MBK 51 AIR DAKOTA (ref: 192246)

The DOPPLER cylinder head is made of aluminium. The combustion chamber is machined with a bi-hemispherical switch effect, providing better engine compression. The central spark plug offers better explosion and better thrust on the piston. The O-ring gasket mounting provides better watertightness and a more accurate chamber volume. This cylinder head does not come with a decompressor to limitate losses and leaks.
