Setting screen height

[Tank]

As mentioned in my post yesterday - I just grabbed myself a DL1000 V-Strom.

One of the bits it has is a Givi screen.

First attempt with the screen wind came across and it felt like I have Mike Tyson tapping on the top of my helmet.

Lowering the screen helped a ton - although there is still some buffering.

I 'could' (and will if necessary) try each and every setting and ride, but was wondering is there a 'rule of thumb' about setting the height?

Like - should be at nose height etc etc etc

Any help will be appreciated.

There is a lot of information on StromTrooper http://www.stromtrooper.com/ about screen adjustment. Basically, you need to adjust it so that your helmet is fully out of the wind flow, or fully in it. The worst place is if the wind hits your helmet at ear level.

I have fitted a Madstad Bracket http://www.madstad.com/s.nl/it.A/id....=7&category=67 as a cheap way of quickly adjusting the screen for any riding conditions. It allows you to adjust screen height as well as angle.

Not really as everyone is slightly different shapes and heights and wears a different helmet, but as Jantar said, either have your head totally in the windstream or totally out of it. It's the grey areas where the turbulence is.

BD's Rule of thumb (for tall men):

No screen: Excellent

Small screen: Tolerable.

Big Screen: Devil Spawn.

Doesn't the rule apply to big or small men?

The issue is more related to speed:
Up to 110kms better without a screen
110 - 140 put up with some turbulence
140 + - small screen and tuck under it

Oh my Gawd! Well congratulations (first) and sorry I can't help you with the screen thing...

This is the advice I was given by a wise and helpful KB member... (copied n pasted)

Adjusting the screen is simple really.

Try this.

You need a length of wool (red works best ) and some cellotape.

Cut a piece of wool so it reaches from the top of your screen to almost touching your helmet when in your normal riding position.

Cellotape this to the top centre of you screen.

Ride off down the road at 100kms, the wool should float in between the high and low pressure zones, this is what sets up the buffeting your experiencing.
You need to get your helmet out of this disturbed airflow
Adjust the screen up/down and sometimes changing the angle also helps, untill the wool floats just above your helmet.

Job done

Hope this helps

I like it! Thanks for that. I hope to get a few runs this evening to give it a try. Bling well deserved (please pass onto the wise old man who gave it to you)

Yeah Griffin, great idea, I'll give it a spin myself.

I've played around a lot with the tall fairing on my BMW and could never get it quite right. Eventually as a pure experiment borne out of frustration, I forced back the rake - which seemed counter-intuitive. And it worked.

The roiled air tumbled and produced turbulance behind my helmet, instead of both sides. Job done.

My mate has a tall Givi on his VStrom 650 plus a small adjustable lip at the peak. The result is nearly perfect - no wind noise or turbulance. However he sees the road ahead through the screen so needs to keep that clean.

Take the screen off, and ride the motorcycle how motorcycles are meant to be

Smaller guys can get 'in the pocket' with a big screen at normal speeds. Giraffe heads no show.

And how do you know that motorcycles arent 'meant' to be ridden with a screen? Horses for courses dude...

Hey Tank, as one of the other guys said, Madstad brackets are the way to go..fully adjustable height and angle with easy thumb screws.. Had some on my DL650.. come to think of it, I removed them when I sold it, so they are probably in the garage somewhere..

Let me know if you are interested and Ill try dig em out..

It's a slippery slope -- I've seen it -- first they start out with a screen, next thing they're adding 'leccy starters an' fuel gauges an' hydraulic disc brakes an' more'n one cylinder an' CDIs an' fuel injection an' then they've got a car, dunnit?
