Touring Screen

Help Support Triumph Motorcycle Forum:
Couple things- remember that popular Vetter fairings of old had small round adjustable vents that could bleed in air to the low-pressure area in front of the rider to limit "buffeting". I have seen similar on BMW and Gold Wing screens. Also, there are a number of "YouTube" videos that explain air flow and buffeting. I had an '83 BMW R100RS that came with a tall screen. The fairing did a superb job but at certain speeds the high-pressure airflow that went up and over the screen would get sucked back into the low pressure area in front of the rider and just constantly bobble my helmet so bad vision was blurred. But you stayed dry in the rain! I experimented with 1 inch reductions in screen height until it became tolerable. later, I rode an identical bike that had a small rectangular vent in the screen, maybe 1x 4, and with it just slightly open- no buffeting and vastly reduced wind noise while the area around the rider stayed calm. So, my thinking is- that air displaced by the screen is gotta go somewhere and at some point it will come back together to try to fill that hole. "Laminar flow" is what I believe it is called. And the bigger the screen, and the higher the speed, the more problems you'll have trying to manage it. My experience is that a way to relieve or equalize the low-pressure area behind the screen and in front of the rider is some type of adjustable air bleed. And, importantly, what works for the rider may be horrible for the passenger- though I stayed dry in rain on that BMW, my passengers invariable got wet backs and shoulders.

I have a Memphis shades. it was awful. head shake so much that I could not see. the above venting has always helped on every bike I've had. but hard to find for a cruiser. my Tiger has a Madstad it is perfect. my FJR was basically designed with the gap and double airflow like the Madstad. My connie had a Rifle Fairing and it had the low air gap and was quiet air. I have been searching for a double screen for the America or a vented single screen or maybe destroying the Memphis with a saw and making a small screen behind the big one. I can't find anything premade. Madstad told me if I was ever in Florida they would use my bike and make me one for free to have real results and feedback. I am never going to be in Florida with my America but if someone were I would buy the screen when they sorted it out.. that guy is genius in my opinion.
note: I added lowers and it helped a lot but not enough to be great.

I am going to have to do some cleaning up of my cut holes so don’t judge too harshly. I’m gonna try it befor I spend a ton of time sanding the rough edges.
Two holes cut with a wind deflector behind. I work in aerospace but know nothing of airfoil so I’m just guessing based on previous good wind shields
I’ll put on bike and let ya know

The first few rides I had on my 23 tiger 850 were windy days and very disappointing . I was seriously considering a quick divorce on a bike that everyone one of the fifty u tube reviews described as the best thing since sliced bread .
While riding at hiway speeds in wind there was an obnoxious vibration/buzz whenever leaning during a curve or if a side wind blew the bike off the center of the tire . I checked the tank side panels and a couple of other spots to no avail but one day I caught the windshield in my jacket some how and when it sprung free there it was . The buzz was a result of the little wafer springs that allows you to move the screen up and down when compressed .Those springs have no dampening qualities . The tires on the bike were also new releases from one of my favoured suppliers , no bad reviews on those either .
I replaced the offending little devils with a couple of pieces I found in my junk drawer , probably from when I deleted the clipons from that red bike . They were made of pretty hard rubber , looked and worked perfectly except the screen did not go up and down with out the help of an Allen key . This was not an issue , when I installed the tall Triumph accessory w/s on the 800 it was adjusted as high as possible . When I sold it 10 years later it had never been adjusted again .
This little change improved things , a lot . Then I was reading on some forum about the tires . Apparently , when new they had a front end vibe when ridden off the tire center . I was about to install the slightly used Dunlops from the rack but held on and the original tires improved with each long ride . Having said that , they are not a dirt tire in the least . A 95-5 at best , a good rain tire maybe.
To own a Triumph it’s best to be a good tinkerer and possess a healthy dose of stick to itness .
IMO

I have purchased a cheapie screen from China. First mistake was to order the smoke and not the clear. Smoke is like a second dark pair of sunglasses when you are already wearing sunnies. I need to look over the screen, which I have set up that way after first ride. I have it slanted back a bit so I can look over it. First ride it offered more protection than the Dart Flyscreen (smoke) which looks good but offers no help. When it finally stops raining and I can get another ride in I will report back.
I think smoked screen purchases are encouraged because all Harley riders order dark ones then then want them tinted even darker . With those guys black is the favourite colour , maybe some of you have noticed this too . Stay with the clear ones , they match with any colour bike .

I always have to look over. Never have liked sitting behind and looking through. Especially when the rain hits on a trip
Looks great but you really should ditch the green helmet…
I think brooke may be referring the the watermelon husk on the dog's head.
