I'm wondering if this is normal. Before jetting, to start the bike, I would choke it and hit the button. The engine would immediately fire and run strong, quickly racing up to 2500-3000 rpm until I esed off the choke. Then there was a fairly long warm up period, and the bike would stumble and cough til she warmed up all the way.
After jetting (and Cobra f1-R slip-on) I start her the same way but do NOT get that immediate explosion, and racing engine...it starts, but lopes along at about 1000-1100 rpm and after about 10-15 sec. runs better when I cut the choke. However, I now have NO stumbling or hesitation even with a very short warm up. Idle after warm-up is around 1300-1500.
Is this new starting pattern a normal result of jetting?
It might be a little rich. Try going in on the screws a little.
I managed to over richen my Virago. It starts only with 1/2 to 3/4 choke. Full choke and it sorta sputters. I'd try 1/2 choke basically. Also what jeff said. And dont take off the choke in 15 seconds even if the bike will hold idle. This is a case of too much of a good thing. If the bike warms up in 3-5 mins its too long. If the bike warms up in 15 seconds that's too short. Get it to where it will run stable at 1 min or so...the engine needs that little bit of heat and that time will get it to where its lubed right.
Cool.

Thanks for the advice, guys...I'll play with the bike tomorrow when I'm off. :cheers:
