Apologize to the search nazies in advance ! I could not find a relevant response.
There is some back pressure when I have my Cee Baily Euro all the way up. I know some of you cut holes in your shield a.k.a Calsi style to reduce that. I am wanting to try that out, but first want to confirm that it does help, and second, what do you use to cut holes? Any other tips will be greatly appreciated.
EDIT: Apologize for being an A**. I retract the above statement. It is just that I have seen many people just run you down if you do not happen to do a search or find the right thread.

I can't help you with your shield question but if I may make a suggestion...
I wouldn't start out a question for help by calling some people a nazi, it tends to **** some folks off and pissed off people can be less than helpful.

Off topic, but I can identify with Awaz about the 'search nazis'. I don't dare post questions on this forum anymore....it never fails when someone does - there's an immediate barrage of replies berating the OP for not finding the answer buried somewhere in the threads.
-
Just curious...can you define the symptoms of "back pressure"
-
Wait... are you saying you don't post here anymore because the people are too tough but in this thread you posted about.... the people being too tough? I can't put my finger on it but there is something ironic somewhere in there I think....

I experienced the "back pressure" when I use the stock shield on my '09. When you raise the shield, it creates a vacuum behind the shield that kinda sucks your torso forward towards the windshield. The windshields (like the Cal Sci) which have a vent cut in to the bottom allow air to flow up the back side of the shield, eliminating the low pressure area.
-
Yes, that is exactly right. Looking at the hole, you would think that a column of air would come through and hit you in the abdomen but that is not what happens; the air coming through the windshield turns and flows up on the inside of the windshield to meet the air coming over the top edge of the windshield. It is really amazing to watch it happen- you can sometimes see a mist traveling well enough to see it but snow really shows what is happening. The snow flakes race right against the inside of the windshield and travel straight up all the way to the top. We would tend to think that such a big cutout would make for more air movement inside the cockpit but in reality it makes the conditions behind the windshield quite a bit quieter.

Where the heck have you been? Anyway glad you are back.

I have a Cal Sci, there is no back pressure. I had a Cee Bailey on my previous FJR and had back pressure so I bought a Cal Sci for it. The back pressure went away.
When I bought the C14 I bought another Cal Sci.
I don't care why but the hole in the windshield works.

On the matter of the 'Search function', I agree it isn't the best but it's worth a shot. Takes a few seconds and you can check for a quick hit at least. The second place too look would be the C14 Wiki FAQ area. Lots of good information there, but there isn't anything specific on 'back pressure' from a screen. I can tell you that right now. And while I don't have a good memory (I have my wife for that), I don't think that back pressure has been a subject per se since the new forum came to being. One thing that does irk me ( I don't like to be irked) is that a question (not this one) is being asked that was asked before not two pages back, so scanning the subject lines for at least a few pages back might help as well. It helps to have a subject line that is descriptive of the question being asked. Helps all of us find things easier.
Now back on topic. My stock 08 screen is great for warmer weather but it can rock my head back and forth (Brian, no comments from you ;) ) depending on the position. It also plays heck with my wife's head as well so I got a CB Euro. This helped and I don't have that rocking feeling anymore except from my mp3 player, which is as it should be. I do notice that when full up, going to full down, there is a position where I can feel my body being pulled forward a bit. I'm not sure if that's considered back pressure or not.

Not just for telling you to search, but telling you you basically suck. And locking the thread. Seems like most of the regulars in here are in prison or worse, and have a problematic backup of testosterone.
Really? I don't think that's true at all. I don't think any of our incarcerated members are posting from prison at all (possibly Poke, I'm not sure about him, maybe work release). ;) As for locking threads, I do seem to enjoy that somewhat (see sig line), however that is a last resort when the members are about to virtually throttle each other and NOT saying 'you suck' with a big loud Simpson's HA HA and then locking the thread. I've never done that, never even thought about doing that. I could make an exception to that though, if you really want me to.

And now, back to back pressure, please. This has been a nice digression and somewhat cathartic, but I do really want to understand back pressure as it relates to a screen.
Here are some links that talk about 'back pressure' that I found on the Web...

1) Start a thread on a negative note; one should expect that it will take turn in that direction.
2) Hostile Forum members? Sadly that does not speak well of some it's members does it?
3) Threads being locked? Jim moves lots of threads into locations that he deems more appropriate. 2ndly Jim does not allow threads that have degenerated into a waste of band width to continue.
4) Think we are being too PC? Too bad as this is an open forum (think family oriented) excessively fowl or hostile threads lowers the respectability level of the forum and it's members.
5) Have a complaint? PM the Mods it will be heard and addressed. You may not get the results you want but it will be heard and noted...

Our screens have a vent or space under the shield that changes a bit depending on where it's positioned. The side spacing on the CB Euro really changes due to the 'wings' it has on the bottom sides. All of that affects the wind flow and can cause pressure or buffeting I guess. I also have the gauge cluster shield that one of our members made available sometime ago. I may remove that and see if it changes anything. I know that if I had an inch or two more on the height I would be in quiet air but it would be a tad warm in the summer months. What I want is a shield that will give me lots of air without noise and buffeting in the summer and protection in the winter. I don't think I can get that, though.

Is this thread about a windshield or ZG forum etiquette?
The '10 has rectangular holes cut in the black part of the dash that address the back pressure, I can run my tall cee bailey's in the sky and its not an issue. Not sure of years before then but would suspect the dash looks hacked up on them too for air
edit: for those lacking thick skin:

The 08/09s don't have this vent, Steve. I think that Kawi realized there was an issue with back pressure/buffeting and added that to the 10's onward.

Interesting, but I don't think so......although somewhat intriguing in nature. I haven't inspected a 10 model onward so I don't know where those vents are and if they could be retrofitted to the 08/09 models without intensive heartburn. Could you post some pics of your vents, Steve. You like taking pictures and all that...

Actually for the dash vents like the '10 has. But maybe it can be considered a "multi-purpose" tool!
-
Wow ! was not expecting it to go 3 page ! But it is good read !! :) I like a bit of diversion on topics - not too much to invite the thread locker (*ducks*) - but enough to keep it interesting. It is more fun !
I will have to check out Steve's picture when I get home. At work, the picture won't pull up.
As most of you already stated, the back pressure I am talking about is the wind rushing in from the side and back and hitting me. Someone in the older forum mentioned the vent on the Calci prevents the vacuum that causes this affect. And then there was someone else that cut some nice looking holes on a VStream and was pretty happy with the result.
On another note, I do not know my materials well - is the Cee Baily Acrylic or polycarbonate?

I didn't know that the later models had these vents, I rode a '10 and didn't even notice.

I remember the last time someone told Kirby to do a search.... This is how I found him.
(http://i45.photobucket.com/albums/f82/BDF08012008/Kirbyoffthewagons.jpg)
Sure, you guys all think this is a big joke until you drive someone too far- I do not think you really appreciate how hurtful it is to have a complete stranger tell you on a public forum to do a search on a subject. In the end, Kirby tried to end it all by jumping out of a window on the 20th floor of the local bank..... Fortunately for all of us, he weighs almost nothing and given his shape, he just sort of twirled gently, all the way down like a maple seed. The last thing I heard him scream was "COOL" when he landed and then raced back into the building to do it again. It might not work out so well for the next person, especially if that person is really a person.

I see that Kirby is taking those blue pills, no wonder he's so stiff. (someone had to say it)

They are Naproxen Sodium, a generic brand of Aleve. My owner is too cheap to buy me the real stuff and says the knock- off brands are good enough for old rodents. I use them for the headaches I sometimes get after dealing with humans.....

On my '10, the dash vents that are supposed to address the back pressure don't seem to be enough. The only time I have
head buffeting is when there is a strong crosswind. So basically I have no buffeting problem, however when the windshield
(stock '10 with MRA spoiler) is all the way up it feels like someone behind me is trying to push my head forward and down, and in 20
minutes or so my neck muscles are screaming in protest. I'm going to try and make a CalSci type vent in mine and see if that helps.

Ok, I know some of you guys have 10's on up, where's the pics of the vents? What do I have to do, call a breakfast or lunch meeting in Fredericksburg and bring my own camera?

Per earlier comments cee bailey's is 100% aircraft quality, and the same material they use on the air force jet canopies they manufacture(http://i80.photobucket.com/albums/j180/stevewfl/avatars/biggrin.gif)

Wow, Jim is insistent, isn't he. ::)
OK Jim, since SteveWFL is ignoring you, I'll help you out. Ignore the dirty bike though, I got caught in one of those "surprise showers" (actual statement from the weatherman) three nights ago, and it was 36F when I rode in the next night. It's been way to cold to clean it up since then.

Thanks. I don't think it looks dirty. What I am getting at is how hard would it be to retrofit the dash plastic to add to an 08 or 09 bike. I take it there aren't any vents in the front of the bike under the screen?
-
The new vents in the fairing covers are directly behind the slots that the windshield arms travel in. As I remember, no, there are no additional intakes on the front of the bike, just the windshield slots (which are substantial).

Yes, that is correct. When looking into the slots vents from the back, you can see straight through, and out the windshield arm slots to the front.

Jim, the part with the vents in it is one piece all the way down around the new glove box. I don't think it would be as simple as just swapping plastic.
Another idea for modding the 08/09's would be to find a small dash vent from a car, cut the existing dash, and install the vent. Then it should look a little better than a couple of large holes.
Although, the viewing angle to see those holes is only from a low position, so really, only really short people or little kids would notice them.

That just caught my attention and I scrolled back. Apologies, I never ignore Jim or anyone intentionally. Great pics, I usually never miss a chance for a pic op either

It would be cheaper to buy a Calsci, then. Forgot you guys had that silly lockable box on the left side ;) . I could cut some vents but I would most likely wind up in the emergency room getting stitches.

Someone on the old forum did cut two 1" holes in his dash. Then he glued som black mesh on the inside of the cover to fill the hole. If I remember correct, it did help. :-\
-
I made a mod to the standard 2010 -screen by drilling 2 holes furthur down which allowed me to move the screen up by about 2 inches. When riding and raising the screen up , I found a definite push towards the screen caused by back pressure. This was solved by cutting 2 MRA varioscreen type holes in my screen using a slow speed drill for the corners and a metal blade on a jigsaw at slow speed to cut the slots. It does result in more noise though.
Attached is a pic. of the MRA screen

You could also just drill a series of smaller holes and not worry about the mesh.

Back pressure update
I made the cut in my stock '10 similar to the Calsci vent, and have tested it for a few months. It helps a little with the back pressure, but not enough. I debated ordering a MRA or a Calsci and yesterday I finally ordered the Calsci medium. According to the Calsci site info, it should be about 1 3/4 to 2 inches taller than my stock. If it's too tall I'll just cut it. If the new Calsci solves the problem then I'll continue to modify the stock 'shield to see if I can fix the problem with it. There seems to be considerably less material at the bottom of the Calsci, so maybe that will be the next cut on the stocker. It could be that the little flip at the top of the stock screen is what is causing the back pressure problem. If so then I guess it'll end up being cut down into a summer shorty, or perhaps become material for some home made hand wings. Time and money will tell. ::)
(Hmmm....it took me 14 months to update this, sorry.) :-[
