OK... i'm trying to understand all the suspension settings. I downloaded the setup file from the FAQ's page. I want to start with Lucky_7's settings because he is the same weight, has the same sled, and rides the same way i do.
-How do I know if I want to speed up or slow down rebound? I’ve had sleds with adjustable compression before, I get that. I’ve never been able to adjust rebound before.
Thanks

This is a good little vid to help you understand how your compression and rebound dampening work, as well as one's effect on the other:

He should have put the compression to 6 clicks before he did full rebound dampeneing.

Rebound: Controls the speed of the shock as it returns to full travel.
Compression: Controls the speed of the shock as its being compressed.

I should have been more clear... I understand what rebound is.
what i want to know is... what are the pros and cons to haveing the shock return quickly, and what are the pros and cons to having it return slowly. i jsut want to undserstand how to tune it better.

If your shocks rebound too slowly they will "pack down" when the shocks are being hit quickly, as in stutter bumps. This reduces the travel available for the next hit and in the extreme will feel as if you have no suspension.
If the rebound is too fast the shock doesn't slow the unload rate of the spring and the skid is slapped down. The effect of this is getting smacked in the butt by the seat over medium sized bumps.
The trick is to get the right balance between the compression and rebound settings that suit your riding. I prefer the compression to be a bit above the midrange and the rebound a bit below.

On the front of a snowmobile you generally dont want to add much rebound to the shock, thats where allot of the sleds weight is and your goal here is to get the shock back to full travel as quick as possble. Compression dampening is better to use here.
On the skid you will generally use more rebound, for instance if you find the back of the sled bucking up over bumps this would be a time to add more rebound to your rear shocks.
Hope this helps

Just for clarification ... when you say "add rebound" - are you saying it should rebound faster?

When I say "add" I mean "more"
Adding rebound results in a slower moving shock.
If you can sometime take a front shock off your sled and remove the spring, start playing with the adjustments and compressing the shock, you'll see right away how compression and rebound effect the shocks movements

I always think about it like this. If your turning the rebound (knob or screw) clockwise your screwing into the seat and resctricting oil flow and therefor slowing down the rebound on your shock. When going counter clockwise your going away from the seat and increasing oil flow which will increase the speed your shocks rebound.
Something my shock guy told me is this... Adjusting your rebound will have an effect on your compression. Whereas compression is only compression. Think about the tunnel adjuster on the mono-shocks. I believe the dial on them is basically a rebound adjuster. That is why most guys like it on the softer settings. By going to full soft you open the rebound all the way and this also decreases compression ( its not a even ratio but it does have a slight effect on compression). I think you need to think about oil flow in a shock as a continuous system. Oil isn't pushed one way and then back the other. If I'm wrong with my description here Somebody please feel free to correct me. I do get confused also when it comes to shocks. I understand it pretty good when I'm talking to my shock guy, but it seems like I have a hell of a time retaining the information year to year. IMO the shocks on the Nytro RTX and RTX SE are maybe the best in all of snowmobiling. My shock guy has my valving down to a T .
From what I've experienced with my RTX I wish every shock on every snowmobile I own had rebound adjustment.

In most cases - yes.Superman said:
But there are cases where the rebound adjuster does really adjust rebound damping and nothing else. For instance, there are single tube shock absorbers with one-way valve equipped rebound adjusters. The one-way valve does not allow oil flow in the compression direction, thus the rebound adjuster works for rebound oil flow only.
