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 also requires special tools, is not necessary.
The head comes with secondary air system (SAS).
