BSA Rocket Three Vapour Blasting engine parts

BSA Rocket 3 Engine Overhaul and Vapour Cleaning

This project is a complete restoration of an early 1970’s BSA motorcycle being restored by one of my customers

The engine is totally dismantled down to bare castings, considering it was manufactured around 50 years ago, vapour honing enabled us to inspect us to inspect the components for excessive wear, cracks or damage, remarkably the engine is in excellent condition
