Stock carb jetted as follows:
Pilot 35, 3 turns out on the mixture screw. Tried a 40, idles better with the 35
Slide hole drilled with DJ kit provided drill bit, and I added the 09 DJ kit slide spring
DJ needle, clip 3rd groove from the top
Main jet DJ 124
Airbox lid on, snorkel removed.

Idles smooth, pulls hard to redline, no flat spots or stumbles. I have tried running without the airbox lid and richening up the needle and main. My bike seems to lose some low end pull and won't pull cleanly up to redline. Much better with airbox lid on.

drilled slide and the shorter spring? 1st time i've heard of that combo. interesting!

Spring

Ya don't have to cut the spring, I used bread-bag ties, after removing the plastic from the wire, compressed the first 4 - 5 coils wired them together then snipped the extra wire off
