I have a 2007 919 also. Love the bike. I ride shorter ( 50-150 miles ) rides up in the mountains. Lots of windies .... I changed my oil at 500 ( GN4 ) and then at 2000 to Honda Full synthetic (4 stroke oil ) I don't have a lot of time to ride. Here and there. I put maybe 1500-2000 a year on this...
