It is already on this thread a few times, but Kientech makes a pilot screw for the DR200 that can be turned by hand, without a screwdriver. I have one on my XT225. Makes it easy to adjust with the engine running so you can get it just right without having to count turns, etc.
I won't spend more on a bike than I think it's worth, but if it's a good deal, I don't seem to have a problem buying bikes I don't need.
