Add fuel? or lower IAC?

Here's my problem.

When I hit the starter on the bike (now that it's colder)... The IAC starts at a high value. The bike will run for a second, then die. Hit the starter the second time... same. Third time, and the bike will remain running and warm up correctly. Watching the Live View, I can see where the IAC value starts high, and on each subsequent start it is a lower value, and the third push of the button, the value drops enough that the bike continues running.

On a whim, I lowered the ET based IAC Position Table for that temperature rang just a little. This morning (same outside and ET as yesterday) I hooked up the computer, and started the bike. The initial value was lower than it was yesterday (understandably), and the bike only required two pushes of the starter.

Should I lower the value just a little more until the value converges quick enough to continue running? Or should I be adding fuel somewhere?

Once the IAC drops the AFR shows good values all the way up to warm-up (actually, it's still a tad rich at idle at 1000 RPM)

Here's a log from this morning. You can see where the first push of the button, the bike leaned out and died, then the second push it continued to run.

I threw in my map too.
