It's not an R issue. It's a Panigale issue that's been discussed over and over for the last 18 months.
-- not for nothing here.....it is way older than 18mos - i had this issue starting on my 955 (1995) and a 996(2000).....not to forget a 999 (2004?) as well....the nature of the twin engine (huge pistons) and fueling has been with Ducati for quite a while
