Hi, all. I installed the Givi bars on my MS a couple of days ago. Since then, I noticed a strange vibration and humming between 4000 and 5000 RPMs on the highway. All the torques are correct to specs. I have done some research and I can't find someone reporting this problem with this particular bike/bar ensemble. A lot of people have reported this with different bikes. Has any of you experienced this? Thank you!
