+1! Just be sure to turn the handlebar lock to lock while feeling for free play. If there's any tug on throttle cable, you may end up with Toyota.. aka unintended acceleration.One action you can take that will not eradicate the abruptness at low throttle settings, but will help you to overcome it. That is to take as much slack/freeplay out of the throttle cables as possible without affecting tickover. My Tech did that with my 1000DL and it helped.
Brakes can also be used to smooth throttle tip in. I'm so used to trail braking and getting on the throttle as I'm easily off the brake(s) that twitching is never an issue really. In a straight line (say in slow town traffic), light application of rear brake can be used before applying throttle and then easily off the brake. Once this becomes habit, you can make any bike feel incredibly smooth. Of course there's nothing wrong with clutch feathering too.I think it's just nature of the bike, fuel mapping. At slow speeds the throttle is like a light switch, either on or off, so you're either accelerating or decelerating, very difficult to maintain a steady speed. It helps to ride in a higher gear and sometimes I find myself working the clutch to smooth it out. As others have mentioned too much throttle play makes it worse.
