Undersize crank/rod bearing

Nothing wrong with an undersize crank at all !! That's what the bearings are for,to make up the difference !! Only thing that I would do is pull it apart and redo the break in lube on the bearings just to be on the safe side.Couldn't hurt to put a little Marvel Mystery oil in the cylinders either ! But I'm sure there are far smarter than I that will speak up !!:walk:
