Re: pinging under light load
Your curve info is good for the most part. the late total mechanical is workable with the weights you are running, but is touchy to attain, because it involves "tailing" the straight ramps of the weights.
Tailing is adding a curvature to the end of the straight ramp of the weights, and is touchy to do, best with a bent sander, slowly, a little bit at a time. having a NON-DIAL BACK timing light and degree'd balancer will help.
Depending on the amount of metal removed to make the actual tail, the curve speed is increased, even when the springs are not changed.
Please remember, these mods are only for changing (speeding up) a part of the upper degrees available from a set of weights and center.
Weights 1 is a three set cuts info picture, stock, small change, then more degrees faster as rpm's rise above a certain point. Weights 2 are all 3 weights stacked on each other, pay particular attention to the straight part of the weight that interacts with the center plate. The more curvature, the faster the degrees activate as rpm's rise. It is possible to do this so the rate speeds up for only a very small amount of the actual curve.
