Since i bought it new it has a weird off idle bog, Cant figure it out. I bought some K@N filters for it and removed the air box and rejetted it to the Dyna Jet specs for what i was doing. Have a 280 jet and whatever needles it came with on the middle clip and 2.5 turns out on the air screw. Still has the off idle bog but after the bog it goes fine. Im stumped!!!
