Cylinder head 101 OCTANE GY6 139QMB with SLS valves, L=64mm

Complete cylinder head for the 50cc 139QMB / QMA engine. In contrast to many cylinder heads on offer, this one is supplied complete. This means that valves, valve springs, valve stem seals etc. are completely pre-assembled. The cylinder head is therefore ready for installation and the fiddly replacement and grinding in of the valves in conjunction with the required special tools is no longer necessary.
The head is supplied with a connection for the secondary air system [SLS].
The rocker arm bracket and camshaft are not included in the scope of delivery. Delivery is as shown.
