RE: Break-in a rebuilt engine?
You don't need to hone the sleeve. You'll most likely just ruin it if you even try.
You should knock the glaze off the cylinder. Easy to do with a scotch brite pad and some toothpaste. Just spend about 5 minutes LIGHTLY rubbing the cylinder with toothpaste and the pad. A couple tiny drops of water in the paste will help to thin it down a bit. Rinse well in warm water and re-assemble with lube.
Don't get in there and rub the heck out of it. You'll scratch the cylinder. Thats a BIG NO-NO. Just run the pad in there and lightly work the paste around.
You really won't see much material come off the cylinder. The paste will just turn a little brown.
