Although not perfect for a new bike, my solution was changing the carb to the Mikuni jetting it for sea level.

Power seems to be up, starts and idles on first try with very short starter spin time, idles on full choke when very cold . Much different bike. Best mod I've made so far.
My results were about the same I would have to give it gas to get it started and would sometimes have to hold the throttle. I would also have to adjust the idle screw up high then turn it down as the bike warmed. When I changed to the mikuni I set the idle screw once and haven't changed it since I just have to decide on choke position depending on temperature. On a side note first gear is extremely short with stock gearing maybe 10 mph tops.
