ATHENA Top-End Gasket Kit — Manufacturer reference: P400485600115/1
This ATHENA top-end gasket kit includes all the necessary gaskets for reassembling the cylinder and cylinder head, designed for engine refurbishment operations on motocross machines. Ideal for cylinder/head disassembly, it allows for the replacement of worn sealing elements to achieve a clean and compliant assembly. The kit notably includes the valve stem seals essential for the proper functioning of the distribution components.
Replace the gaskets before performing the final tightening to ensure sealing between the cylinder, cylinder head, and valve shafts. Check the list of references and parts necessary for your model before assembly. This kit provides the sealing foundation for a top-end ready to accommodate the piston and rings after revision.
