Adjusting for weight is basically just bumping numbers till sag hits what you want.
Setting up suspension on the other hand is a mysterious & secretive task that you can only learn once you get the secret handshake down
I set my sleds with about 1-2" of sag with rider on at each corner. how you get there up front is pretty simple unless you've got the limiter sucked way up which puts more weight on the skis.
Have rider hop on, and bounce on sled a few times. Where it sets is your sag. I measure sled all the way up (lifting sled to top of shock travel), then do it again with rider on & I want about 1-2" sag for how I ride.
Balancing the skid setup is MUCH more rider preference, and I'll say right off I set my sleds different than most, so don't assume what I do will be ideal.
I set my sag using center shock primarily, and then set transfer using torsions, and dampening. I also run my limiters out till it's too much, then bring them back in one notch. When I've got a new sled, I bring an impact with the size the limiter is along (13?) and I'll just test & change it in the field however many times I need to to get it right.
My sled runs 5 center, 2 rear, and limiter one hole from all the way out. I like my sled to stand up when I'm crossing a creek, when I need to do a quick tail turn, or whenever I feel like giggling a little bit.
My stock ski shocks were at 5 with swaybar disconnected, probably 3 with it connected, but I got rid of it fast.
I run 3-4 more psi in my pto side ski shock btw, the sled is heavier on that side.
I'm 5'8" 188 lbs, I carry a small avy pack with a lot of survivial gear in it, but not much extra junk otherwise. I like to climb, ride trees, and jump.
