Yes it helps if a bit of lube is sprayed on time to time,,
Turn the jack up plate, harder or softer.
i have backed mine right off,(gen 2 )standard spring,i was being thrown up from the seat,i live out in the sticks,roads like roller coaster.
I have checked the full adjustment of the damping and have now set it in the hard,slow position and i just tried it and its miles better, so the damping is still working on my bike.
