I'm sure this question has been asked but I couldn't find anything on TT that specifically talks about a jerky throttle response off idle and at slow speeds for the '09. Normally I use the bike for the track where I have NO issues. But I just came back from 3 days at Durhamtown where I rode a lot of single track. In that environment, I noticed that it was very difficult to maintain a flow at slow speeds because the slightest change in throttle possition caused the bike to jerk forward (like it over reacts to small throttle openings). I also noticed that its very difficult to maintain a steady speed with small throttle openings. I've had several other brands of 450's prior to 2009 and never experienced this problem. Anyone have a fix?
