Check for DTC's? If there is a problem then it should show up on the self-diagnostics. Off hand, I'd say it is probably just that the engine is cold and after you start it the first time, the injectors get enough gas in to start the second time around. Are you "goosing" the throttle like you would a carb bike while cranking? This will take it out of the warm up-enrichment table because the TPS is sending the ECM a "conflicting" message: when starting the EFI, leave the throttle alone. Are you waiting for the fuel pump to pressurize and the speedometer to make it's sweep (approx. 8 seconds after turning the key on) prior to hitting the start button? If "no" and "yes" to the above questions and no DTC's, next time you have it in for service, mention this problem: you may just be due for an upgrade (free) on the ECM.

I've had this problem also. I called Harley customer service and believe it or not they were aware of the problem. They gave me a reference number and told me to call back in about a month and they should have a fix. I haven't called them back yet because the problem seemed to work itself out. It will start then go to a really low idle then catch itself and idle at the correct rpm. It only happens on the initial startup in the mornings, the rest of the day, no problem.

Just got off the phone with customer service and they told me that they are still working on the solution. They said the fix will be a download with a new calibration. Should be available around spring time.
Sounds good to me I guess.

My 09 has done this since Sept when I bought it. My dealer however has been trying to solve the issue by downloading another map into the ECM, changing the ECM with another one,also sending the ECM back to the factory for a new download, and last replaced the engine temp sensor in the front head just last week. It use to die 2-3 times per week however has only died once the past month even after all these changes. Seems like sitting overnite in warmer weather causes it more. Dealer also says the factory is working on another download. Also has had the fuel pressures checked and ok. Hope a cure comes soon.
