It was so long ago that I had the motor built. I vaguely remember having to bore larger, due to cylinder wall pitting. I think I originally had .050 over pistons, and had to go to .080. I also can't remember if we sleeved, or just talked about it as an option. Either way, this sucks. Still trying to get ahold of builder, and trying to figure out what we did. This is what I get for dragging my feet.
