Lower Fairings causing more buffettng?

so i added some ebay lowers to my street glide last week, and after a few runs back and forth to dallas (avg speed 75mph) ive noticed that im getting a lot more head shaked WITH the lowers than i did without them. any ideas what to do to fix this? I've got a set of the batwing-extension wings im gonna put back on, see if they help, and after that, swap out my windshield for a different one. also going to play with the vents, wide open vs closed.

any other ideas why the lowers are giving me more head shake on the highway?

ive got the fork baffle up front, and a 9" LRS ultra shield

I've got an 8" Klockwerks shield, Fairing air deflectors and lower fairings and get very little if any buffeting.

I ride with my lowers off in the hot summer and put them back on during the cooler weather months and I don't notice any difference with buffeting.

Can't speak to knockoff lowers, but I never noticed that with the factory ones. The majority of the buffeting on a pre-Rushmore Batwing bike comes from airflow around the fuel tank. If you were to put the deflectors from the Road Glide on top of the crash bar and trim them so that the fairing didn't hit them, you'd see a big difference.

The only other thing I found that worked was a Madstad windshield. They're not shown on their website, but they exist. They remove the low-pressure area behind the Batwing and make a HUGE difference in buffeting and wind noise. When it was adjusted right, I could light a paper match at 60mph.
