I own a 2007 suzuki gsxr 600, in between 4000-6000 RPM there is no real throttle control, your can not accelerate or decelerate smoothly, its real jerky, if this happens in a corner the back tire could be thrown into a skid causing a wreck, the problem does not exist all the time, and I have found when you find the problem happening if you will pull over and restart the bike the problem will go away for awhile.

On/off throttle causes sudden acceleration and deceleration. Bike would jerk when the throttle is slightly turn on and then off.
Abrupt throttle response. Bike seems to turn on/off quickly when trying to maintain speed. Happens at least once a ride(hour or so rides). Suzuki dealerships don't know what the problem is. Other people with the same bike have this problem as well.
