It will never start when cold.
It will never start when hot if its in gear
it only starts when hot if I kill it and immediately restart and in neutral. If I kill it and wait a couple minutes it wont start. if I kill it in gear and try to restart immediately it wont start.
It also wont start on the first kick anymore, now it takes 2 or sometimes 3 kicks. When I first got the bike it would start on the first kick. This is not a big deal but wondering if this could be related in any way.

This is really bumming me out. The bike is amazing everywhere else but this starter is getting frustrating. I was told by a rep and a dealer before I bought the bike that it would be fine with the new CDI and cables, but it seems the problem goes way beyond that. its too bad GasGas wont do more about the issue other than reflashing the CDI and giving you one cable then leaving the rest up to you. Ive been very vocal about how great this bike is but its getting hard when realizing how in depth the starter issue is.

I'm concerned that you're looking at 2 separate issues when I make assumptions about what you're trying to describe with the terms you're using.

I was very frustrated when I got my bike and tackled the same issues you're apparently dealing with. It sucks, I'm sorry it's such a hassle on the 18s.

You make several won't start statements in the post I quoted. Are some of them won't crank vs won't start?

When you mention that it's now harder to start even when kicking it makes me wonder if the temps you were riding in previously have changed and the jetting is close enough to be effected by it.

I believe that you are possibly employing far too much faith in the "210cca" and Shoria battery in general. You can help yourself a lot by metering your issues.

A couple quick videos show the difference between an advertised 220cca battery that was acting the same as the OEM unit (the oem unit starts a 2017 KTM 300 just dandy with no issues FWIW)
You can see that the batteries began with the same charge but did absolutely not act the same once they reached coup d foute and began recovering.

Video 2 was same day, same circumstances, cold bike that video 1 was. Drastically different results.
