RTC, you and I have almost identical setups-
'06 2/3 spacer, 52.5 pilot w/ bleed holes, 150 main, dyna power pipe (pretty open), K&N drop in filter, 2 1/4 turns on the air mix.
My bike runs absolutely GREAT! Choke her out just to get it running and then immediately push the choke back in. Ready to ride after about 30-40 seconds of warmup...no surging, pulls great in the lower gears, plenty fast on the high end (maybe 85...then I chicken out).
I put a raptor petcock in cuz it was having cold weather symptoms (stumbling, would die at lights) and haven't had a lick of trouble since.
I think I pretty much got her where I want her.
P.S. elevation- 5280ft
