Product Details

The Cometic C3147-EST Top End Gasket Kit is engineered with Extreme Sealing Technology (EST) for superior performance in demanding powersports applications. Designed for Yamaha engines with a 96mm bore, this comprehensive kit provides everything needed for a complete top end rebuild.

Extreme Sealing Technology (EST):

  • Embossed stainless steel head, base, and rocker gaskets with proprietary rubber coating
  • Advanced material design draws heat away from the combustion ring
  • Even heat dissipation across gasket surface eliminates hot spots and prevents gasket failure
  • Superior sealing performance under extreme temperatures and pressures

Complete Kit Includes:

  • All necessary gaskets for cylinder head, base, and rocker assemblies
  • Required seals and O-rings for complete top end rebuild
  • Everything needed to rebuild from cylinder base upward

Cometic gaskets are precision-manufactured to exact specifications, ensuring reliable sealing and long-lasting performance. This kit is ideal for routine maintenance, performance builds, or engine rebuilds on compatible Yamaha engines.

you guys always beat summit, some sort of shipping discount on larger orders would be nice though. Maybe an amazon prime type thing.

Easy transaction

Fast shipping, exactly what I was looking for, at the best price I could find! Thanks!!

Ordered a Thule hitch and was a little skeptical because I hadn't heard of this company. I was pleasantly surprised by the quickness of response when I ordered, I received an email immediately, and the order arrived just 2 days after it was ordered. This company goes to the top of my list.

Great price, fast shipping
