One of these days, I'm going to have to do some YouTube videos about rocker geometry. There is some good basic info in these, but also much that is incorrect. I wonder if either of these gentleman can explain how the centered pattern improves reliability or performance, or any other benefits. Also, if the rocker ratio is changed by changing the pushrod length, why is there a need to sell multiple rocker ratios. Just buy any old rocker and set it to the ratio you want. If only it were that easy.
