Riding and camping Northern California and beyond, since 1965!

Hi all.  I have a new 2024 1250GSA with less than 1500 miles.  I am having a serious vibration below the windshield that is loud enough to hear quite well with earplugs in and music off at speed.  I have tried holding the windshield but it doesn't make a difference.  It s fairly loud buzz rattle.  

Ant ideas or help would be appreciated.
