Cometic Top End Gasket Kit - Suzuki RMZ250 2010-2026

MLS stands for Multi-Layer Steel. It refers to the construction of the head gasket, which is made from multiple layers of steel to provide superior strength, sealing, and resistance to deformation under high pressure and temperature.

EST uses a proprietary rubber coating on embossed stainless steel layers. This design helps to effectively draw heat away from the combustion ring and dissipate it evenly, preventing hot spots that can lead to gasket failure and improving overall sealing performance.

Typically, MLS gaskets with EST coatings do not require additional sealants. The rubber coating on the gasket provides the necessary sealing. Always refer to the specific instructions included with the kit or the vehicle's service manual.

Yes, these gaskets are engineered for high-output naturally aspirated and boosted (turbocharged or supercharged) machines, making them suitable for applications requiring enhanced sealing under extreme conditions.

The lifespan of gaskets depends heavily on proper installation, engine operating conditions, and maintenance. However, Cometic MLS gaskets with EST technology are known for their durability and ability to withstand demanding use, often outlasting standard gaskets significantly.

The kit includes all necessary base, head, and cylinder O-rings, along with other top-end specific seals required for easy removal and reinstallation of the top end of the engine.

These Cometic gaskets are proudly made in the USA.

Double-check that all electrical connections are secure and that the ignition timing is correct. Verify that the camshaft timing is properly aligned according to the service manual.

Confirm that the cylinder head and block surfaces were perfectly clean and flat before installation. Re-check the torque sequence and values for the head bolts. Ensure all O-rings and seals were installed correctly and are not pinched or damaged.

Verify that the cooling system is functioning correctly, including the radiator, water pump, and thermostat. Ensure there are no air pockets in the cooling system and that the head gasket is not compromised, preventing proper coolant circulation.

Re-inspect the mating surfaces for flatness and cleanliness. Confirm the correct torque specifications were applied to the cylinder head bolts. Ensure all top-end components are correctly seated and sealed.
