Used KYMCO scooter 50cc 4T INLET PIPE ASSY / INTAKE MANIFOLD - part # 1711A-LBC9-900.  Good condition.  Pretty sure this part fits ALL the KYMCO 50cc 4T (4-stroke) engines, regardless of scooter model.  This particular one came off an 1,800-mile KYMCO Sento 50, but should also fit the Agility 50, Super 8 50 4T, Vitality 50 4T and People S 50 scooter models.
