Follow on question relating settings....
What is the cross over point between high and low speed compression?
I think of it in terms of hitting a rock or pothole, compared to undulations in pavement.... that sudden sharp change in wheel position relative to the chassis would be a high speed change, where dips and bumps in pavement that cover many feet of road would take (relatively) a much longer time to cause a change in suspension position.
Do I have that right?
Do I want to set high speed to be more restrictive, or less? Looking to have the chassis remain stable as much as possible. If the high speed can stop movement altogether, I want less, so it moves freely on a big 'hit'...... if all it does is dampen out SOME of the motion, then I may want more to reduce the amount that big hit can move the swingarm. Turn the high speed part into heat, and let the low speed circuit deal with the remaining energy of the motion.
In my head, I envision the high speed compression valving being installed as part of the low speed assembly -- sort of a check valve riding on top of a check valve. The high speed part would have a smaller orfice and a stiffer spring assembly so that it simply rides on the low speed assembly until a sudden sharp pulse kicks it open and lets that energy bleed avway faster than the low speed circuit would allow. It can react faster, up to a point.
Jack it up hard/fast enough, and the small orfice can't allow all of the fluid through, and the low speed circuit will start to act on it as well. As soon as the low speed circuit opens, that high speed circuit shuts, and you carry it the rest of the way through on the low speed circuit.
Does this seem right?
