Rebuild your cylinder head the right way with one complete, matched kit. The Kibblewhite Cylinder Head Service Kit is designed to restore valve sealing, reduce wear, and bring back consistent engine performance after hours of hard riding. Instead of mixing parts from different sources, this kit bundles the key components needed for a proper top-end/cylinder head service.
It helps solve common problems like power loss, hard starting, low compression and premature valvetrain wear by replacing critical wear items—valves, guides, springs and seals—while also supplying a complete top-end gasket kit for clean, leak-free reassembly.
Key features:
✅ Complete cylinder head service bundle (valves, guides, springs, retainers, seals + top-end gasket kit)
✅ Black Diamond™ one-piece forged stainless valves engineered for improved wear properties and reduced friction
✅ C630 valve guides (copper/nickel/aluminum blend) plus Viton® valve stem seals for durability and stable sealing
Benefits of using it:
🔹 Saves time and avoids fitment guesswork—key parts are selected to work together as a system
🔹 Improves reliability under load with quality materials like titanium retainers and performance spring components
🔹 Great value for a proper top-end service by including the gasket kit and necessary small sealing parts
