Hi, i have done a few search's and can't fix the problem. I bought the bike, it is an 06 and has very low hours, the only thing done to the motor is a twin air filter and a full dr. d pipe and the o-ring mod. the jetting is a 168 main, 3rd clip on the needle and a 48 pilot with 2 turns out on the screw. i am at sea leval to 600 feet and it is about 35-45 degrees right now. It has a bad hesitation from an idle when you crack it realy fast, and when you hold a constent throttle crusing down the road at about 1/4 throttle it kind of miss's a little bit. what can i do to fix the problems? Thank you.
