Power Valve Channel Restricter Kit

The Power Valve Channel Restricter Kit from Advanced Engine Design is designed for performance enthusiasts and engine builders who require precise control over power valve function in modified four-stroke engines. This kit addresses critical tuning variables that can arise from various modifications, ensuring stable mid-range torque delivery and simplifying carburetor jetting.

The restricter limits the volumetric flow rate through the power valve channel, allowing for precise metering of power valve flow. This graduated restriction enables users to tailor power valve opening characteristics to their specific engine configurations, including displacement and compression ratio, without the need for costly carburetor modifications. Constructed from lightweight aluminum, this kit resists corrosion and is designed to fit cleanly into the OEM power valve bore.

Engine builders and mechanics working on performance tuning will find this kit invaluable for optimizing engine performance. It is particularly beneficial for those fine-tuning rebuilds or dialing in competition engines, ensuring compatibility with various four-stroke engine designs.
