Its pretty easy to change the frequency just by changing weight.. I cut down most of my
cranks to bring the rpm up(changing the frequency)
Very cool. Thx mr P. What about 2 , otherwise identical cranks, but 1 has regular shaped radiused counterweights, and the other has pendulum cut cw? They are identical weights, lets say, but they woukd have totally diff frequencies, right?
Not really.. weight is the factor so if they are the same weight then the frequency should be the same.. I
never did any of the fancy shapes but if one allows the oil to slid off easier it would be less weight...
less weight would allow the crank to accelerate quicker.. one thing I did was to knife both ends of
edges of the crank so it could cut through the air easier... think of a sail boat hull in the water
