cylinder head cover w/o secondary air system SAS / valve cover -101 OCTANE- for GY6 50cc 139QMB/QMA

Original valve cover suitable for Chinese 4-stroke engines GY6 139QMB/QMA. The cover is supplied without SLS connection [secondary air system]. Thus it can be used in case of defects on the original part or to shut down the secondary air system. The engine thus gains a little more smoothness and a little more power.

For installation, only the connection for the crankcase ventilation [hose with the small angle connection] must be taken over from the old cover.

The valve cover gasket is not included in the scope of delivery. We recommend that you generally replace it after removing the valve cover._{AI-translation}
