Unless I'm mistaken (it happens often), mchad was having issues prior to the tuner. This is becoming a rather widespread problem based on the number of threads and responses from others reporting the same/similar issue.
Tuning an engine to run cooler and smoother with reduced cranking pressures should not ever result in a no-start. I believe there is a systematic problem at the OEM level. Maybe a batch of bad starters or some overlooked failure mode of components unique to the 110... Dunno, but there is a problem.

OP-
When is your bike going to the dealer to see if they resolve this issue? Curious what they say-

The problem may simply be that HD puts in the same starters and battery size that they used on their 88" bikes years ago. Now, at 110" and with some bikes adding additional motor work, when new, they are fine, but as battery strength and starter strength erodes, over time, especially under hot restart load, they struggle...

Spring update - SUCCESS!
Now that the snow and salt are gone for the season, I've been getting a lot of miles in, and I'm happy to say I have not been able to recreate the hard start problem at all. I think the thing that I missed was the starting timing retard on the new FuelMoto tune. Once I did that, its been firing right up. I mean RIGHT UP. One turn and it's running. Even at the dreaded heat soaked gas fill up stops...
So since it was happening even with the new battery and heavier gauge cables, the tune mod was the clincher I would have to say. It's got to be at least 30 or so starts since I flashed it, w/o any hard starts or funky noises.
So for anyone else, look at my post #45 on page 5 of this thread. This was the fix for me...
I know I should just keep my damn mouth shut, as it'll probably grind and bang when I go out to start up for my ride home from work later... Just watch.

Besides, the retarding of the timing i did was much greater then what was on the stock tune, which if you've read other posts you've have seen that others have the same or similar starting problem with stock bikes. So maybe HD should apologize to us for making us do their work for them?
But I will apologize to you, for what I'm thinking about calling you, Mr. helpful.
Have a nice day

Well, I said I would get back after I had put some time on my new Baker Comp Sprocket and how I feel it helped with what I think is just one of the culprits that lead to these starting issues. For awhile HD didn't upgrade the comp sprocket when they went from the 88" to the 96", but did when they went to the 103" and 110". Although the SE version is considered an upgrade, it is still the same basic design and uses the same style compression springs that over time loose their spring pressure, if they maintain it at all, thus not pushing enough pressure back on the compensator ramps causing the kick back. I swapped over to the Baker Comp Sprocket, which required the addition of the SE stator rotor (like the ones on the 103" and 110", they don't have the built on spring pocket). I have had zero starting issue as of yet after this change. Again, IMO, it's just one of the many possible issues that cause this problem.
88" and 96" Comp with built in spring pack.
The SE Rotor the newer 103" and 110" use
and the newer spring pack it uses
