So when I start up my bike from cold on a warm day, and I blip the throttle, she'll die. If I choke it a bit, I can rev through the whole range. Once the engine warms up a tiny bit, i don't need the choke to get to redline, but my idle is week and I have to hold the throttle open a bit at stops. When it gets a bit warmer, it idles perfectly at 1500 and is a monster on the accel. Any ideas? 22.5 pilot, 65 mid mains, 145 mains, v&h exhaust, k&n lunchbox, adjustable needles set to 1 position away from point, 2.5 turns on air screw. Advice?

Carbs are not as efficient when cold. They don't atomize the fuel as well when cold. Less atomization = more fuel consumption and less efficiency. Hence the reason for a choke. I'd say it's perfectly fine if it runs well fully warmed up.
