Nice work, used to work on engines, when was a teenager 👍 miss this kind of work.

Very good video. Some drivers have problems with the 2022/23 models. The pistons break under 60h. You also have this experience? Thank you

You missed a very critical step to detail for people watching this video and that is the application of Yamabond or other gasket adhesive to the power valve cover. Without the gasket forming material, it creates an air leak that results in the engine running very lean at lower RPM resulting in lean bog.
