This has happened about 3-4 times on my 2020 r1250 - usually after it’s sat in the garage for 3-4 weeks . Starts as usual first touch of the button but couple of seconds after it stutters but clears if you give it a quick blip - nothing for me to be concerned about but happening enough for it to be getting my attention , always using super unleaded and bike is stored in a dry garage / covered up . Has anyone had this - lastly only ever hand wash my bike - bike has now covered 9500 miles
