. Anyone have any experience running with short screens?

Sorry for the ranty nature of the post. :? I just got back from a long ride and I'm rather annoyed... Basically I'm looking for any suggestions on improving the airflow without resorting to a tall, look-through windscreen.

Cheers

Back in the old days we used to install a product called Lareamar lip on top of the windshield to handle that problem. Actually I just saw one A minute ago they're reselling them . Anyway I happened to see a windshield with the lip Built-in called knock werks. I am coming off a ducati and I have a expensive helmet that is the cuts the wind so the factory windshield really doesn't bother me.
But when I saw the werks windshield it was so beautiful and it flowed with the lines of the bike and I will absolutely buy pretty over substance. I'm 6 1 34" inseam and I bought it purely for looks in a 12" I always want the windshield to be a couple inches below my eyes. It looks stunning on the bike but an additional benefit is it really cuts the wind and I don't have any problems whatsoever with wind directed on myself.

I haven't used one, but it makes sense. Objects with blunt-shaped rears have a lot of, not sure what the term is, backdraft? If you drive an SUV with the rear window open, you'll suck in exhaust. If you open the rear vent/window on a pickup truck, air blows in. Many convertibles have rear wind deflectors to keep the wind from blowing your hair forward. I used to have a convertible, and this was very annoying.

I can verify what Oakback says.
I have a pickup truck with the slide-open rear window.
Air does not go OUT through that window.
It blows IN. And if you have any dirt or leaves in the
bed of the pickup truck, it all ends up in the cab, which
is why I rarely open that window.

That's what I wanted to see, science, the dynamics of physics... Now I can make a intelligent educated decision whether or not to buy.

Seems like something you could mock up out of plywood and strap to the rear rack to test...

Figured I should update this thread for posterity.

I finally bit the bullet and dropped the $$ on the Madstad screen. The folks at Madstad were very helpful, answering my questions via email promptly and thoroughly and even throwing me a discount code because I'm a repeat customer (I have one of their screens on my KLR650). I bought directly from Madstad, but they are also sold through Cyclemax. The shield shipped in just over a week and FedEx had it at my door in Toronto in 2 days. As a plus, I got a follow-up phone call from one of their sales people a week after I got the shield, just to check in and see how the install went and if there was anything I needed help with. Very impressed.

Between the included instructions and the DIY tutorials on this site, removing the old shield and installing the Madstad was a piece of cake. Everything fit perfectly.

I've put about 1000km on with the new shield, including a few hours of highway cruising at 110km/h. The buffeting is as gone as it will ever be on a motorcycle, airflow has improved in the cockpit (which is to say that there is actually some decent airflow in the cockpit) and best of all, I'm looking well over the top of the screen.

It's a huge improvement and I actually want to go for a long ride now.

For anyone who's dissatisfied with their current shield, I whole-heartedly recommend the Madstad windshield system. My only regret is that I wasted most of the riding season going back and forth on whether it was worth the $$. It was :D And to be fair, it's not that much more expensive than many fixed shields.

So which shield did you get (height and any tint)?

I got one recently ( 12", light tint). I wanted a medium tint but they were out of the material and were not sure how long till they were going to get more.
I am still not sure if I should have gone with the 14" (I am 5' 11" with a ~28-29" inseam), but the 12" seems to work. I can still move the base part up a little more to get another inch or so out of it I think, and will try it the next time I have the front plastics off.
Regardless it is worlds better than the Tulsa Tall I had on it before (more air flow and not looking through the screen).

16" light grey. I'm 6'4" and it's what they recommended. Barely any tint, which is fine with me, but the edge of the shield is grey and doesn't glare like the clear shields can when the light is at certain angles. I have the base plate as low as it'll go and the shield is raised about 1" using the brackets. I'm really impressed with the airflow. I can actually feel the air moving through the vents in my jacket and helmet.

I was going to ask this question, so thanks to blupuphor for already asking and to you for already answering.

I've thought about getting the dark tint because I think it would look good on my black/charcoal bike. However, I've also been paying attention to how much I do look through my OEM clear shield when at slow speeds, parking lots, and about to stop anywhere. During the daytime it might not be an issue, but I do some riding at night. Especially, when coming home from work late at night.

Since the shields themselves aren't too expensive, I've even thought about getting a dark and clear to be able to switch them out as needed.

The light tint is not an issue at all, I would imagine medium would not be an issue day or night.
Dark, just depends on how high you have it set, how dark it is outside (i.e. city, rural or country) as well as how often.

I was going to post on this subject early on but John covered it well pointing you to the Madstad. I'm glad you chose to spend wisely and found the satisfaction you needed in the Madstad.
Post a side view of the bike with it on so we can see the angle you like it at.



Back 8 years ago when I was getting ready to buy a new windshield for my 99SE that I had at the time and planned to keep, I had been scouring the forums posts of trying to get rid of the buffeting problems. I tried the cutting down of the stock shield to no avail. I knew I didn't want a taller shield as I had already experienced an instant translucent windshield one night hitting a cold valley on my 83 Aspencade and had to stand up to see over the white out windshield...
I thought seriously of the Windbender but was low on funds for my next trip and went with a new Vstream w/recurve top to save $150 from the price of the Windbender. That was not a wise decision. The recurve was just below eye level for me and the distortion was bad and the buffeting was still there as well as had a high speed flex of the shield in winds that put me into a tank slapper a couple times. I didn't get around to replacing it before the bike's demise by cage battle.......
After healing up I bought an 08 1800 and almost immediately found a used Windbender and have loved it since putting on in 2013 and have 130,000 miles behind it. Summers I have it at the lowest position, winters I do raise it a bit to cut the direct cold air but still keep it below my eyesight lines.
I didn't hear about the Madstad until 3 years after getting my Windbender so I haven't stepped up to get one but I have liked the tilting adjustability idea of the Madstad.

Since I got it in 2016, my '89 GL1500 has had a vented SlipStreamer "Tulsa Tall" on it, and I liked it so well that I got another one to replace the first I had broken. I'm 6' tall and do not experience this buffeting and it looks sleak on the bike, but I do have to agree with John (AZgl1800) that it is a bit warm in the summertime even with the vent, and for me, the top of the screen hits me in the chest just below my collarbone while mounting the bike. As for rain, I've never had any problem seeing unless it was a fine mist or fog. That tends to collect on the screen. My wife complains of getting air though, but I don't get it when I ride in her seat! My only problem then is that I can't reach the handlebars!!! :o


Autocorrect has become my worst enema!
