Complete cylinder head for the 50cc 139QMB / QMA engine. Unlike many cylinder heads offered, this one comes complete. This means valves, valve springs, valve stem seals, etc. are completely pre-assembled. The cylinder head is thus ready for installation and the fiddly replacement and grinding of the valves in conjunction with required special tools is eliminated.

The head is delivered without secondary air system [SLS]. This can be easily decommissioned, which benefits a höhen smoothness and a little more torque.

In the scope of delivery are not included rocker arm brücke and camshaft. Delivery is as shown.

  • short valves, because without SLS
  • .
  • Valve length: 64mm
