Fwiw... ktm made the 1190 a dog under 3500 rpm to deal with carb. Above that was better and the real fun began somewhere north of 6k. A company called rottweiler came up with a kit to richen things up at lower rpm. Huge benefits. Is the 390 suffering from low end starvation? Does anyone have a work around? Just curious...
