Aprilia SR50 70cc – build + test + Athena Racing | baza pod dalszy tuning 🔥

In this episode, I assemble an Aprilia SR50 70cc engine using an Athena Racing cylinder, a Polini 21 carburetor, and a Yasuni R exhaust. I show the entire build process step by step – from parts assembly, through a discussion of the setup, to the first start-up and test ride. This isn't a full tune-up yet – some components are stock, but the entire setup provides a solid foundation for further modifications and project development.
