In Part 3 of our Project Vespa series, the OLD GUY FUN garage gets down to the gritty work of cleaning and preparing the engine components for a full rebuild.
We tackle a "seizy, greasy, grimy mess" using everything from Simple Green to ultrasonic cleaners.

This episode is a deep dive for motorcycle and scooter enthusiasts and DIY mechanics who want to see the real-world process of:

Engine Case Cleaning: Scrubbing years of grime off the casings.
Bearing Installation: Using the "oven and freezer" trick to press new bearings.
Cush Drive Rebuild: Drilling out old rivets and upgrading to a PX200 spring configuration for more power.
Clutch Overhaul: Compressing and rebuilding the clutch with new cork and steel plates.
Whether you're restoring a vintage Piaggio or just love garage builds, these tips and tricks will help you prepare your project for reassembly.
