Thanks everyone. I ordered some aftermarket brackets with 5 star reviews saying they are more heavy duty than HD ones. I think with the seal, poly bushing and brackets, it should cut down most if not all the excessive shaking.

 

Got the brackets(updated version). Installed the brackets and windshield seal and it cut down about 40% of the shake. Had to rotate the fairing speakers a couple holes over to line up the bracket. Much better, and havent put the handlebar bushing in yet. Should be great after that. Im already happy how it is

Thanks again

 

My 2010 SG had a super annoying vibration on the left side of the fairing. I figured out that it was the speaker and took the outer fairing off to examine it. The screw that holds the metal brace to the speaker was missing and with the brace barely touching the speaker, it created the vibration. A single screw fixed it.
