ATHENA Top-End Gasket Kit (ref. P400485600116)
This ATHENA gasket kit includes everything essential for reassembling the top-end: cylinder and cylinder head gaskets, as well as valve stem seals necessary for proper assembly. Designed for motocross applications, this kit simplifies the restoration during an engine overhaul or maintenance operation after cylinder removal.
Convenient to have in the workshop, this kit allows for the replacement of all top-end sealing components at once when replacing the cylinder or cylinder head. Before reassembly, check the condition of the mating surfaces and follow the manufacturer's torque and cleaning recommendations to ensure proper sealing.
