Good To Know

Q: What is included in a top end gasket kit? A: These kits typically cover the gaskets and seals used when removing the cylinder and piston, such as base, head, and related sealing components. Check the listing contents against your job before ordering.

Q: Do I need to replace gaskets every time I open the top end? A: Yes, gaskets are designed for one time sealing and should be replaced whenever the cylinder or head is removed. Reusing old gaskets can cause leaks and loss of compression.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
