XTX SE - Fox shocks - psi? There is nothing in owners manual

[nickr]

I wanted to set up the Fox shocks on my XTX SE to my weight but there is nothing in the owners manual.

Ive never had air shocks before but the front seems overly stiff and the rear sags quite a bit under its own weight. These are supposed to be adjusted with the little pump thing right? And with the suspension fully extended?

I weight 180 lbs, not too aggressive. Combination of trail, lakes mostly(by lakes I mean bumpy snowy routes to remote areas...no perfect condition speed runs in my area).

A step by set and recommended settings is appreciated.

** Note - I have not tried the sled yet, just sat on it in my garage

When you add air to the shocks be sure the entire front of the sled is suspended in the air, neither ski can be touching the ground. Simply unscrew the plastic cap on the shocks, screw the pump on and pump away. I think 65 psi will be a real good starting point. If you need to let air out of the shocks there is a little pressure release button on the pump that removes air. Simple as that, just be sure there is no weight at all on either ski

what do you have the rear set to? Is it supposed to compress in the rear when Im not sitting on it?

As for the performance of the floats, I had mine adjusted everywhere from 60psi up to 110psi and never liked how they felt. I rode a friends standard ltx a hand full of times with the coil over fronts and they were much more plush and still handled big bumps just as good as the floats. Near the end of the season my floats also were losing pressure over the course of a days time, one or the other on occasion would lose 10-15 psi in a 12 hr time frame. Some guys really liked how the floats were, I personally hated them but it's all going to be in rider preference. I ended up going with a set of coil over shocks on my ltx se because I'm looking for a nice plush ride. Just some things to be aware of. The biggest recommendation I'd have is to keep very close track of the pressure in the shocks. If by chance you see one or the other is not holding pressure, be sure to consult the dealer about it and get them fixed up because 10psi difference from one shock to the other can make for a pretty horrible ride!

Some xtx guys will have to give you guidance there on that one, I'm not familiar with that suspension setup but I do know the xtx guys were very pleased with the ride of their sleds so they'll get u pointed in the right direction

There use to be a chart some where. I'll see if I can find it. Basically I think pressures are set at 75psi in the fronts and 125psi rear. Ride like that and adjust according to your riding feedback. Adjust +-5 psi at a time until you like your settings. Here's a quick video...

YOu will find that 110 lbs in the rear skid shock you may bottom it out depending how hard you ride. You will also notice a bad push in hte corneres if the new sleds have the front skid shock set like last years. You will need to backk off that spring about 5 to 6 turns. Too much and you will notice very heavy steering. I never ran the stock fronts but most guys were from 50 to 65 #'s I was running 55#'s in the main tubes of the evol rc2's

My Viper today and was great.
65 pounds front
front skid shock half way up
rear float 110 pounds

Tip sled on side and do back and one front shock, tip other way and do other shock just do not tip Viper far enough for oil to come out....lol. When you disconnect shock you lose about 5 pounds so set to 70 and remove will be right at 65.

I have my XTX -SE set at 65# in the fronts and 125# in the rear. I cant speak for how it rides yet as we dont have any snow yet. The rear end sags about an inch under its own weight. Im 6'4" 235lbs.

Online instructions from Fox say that when you have reached desired air pressure to not add additional air to account for the air lost when you remove the pump. When removing the pump, the valve of the shock itself closes and seals and then as you continue to unscrew the pump hose when it releases air, that is the air in the pump that is released. When pump is reattached to the shock the air pressure will be a bit lower because a bit of the air from the shock fills the pump back up. Also when tipping the sled on it's side to add air it's not a true reading because even with 1 ski in the air and the other on the ground there is still pressure on the shock. Both skis need to be free of weight at the same time. I got mixed up with that once last year but luckily it didn't take long to figure it out.

If you need to have both skis off the ground adjust air pressure how do you do this on the trail? At home I have a lift I can put my sled on to adjust the front floats air pressure but when I travel up north I don't have a lift or really anyway of getting the front off the ground so there will be no way for me to check the air pressure or adjust it.

You can do this on trail by tipping the sled on its side. There is no need to have both skis off the ground as the two are not connected in any way.

Most have a swaybar. I cheat and do it on ground for setup. I use 3lbs to calculate air loss hooking up gauge. When I am happy with setting I just check the real air pressure at home with lift. Making sure right and left are exactly same.
