What does 'Special Application Crankcase' mean?

This means the crankcase is designed for specific, often custom, engine builds rather than a standard factory setup. It typically accommodates unique crankshafts or configurations, like the small diameter flywheels mentioned here.

What is the significance of the 4-1/8 inch bore and small diameter flywheels?

The 4-1/8 inch bore indicates the size of the cylinders the crankcase is designed to accept. Small diameter flywheels can affect engine balance and how quickly the engine revs, making this a choice for performance-oriented or custom builds.
