Good To Know

Q: What is covered by a top end gasket set? A: It supplies the gaskets and seals needed to reseal the cylinder head and cylinder on your Moto-4 200. This set also includes valve seals for oil control at the guides.

Q: Should these parts be replaced whenever the top end is serviced? A: Gaskets and valve seals are normally replaced once the head or cylinder is removed. Reusing worn gaskets can cause leaks or a drop in compression.
