K I am getting ready to put this thing back together and I wanna be sure I am good to go. I had no knock previously but when I shake the rod I get Maybe 1mm or 2 of side to side movement, very slight feels solid, no bearing noises. I am gonna flush the case the desil tonight to get all the cruddies out... Dose the piston rod thing seem usual?

All roller bearing cranks are going to have a little side to side movement at the big end. It's up and down slop that causes a knock. My Clymers manual gives a spec of 0.10 to 0.65 mm
with a wear limit of 1.0 mm, but you have to actually measure it, not just wiggle it back and forth and estimate.

My best guess is that you are fine, though.
