Important Fitment Information
Fitment on Chinese scooters is best confirmed by engine and model code rather than registration year. Compare the 19 mm inlet, 28 mm manifold-side outside diameter, 39 mm filter-side outside diameter, mounting arrangement, throttle-cable connection, choke type/connector, fuel and vacuum connections and jetting with the carburettor currently fitted before ordering.
Do not order solely by engine capacity or body style. Some visually similar scooters use different carburettors even when the model name is similar.
