2012 Nytro XTX Back End Sag(With Pictures)

[Matthew457]

Here are some pics I took this weekend of the sag on my 2012 nytro xtx. I took the back end and pushed it down as far as I could and it stays there by it self(the first picture shows this and it is about 22 inches from the ground) the second picture is of when I pulled the back end up as high as it goes and it does stay there by it self( second pic shows the back end 26 inches from the ground) So this means that it sags about 4 inches. Now the next 3 pics I have is the dual shock when the sled it pushed down as far as it can go and it stays there, in the pic I am not pushing down, that is just the height that it rides at pretty much.(As you can see there is about 1 inch of shock absorption left) And the last two pictures show the sled sag(picture one) and then when I pull it up all the way and it stays (picture two) Preload cam adjusters(I believe they are called) are on hard. Brought the sled to the Yamaha dealer ship and they said this is normal for nytros and they hardened my suspension. Seems not right but I guess if they say it is then its gotta be alright!

When was the last time you greased the entire suspension. The transfer rods don't really have much to do with with ride quality and minimal effect on ride height. They do affect it but not a huge amount. All they do is change the weight transfer from front to back. With the nytros you can't really judge right height with a cold suspension. Mine sags around 2 inches when its cold. Ride it for a hour or so and that number drops to 1" or less.

That was right after riding for 3 hours. Usually it's worse after riding. And by "grease the suspension" are you talking about puting grease into those little metal things that stick out of the suspension and a-arms and all that?

Yup

Those little things are grease fittings. You should get a grease gun and some synthetic snowmobile grease and give a couple of pumps into each fitting every few rides. Also put a bit of lube on the torsion springs where they slide through the guides behind the outer idler on the slide rail. Those are not shock absorbers that you are looking at. They are transfer rods. You should look online to learn how the suspension works and tips for setting up sag according to your fully dressed weight.

 

[Matthew457]

Yup

I did it this weekend, maybe not enough though. How do you know when it's enough? I put like 3-5 pumps into each one

You will see the old crappy grease squish out. They don't hold a lot.

Out of the fitting or the shock?

You are not greasing the shock. You are greasing the pivot points of the suspension linkage. You need to get on the Internet to understand suspension and how it works. There is a ton of info free for the taking. Google snowmobile suspension and read a bit. Even how to maintain it through manuals. Good luck.

I grease mine 2 times a season with low temp grease and the suspension action is great. Very little sag with preload on medium.

Alright, maybe they're pretty low or just shitty grease in there. I'll pump a crap load in the next time I get the chance! Haha

LMFAO!
Go on Ebay, buy a service manual- they are in both paper & CD forms... Easiest way to go about learning your sled's parts & how to fix things when they break...
