Standard piston ring set for the stock bore on the Honda XL600R, NX650 and XR650L. If youre 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.
Set comes with 4 rings and the oil ring spacer.
Be very careful when installing the cylinder over new rings, its 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.
