I thought it was only the rods that were bad but after having to drive the crankshaft out found melted cylinder bearing surface. The rods were messed up too. Actually #2 rod cap was loose.

Honda doesn't offer a bushing to repair the damage so I hoping a light reaming will stay within specs. Will not clean it like new but better than it is now. Just don't want to take too much material out. Adjustable hand reamers are not the easiest to use. They tend to chatter and hang.

Usually I just see rod journals screwed up but in this Honda the magneto side bearing is the worst with light aluminum on #2 rod journal. The acid took of all of the aluminum transfers
