I believe this to have been a brand new chain, it doesn’t look to have been touched. The rakers haven’t been touched either. I was into some maple today that was 30+”
This was on my 385 with 28” Total bar. It was chattering so badly I figured something was wrong with it and I ended up grabbing a 390 to do what I was doing and went back to this to look into it after. I took the clutch apart and checked the bearing, also the tip roller and the bar grooves all seemed fine, to me it looks like it needs more hook, I can grind it, or file it and experiment, but for purposes of ruling out, I put a different chain on that I had taken off for sharpening and while it needed a file, it cleared up the chatter.
