FAQs
Does this kit include seals for the bottom end?
Yes, this is a complete engine gasket kit, meaning it contains components for a full rebuild of both top and bottom ends.
Do I need to use additional liquid gasket or sealant?
Only use liquid gasket where explicitly required by your manufacturer's service manual; over-application can interfere with the precision fit of the Athena components.
Are these gaskets reusable?
No, engine gaskets should always be replaced with new ones whenever an engine is disassembled to ensure a proper seal.
What makes these gaskets different from OEM?
Athena gaskets are engineered for high-performance off-road conditions, featuring improved resistance to humidity and extreme thermal stress.
Is this kit compatible with all engine sizes?
No, this kit is model-specific; ensure you verify the compatibility with your engine's year, make, and model before installation.
Troubleshooting
Visible fluid leak after installation
Check that the mating surfaces were cleaned properly and that all fasteners were tightened to the manufacturer's specified torque sequence.
Engine losing compression
Verify the head gasket orientation and check that the cylinder head surfaces are perfectly flat and within service limits.

Setup, Compatibility & Care
Successful installation depends on thorough preparation of the mating surfaces. Before applying any gasket from the P400250900071 kit, ensure all old sealant, oil, and debris are completely removed from the engine casings using a non-marring scraper. Always consult your specific motorcycle service manual for torque specifications and tightening sequences; uneven torque is the most common cause of premature gasket failure. Store unused gaskets in a cool, dry place away from direct sunlight to maintain their material properties. When installing, ensure surfaces are clean and dry, or apply a thin layer of appropriate engine assembly lube if specified by your manufacturer's manual.
