Metering Valve Rotor (K-style)
These rotors fit the K-style metering valve. Also called a "piston" or a "spool".
Choose from: A - Blown alcohol, B - Tunnel Ram, C - Blank
The blank rotor has no holes drilled for idle or pressure relief or channel cut for idle. Tailor your off-idle/partial throttle performance by cutting your own groove. These rotors are soft steel and can be ground, filed, milled, drilled, etc. Make it just like you want it!
