Same rider who adds 23 ounces of flywheel weight to the bike isn't gonna be a guy that keeps it spooled up all day.Its a riding style modification.Some relief their to the added stresses to the original engine design.

If I was contemplating that mod,I would cross reference main bearings and rod bearing sizes between a trials bike engine with approximate cc as what I was modifying.

Factor in the trials bike is much lighter.And is designed to run at a lower rpm with an intake,exhaust and electrical system designed for smooth almost electric acceleration and decceleration.There is no hit and the engine will only rev so high.

There is a cutoff somewhere to how much weight you can add and still expect the lower end to hold up.
