Possible Rear Skid/Shock Issues?

[Elyshiwa]

I'm new to the forum so I apologize if this topic has already been discussed. I haven't found it yet so I thought I would write a new one.

First off, I have a stock 2009 Nytro MTX and I noticed last year when I rode that the rear shocks/skid would stay almost all the way compressed after you got off of it. I have the settings in the middle (just as they came from the factory). You would have to pull up on the back of the snowmobile to get it to return. Anybody else having this problem? The guys at the local shop where I bought it said it just needed greased. But after they did that it still didn't help.

Any suggestions would be appreciated. I would love to put a new skid under it but I don't have the cash atm.

Thanks

Sounds like the shock is toast. Remove them from the skid and see if they have any resistance when you compress them.

Discussed is a an understatement, I am not shure there is anything that you can do other than carry a good shovel. As you will find out the stock skid and track are not that good, but dont worry it can be easily fixed for around $2000.00. Sorry I dont there is a quick easy and cheap fix for the problem.

shocks do not return the suspension to ride height. they are dampers to absorb impact and rebound.

the suspensions return to ride height, is limited by the strength of the springs (not the shocks).

you'll need to crank up the spring, and or get torsion spring spacers from hygear. or get stiffer springs to get your suspension to return to the top.

Thanks for the info. I was going to go the route of stiffer springs and see if that helps, but I wanted to hear if there was any other thoughts.

Hopefully some day I can get a new skid!

With stiffer springs, will anything need to be done to the stock shock or replace it alltogether.

 

[woodsrider]

Ski was right, the problem is the springs not the shock the shock should still be okay. You just need a heavier spring set. I had the same problem.

 

[fiddlersgreen]

Did you go with the 1500nm or 2100nm springs. What did it do to ride quality.

 

[woodsrider]

Actually I went with 1700 or 1750's. Depending on how big you are I'd go with the 2100's. 1500 would be too lite IMO.

 

[fiddlersgreen]

I know you can get 1500 and 2100 but I was not aware of the 1700-1750. The 2100 is for the apex are the 1700?

I am 250lbs geared up with 20L of gas on the back all the time.
They're not cheap. $165 each from the dealer. Well worth it though if it fixes the problem.

 

[woodsrider]

I weigh 250 lbs also. If you ride alot of trails and they are whooped out and you're an aggressive rider go with the 2100's. Where I ride most of the time is off trail and when i do ride trails they are groomed well.

How much ice is built up in the skid when this happens? I have also had shocks that got water in them cause the rear of the skid remain compressed. Jmo

I'm not quite sure on the rear suspension of these sleds, but if the MTX uses torsion springs similar to the short track sleds, just buy a set of X-Click 4 position billet spring blocks. They replace the plastic 3 position
(S M H) blocks on the rear, and the X-Clicks have a 4th overload position for even more preload on the springs. I used mine all last season and ran them on the 3rd position, and they provided better resistance than the stockers on HARD, plus I still have that 4th overlaod position available. I believe they were in the $50 range, much cheaper than buying new springs.

Here's where I bought mine...

Me too. I had the same problem with a Cat. Had to get the shock. The skid would compress and stay compressed till it thawed.

I don't think this is the issue here. The skid has movement just not much resistance to bottoming.

 

[woodsrider]

I doubt very much he has a shock issue. The stock springs are just too light for bigger guys.
