While I wait on the fabrication of the mounts for making MS deflectors rotatable on top of the highway bar. I had to play with my idea...
I used the GL1800 mirror wings to get an idea of how the setup will work. The pictured deflectors are difficult to rotate and are smaller than the Memphis Shades deflectors but they gave me a good indication of how the final setup will work.
I'm happy to say, having a deflector on top of the highway bar SERIOUSLY cuts down on high speed buffeting. Also the felt heat was never too bad during the entire time with them "up", I could have rode around without issue. But with them in the "down" position I had free flow of air and was completely cooled when moving. I'm excited to get the Memphis Shades on now, I think I finally nailed a solution. More to come

"down"


"up"

Really happy for you PaiN.

Crap Pain, I just realized your highway-bar-top deflector idea is useless with my FORGED BARS. I fully suspected from the first hint of it that you'd be on the right track by pursuing that...I've always suspected it's the wind coming just over the top which causes the majority of our buffeting. I have a picture in mind of a device I'd like to fabricate for the forged bars, need time to work it up but I bet something like this would work a champ for us forged bar folks - even better if it could articulate like your plan.

Not exactly like your drawing but I have seen a deflector mounted on the forward top edge of the forged bars.
If memory serves there an XC review on one of those old "Videos by Andy" reviews where you can view them on the bike.

Yeah Ja; the back surgery I had a couple of years ago left me with foot drop on my right foot. Coupled with a previous surgery that did the same thing to my left foot; my ability to hike with my dogs was taken away from me. I'm not complaining; just making a statement of fact. Unfortunately that lack of exercise has caused me to be fatter. The good news is I have lost 10 lbs and working on losing more.

This is also why I had so much trouble walking at Sturgis.

Ahh....understandable.

Got the Memphis Shades mounted on the highway bars tonight. As this project went on, Carl and I decided to make the mounts more simple. We did away with the tension screw idea, because the clamps only go so tight and will never close tight enough to lock on the bar. That said, the clamps grab hard enough, that when cinched closed they will not move at any speed the XC can go, but can still can be rotated by hand for moving the deflectors up, down or in between. I took a short test ride and they seem to do an excellent job.

From the short ride I took they seem to block a noticeable amount more air in the "up" position then they did mounted on the forks, I'd imagine with the Close-out in it would be like having a full set of hard lowers. With them down, its full air flow heaven :)
 
#23 ·
So the highway bar top mounted wind deflectors were a good idea with bad implementation.
Good because they do do an excellent job of buffeting control when up and allow full air flow when down.
Bad because the deflectors could not stand up to being moved and both completely split on the drilled outside clamp.
Sorry about the crap pic my batt was low, I had no flash or focus but the split can be clearly seen.


I ordered another set. Now I'm trying to decide if I'm going to put the new set back on the fork mounts or just use one clamp and keep them on the highway bars.
 
#24 ·
The new deflectors arrived and tonight, there was no way I was not running with the new idea I had.....:nerd
I installed this set with one clamp this time and all the way "inside". My intention is to not move them up or down but to leave them up to control buffeting. I did a short ride with speeds up to 65mph and they seem to work well. Most of the ride was in town, light to light stuff and I didn't notice any excess heat in the 88 degree temps. I had decent air flow once rolling.

Well done. Looks great!
 
#26 ·
Let's hope it works and holds up this time....I won't be moving them this time so they should be fine. As for looks, the new position is more "stealth" I think they look better not sticking out so much.

I've been working with a guy over at the ***, who saw my bar mounts. He's got custom fork covers and has been looking for a way to control the buffeting. Anyway, he had his XC over 100 yesterday and said he can't believe how well these deflectors work.
 
#29 ·
Hey Pain, were your first deflectors acrylic or Lexan? I don't believe they would have cracked like that if Lexan, but have to say your simplified mount looks sleeker. I gotta get busy and do some experimenting for a version that'll work on my forged bars.

I believe there is a top mount deflector available for forged bars. I'd help you look but I'm at work right now.

I have been meaning to post these pics for a couple weeks. I have an XCT and it's too hot for me in the summer with the XCT lowers on. So I take them off for the summer. Heat problem solved, buffeting problem created(even with Madstad windshield setup, though it greatly helps). So after talking to PaiN, who gets ALL of the credit for this solution, I added the GL1800 mirror wings on to my crash bars. Problem solved. Takes care of 95% of the buffeting, but still allows some air around them and I get plenty of air to the engine and my legs. The best part of this solution is when I am not on the highway, I can easily swing them open for full air. Genius!! They work great! The only difference in my setup is that I installed them in front of the crash bar as close to the fairing winglets as I could. This way it blocks the air earlier, before it can get under the fairing and up to my head.

Really cheap fix, around $60, and doesn't look TOO bad. I did have to buy 2 locking nuts for the wings mount. For now, I just use the bracket that holds the lowers in place. They are a little big, so I just wrapped some electrical tape around the bars and they are not staying snug.

My bike is now complete for summer riding.

Thanks again Mike.

Update:

Found the perfect clamp for my setup. The hard lowers clamp did move a bit. Then I tried a couple clamps PaiN gave me. They also moved on me at 80 mph. Both required electrical tape to build up the bar thickness. So I decided to try the Kuryakyn P clamp. Works even better than expected as the nut I was using fits perfectly in the clamp. No build up needed. Clamps on very snug. I thought I would have to rig up a different fastening system to hold the deflector on to the clamp., but the M5 8mm nut is perfect for the job.

Looks a lot better too.

@davefarias.....that setup looks very familiar LOL

I can't tell from the pictures if you are blocking more air or feeding air into the low pressure area behind the fairing. Which are you doing?
 
#36 ·
Having used that setup...its definitely "blocking"
 
#39 · (Edited)
@davefarais Dave, do you have a link to these P clamps? With the larger Memphis Shades deflectors I have mounted I'm also getting some movement at highway speeds. I was going to fit a rubber piece under the clamp to tighten it up but I like the Kury clamps better

Here they are. Kuryakyn Universal P-Clamp Mounting Bracket - RevZilla



I ordered the 1 1/8"-1 1/4" as our crash bars are 1 1/4"

The clamp also comes with a decent size bolt for connecting whatever you want to connect to it.
 
#41 ·
Thanks Dave....but $40 for a pair!....even I can't justify that much for clamps when I can use a thin piece of rubber to fix my current setup

Nice find boots ;)

Ya! Nice find boots!!!! arrrrrgh

Oh well. Sometimes you find the deal, sometimes you don't.

It's all good.

Oh, since I had the bike on the lift I was looking at it up close and a thought came to me of yet another way to improve upon the already great wind and buffeting control scheme I made up ...stay tuned for this one ;)
