I had the dealer load the latest FI map when I had the bike in for the 500 mile service and that helped a little. Also adjusting out most of the freeplay helped, too. What really got it to where I'm ok with it, especially off-road, was putting a rubber O-ring between the end of the throttle grip and the metal bar-end that the handgaurds mount to. Adds enough friction to take all the abrupt out of the system...you have to consciously move the throttle. Works for me, may or may not for you. I'm used to the feel of it because I've done it to my BMW RT, which I did as more of a cruise control than to solve throttle problems. Don't really need to on the DRZ, it's pretty smooth as is. YMMV. Cheers!
