Cylinder Head Valves 12200-HP7-A01 for Honda Foreman TRX500 Rancher TRX420 ATV

Cylinder Head Valves for Honda

These cylinder head valves for Honda are replacement engine valves that open and close the intake and exhaust ports so combustion gases move in and out of the cylinder head as designed, and they reference OEM part number 12200-HP7-A01.

Overview

These cylinder head valves for Honda are direct-fit replacements for worn or burned valves in small-displacement ATV engines. Each cylinder head valve is machined to restore proper sealing and compression, helping the engine idle and run the way it should. They suit riders and mechanics rebuilding a top end on Honda Foreman and Rancher models.

Specs At A Glance

Good To Know

Q: Do I need to lap these valves after installation? A: New valves should be checked against the seat and lapped or ground as needed so they seal correctly before the head goes back on.

Q: Can I reuse my old valve springs and retainers? A: Reusing them is possible if they fall within spec, though measuring spring free length and inspecting retainers is a good idea during any top-end rebuild.

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