wind screen buffeting

[norcal rider]

I get a fair amout (a lot) of buffeting off the wind screen in all postions. Is this just me or my helmet? Kind of doubt it. Any one else have this issue? Any good fix out there?

Other than this I love the bike. Yamaha did a great job with this bike. That's why this seems like a big over sight seeing how well everything else is sorted out and so well done.

I get a lot of buffeting too. I've tried raising and lowering the screen and different helmets. It's just buffeting the upper portion of my helmet. If i lower my head 2" it goes away. Some people don't have this problem but some others do. I will probably buy another screen in the not to distant future.

Having said that, I didn't realize how good of a job the stock screen and fairing does until I rode my KLR to work the other day (it was feeling neglected). Talk about buffeting! At 75 mph I was really getting slammed. The Tenere is so much better.

On another subject, I'm headed to the Lost Coast in a couple of weeks. Any must see places or must ride roads that you are familiar with?

Thanks.

I am 6' 0" with a 32 inseam and ride in the low seat position. Previous motorcycle is a Gen1 KLR that I installed a TCI winshield.

Adding a windshield to the KLR was huge. Many would make jokes about it but they had never ridden with a full windshield. I know some of the Tenere riders talking about wind buffeting come from a full windshield motorcycle like FJR or Star and are used to a lot of wind protection. I know Carl and he does not complain about anything so if he is experiencing wind buffeting believe him.

I do like the construction of the stock windshield and personally don't have a big issue with the stock windshield but I have played with it to find positions that are better. I have mine in the upper position and I am experimenting with a more forward position. I added a couple 3/8" spacers (nuts) between the bracket and windshield to get a more forward position. I had to buy longer bolts to do this. If there is a difference it is not much but I am going to double the spacers to see if there is more change.

Before buying a windshield I would buy a MadStad or WASP adjustable bracket. Had a MadStad on a DL1000 with a stock windshield and found the lowest most forward position to be very good.

I think there can be two types of windshields. A summer and a winter. The smaller summer windshields are probably not going to give the water protection on the outer portion of your body though would allow more air in the warmer months. The winter windshield is something you can hide behind and stay dry but that might not be what you want for warmer weather.

The concern I have with adjustable brackets is they push the windshield away from the motorcycle and can let water and bugs under the windshield.

Another concern with tall windshields is the "sail effect" when wind comes from behind or the side and tries to steer your motorcycle. The Tenere seems to be less effected than the KLR and I am guessing that is because of 100 lbs and better stability.

Just my thoughts on windshields and adjustable brackets that I have given too much thought about. I am not against them and do use them but I do not expect magic.

CalSci is 15 minutes from my home and I was there the other day with a couple other Tenere riders that have their windshields and they are happy as clams with the CalSci windshield. I will probably test one within the next two weeks before leaving for a short 10 day trip.

I'm 6' 4" and have the oem tall screen. Puts the blast directly on my helmet. Think a wasp or madstad is in my future. Also might consider a TT Vario adjustable. Had a laminar on my klr but don't see one on my S10.

Other farkles come first, so I'll just wait and see.

Just installed a 24 inch Parabelum windshield and it is awesome. I am 6 ft 1 with a 32 inch inseam. I still look over the top with ease. The buffeting is gone and very quiet. Called the order in and had it 5 business days later, great customer service. The shield looks great on the bike without looking to big. Great improvement to the bike.

Would you post a couple of pictures of your 24 inch Parabelum windshield?

Thanks,

I'm 5'8" and had the same problem...I went with the TT Touring screen
http://www.twistedthrottle.com/trade/productview/5688/821/

I still get a little bit over the top....which is ok for hot days when I want to get more helmet venting. I can also hunker down an inch and get out of the wind wash.

I've gone the opposite direction - a smaller screen.

I ran a trial with just a bit of cardboard as high as the supports for the screen and found the buffeting had disappeared.

As a result I have mothballed the stock screen and bent up a checkerplate screen that is half an inch higher than the supports.

The pics below show the OEM screws through the checkerplate into the stock rubber wellnuts on the supports.

...and that reduced the buffeting?

Interesting...is that because the wind now hits your chest? I would have expected less coverage means more wind.

Actually, in some cases, there is less buffeting (turbulence) without a screen at all. This usually happens when you are in clear air. A car in front of you creating turbulence usually screws that up.

Sportbike screens sometimes have openings at the bottom which are designed to direct air onto your chest. This takes some of the weight off your hands while riding at speed, lessening fatigue.

Screens tend to direct the air around you, but always result in turbulence..... hopefully not at your helmet, but far behind you.

This might be a dumb question, but can this screen be mounted in the lower mounting holes? I'm 5'10" with a 32" inseam and was thinking I'd rather go with a taller screen like the 24", but it would be nice to be able to lower it if it's too much in my line of sight in the high position. Hope that makes sense.

yes it can be mounted in the lower position i just have it in the high one in the pics, i think if your 5"10 and run the seat on the low position you might want a 22" screen but it mainly depends on whether or not yours a sloucher like me ::013::

I would have been happy removing the screen altogether if it reduced the buffeting, but those 2 screen supports would remain and they looked a little lethal. Plus the little panel protecting the back of the clocks looks a little flimsy.

A few years ago I had a similar situation with a BMW K1200R - the mean and nasty brutal naked - that came with a "touring" screen when I bought it. After just a few km of riding I had to stop to remove it.

To protect just the back of the clocks I mounted a Yamaha MT-01 headlight protector at a crooked angle and happily rode around.

I'm sure that going to the larger screen mentioned in this thread is also effective, but with my current solution the buffeting has disappeared, the airflow now hits my helmet cleanly.

I'm with you on your screen and why you do it. I think some of the guys were surprised with your choice of materials. It very well could be that the diamond plate surface has the effect of dissipating turbulence. Maybe you're really onto something with that.

The "K' looks pretty cool with that cover, by the way.

I am definitely a sloucher. I also run the seat in the low position. So I guess I oughta go with the 22". Thanks for the input bloke.

 

[norcal rider]

I don't mind the air flow or the size of the screen, they are both about right. It's just the buffeting. It's enough to be really annoying and even headache inducing.
Has anyone used the touratech adjusment bracket?
What are your thought with that if you have.

You would think with all that light out front you wouldnt get any wind lol.
