The other day I saw a fix for wind buffeting coming under the windshield and over the tank on a HD Compact QD windshield.

With stock shield the buffeting coming over the tank was really bad. It would always blow the cigarettes and lighter right out of my shirt pocket when I got over 50 mph. After this modification I ran the bike up to 80 mph and returned home with my cigarettes and lighter still in my pocket.

Could not find the original link, but thought I would show you what I did to stop the buffeting coming over the tank.

This was a very cheap fix. $9.95 for a 1” x 1/8” aluminum strap stock, 8 #10 screws and 8 lock nuts. And a spare piece of 1/8” Lexan I had laying around.

I removed the bottom 2 screws on each side of the wind shield and use 4 new screws to attach aluminum strips that extended several inches below the bottom of the windshield.

I then cut the Lexan to shape and used the screws to attach to the extended aluminum strips. I also put a backing strip of 1/8” aluminum to support the lower Lexan deflectors.

 

That's a great idea. I like how they are attached to the windshield so when the shield is removed, so are the lowers.

Thanks!

 

I did basicly the same thing several years ago, has held up fine, and it is nice that its all quick detachable.

 

Funny, I just posted my complaint about this on one of the other treads. I just got my HD shield last weekend, and while it helps a lot, the buffeting is not good.

So really, those little pieces reduce buffeting that much? That's great info! Thank you.

 

I have always been puzzled about this buffeting problem, I think alot is just positioning you shield just right. However what little I did have, dissapeared when i added the lowers. I truly can ride a 75mph with a baseball cap (bill forward) and not loose my hat.. However turning your head to look behind you, Is not a good idea.

 

That is very nice! How did you get the curves to come out so good?

 

Nice work, good idea.

 

I first made a cardboard template and then I cut the Lexan curved shape on my band saw, then sanded the edges with 220 & 320 grit sand paper. I did not remove the protective covering on the Lexan until I had completely done with the job. There were a few trim cuts I had to make on the Lexan to get them to fit better. If you do this don't forget to flip the template over to make the other side deflector. I learned the hard way. First try I had 2 deflectors that fit the left side well, but not the right side. Back to the bandsaw to cut a right side deflector.

I really like the way RonnR's looks, but I did not have the guts to drill additional holes in my windshield braces.

The way I did it you can always remove the straps and the original windshield straps will look as if they had not been touched.

 

The grass is always greener I guess, I like the way yours look.
but as a side note I didnt drill any additional holes, I just took a 1/2" longer bolt thru the top hole on the M/S Lowers,
and thru the bottom hole of the M/S windshield..
I did ,however put a 'cut to size' peice of sheet rubber between the 2 as to prevent scratch or rub marks on the windshield.. Then found a couple rubber plugs for the bottom holes on the lowers.

There is also another deflector you can try...forget what it's called now but there was a thread on it. Think it was called a fork baffle or something like that. This is also a stock Harley touring piece:
