Piston Port vs Reed Valve Pistons | Engineering Differences & Machining Process

We’re often asked about the differences between pistons used in piston ported engines and reed valve engines, so we thought we’d make a video explaining it. In this video we take a closer look at the key differences in piston design and why they matter depending on the type of engine setup. We also show the process of modifying a piston for use in a reed valve engine, including the machining work involved and what needs to be changed to make it work correctly. If you're building or tuning a Lambretta engine, understanding these differences can help make sure everything is set up properly and performing as it should. https://www.lambrettaspares.com/
