have 2016 mtx se 141 " love the sled but im having a hard time keeping it strait on a packed trail wants to dart left to right badly , air pressure set 100 psi in front , any help would be greatly appreciated
 
Is your toe out set correctly? My Turbo Cat (Pro Cross 137 was way out) Set to 1/8" toe out and darting went from extreme to hardly any (completely tolerable). This is when I had the stock Cat Skis, switched to Mohawks, no darting to speak of.

Cut back on the air pressure up front, at 100psi they will be topped out and give you way too much ski pressure. I’m right around 200# with my gear on and find 65psi to be the sweet spot for me. Anything over 75psi really increases steering effort and induces ski lift in corners. The Center spring is a weak 110# spring from the factory which also keep too much weight on the skis, many switch to the 135# LTX/RTX spring or a 160# aftermarket spring. Too much ski pressure really amplifies any toe issues.
 
Looked at the toe in last night and back end is 1"wider than the front , mage the adjustment and rodes like a dream 1/16" toed out and 75 psi front shocks worked perfect thanks guys .
 
Good to hear was an obvious set up problem
