Default Compensator or Battery Problem?

I have a 2010 EG Classic. It had a bad Comp from the factory with the classic bang on some startups. At 6,000 Miles I replaced it with the SE version. All was fine until at 16,000 miles the bang came back. I took it to the dealer and the mechanic said he put a shim in and all was fine again. now at 27,000 the bang is back when the bike is restarted hot.
Also my battery is 4 yrs, 1 month old and I have been noticing a short hesitation at startup for a few months BUT if I put the battery on the charger for a day or so and then remove it the startup is instantaneous.
Tonight I took the charger off, the bike started up with gusto. I went for a short ride to heat it up, came home, shut the bike off, waited about 5 minutes, started it up and heard the compensator bang.
pulled it in the garage, put the charger on the battery, the bike started perfectly, no bang.
Is it possible a weak battery can cause the compensator to bang or do you think it's time for another compensator?

Being a 4 year old battery I would start with that first.... good insurance regardless. Then go from there.

The Harley mechanic did put a shim in it at 16,000 miles, so he told me. And they charged me for it too!! Whatever he did worked until now at 27,000 miles.

A weak battery can allow the starter to back torque. So, go after the battery first.

Of course they charge you. Seems like he gave you a 11,000 mile answer!

Had similar symptoms on my 16. When really hot it was normal for it to not start at all. Let it sit and cool down a bit and it would fire right up. Battery was older too, didn't do great on load test but good enough. Removed the comp and went with a solid sprocket, zero issues since then and fires up every time.

Had the same issue and it was the stock clutch. I replaced it with the Alto Carbonite and all starting issues went away. Just my thoughts.....
