My other motor with less cam, less compression, and a stock crank. Responded to rpm a lot better than this motor. It was half a second between bracket mode and race mode. This motor was only two and a half tenths. That's shifting 1000 rpms short and running taller tires.
It might go quicker with the stock crank.

Art, I believe you will not notice that much of a change in performance.
Nevertheless, if you want to get the best out of the crankshaft, I would suggest your crankshaft to have some weight removed and probably change the shape of the counterweight and have the lightening done properly.
My choice and recommendation is Shaft Tech:
