More teardown. Here I start into the engine part of the build. Took about 30 minutes to break down.

Everything looks really clean inside. I am impressed with how well it has taken the desert dust.
2 Years ago when I rebuilt, due to a cracked piston skirt, I took some measurements.
03/05/2011
Big end bearing play 0.000" (Min/Max 0.000"/0.009")
Piston ring end gap 0.012" and 0.014" (Min/Max 0.010"/0.024")
New measurements taken
01/29/2013
Big end bearing play 0.004" (Min/Max 0.000"/0.009")
Piston ring end gap 0.027" and 0.032" (Min/Max 0.010"/0.024")
So, over time I have reached max wear on the rings. Time for new.
And the big end bearing is "moving" over time, so it's time to change it.
Piston looks new with a little soot built on the crown. Perfectly new demensions, and cylinder/piston clearance is still new spec.
Piston pin looks burned, I'll swap it, along with a new pin bearing of course. New clips to boot.

Cylinder looks great, I'll hit it with a hone prior to installing new rings.
