Has anyone softened up their R's suspension to make it more off road friendly.

Saw the post on the xr400 shocks which interested me. Are there any other yammy forks that are straight swap? All the modern yammy trail bikes I can think of are upsidedown forks.

I'm also keen to know if anyone offers after market springs for softening. all the springs i've found so far are for stiffening.

Cheers
