CORRECTION: piston "EX" smaller valve indent should be facing down toward the exhaust. This means the entire piston engrave 61mm and the Taida Star symbol would be upside-down NOT like the video shown. We did this for the reading aesthetic of what piston size/brand installed. *New designed, now come aesthetically upright Taida Star symbol and it's marked "IN" piston near indent should face up (intake).
