My 2022 FJR has the same whine that you described from the day I bought it new. I call it a turbine winding up sound. I asked the dealer about it and they test rode it and said it sounds like a FJR. Had he throttle body synced at 4000 miles (it was almost perfect). 13 months later and 8000...
I got mine from Malcolm Smith Motorsports in Riverside, CA. According to the Yamaha Dealer Inventory website, there are only 3 left in California. 1 in San Diego, 1 in Pasadena and the last in the Sacramento area.
I sold my 2003 Honda Goldwing and purchased my 2022 FJR on April 1. So far and have 2600 miles on it. The So. California dealer got 3 in (I bought the last one) and they sold quick. I'm loving the FJR!!! Anxious to get the side cases.
