I am having troubles on getting the 50/50 rod gap on my rear suspension. I have my center spring almost maxed out (most preload), FRA in the middle, have the rear spring all the way backed off (1" of threads showing), and i have my straps let loose(about 1/2 threads showing past the nut).

The way it is set-up now i have about a 90/10 rod gap and the rear of the skid is off the ground about a 1 1/2" when sitting. Any suggestions??

also, the msrx has 136" suspension and has the pro-action long travel skid.

I also weigh about 185lbs...

loosening your center spring should help to get the gap if you are saying that the bigger gap is on top of the control rod slide tube. (The tube with the grease fitting in it).
 
I beleive you should tighten the limiter strap back up to get skid level with the ground. I have a 2000 Venture skid which she be about the same. I have front spring almost maxed out FRA in the middle. You will want to check gap with you laying over the sled seat with all your weight on sled and adjust rear spring to get your 50/50 gap. I think I am correct on this.

yamaholic22, i read a few of your posts on your set-up. I seen you said to max the center spring out, fra in middle and adjust rear for gap. Did you tighten your limiter straps to get your skid level?? If not how did you have them set?

Shoud i put the fra in the soft setting??
 
I do like to run quite a bit of preload on the center spring, but i also use it as a tool for ski pressure adjustment as well as weight transfer. Yes you can pull up the limiters to get the skid to sit level, but keep in mind you are effectively sucking up some of the available travel of the suspension. How tight are your front springs? Is the front of the sled so low that the rear of the skid must be off the ground because of the teeter-totter effect of the center spring being too tight, limiters too far out, or front springs too soft? A balance is what we are really after here. I would only move the fra to the soft position if you find that when you achieve your 50/50 rod gap, the skid still feels like it is too stiff, like the sled is bouncing more than using its available travel, because the fra changes the geometry of the shock, in essence changing the way the shock damping "feels". It doesn't change the actually shock dampening, but it changes the way that dampening is applied to the suspension system.
 
here is a pic of my front shock..... Also when checking to see if the suspension is set-up correctly, do i lift the sled up then put my weight on it gently, or do i get on it and bounce a few times to set in the suspension, then check....?

That pic of the front suspension doesn't really show how high the front of the sled is sitting with that spring preload, would need a pic of it from the front a little above ground level. When i set mine i like to jump up and down on it a few times so that it is a realistic control rod setting, because when you are riding that is the position it will be in after hitting bumps. The point that it rebounds to is what you want to set it up for if you want a good ride.
 
ahhh, that makes more sense. I was thinking that i had to set it just by setting my weight on the sled. One i bouce a few times like if i was riding it, i get my gap
