After the 2nd gear recall on my 2019 ES, I could tell it was not the same bike. After talking to the dealer who did the work, I realized there was no way to undo the ECU reflash. I found a used ECU from a low mileage 2016 FJR and replaced it for the reflashed one. Lo and behold, my old friend came back to life. I am as happy as a newly elected DC politician. Set for life.... PS. It looks as though Yamaha has updated the new ECU's with a new part number. My Yamaha dealer tells me that the new ECU has probably been updated to comply with the 2nd gear reflash recall. HTH
