Title: heritage wind buffering
Post by: bobrk1 on November 15, 2023, 06:50:38 AM
on the  highway  I get  a  lot  of  buffering  to  the  point  of  being  annoying  and  I see on YouTube  people  using  a deflector  on top of  windshield  and  lower  ones that  bolts  to  the  forks ,do they  work  as good  as  they  say ? I'm   looking  for  something  that  will  help  with  it on a  road  trip . thanks

Try a Klockwerks flare shield.  Not cheap but they are wider than the factory shield and flared on the top and sides to help with buffeting.  Offered in the FLSTC size and RoadKing sizes.

Although my Electra Glide is quite aerodynamically different than your Heritage, putting the "fangs" on my forks made a noticeable difference in buffeting that seemed to come up from the tank. Disclamer; my EG has fangs/lower tree baffle/fairing wing vents and a wider windshield, so I can't attest to which did the most. :nix:

On my 04 Fatboy I used the chrome fangs with the Roadking windshield  :up: the fangs made a huge difference

I went through this with my '14 Heritage. I installed an HD 'windsplitter' shield, and I was very pleased with it. I had hardly any buffeting.

Why doesn't HD design windshields that work properly in the first place? I went through this with a new bike last year and it was annoying. I am 5'10 and the Lowrider St windshield must have been designed for a dwarf.

Lots of wind may come under the screen. The size, shape and placement of the screen can influence pressure and turbulence around the screen causing buffet. As others have said, addressing the air flow below the screen using fork mounted deflectors, or fairing lowers, work well

The only screen/fairing I haven't felt any need to consider wind buffet coming from underneath is the original fxrp fairing. Bloody brilliantly designed fairing

I agree, on clear style windshields like on a Softail, a lot of wind comes from underneath and around the fuel tank. When I was riding my FXST out west and back I had a windshield on it, and added lowers to the upper fork leg to break up the wind flow. The windshield and lowers were from Memphis Shades.

These worked pretty good.

going  to  try  the  fangs, but the  buffering  is hitting  my  helmet  and  shaking  it drives  me  crazy  on the  highway .

Could be windshield height or angle of setup too impacting this

Look at a Clearview shield with the recurve.

I went through this for years.

My solution now is wear a top end FF helmet & leave the WS off lol 😂

thanks  everyone  I'm  looking  at  the  Clearview  windshield  and  you  can  get  it  with  a  vent  as well  as  the  flip at the  top, has anyone  got  it with  the  vent how  does  it  work , I  also  see that  you  can  get  it  down  low or up higher  wondering  how  it  works . thanks  again

I'm not familiar with this particular windshield, but I can tell you that the purpose of the vent is not so much for cooling, but to help reduce the low-pressure area behind the windshield, which is the primary cause of the buffeting.  I would definitely get the vent.

yeah  just  wondering  whether  it would  work  better  installed  lower or  higher  on the  windshield .

I have a Clearview with the vent on my 2013 Dyna, and it works great. I can't tell you whether the vent makes a lot of difference versus no vent, but I'm sure glad I ordered the vent. Keep in mind Clearview doesn't sell hardware, so you'll need to transfer the plastic to your own hardware. I have found that buffeting is partially related to prevailing wind. If I ride down a road and then turn around and ride back in the opposite direction at the same speed, the buffeting is different. It works well enough that I can't imagine riding without it.

hey Jim where  is the  vent located  on  your  shield, does  it  blow in your  face ,does  it  close  what  did  you  notice  if you  closed  it? thanks

Just an alternate suggestion. You say you wear a helmet, does it have a visor on it? A number of years ago I bought a new helmet that had a removable visor on it. On my first ride with it I couldn't stand the wind buffeting. I pulled over and removed the visor. It made a huge difference.

I've had helmets I couldnt wear because of noise and buffetting. On my 09 Heritage I have the fork fangs and a Freedom shield with a recurve, nice and quiet blastin down the highway.

Sorry, I haven't been following this thread. The vent is located just above the cross brace, as shown in the Clearshield web page photo. I wear a FF helmet, so I wouldn't feel any air blowing in my face. Most of the time I don't notice much difference with it open or closed, but when there is a lot of ambient wind, I do notice a reduction in buffeting with it open about halfway.

When HD developed the Rushmore fairing my 2016 was buffiting and uncomfortable at any speed. I tried every loaner windshield from the dealer with very little results. I,m 5ft 8in.
The klockwerks was best but not perfect with the 8 inch. I bought the 10 inch and very carefully cut the bottom off to put those wings lowered down to the fairing. It works! Have told the parts guy,(Who knows Klock). Maybe it could help others. Been 7 years, Klock makes good shields.
