2010 limited. love the bike and only has 2500 miles on it. no mods yet. when i am cruising in any gear at 2800 rpm, all feels smooth as silk. at 3000 it is very consistent that i start to feel a clunky kind of vibration through my floorboards into my feet. it is very distinguished and consistent. smooths out again after 32-3300 rpm. i can feel it at 2800 if i start to go to WPT or of i am accelerating up a hill. could it have something to do with fuel management or does it sound mechanical.

thanks.
