I'm guessing I will need a sleeve and maybe a new piston at this point. any ideas on where I can find them??
definitely wasn't run lean.. everything else looks good. conrod looks like jewelry..
I do not think that is how it happened. I have done that before and it was because I took off the back plate on the motor with the piston on BDC (on the bottom of the stroke). Check your back plate and see if there is a groove cut in it for when the piston is at the bottom. If so then you probably pried it off with the piston on the bottom and broke the skirt off of the piston. Lessoned learned for me as now I make sure my piston is on the top EVERYTIME I removed the backplate on any motor.
