Specs At A Glance

Good To Know

Q: Do I need any special tools to install this top end kit? A: A torque wrench and basic hand tools are typically sufficient, but always follow the service manual specs for your machine. Measure ring end gap and piston-to-cylinder clearance before final assembly.

Q: Can I reuse my old head gasket with this kit? A: No, always use fresh gaskets from the kit when reassembling the top end. Reused gaskets are a common cause of compression leaks.

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