Product Details

The Cometic C3148-EST is a complete top end gasket kit designed for Yamaha engines with a 98mm bore. This comprehensive kit features Cometic's Extreme Sealing Technology (EST), which combines embossed stainless steel construction with a proprietary rubber coating for superior sealing performance.

Extreme Sealing Technology Benefits:

  • Embossed stainless steel head, base, and rocker gaskets with proprietary rubber material coating
  • Advanced heat dissipation draws heat away from the combustion ring and distributes it evenly across the gasket surface
  • Eliminates hot spots that can lead to premature gasket failure
  • Superior sealing under extreme temperatures and pressures

Complete Top End Rebuild Kit:

  • Includes all necessary gaskets, seals, and O-rings for complete top end rebuild
  • Covers everything from the cylinder base upward
  • 98mm bore specification ensures proper fitment for compatible Yamaha engines
  • Professional-grade components for reliable, long-lasting performance

Cometic gaskets are engineered for performance applications and provide the durability and sealing integrity required for high-performance and stock rebuilds alike.
