So I've got a 2020 CB650R (inline 4). Dealer did some work on the crankcase cover and now it vibrates like crazy and makes a weird new whining noise that gets louder as RPMs get faster. Can't hear it when the clutch is pulled. Dealer took a look at it and said they couldn't hear anything and that I'd just have to deal with it.

Need some advice on what to do next. When something doesn't feel right or sound right......
