shock set-up

the shocks dont seem to be binding, but i haven't shecked the pillow ball retainers yet, will do that right away..... as for the spring preload adjustment..... i have tried every different setting and still no rebound, so how do i find out what lbs. these springs are and where do i get stiffer ones?


and if i want to fully rebuild my shocks, what is a good wheight oil to use? i figure i should just stick with the 2 hole piston...... or not?
