That's not wear in the cylinders. That's where that block sat up with water in it and it rusted. Looks like somebody did run a hone through it though. That was nice of um. Dang man. Sure am sorry.
The hone was from when it was rebuilt in 2012ish. I rebuilt the motor back then. It has less then 250 miles on it. What gets me is where the water came from. Makes no sense to me.
