| I think you are running the full system? If so, then yes, there is a big hole in the fuelling between 4-5K rpm and if you hold the bike on a constant throttle in that range it feels awful. Apparently Ducati are aware of this and are releasing a new map in the not too distant future...... not date yet.
Mine does exactly the same.
As a side note, mine cut out completely on Sunday morning when I was crossing a dual carriageway! Fortunately it was early and there weren't any cars around and it stopped on the crossing on the central reservation. I had to push it back across to the side road and it took 4 or 5 goes with a bit of throttle to start. Ive also noticed a mysterious fuelling issue appearing at 7 and 9k rpm at full throttle in 5th and 6th gear. Perhaps my fuel pump is on the way out? |
