Lost #3 cylinder, 1 and 2 have 125lbs of compression. Gonna bore #3, need to know if I HAVE TO bore #1 and #2? only going .010 over, because cylinder is not that bad.

Nathan.... Bore only if the cylinder(s) are damaged in any manner (scored, scuffed, etc). Otherwise, simply hone them to obtain a crisscross pattern and eliminate the glaze in order for the new piston rings to seat properly.
