FAQs
What models and years is this gasket kit compatible with?
This Athena Top End Gasket Kit is specifically designed for the Honda CB 750 K models from the years 1970 to 1975.
Does this kit include everything needed for a top-end rebuild?

What is the benefit of having multiple base gasket thicknesses?
The different thicknesses of the base gaskets allow you to adjust the engine's compression ratio. This is useful for tuning performance for different types of fuel, such as standard gasoline or higher-compression race gas.
Is this kit suitable for a beginner mechanic?
While the kit contains quality parts, engine top-end work requires mechanical experience. It is recommended for riders who are comfortable with engine disassembly and reassembly, or to be installed by a professional mechanic.
What is MLSS technology?
MLSS (Multi-Layer Steel) is a type of gasket construction known for its durability and superior sealing capabilities, making it ideal for high-performance engine applications.
Troubleshooting
Engine misfires after gasket installation
Double-check all gasket placements and ensure correct torque specifications were followed during reassembly. Verify that no extra or leftover parts were omitted during installation.
Oil or coolant leaks from the top end
Inspect the sealing surfaces for damage or debris. Ensure the head bolts and base bolts were torqued to the correct specifications in the proper sequence. The head gasket or base gasket may need to be replaced if damaged.
Compression is lower than expected
Confirm that the correct thickness of base gasket was chosen for the desired compression ratio. Review the engine's service manual for optimal gasket selection based on your tuning goals.

It is recommended to consult a service manual for detailed step-by-step instructions.
