Hello Jake,

Regarding to the 4lbs lighter than stock (billet) crankshaft, plus the balancing of the entire rotating assembly.

Would be possible to achieve similar results by knife edging a stock crank (removing weight) and thereafter balancing the entire assembly as well?

What would be the down side of knife edging a stock crank?

Is the main reason for having the lowest possible mass rotating assembly is to be able to sustain higher rpm with the less vibration? Making a stronger engine in the end?

Your comments are always appreciated, thank you.
