S&S CYCLE - 90-2025 - Intake Valve - 1.940” - For 79 cc S&S Heads
For engine builders and serious mechanics, the S&S CYCLE 90-2025 is an intake valve where dimensional accuracy directly determines how well your engine runs. Heads are also found on S&S Twin Cam-style motors and use 1.940” intake valves and 1.575” exhaust valves, which matters for a component that operates at extreme temperatures and must seal perfectly against a hardened seat thousands of times per minute. Made in the USA, so the geometry, stem diameter, head diameter, and face angle are held to the tolerances your engine was designed around. Proper intake valve function is essential for full compression, efficient combustion, and clean exhaust scavenging. The 90-2025 gives you the precision needed to restore those characteristics. Sold individually.
