2016 ltx Dx
Changed skies to curve and put Bill spring in.
Sled is all over the place.
1/8 toe out
4 turns on center spring..
Darting very bad
Let off the gas in corner and the back of the sled wants to come around studded track and 6 " carbides.
Weight 240 without gear.
Where should I start for adjustment.?
Ok what do these do
Like if you put more turns in center spring what will it change in handling on the sled
Same thing with front springs more preload will do what?
Less preload will do what?
Rear spring what will that do fro handling.

My sled is a rtx 129 “ track. I have the coil over shocks all around.
I found everything was way stiff. So here’s what works for me.
I found that if the front springs were too stiff, the sled got tippy feeling in corners. I loosened them so the spring rattled with weight off skis. Then tightened just enough to stop the rattle. Couple of turns. Then rode it and gradually turned them a turn until it felt good. More preload- more effort in corners. It’s a give and take.
Limiter straps- I tightened them 1 hole - they are on the second hole
Center track shock, loosened that just as the front ski shocks. Until it was rattling with back end hanging. Then tightened collars to just load them. I have around 19 threads showing.
This is about the best I can get. I’ve spent a couple of days, gradually adjusting.

My 15 ltx dx did the same thing when brand new.
Your center skid spring is probably to tight causing the unbalanced feeling when letting off the throttle.
Let out spring until loose then turn 1 revolution and start from there.
Same thing for front ski springs.
I have curves also and they dart with single runners.Install there leader.
The way our shocks are valved require very little preload on the springs.
You will bottom out on nasty bumps but that’s what a dx model does.

Your center shock spring is turned up to tight that causes the loose rear end. If your ride height is low turn up the rear spring that will work also.
Those rich punk kids in the video are mountain riders not trail riders.

Ok here’s the deal.... in video #4 that’s a setup 100% for mountain riding, that setup on the trails would totally $uck for handling in the trails period especially with studs. Mountain guys run a much softer setting on the Center spring in order to climb up onto the softer snow. Even track weight distribution is NOT what you want with most trail sleds, they will push badly. You want about 75% weight on the Center shock give or take for conditions. I don’t use scales or any of that rich kid stuff, sled handling and feel is what really matters. Trail conditions change and as you notice what the sled is doing make adjustments. Scales make me feel fat anyways! Lol

Oh one more thing on darting. Aggressive skies will dart some no matter what you do. Once you turn you Center spring down that should help. Darting has never put me in the trees it’s something you need to get used too, or go ride with the Girl Scouts.
The reason why a lot of stock sleds push through the corners is they have skies that are very shallow (non aggressive). This is due to so many complaints about darting by customers. So they put these wimpy skies on so I have to go buy new skies for my new machine right off the bat.
Ok here’s a good example...
My girlfriend used to complain about darting continuously. I did everything to try and stop the issue but the sled either pushed or darted. Then we took a long trip of 250 miles. She was Bitching about the darting for the first half every stop. She was so tired from fighting the darting she gave up and said F-it the second half of the trip, she really had no choice she was too tired. After that trip she rode noticeably faster and didn’t complain any more about darting. She had finally realized just to go with the flow and not worry about the front end skipping around a little.

Isn't "Bill's" spring a 160# straight or something like that? As I recall he was trying to get some weight off the skis on his NON coupled XTX/MTX sled as he is an off trail/powder rider.

Read his first post, certainly don’t sound like powder riding to me.
He has the Center spring turned down quite a bit must need more rear spring to even it out.
Coupling don’t matter unless it’s bumpy.

I take Bills spring to be former member Stingray. He added a heavier center spring to enhance his powder riding ability.
The OP is likely finding that this is just too much spring for a set up trail regardless of preload as the RTX and LTX use the progressive spring.

Sounds like a recommendation old StingRay would make! Lol that’s the stupidest thing I’ve ever heard! You never want the Center spring stiffer for riding powder! Wow but you know StingRay he never was wrong about anything.

Just turn that Center spring all the way down and the rear spring up. That should help enormously.

One other thing to check is the rubbers to make sure that you have the correct ones. Curve has had lots of confusion as to spacer thickness, rubbers etc.
Slim Jims are also supposed to help a lot, but we've had such poor snow I haven't even bothered installing them.
If I had it to do over I'd probably do Cat skis and snow trackers over the curves. Ugly but highly effective and acts like power steering...
