I had a similar problem with mine except it was a cold-start problem and shimming the injectors worked. At the same time, i did have a battery issue too. I took the batteries to O'Reillys twice to have them checked out and they said they tested fine even though they would not turn the truck over but 1 revolution. Long story short, I replaced the batteries with AGM batteries from the same place and the truck turned over fine.

I have had experiences with large inch/high compression V-twin bikes not engaging the starter due to low amperage in the battery even though it measured 12 volts.

The 2 things I would look at are your starter solenoid and batteries, regardless if they are new or not. If a solenoid is out, you wont hear the starter gear engaging the flywheel. If it is batteries, the starter gear might engage but not have the amperage to turn the truck over.

Jump the starter out and check the voltage drop - that should give you a clue. Post a video

So the starter engages but doesn't turn the flywheel? Or it just clicks? Either it is hydro locked or you dont have enough amperage to spin it over.
