IMPORTANT NOTE: Again this piston fits 70cc and 90cc engines---both size of engines have the same bore size. BUT different stroke lengths on the crankshaft. You can not put a 90cc CYLINDER JUG on a 70cc engine---Jug is longer and you will have no compression. Vice Versa means piston will hit the head and cause engine damage. Keep this in mind when ordering cylinder kits or cylinder jugs.
Kit ships with rings, piston, pin and clips.
