Default M8 Cold start issue

I've got a 2022 Road King with 150 miles so far on the 107 M8. I find it awkward to start when it's cold. (Sitting all night at 30-40 degrees).

When I press the starter button, it fires right up, runs a few seconds then stalls. I have to give it some throttle to keep it running. After about 4 - 5 seconds, I can let go of the throttle and it idles the way it should. After the engine has warmed up, it starts up and runs normally. -- (FWIW.. I'm starting with the transmission in neutral)

Is this normal behavior or should I head down to the dealership to have them do some tweaking?

I'd have the dealer look at it....

Are you waiting for the fuel pump to prime?

When you start it do you take it out and ride it, or shut it down then start it again a few days later, then repeat etc?

The pump is fully primed when I start it. I give it a couple of seconds after the speedo sweeps to the right and returns to zero. Normally I start it up and head out. That's what I did yesterday. But I have just started it on occasion only to hear it run. (It's a new toy after all ).
