| Posted : 04 Jul 2010 - 12:44 Post title : Laminar lip? | | I just got my Tbird back with a mid level screen and the buffeting is pretty bad (I'm 6' 0"). Am going to see if I can trade out with my dealer for a roadster screen, but that still may not be enough from what I've read on here. Have any of you outfitted your Bird with a Laminar Lip (I know that they dont make one specifically for our bikes, but I thoght that the Rocket III one might fit).
I had a Sprint a few years ago and the Laminar Lip added to the stock factory screeen helped quite a bit.
Thanks

| Posted : 08 Jul 2010 - 14:26 Post title : Re: Laminar lip? (Re: Jayhawk82) | | Jayhawk - I have the Laminar Lip on the large roadster screen. It help's, but doesn't totally remove the buffeting.
I am 6'1". The Roadster screen works well for me at highway speeds - up to about 60 mph, but on the freeway, 70+, it buffets - especially with a head wind. With the Lip, buffeting on the freeway is reduced, but not eliminated.
I'd like to try the shorty screen since all I really want is to keep the wind off my body.
The Laminar Lip from one of the VROD's fits the Tbird. I think it is H1141C, but check with them to be sure.

| Posted : 13 Jul 2010 - 14:42 Post title : Re: Laminar lip? (Re: EnGage) | | I have to say I find it rather amazing that Triumph could not get this accessory right. I had a large screen and lower wind deflectors on my V-Star 1100 and I was in a perfectly wind- and buffet-free zone of total comfort, even for my contact-equipped eyes, no matter WHAT speed I was doing!
Now on my 'Bird, I bought the biggest screen I could possible get, and I even bought the lower deflectors - as pathetically puny as they are! Wind- and buffet-free, you would think - BUT NO!
Now on my old bike, it too suffered from buffeting without the huge lowers it had. What would happen without them is that wind would hit your knees, bounce up, travel up your body, meet the wind flying over the top of your helmet, and cause turbulence.
OK, so I went to the expense ($50) to make up some bigger lowers for the 'Bird out of perspex. Better... But still not perfect. (I'll put up pics if anyone wants.)
So I was wondering what the hell is the problem with their screen, and I reckon I have the answer: Triumph were just a little too stylish for their own good.
The Yamaha screen is a flatter screen, which does not look as stylish as the Triumph one... But the problem with a slightly more curved screen is that the wind can whip around it better... And hit the underside of your arms rather than being thrown out a little wider with a flat screen... And travel up your body and face (drying out your contact-equipped eyes in the process) and hit the wind that is flying over your helmet, cause turbulence, and hence you have buffeting of the helmet.
Try it yourself - Run along a freeway doing 70+ miles... Feel where the wind that hits your body is coming from. If it is hitting some part of your body that then deflects it to your chest and goes upwards to your helmet, that is what is causing the buffeting. It is the interaction of these two air-flows that is rocking the boat!
Is it fixable?... I'll let you all know... I will continue to bugger around with the screen and lowers until I get it perfect. It IS possible! :)

I tried - as some have suggested - blocking the wind coming up my body with an arm, but that didn't seem to make any difference.

| Posted : 13 Jul 2010 - 17:57 Post title : Re: Laminar lip? (Re: Gonzo) | | Gonzo, keep us posted. Same problem, wind hitting knees and coming up under my helmet. I've done the same things. Added factory lowers which helped then had them made bigger at the local plastics shop which improved the problem again so I felt this was the right direction but now I'm stumped. I can't make them any larger because they'll hit the engine guards at full lock. Following the wind with my hand it now seems to be coming right over the top of the engine guards so I was trying to figure out something that might clamp to them.

| Posted : 13 Jul 2010 - 19:51 Post title : Re: Laminar lip? (Re: Gonzo) | | This is from the Calsci site. They put holes in all their windscreens. I have no experience with them, but perhaps someone else has and can comment.
Nearly all of our windshields have vents. These vents are part of the aerodynamic design of the shield, to reduce turbulence and noise. They are not there to make a flow of air on the rider. When you're riding on the highway, any windshield is pushing air away from the rider. This leaves a low- pressure pocket between the windshield and the rider. The air flowing past the motorcycle wants to drop into this low pressure area. If the outside air is allowed to spill into the area between the windshield and the rider, the result is turbulence, noise, and drafts. When outside air spills into the rider area, it almost always falls in a curved path, causing spinning vortices of air. These vortices are noisy and can cause the battering and hammering on your helmet reported by some riders. Our windshields and vents are designed to funnel air into the rider region to relieve this low pressure area and greatly reduce the tendency of outside air to spill in. The vents are designed so that the air coming through them is quickly dispersed, leaving almost no detectable air flow at the rider. Our goal is to produce almost completely still air on the rider with no back pressure.

| Posted : 13 Jul 2010 - 20:42 Post title : Re: Laminar lip? (Re: Thatch) | | Well, to be fair, the other posters seem more interested in larger lower deflectors.
I, on the other hand, am interested in putting holes in my windscreen. I've been watching this debate for a year now. I've seen folks say to go higher, lower, add lowers, make the lowers bigger, etc. Nobody after doing any of those has come back and said bingo - that's it. What no one has tried yet is putting a hole in the lower center part of the screen like can be seen here on their FJR screen:

(Re: EnGage) | | All sport and sport tourers have vents at the lower end of the screen. i didnt get any buffeting on the VFR and it was a short screen. The big bike producers spend thousands on wind tunnels to eradicate this problem. my short screen i have on the bird seems to do a good job , I get the wind half way up my helmet but I wear full face so that sorts that out. i do get a bit of buffeting when carrying pillion for some reason but i dont want a full screen so will put up with it. Having said that - I would like more wind deflection for my hands in winter, this would dramatically reduce cold hands. But how would i do that without making the bike look daft.

I actually think that might work! It makes sense to me, getting some air into the space behind the windshield so it doesn't curl around the edges to fill the low pressure area thus causing buffeting. Engage, I think you should try cutting some holes in your windshield and let us know how it works out! I'd do it myself.. but... uhhh... what if it the theory doesn't work?

This screen did not keep the wind off my helmet, but I don't care about that anyway.
I could try an after market screen, but I like the quick release feature since I don't use the screen once the temp is above 70 or so. Also, I don't much like the after market screens.

(Re: EnGage) | | Thanks to all of you who replied to my original post....I pick up the roadster screen on Friday and will check it out on the road. Hopefully its an improvement over the mid screen. If not, then will have to figure out next step.
By the way, EnGage, that's a great looking Bonnie. Do you still have it. I have a 2001 that looks a lot like yours, except I've chromed out the fenders in addition to all the other chrome that they had that year. Still gets a lot of attention wherever she goes.

1) No matter how many holes you put in your screen, there is ALWAYS going to lower air pressure behind the screen, so if that is the cause, the only fix is to not have a screen.
2) As someone else has pointed out in this thread, it's not like we are on a sports bike that has full fairing and thus making a perfect pocket of no air. We have wind coming in under the shield and off our legs and all over.
3) On my old bike, once I had it set up perfectly, the wind was pretty much non-existant behind the screen. Without the lowers there was all sorts of wind coming off my legs and lots of air moving around in there, so I would assume less pressure difference, yet that is when my helmet wobbled like crazy.

That is isn't enough. All that can do is limit some air hitting your face at best, but the air flow is still there that then flows up to your helmet area.
Here is the best test I was able to do on my old bike that told me I needed lowers:
1) Best done on a freeway with little traffic as you will not be 100% focussed on the cars! 2) Sit in your normal position. Ride along at speed (100kph+) until you start the head wobbles. 3) Lift your legs forward with your boots pointed straight up, to kind of make a flat surface, just underneath the bottom of the windshield. 4) Note if that makes a difference. If not, try changing the angle of your feet. 5) Once it does (it should) alternate with legs up and down, and feel with left hand where and how the wind is coming from, that is hitting your body and going up your chest and then to your helmet and over.
This test was amazing on my old bike, making a chalk and cheese difference, with lowers fixing it to perfection.
But on the T-Bird, this test only improved the head wobble, not eliminated it. And I still feel air getting onto my body and flowing up over my helmet.
The old lowers from my V-Star are about to get hacked up and bolted to the Bird. They are not just flat. They have a few folds on them that in my mind would deflect air in a way that would make a "bigger bubble"... Will most my results. :)
NOTE: Appreciate any and all ideas and comments. If I don't agree with you, does not mean I don't appreciate the input. We might yet stumble across the answer with all of us doing these wacky tests. :)

I know I am going to sound like a broken record here... But my old bike was comfort perfection. I could ride that thing for 10 hours in a day without any straining of neck muscles, or blurry vision, or headaches, or irritated scalp, or itchy ears - no matter what the wind conditions, rain, hail or shine.
Mind you I spent a *fortune* getting it that way over a 5 year period! But I did get there, and I will do the same for my Bird. Just hope it does not cost me as much or take as long. ;-)

Now this idea I think has some merrit.
The screen on my old bike was too tall, so I got it cut down so that the top line of it was below my vision line. To be exact, I want to see ALL of the car in front of me that I would generally drive behind at a safe distance when doing 60kph.
Now I have the big Roadster screen on my Bird. Once again, it is too high. I hate looking through the screen, especially when it is raining, where I think it is dead set dangerous, then!!!
Once I have it cut down, I am thinking that will improve things in terms of head wobble too. Why do I think that? Well I can't explain it exactly, other than the closer the initial jetstream is to the top of my helmet, the better it would be than *trying* to fly it higher over my head which then leaves that "empty air" on top of it that could allow for turbulence.
Again, will let you know my results. :)

Too high? Really? I find it awfully short, and I too like to look over. Mind you, I'm 6'3" so I guess they can't please everyone. If it was about an inch higher I would still be looking way over it. I don't use it all the time, but with the bugs and cold weather we have here I can't imagine being without it on a long ride out on the highway.
My Kawasaki has an adjustable windshield and I found the buffeting a lot less with the windshield as high as possible. I suspect that might be because of what Engage was talking about... allowing air in through the bottom to fill the low pressure area immediately behind the screen to reduce the air flowing in from the sides (i.e. buffeting). But I'm no aerordynamicist so I just speculate!
Engage, you need to start cutting and hacking at your windshield to give us a report!

Who out there has the summer (short) screen?

I' m still interested in the air flow thing and shall keep an eye on your progress . I will go for full wind protection but just for long haul rides. i ride four to five times every week (not work) so my short blasts don't bother me too much. And i like the look of the bike without lots of windows on it. I will however be looking at hand deflectors for winter, I suffer real bad cold hands since leaving a fared bike and no amount of extra money on gloves gets rid of the problem. Need to find deflectors that look right .

Yeah, for short runs to work or into the city on a night ride during summer, I'm happy to ride with no screen. But for Winter, or any multi-100km ride I want to get home without feeling like I've been hit by a bus. :)
As for the cold hands - have you tried the heated grips? Or I have seen heated glove inserts?
I've seen wind deflectors for grips and I can't say they ever look good to me. About the "best" I've seen is what you could describe as soft "booties" for the grips made of similar material to an Ugg boot. They were big enough simply slip your gloves hand in, and have room to operate the levers and all the usual stuff. Black on the outside and wooly on the inside. Didn't look *good* but then you knew what the purpose of them were without looking gay like big black plastic things you see in front of BMW GS bikes. :)

Heated grips still dont warm the tops of your hands and I dont want to look a knob with big mit things (even if they do sound nice and cosy !!!).

Triumph's doesn't use a knob - they have a two-position button. Not sure it would be any easier, but I'll find out this fall when I install the heaters.
