I would love to fix the "lag" while rolling on the throttle after closed throttle decel. No matter how smoothly I try to twist the throttle, it feels like there is a good 1/2 second where its not applying fuel, then a surge of power, and then it calms down. My 04 never had this issue. I have ridden alot of bikes as well, and this is the worst I have ever felt a throttle be. Maybe my Scorpion pipes with no tune is causing the problem. It can be very unsettling though dipping into a corner and getting a surge of power as if you blipped the throttle.
