Here is a short video documenting the process of freeing four stuck pistons from `72 750. I am currently apprenticing with Richard Barsotti at Wasted Spark Motorcycles, and this is a project for a customer. I also have owned a `71 cb750 for a decade now, and was extremely exited about this complete teardown and rebuild. Mostly uncharted territory for me. Ill post a new video as progress persists.
enjoy the video here.
