2006 windscreen mod

[OneTrack]

I am in 2 minds about the mirrors, but I do see what you mean because I noticed it myself.

If they were changed for R1 or R6 mirrors it would look good and certainly more sporty than the FZ6 does now.

I could be wrong, but the 07 FZ6 mirrors look shorter and better angled than 06 and earlier FZ6's mirrors. Might be worth a comparison to see how they'd look on your bike with the shorter screen?
Great writeup! :thumbup:

I never really noticed a difference with the Puig racing for the 07. The only thing I like is that it is way easier (mean I don't have to crouch as far) to get into a tuck and have no air at all. I think thats what they mean by "racing" screen.

When tucked the top of your helmet is inline with the top of the screen and the wind rolls off the screen then helmet then back. I'd think thats more aerodynamic. But then again, who's going that fast that often to necessitate the advantage ......

The Double Bubble racing screen does not make any appreciable difference. I know because I have one.

I would not like to have ridden 3500 km bend double under the screen.

When you lower the screen you do not get blown backwards off your bike. There is a greater pressure of wind but it is constant and is not uncomfortable.

I would love to hear some comments from someone else who has done this mod just so that they can confirm my results and opinions.

I think once someone does it and finds what I am saying is correct then the floodgates will open.

Would riding without the windshield be a good way to test out the possible outcome of the smaller size windshield?

 

[steveindenmark]

Yes it would and someone has already done that which made me realise that the smaller screen would work.

You do not need to test this method though...the mod I did works..I have done all the testing for you...cut the stock screen down and you will see it works.

Thanks for all the input, i'm not questioning your results what so ever, i'm just pondering the effect it might have for me since i'm really tall, 6ft6 (2.1meters tall) i just would not want to become like a "sail" with all the wind resistance, haha

 

[urbanj]

I'm not doubting you. I agree 100% Like I said I didn't notice a thing in wind turbulence change when I put the Puig over stock. I'm just saying that's what I think the reason is for having the "racing" screen.

Even with out a wind tunnel to prove it, I would guarantee that being able to tuck under the screen and the wind flowing over your head is way more aerodynamic than the wind hitting you in the face and chest. BUT, as everyday street riders and riding the bikes we do i don't think we are seeing the benefit.

now on a 1000 where you can reach the top speed of about 300km/h and reach the FZ6's top speed like you weren't trying, I would bet you'd like to be tucked in behind something substantial. That's all I'm saying. That's why I think it's the "racing" screen.

I have been thinking about this turbulence from the wind shield real hard. The bad part is not the wind it is the turbulent wind. The turbulence is caused (all of this is my opinion) by wind tumbling in to an extreemly low pressure area behind the screen from a high pressure area in front of the screen. Cutting your screen down reduced the low pressure area. Making the top round instead of flat spread out the turbulence. I have a Lip on my stock wind shield but still have a lot of turbulence at high speed, it is just higher than it was.So what I did was to try to increase the pressure behind the screen. On the 04 there is a small Yamaha symbol stamped in to the wind shield near rhe bottom of the screen. I drilled 4 holes in to the screen about the size of a dime around that symbol, one above, one below, one to the left and one two the right. The turbulence is reduced by doing that. I have found that I have an area of about 6 inches of turbulence above the screen. I was riding at 80 mph and found the turbulence reduced. I put my hand between the screen and the back of the speedo housing and could feel no wind at all from the holes I cut. I don't know where the air is going that comes through the holes but it felt dead calm to me. Tomorrow I am going to either cut some more holes in the screen or make the ones I have bigger to see if the turbulence can be reduced more. My advice to people who are looking to get rid of turbulence and get out of the air is to find screens with vent holes in them so the air can get behind the screen. I noticed the stock FZ6 screen and the double bubble racing screen are air tight ( close to it) from top to bottom. If you are going for a tall screen to deflect air then get one with vent holes to reduce turbulence.

I have both the standard windscreen and touring windscreen and the only difference IMO is that the wind turbulance gets transfered from your chest to your helmet. I looked into buying a seperate spoiler for it but this was not available in the same colour as my (darker) touring windscreen.
On my previous bike (a diversion/Seca) I had a windscreen which had a kinda postbox slit in it about 3/4 up, this worked excelent, no turbulance at all (well non you could feel). I am now tempted to try doing the same thing on my touring windscreen, and if it doesn't work just simply take it down a notch and do steve's windscreen Mod.

Mike I think you've got the right idea as I have read that the turbulance is created by the low and high pressure regions meeting, so you have to try and eliminate the vacuum behind the windscreen to reduce the turbulance.

Ok, the suspense is killing me... did you get the result you wanted - less turbulence?

Good picture. The man is part of the screen. The racing screen is about the arodynamics and increased speed of the bike. The point of the FZ6 is that it is not set up like a racing bike it is set up for comfort. If you want to put your chin on the tank and become part of the screen then get a racing screen.

As I have said before in this thread. Even I was suprised by the difference, its massively better than the stock or the double bubble racing screen.

I put drag bars with about 3 1/2 inch pull back on my bike. I put the grips on so that there is about an inch and a half of bar sticking out of the end of the grips. I got a clamp on mirror and cut the rod on the mirror down to 4 inches long then clamped it on to the piece of bar that sticks out past the handle. The inside edge of the mirror is about 2 inches from the end of the bar. The mirror is maybe 22.5 degree angle up from the handle bar ( half a 45). I think it looks fantastic compared to the stock mirrors and the mirrors only cost $9 each.

I would love to see what it looks like

ummmm not to quibble Steve but I re-read the thread and didn't see your evaluation of the result. (EDIT) Sorry - I was looking at it with a different view. When I clicked on "More replies below current depth" I was able to see the rest of the thread. I'm glad it worked because I've been pondering a new screen to reduce turbulence also. Thanks a ton for the HOW-TO!

 

[formula154]

I know. I will see if I can come up with some pic's to show.

This thread is a little strange. Some post seem to appear then disapear. I'm not sure what is going on.

Good job with the mod. I'm not sure if I could cut that straight.

I've had the stock shield, the tall Yamaha shield and the Puig DB on my 2004 and they all suck.... The noise is crazy loud even with the earplugs that I ride with. The FZ6 is by far the loudest (wind noise) street bike that I've owned.

The tall Yammy shield made some freaky turbulence on my 6'3" body, so I sold it. The Puig is somewhat better than stock, but I hate how badly it is made as compared to the stock shield (e.g. no molded hooks for the mirror boots, bad fitting around the screw holes, etc.)

I've been wanting to try a cut down stock shield, or try cutting a NACA style duct into the bottom of the stock shield.

Hmmmm.

Steve thanks for the how-too. did this last weekend. Looks great and much better than the givi tall windscreen that I had. I ride on the hwy a lot about 200km's a day for work, and although it is windy it is constant and more than livable.
The stock and givi windscreens I have seem to concentrate the turbulence and unfortunately if your sitting upright it will concentrate on to your head. After cutting it it seems to be just constant wind over the whole upper body rather than just on my head.

 

[formula154]

Turbulence to the head is harder to take than in the bod. With my stock wind shield the turbulence tried to pull my helment off my head at 55mph.The stock is flat. That concentrates the turbulence. Just cutting the screen more to a point will spread it out over a wider area and make ir much more livable.

How tall are you guys? the wind off my puig standard screen (same size and shape as stock) hits me in the shoulders. feels perfect.
