Interesting Skid Shock Spring info

[stingray719]

I'm just waiting for someone to get some REAL seat time in and compare both when using the XTX as a flatlander would. Initial impressions are one thing. Long term is another.

Not trying to offend you so please don't take it that way, but you do not own an XTX so I am puzzled why you are trying to rain on our parade?

Stingray, when you say 1/3 from the bottom what is your reference point? Bottom of the spring it self or bottom of the locking adjuster?

I'm just waiting for someone to get some REAL seat time in and compare both when using the XTX as a flatlander would. Initial impressions are one thing. Long term is another.

I also had very heavy steering and really don't like that feel. I prefer to use body English to corner and control inside ski lift, its a style that comes from my motorcycle racing days. In my local area I ride ditches and long straight groomed trails, rough cross country at times and river running. I just put in the 135# spring with bottom lock adjuster 1/3 from the bottom thread. Limiter is in stock location (top hole on back side of strap and middle hole on front side of strap). Front Fox shock at 65psi and Rear Fox shock at 135psi. Also clutched it with G-W-G in primary with 2mm spacer, 8FP weights with 3g rivets in the tip, Dalton 46/40 helix with 0.085" rebated out of the spring seat, pink secondary wrapped at 6-1 and OSP belt adjuster. Have not had a chance to try it but will hopefully tomorrow. Should be a different animal now

The XTX in my opinion has too much weight on the front, and cranking the front skid shock adjuster up more than half way bothers me. On the girlfriends XTX that we long tracked I drilled different holes to solve this, but on my Viper I put Ice Age rails on it and they have windows where I would need to drill holes. So off I go to try to find another solution.

I start by tracking down the stock spring on the shock on my XTX
1704-236 110pounds

Now I download the chart and look for a spring I guess will work and find it
1704 461 135pounds

Where it gets interesting is that a search on Google also shows this 135 pound spring on the 2015 rtx and ltx Vipers. It also shows this spring on the 2014 XF7000 Cat. Yet the 2014 XTX got the 110 pound spring. See info on the bottom of this thread I copied.

So I have ordered this spring and will put it on my Viper and see if it then handles as I expect it too. Evaluation to follow.

Please correct me if any of this is wrong, as I gleaned it off the net and you know.....the net is not always correct.

Hi Stingray

Is the ltx se rear suspension are the same as stx dx? I made revalving on my ltx se and I'm curious If I could try those shocks on my stx dx ? I think the center rear shocks should be the same but I'm not sure ??

 

[stingray719]

Stingray, when you say 1/3 from the bottom what is your reference point? Bottom of the spring it self or bottom of the locking adjuster?

I originally set 1/3 of the way up the threads. After fine tuning I am at about half of the threads, and may put yet a stiffer spring in for MY fine tuning. I still suggest the 135 spring to start and fine tune from there.

Your ltx should already have the 135 pound spring in it.

Hi Stingray !
If I want to try 145 lbs spring From AC wich number for my stx dx ? I tried to switch my shock From my ltx se to my stx but the shock is not the same lenght as the stx

 

[1049triple]

Did the 110/to 135 spring swap and set the preload at 1/3 of maximum. Helped. Very happy in normal snow conditions. When the snow became crusty and harder, it is still a little wicked. I will put more preload on it when I had the time but for now it work great and better than stock. This is with the stock skis and the limiter in the center hole on both side of the tube. When I put the C&A XTX's skis on it it is still WWAAAYYY to heavy!
For now I want to modify my C&A XTX's by first shaving the center keel from 1" to 7/8". If I can make them less agressive, then I will fine tune with the front skid.

 

[turbo800]

I had the same problem with my 8" Slydog Pounderhound's. I had to crank the center track spring back up to where it was set stock with the 145# spring to make it manageable.

 

[1049triple]

How does it feel on the bumps cranked like this? And how about the limiter position?

 

[turbo800]

It handles well in the bumps and the limiter strap came in the loosest position. I ended up taking the Slydog's off last weekend. We didn't have enough fluffy snow and they were hard to sidehill. It was an all or nothing situation. When it would roll over, it was all the way on its side so I decide to go back to stock. Well for Christmas we got 2+ feet of new snow, so I'll get to see how the stock skis float. If they suck, I'll go back. I noticed the distance behind the spindle on the stock ski is alot shorter than the Slydogs, they should countersteer better in theory.

We have the old style Camoplast blow molded "All Terrain Skis" modified to fit our Vipers and really like them. They are very much like Polaris Grippers but wider. Great for deep powder snow and good for roads and trails, and they have that light steering feeling.

 

[turbo800]

Yes, you've mentioned them before...

Here's where we ride...................... now you see why I want more weight on the skid instead of the skis
