Intake Manifold for CSC Go, Bella Classic, Nitro Sport, and Pug Scooters
This intake manifold is built to take the place of the factory piece on several CSC models, among them the go, go MAX, Bella Classic, Nitro Sport, and Pug scooters. It is made for 139QMB engines, so it lines up correctly and works as intended. Keeping your scooter running well matters, and this part is one way to support that. It is among the dependable GY6 50cc scooter parts worth looking at for a repair or an upgrade.
Functionality and Compatibility
The intake manifold delivers the air-fuel mixture to the engine. It works with a range of 50cc and 80cc engines that use 139QMB-style engine codes. If your engine code contains "QM" or "FM," this manifold should be a match for your scooter.
Installation Details
The part includes a vacuum port, which the engine needs to run properly. On the engine mount side the inner diameter is 17mm, and on the carb mount side it is 26mm. Bolt holes are spaced 45mm apart, giving a firm seat once installed. The piece is meant to go in directly where the original manifold sits.
