DetailsComplete cylinder head for the 50cc 139QMB/QMA engine. Different from many other cylinder heads on the market, this one comes complete, i.e. valves, valve springs, valve stem seals etc. are completely pre-assembled. This way, the cylinder head is ready to be installed and the pesky replacing and grinding-in of the valves, which would also require special tools, is not necessary.
The head comes without secondary air system (SAS), which can simply be blinded off. This results in smoother running and a bit more torque.
