Stock crank vs. modified (stock) crank...
Does anyone have pictures of an SR crank, stock or otherwise? It's looks to me like the crank in this new motor has been knife edged/balanced.

But in order for me to know for sure, I'd like to compare to a stock crank.

Thanks!

These are all images of stock cranks? Or have they been worked?

Is the JGY one an untouched crank?

TO make it short... these are all stock crankshafts (except JGY which is "polished and remaned") from google.

Your search skills are weak.
