Set of 4 Standard piston ring sets for the stock bore on the Honda CB900 from 80-82. If you're just freshening up your top end and having the cylinders honed, install a fresh set of rings to ensure a tight fit. Make sure to stagger the ring gaps according to the manual.
Each set comes with 4 rings and the oil ring spacer as shown in the photo.
Be very careful when installing the cylinder over new rings, it's helpful to have the proper tool to keep the rings compressed as you lower the cylinder over the pistons. Try to use only plastic tipped tools to prevent from scratching aluminum surfaces.
