When I bought the bike off Steve it came with an MRA screen and airfoil. Although it was a massive improvement on the standard screen I had decided to try a Givi Airflow adjustable screen.

Only issue is that the Airflow is only available to certain bikes and the TDM900 isn't one of them. Found out through various forums that Givi sell all the bits as spares so decided to take the plunge.

 

First thing was to buy a std screen which I picked up on ebay for £20. Ordered the Givi bits off ebay and they arrived next day for total cost of just under £60.

 

So here's a short rundown on the fitting in case anyone else feels the urge.

 

This is what you get. Airflow screen and fittings to attach it to the original screen.

 

 

First thing is to mask up the area where you are going to drill. I hadn't got any decent masking tape so used duct tape.

 

 

I then loose fitted the fittings and measured the distance between centres.

 

 

Marked the screen centre line and then made a template of the basic distances on paper and transferred them onto screen.

 

Once that was done its just a case of drilling the 2 mail holes. These are 20mm dia and it was the only thing that caused a problem as I didn't have a 20mm dill or step drill etc. I made do with a smaller step drill that went up to 12mm and then opened the hole using a rotary grinder (with great care!!!!!)

I fitted the parts to line them up and slid in the screen to make sure they were in the correct orientation and then drilled the 2 smaller holes that hold things to the screen.

 

 

The screen slides in and is clamped in place from the rear.

 

This is the lowest setting ......

 

... and this is the highest

 

 

Haven't had a chance to get out yet and I'm away all day tomorrow so looks like friday. Will let you know how it goes.

That looks interesting, 

 

I've always wanted something that was adjustable, seems a pretty simple system. 

[palexxxx]

Looking forward to seeing the results.

eagle

could you post a couple of pictures from the side please (with it up and down)

[gbob]

That's a classy job, as opposed to the diy effort on my old vfr.....

 

 

[Eagle6]

Most of the bikes that have the option of the Airflow have a steeper screen rake than the TDM so I'm going to try it out as it is and then make some brackets to push the top of the screen forward if necessary.

 

 

 

 

 

[ramo]

thanks for that eagle,

 

looks good

 

is there much flex in the bottom screen if you press on the deflector part when its in the highest position? 

 

let us know what its like when you've been for a bimble

Hopefully tomorrow (Friday)

Nice job but I'd watch out for signs of the rubber well-nut fixings pulling out of the fairing due to the extra leverage exerted by the big screen (the bottom fixings tend to pop out first. FYI, my solution using Palmer Products adjustable brackets, standard OE screen, and my home-made fairing panel is pictured below.

Looks intresting...but looks like there will be pressure from the OEM screen building up under the bottom edge of the AIRFLOW. Won't that try to lift it or channel air between the 2 screens?? Following this with interest.

I've been considering a 2 layer screen for a while.

 

Using a standard screen and then mounting a 2nd screen (I've got an MRA bubble, and a Yam touring to play with) approx 10-20mm ontop of the normal screen.

 

Much like Palmer screen above, but more Carpe Fettle style.

 

The standard screen I've got has already been drilled in an attempt to reduce the eddies (spelling) on the dash side, which I reckon is the one of the main causes of the buffeting.

 

However with SWMBO nesting in prep for the twin's in a few weeks "fettle time" is very much limited...I keep taking things off the "jobs for Adam" list, but it keeps growing

From what I understand the layout is designed to provide a channel of air that that is compressed and faster that travels up between the 2 screens and pushes the air coming over the top of the outer screen higher thus reducing the buffeting and noise. At least that's the theory. We shall see.

I had the Palmer kit on a Tiger 1050 and was disappointed how flimsy it was. They even supply (for a price) a bracket that bolts to the inner body of the fairing to keep it from flapping. So I was not impressed.

Sounds pla

Sounds plausible. If this works there'll be a stampede for AIRFLOW kit.

This is what I'm hoping for with my fettled plan...

 

I'll get photo's once I've made some progress...no doubt Mr Henty's expertise will be asked for re mounting the 2ndary screen...

[scrumpymike]

Yep, the idea is that having two smooth and parallel (or almost) surfaces produces 'laminar' air flow by squeezing it through the gap. This faster, more focussed air stream passes more cleanly up over the rider's head with the right fixed screen and is more easily re-directed when combined with an adjustable screen.

 

"I had the Palmer kit on a Tiger 1050 and was disappointed how flimsy it was. They even supply (for a price) a bracket that bolts to the inner body of the fairing to keep it from flapping. So I was not impressed." Surprised to hear you say that Eagle6, but each to his own! My 9er is the 3rd bike I've fitted the  Palmers to and I've been delighted with performance and quality every time - even without the added rigidity of the optional accessory bar (intended as a sat-nav carrier).

OK, just been out to local dealers for some fasteners, so done about 40 miles of various roads.

 

All these comments are based on this one ride which took place in some real blustery conditions and in Lincolnshire it's pretty flat so there's no hiding place from the wind.

 

Good and not so good news.

 

Good!

The Airflow is totally stable, hardly any movement at all up to about 90. The only time I noticed any movement was due jolting over bad road surfaces which was more down to whole fairing moving than just the screen. It works as it's designed with the 2 flows pushing up the air higher. Easy to adjust on the move with the over-centre clips. Even on it's lowest setting it was an improvement. It was on a par with my old MRA but the air around the helmet was smoother. Range of positions is infinite. 

 

Not so good.

As I mentioned in a previous post, it's designed for bikes with a steeper rake to the original screen and to work more efficiently the TDM screen will need to be angled up more. On it's highest setting air was hitting me just above the visor. One consolation is that those with a taller/touring screen may benefit more than those with standard screen.

 

Next step is to bodge some brackets to push up the back of the OEM screen about 3".

As promised - Part II.

 

I've done about 300 miles with the original setup and although it is an improvement it could be better, and I mentioned previously the Airflow is designed for bikes with a more upright screen configuration.

 

2 brackets and a support brace later and we have the next step.

 

I think the bottom brace may be lifting the screen slightly too high but I'll see how it goes.

PS: I'm going to use some 10mm threaded bar to make a brace across the top brackets and possibly use it to mount the GPS.
