Yup, that's what I do.
Full choke to start, run for a minute, back to half way, ride off, fully in after a few hundred yards and goose until happy.

^^^That's similar to my start procedure. Full choke and idle for a minute on start up. Half choke and ride away. Choke-in after a mile and keep the throttle goosed at stops until warmed up.

What bothers me is that I had an '05 Bonnie in my possession for a few days that started with choke out and then you could just bang it in after 10 seconds and the bike was fine to ride away. It didn't stumble on acceleration when not warmed up.

Fact of the matter is, no two bikes are the same. That's what really kind of makes it challenging to tune these bikes. You can have two of the same bikes sitting side by side with the same mods but require different settings of jets and air mixture screws. It would be nice to be able to jet the bike the same as a buddy and expect to achieve the same results. Unfortunately, that isn't going to happen.

Points taken. I'll be resizing the mains soon along with the pilots. I think, first an oil change and a dyno run is in order to get a good baseline.

Try 3 turns out on the mixtures before splashing out on bigger pilots, it might be all it needs. Remember, open silencers tend to pop a bit at the best of times.

You should try an EFI bike. Mine idles at about 1,000 rpm from the time that I start it. No stumbles or stalls. Runs perfect cold or warm.
