🔥 YFZ450 '04-13 / YZ450F '03-05 / WR450F '03-06 White Diamond Valve Kit + Big Bore Head Gasket + KPMI RED Seals 🔥

🛠️ Product Overview

Refresh your Yamaha 450-cc engine with Kibblewhite White Diamond™ stainless-steel intake, center-intake, and exhaust valves teamed with legendary KPMI® RED Viton® stem seals. EV8 one-piece stainless valves shed weight yet out-last OEM titanium, while the high-temp RED seals deliver leak-free reliability no matter how hard you ride.

✅ What’s Inside

  • Complete 5-Valve Set – 2 outer intake, 1 center intake, 2 exhaust
  • KPMI RED Viton Valve-Stem Seals – 5 pcs, extreme-heat rated
  • Cometic Big Bore 98mm MLS Head Gasket – big bore friendly sealing
  • Direct OEM Replacement – swaps straight in for Yamaha OEM
  • All items brand-new, backed by KPMI & BPRATV warranty
Advantage What It Means for You
EV8 Stainless 1-Piece Valves Stronger & longer-lasting than OEM titanium at high RPM
360° Hard-Chrome Finish Reduces stem friction for stable lash & smoother revs
RED Viton Seals Stay pliable in extreme heat; stop oil blow-by
Improved Airflow Lighter tulip profile boosts CFM → more HP & torque
Drop-In Fitment No machining—bolt in, set lash, ride
