More jetting questions...
I've searched through quite a few of the posts on this topic and I still have some questions. I've got a stock 02 KDX 220 (snorkel removed). Elevation is 500-1000ft. As far as the temp goes it's a wide range (Illinois) and I don't mind if I set it up for cooler weather (50-60 degrees)and then run a little rich when the temps climb. I'm currently running 32:1 semi-synthetic but I think I'll be changing to 40:1 with the same semi-synthetic (possibly full synthetic).
I haven't done the plug chop yet since neighbors are a little uptight about running it down the street at full throttle (and I'm close to the cop shop). I'm going to wait for the track to do that but I'd like to get in the ballpark before I head out.
I have the stock R1173L jet in the 3rd from top position, a 145 main and 42 pilot. From what I've seen and heard, most recommendations are to move the clip to the 2nd from top, run the stock main (145) and pilot (42) and then fine tune with the air screw.
Will that get me close? This is my first jetting experience and I'd hate for it to end badly (too lean).

I think that main would be much closer to a 155 ...not a 145. That would be quite lean for the 200. Pilot sounds close though. Needle 2nd from the top.
I live in Illinois too....

I was wrong... sorry! I don't have a clue on a 220 other than I would put a 35mm carb on it... or better yet...a RB modded one.

I've got a 220. I run in elevations pretty close to what you describe. I had a 142 main, 40 pilot (38 when it's hot in the summer), and stock needle on the 2nd clip, A/S at around 1.25 turns out with the 40 pilot and 0.75 to 1 with the 38. I assume you have the stock pipe, if you have a rev pipe, you'll have to richen the jetting. I also have the snorkel in but a bunch of holes drilled in the air box lid. I was running 32:1 at the time but now I mix at 40:1, always full synthetic.
Last winter I sent my carb and head to RB Designs. You should read up on this mod. I thought my bike ran pretty good set up as described above, but it really runs nice after the carb and head mod.
You should consider changing out the stock piston for a wiseco. The stocker has been known to fail. Search around, you'll find some info on this.
Have fun.

Marco, where in the 'Burbs do you live? I'm in Bartlett. Starved rock has riding 1.5hrs away, but I have yet to go there. I did go hiking there last weekend at the state park, and have to say that there is some crazy terrain (for IL) near the IL river...SANDY though. Will definitely have to go down south to ride w/ Inda/Crew, and I. Inda....Here's a silly question. Is Vandeberg going? Oh yeah, la like beer?

Thanks for the clarification. I haven't been to the State Park in years and thought maybe something had changed.
