Well, I hit the snow yesterday with this.... and UGGGG brutally sad day! I spent limited time tuning as 20 minutes up the mountain brought us to the scene of a fatal accident. That's for another post.
The low down...The stutters are felt and the bigger bumps blow through the travel. Sounds like a stock as delivered 08 RTX, eh? This is a real let down after the recently successful respring and valve of my buddy's Apex GT Mono.
In my 136" dual shock I have multi stage valve packs, stock 3.0kg/180lb front shock spring with no preload, stock rear springs on medium, stock location coupling blocks. Both straps are on last hole (full extension). My low speed comp is adjusted full soft. I began turning the high speed up with some improvement in the bigger stuff, but then the above mentioned accident put a damper on things all together.
Other things of note, the sled hooks well w/o lifting the front. Rebound was easily adjusted in w/ no kick back...
I guess before I jump in I'm looking for direction here. I spent some time searching through the FX Nytro forum. It seems to me I am missing something, my first stage valve stacks and stock springs should at least be light enough to eat the stutters.... Thoughts, coupling needs to change due to length?
Thanks....

Is the stock center spring 2.5kg on the RTX???
Well, turns out that the 3.0kg/180lb spring is the optional spring, and on the center shock is much too firm for trail riding. The custom center shock I built has just enough length to take a 4" long tender spring on top of the 8" main spring.
Today a 140lb tender with crossover slider joined the 180 main... large difference. The stutter bump ride quality improved quite a bit, not perfect, but getting there.
The sled was still blowing through the rear arm travel on the bigger hits. Cranking up the high speed dampening eliminated the bottoming, but made for harsh hits... that means a little more spring rate and less high speed comp dampening may be in order. Sooo, I threw a set of the 214kg torsion springs in, lowered the high speed knob and took it for a rip.... ahhh... we're in the ballpark now, quite rideable..... more to come.
