    JIMS Manual Compression Release Valves

    Ease your starts with Jims Manual Compression Release Valves, a pro-grade add-on for high-compression Harley engines. These valves vent cylinder pressure with a tap, making it easier to crank your big-bore motor without killing your starter. Easy to install, they thread into specific Harley heads, offering a quick upgrade for riders building hot engines. Built from tough steel, they handle heat and pressure, ensuring reliable releases ride after ride. Perfect for custom builders or performance junkies, they’re a must for taming high-compression beasts. The manual design gives you control, letting you pop the valves when needed for smooth starts. Trust Jims to make your Harley’s big heart easier to fire with these precision valves.

    • Install these in your high-compression, big-inch motor and give your starter some help
    • Install by simply drilling and tapping each cylinder head and thread in the self-sealing release valves
    • Can be installed in all Big Twin, XL and Buell motors
    • Made in the U.S.A.
