This helmet buffeting is back.
If I go faster than 65MPH (in still air - less speed with a headwind) I get that upstream behind the windshield. I can't take it for a full day anymore, and I have an 8-day trip in July.

I can't figure out how to tilt it, so I am thinking of cutting about 4 inches off the top.

Has anyone else done this?

Did it help?

(If it won't help, I may just have to suck it up and buy a smaller one like memphis shades. I'd hate to waste the $$ though.)

For $200 I can get http://www.bakerbuilt.com/cruiser_bikes.htm

But that is most of a new windshield.

If the air is coming up from below, why would you chop the top? You can make some "air dams" from some fairly inexpensive materials ... plexiglass (or higher $$$ Lexan) ... home-made aluminum flat- or angle-bar brackets ... #10 stainless steel machine screws with self-locking or acorn nuts.

The air is being sucked up from below because a vacuum is created when the windshield is pushed through the air. The "air dams" you create need not be easy to see, either. They can be horizontal planes ... perpendicular to the bottom edge of the windshield, or parallel to the ground ... just about any configuration that will disrupt the air flow. The biggest headache will be taking the time to make cardboard templates to ensure adequate clearance at full-lock.

I've got a Memphis Fats on my 05, and I get quite a bit of upflow behind it also at speeds in excess of 60 mph

Have you tried removing the shield and ride with a Full face helmet?
With a full face, you could run the sport fairing. That will keep the air off your body and the full face will keep you head dry and bug free,

Just a thought.

In weather above 60 degrees and not raining I do run without the windshield.

But running for 8 long days is going to kick my butt without a shield, and I know I'll hit some rain on this trip.

Worst case is I look into the detachable touring windshield.

I don't care for the looks of the fairing, and it is not compatible with the Custom models.

the detachable touring windshield.

Could not be happier!!!:banana

Very well protected overall, can ride all day with no strain, comes off for around town or security.:whisper

I believe you won't be sorry if you buy it for your trip!

Good Luck

Here's a "how to" on chopping a windshield...hope it helps...

I have had the same problem with my yamaha seca 750 and especially when there is a car in front of me, I try to position myself just under the windshield so it shields me from the draft. But on my sportster I sit lower and there is no problem at all for me, I basically sit in a vacuun. I have the Slipstream hellfire windshield on both bikes. I am 5.5" and I ride with a full face helmet.

Good luck, Cameron

Problem virtually solved...
Myself and another lister both recently posted elsewhere about this problem and solution. Adapt a pair of RoadKing/Softail chrome wind deflectors. I have the HD Quick Detach compact shield. One extra hole drilled in the deflectors, longer bolts, 3/4" chrome spacers, and the whole setup of shield and deflectors comes off together in seconds. On an otherwise fairly calm day, I can ride freeway speeds in a half helmet without earplugs for wind noise, and the turbulence that used to bounce up off my knees and slap me in the chin is now a comfortable breeze. See my gallery, linked below, for pics. I believe I also saw a similar set of chrome deflectors and color matched plexiglass lowers for Memphis Shades shields in the J&P catalog, and National Cycle makes clamp on plexiglass lowers/deflectors, also in J&P.
