Im pretty sure they're all 5mm I just solder and redrill mine to tune them, never replaced a jet, no sense in buying jets when its so easy just to solder and redrill them and get a fine tune on them that way, if it doesnt 4 stroke at cruise speed then you probably have an ok tune on it but if it does then you'll notice a performance increase by decreasing main jet size.
