Valve White Diamond® KIBBLEWHITE (Manufacturer Ref: 40-40143H): machined exhaust valve for cross competition. Designed for demanding cylinder heads, this monobloc valve ensures precise industrial manufacturing through CNC machining from forged stainless steel EV8 or Inconel-751 components. Each piece receives a 360º anode electroplating for a uniform high-quality hard chrome coating.
Intended for cross engines where seat quality, guidance, and dimensional stability are crucial, the White Diamond® fits on cylinder heads requiring a 25 mm exhaust valve. Note: installation requires the use of the Kibblewhite spring kit (sold separately) to ensure proper operation and adequate valve clearance.
Common compatibilities: Kawasaki KX 250 F (KX250X - 2010, KX250Y - 2012, KX250Z - 2016). Always check your model references before ordering.
