Wind management

Good morning all. Now that I have finally been able to put some miles on my new-to-me 2009 Vulcan Classic LT, I have noticed that, even with the windshield at it's highest point, I still get a lot of wind to my helmet, and once I get to highway speeds, it's like my helmet is vibrating a bit, which gets a little annoying after 30-minutes. I am 6'2" at 240lbs and I am looking just over the top of the windshield. My bike is pretty much stock, so stock seat, windshield, etc. with just a few additions like a crash bar with highway pegs, windshield bag and luggage rack, but not much else. So, I was looking to see if I should get an aftermarket windshield that I look through or what I can do to manage the wind. On my previous bike, a 1996 Yamaha Virago 1100, I had a Memphis Shades shield and I looked through the shield, and it displaced the wind beautifully. Of course, on that bike, I felt like I was sitting "in" the bike and not "on" it like I am with the Vulcan.

Anyhow, any suggestions or examples of what you all have done, if anything.

Thanks,
Dan

Raise the windshield. Re drill holes if necessary.

I'm not sure that raising the shield is the answer, as looking just over it is about the perfect setup unless you want to stop when it rains? Does your bike have lowers? On my Nomad the OEM lowers were too small anyway & close to ineffectual. I made some larger ones from a sheet of poly-carbonate.

Lowers definitely help...
Have DIY versions that are pretty large...
Helped a lot ...
But not the cure...
At speed your windshield creates a low pressure area behind it causing your head to bounce around...


You need a Goldwing style windshield vent...
Yep, cut a hole in your windshield !!!


Once you get by the squeemies of doing it...
It works GREAT !!!
Once I COMMITTED to the idea I'm EXREMELY GLAD that I did...
Your windshield, right now, is keeping you from fully enjoying you riding experience...
Or you wouldn't have started this thread...
Believe me I know...
Even with the addition of the lowers the windshield vent will alleviate ALL the buffeting and it'll be SMOOTH riding from now on...

Windshield vent... I like that idea. I don't have lowers, though that's not a bad isea either, but the windshield vent makes total sense. Is something like this what you mean?

That is odd. Out off all the non-fairing bikes I've ridden my 1700 Nomad has the least noticeable helmet buffeting (Because the windshield is closer to the rider). I can even wear ball caps with out them flying off usually. Maybe the lowers help to make a difference?

I did this Goldwing style vent a couple weeks ago on my Voyager. What a difference!!! Air hits me right in the chest and I don't seem to sweat as much during those short, in town errands. It's been in the mid to upper 80's a couple days already and with the exception of sitting at traffic lights, very comfortable riding. Highway riding seems a bit smoother and you can close the vent if it rains. I am very happy I did this!

My 900 with factory windshield + wind was terrible. Installed Kawi Lowers and it made a world of difference. I'm 6'2.

Wind management is more about directing air flow versus disrupting it.

Installing lowers makes a difference.

The adjustment of your windshield only has to be incorrect by a small amount to result in wind buffeting.

You need a second person to make the measurement for you. Sit on the bike with it upright and your weight compressing it as you would when riding. Using a level helps to ensure a correct line from edge to nose.

The top edge of the windshield should be level to your nose so that you are 'just' looking over the edge of the windshield.

Make sure the windshield is installed matching the angle of rake on your bike.

I adjusted mine just a smidgeon today (its raining today and the next several days so this is about all that I'll do with it until we have decent weather). I raised it up about an inch off of the headlamp to allow that bit of circulation to come through. I also tilted it back a little bit more so as to more closely match the rake of the forks.

And since I had raised the windshield up about an inch, I also raised up the lowers a corresponding inch. On my bike that gives an extra inch of fork travel without the bottom-most fork seals hitting the bottom edge of the lowers.

Now I have to wait to see what effects these changes have.
