do you still have the sled? the only thing i can suggest is take the timbersled front end off, stock is alot easier in deep snow for carving and sidehilling, the front end does turn tighter but it doesnt hold a sidehill as good as stock as for the back suspension i have no clue i run holz coil over out of a polaris on mine does everything i need it to, my dads is all stock except the light pod is taken off an the exhaust is a glass pack we made but it pulls just as hard as a turbo, climbs harder than an m8 out pulls an dragon 800 an xps are no competion dnt jump ship yet there is so much info on this site an so many people are willing to share their info from experiance to get u back on top to just quit, two smokes are outdated technology
