  • Increasing the OEM's design of 47mm diameter by 2mm, 49mm, allows for a tighter degree of flow through the cylinder.
  • Weight slightly increased over OEM's; suitable for HIGHER RPM's
  • The nitrated shaft optimizes operation, an iron-clad solution against pitting.
  • Polished valve plate "swirl-polished" allows for optimum flow characteristics; precisely milled 45° angle valve seat.
  • In combination with other tuning measures (e.g. flow-bench, carb tuning, performance cams etc.) this performance valve is a significant performance improvement.
