own a terralander 625 that is has too stiff. should i adjust the length of spring order to make softer?
Also, shock absorber has an AIR intake that never used it and do not know what inflation measure should I put in PSI.

 

if its to stiff i would say it has to much air..

 

I think shocks are charged with nitrogen not air. I suppose you could try less.
Stock shocks are stock shocks. I doubt you'll have much luck improving the ride much.
