Spun bearing? Replace pitted pistons?
#22
Holy ****, looks like #3 con rod was about to detonate. In the assembled shot, you can see #3 piston sitting low.
On the plus side, I don't see any indication of detonation. I guess I was seeing carbon buildup w/ the boreoscope, not pitting after all.
A buddy of mine (who builds bike motors) told me to run it and track down the noise w/ a stethescope, good thing I didn't

They look ok to me, but what do I know.
Interesting finds:
-Crazy runout on the thrust bearing
-Flange on the crank timing gear is missing a chunk (probably unrelated)
-Pistons and rings look good, no damage that I can see
I'm seriously considering getting a pro to build the bottom end, this isn't the area where I want to learn by mistakes.
In order, cylinders 1 - 4:
