Hooked pulling front wheels then spun

The correct terminology is rebound and dampening. I would think a high end shock would have settings for both.

Setting up suspension for dirtbikes is quite an art. Not one I can say I have mastered unfortunately. The correlation between the settings and effect are often counterintuitive.
For example....if you feel your forks are harsh instinct tells you to soften the compression. But you actually need to increase or stiffen the compression. What is happening is your forks are being compressed more and more with each bump and getting further and further into the spring compression...
It also might be due to incorrect rear shock settings or undersized springs !
