Product Details

The Cometic C7905-EST Extreme Sealing Technology (EST) Top End Gasket Kit is engineered specifically for 77mm bore Yamaha engines. This comprehensive kit provides everything needed for a complete top-end rebuild with advanced sealing performance.

Extreme Sealing Technology Features:

  • Embossed stainless steel head, base, and rocker gaskets with proprietary rubber coating for superior sealing
  • Advanced heat dissipation design draws heat away from the combustion ring and distributes it evenly across the gasket surface
  • Eliminates hot spots and prevents premature gasket failure
  • Complete gasket set includes all necessary gaskets, seals, and O-rings for cylinder base upward rebuild

Cometic's EST technology combines the strength of stainless steel with the conformability of rubber-coated surfaces, ensuring reliable sealing even under extreme operating conditions. This kit is designed for 77mm bore applications and includes all components required for a professional top-end rebuild.

Wow, super fast shipping and the best prices!

great fast shipping best price even with high shipping fees

The fact that I could use my Amazon credentials made the purchase quick and easy.

The price as well as the turn time for receiving my product was great. I placed an order late Sunday evening and I have received my order by Wednesday of that week. I still can't get over how great the price was for the bike rack I ordered compared to all of the other sites out there.

Great product at a very reasonable price. Driver could have helped lower package.

Easy checkout, great price

first time, will be back

good so far

All good so far. Could be a little clearer about if the order will include needed any additionally needed hardware for install.

They had two items that I wanted in stock with the lowest price I've seen online anywhere, and had super affordable shipping options.
