My experience with Glee and MRA Vario

[bosnjo]

Hi,
I tought just to add my experience with buffeting and wind noise on my Glee and MRA Vario screen. When I got my Glee, 2nd hand, it already came with that screen and without OEM screen. I'm just guessing it's MRA Vario. It says on the bottom of the screen: MRA type WVM KBA90512. It has a little spoiler on it.
From the day one I picked almost no buffeting but a lot of wind noise. When I say a lot, I mean it's huge. Now I use earplugs that are so thick that I don't hear the engine at all but still hear some wind noise. The screen was mounted on the highest position and no spoiler adjusting would change anything.
I'm 6.2
Then I removed the spoiler and hinges completely. No change at all. Then put back the spoiler. Today, riding to my work, I rised my head, looking for the quit position and found one with complete silence (I mean, normal wind flow almos impossible to hear in my helmet). The problem is, it was a lot higher then normal riding position. Then, at work, I lowered the screen to it's lowest position but had no T8 to remove the spoiler. On my ride home, the noise was still the same but the silent spot was just at like 15cm head rised above normal riding position. Again, playing with spoiler position made no difference. At home, I removed the spoiler completely and replaced top spacers with 4 washers so the screen is now tilted a bit more towards me.
That's it so far, tomorrow's ride will show if it's any better.
I just have nothing else I could do to lower it more and I'm afraid I'd be still needing a bit more of lowering. Also, lowering it more would ruin completely the look of the front of the bike.
If that doesn't work, I'm thinking of puting it back high again and making (or buying) big spoiler and go from there. The problem is, when I was looking for the quit spot I tried lowering my head as much as possible but the noise was the same.
I'm running out of ideas but I'll still wait for tomorrow and see.
Basically, what I need is clean air flow, as like I didn't have the screen. That's what I'm looking for but riding without screen is out of question for the sake of the look of the bike as well as cutting it down, as I don't have any spare screen.
Ideas?

Thanks

OK, a ride to work this morning showed some improvement but not enough. Now I need to rise my head 5cm to get to a silent spot. Still missing some more lowering/tilting.
Already at work, took the screen off and put as less as possible spacing on top screws and as much as possible of spacers (original spacers and plastic washers) on lower screws. I can not tilt the screen any further because the screws are already tightning it at angle so I can't even tight them as much as I'd like to.
Here is how it looks right now:



I'll see how it is on my ride home this evening. With this, I can do no more on spacing/lowering. The only possible, and more radical step to take is to drill new holes on the screen so it can go even lower.
I'll see and post the experience here.

Well, yes, the last position gave me clean air flow, the one I wanted, but now I encounter new problem. High air concentration is being sent to my neck and then inside my helmet and to my eyes. Had to slow down due to tears in my eyes this evening, on my way home from work.
Back to square one and drawing board.

It's the holy grail of motorcycle riding, I've yet to find 100% quiet on any bike I've ever owned or ridden. If you want clean air on your lid your screen and mirrors need to be in a position where they won't influence the airflow hitting your lid at all.

[bosnjo]

Yes, you're right. Mirrors are not an issue anymore. I have Aprilia ones now on extenders, so they're out of the way. Tried today few km's without the screen. It's perfect but I don't want my bike without the screen, that's out of question.
I'm developing new idea, though a strange (if not stupid) one. I found out that the spoiler on MRA Touring screen does nothing about the wind noise. It's because the noise is produced by the screen itself, I mean by the stream coming out of the top of the screen, passing bellow the spoiler. That is the reason I had no luck changing position of the spoiler.
So, I was thinking about the spoiler behind the screen, not at the front of it. My spoiler would not do the job (too small) so I'm now investigating few things and will see what comes up.
Basically, I need extension for my screen. I have no idea how tall is OEM L2 screen because mine came with MRA Touring already. MRA Touring is 40cm. I made some measuring and found out that screen for my hight needs to be 60cm, giving me some room to adjust (maybe the best option would be 60cm in middle holes). But, there is no 60cm screen for Glee. The best I found on eBay was Puig screen for Glee and it's 49 cm. I don't want to spend big cash for the screen that would not be high enough. Now I'll try to build extension, something like a spoiler, but behind the screen, that fully extended would provide 60cm of full hight of the screen.

The Givi Airflow seems to get a number of good reviews, it's this one:

For my hight, Givi Airflow would still be the problem as main screen is still too short and the spoiler (additional screen) is separated too much from main screen. My problem is always the airflow from the top of the main screen and the only solution I see is to have spoiler behind main screen.

OK, here is my ugly solution. But, it works. No buffeting, no turbulence. Some mild wind noise up to 60 km/h. From 60 to 100 km/h noise is a bit louder but if not on the trip, no earplugs needed. On 120 km/h I'd need earplugs. Tried 160 km/h - earplugs needed, head lowered and no turbulance at all, just wind noise.

This "ugly" solution is temporary, until Puig Screen arrives. The hight of my Frankenstein (screen) is the same as Puig one for glee. So, Frankenstein will do the job waiting for Puig.

The Puig Screen has arrived today. The rest at:
