Oh yeah, thought it might be helpful to post up the settings we have on both our 200s. They're '11s and I don't know what the differences compared to the '04 - probably the older style carb (Jake?).
On my EC200 I have the following:
40 pilot
R1470 Needle @#2
172 main
A/S 1.75 turns out
#7 slide
On my wife's EC200 we have:
42 pilot
NEDH #2 (needs more testing)
175 main
A/S 2.25 turns out
#6 slide
Our typical riding is probably similar to yours, though with less humidity. We ride in 1k - 4k feet with temps in the 60s this time of year.
Post up with what you find after you do more testing...I'll have more information today too
