Product Information
Full details
The Athena Complete Engine Gasket Kit is designed for motorcycle owners and mechanics who require a professional-grade sealing solution for engine overhauls or maintenance. Its primary benefit is the delivery of a reliable, high-integrity seal that prevents oil and fluid leaks even under intense mechanical and thermal stress. While the kit provides excellent durability and resistance to wear, it requires a high level of mechanical expertise to install properly, making it less suitable for novice hobbyists without proper shop manuals or technical experience.

FAQs
Do I need to apply liquid gasket sealant?
Generally, Athena gaskets are designed to seal on their own, but follow your vehicle's service manual as some specific mating surfaces may require a thin layer of gasket maker.
Can I reuse these gaskets if I need to open the engine again?
No, it is highly recommended to use a fresh kit whenever the engine is opened to ensure a perfect seal.
Is this kit compatible with racing fuels?
The gaskets are designed for standard engine fluids; check the compatibility of your specific fuel additives if running high-performance racing mixtures.
Should I oil the gaskets before installation?
Follow the installation guide provided by your motorcycle manufacturer; some gaskets are designed to be installed dry, while others may require a light coat of oil.
What should I do if a gasket is damaged upon arrival?
Do not attempt to use a damaged or creased gasket, as this will lead to an improper seal; contact your place of purchase for a replacement.
Troubleshooting

Verify that mating surfaces were cleaned thoroughly of all old debris and confirm that all bolts were tightened to the manufacturer's specified torque sequence.

Setup, Compatibility & Care
Before installing any gaskets from the P400270900078 kit, ensure the engine block and head surfaces are completely free of old gasket material, grease, and carbon buildup using a plastic scraper and appropriate solvent. Always verify torque specifications in your specific motorcycle service manual, as even the best gasket will fail if the fasteners are incorrectly tightened. During storage, keep the kit in a cool, dry place to prevent moisture-related degradation of the gasket materials. Avoid bending or folding the metal-reinforced gaskets during handling to maintain their specific shape and sealing profile.
