I am restoring a 74 sl125. I am having trouble identyfing the piston size. The piston is broken at the skirt so need to replace. The bore measures 56.5 mm, the original piston measures 55.96 is this one over size or 2 oversize? The Piston is marked with ´Honda´ and a B, the rings are marked 50. Any help would be appreciated. Thanks
