Ski Pressure - Part 2 - Success!

- This is the conclusion video covering ski pressure and how to adjust it.
This video applies to all makes and models of snowmobiles made after about 1980. While I used an Arctic Cat Riot to demonstrate, you can take the information in both Part 1 & 2 and apply it to your snowmobile.
Steering effort on my Riot was a bit excessive, and I had concerns about safely maneuvering on trail, especially when other riders take it. In Part 1, I tried to explain how the suspension works, particularly when it comes to ski pressure.
In this video, I’ll show you how to make adjustments and then take it for a test ride. I was satisfied with the result and hope you enjoyed this 2-part series. - Авто та транспорт
Suspension adjustments can be as challenging as you want it to be. In Parts 1&2, I tried to simplify it by focusing on one aspect and solving one problem. I tried to be generic enough that anyone can use this information. For those who wish to comment with suggestions, please do - we can all learn together.
By the sounds of it, you wanted a trail sled. After you go past 136 ish they purposely designed them to have very little ski pressure across all settings. I mean, you can make it a little better, but it's not going to handle like a trail sled at all. Never will.
Ski shocks loose or on the softer side. Limiters straps loose as possible, front skid shock tight or cranked most of the way up and the rear skid pre load set on 1 or 2 or soft to moderate. Then you'll be able to steer the track and ride on top of the snow vs plowing through it because of the down force on the front of the sled.
Great advice! Thank you!
You want to run front track shock as loose as possible. I run about 1 inch of preload on my lynx rave. Front track shock also affects riding comfort if too stiff it'll be like riding a pogo stick and sled won't pivot properly or transfer weight properly. The cat riot doesn't transfer very well as it is. If ski pressure can't be obtained by front track shock without going full preload on the shock then try c&a skis and good 7.5 shaper bars
You heading to ERX motor park in Elk River this weekend for the debut of the 23’s?? I’ll be there checking them out!!
I have other obligations and can’t make it, hope it’s a good time!
The skis definitely do have adjustable weight points on the ground..
The problem with so much center suspension pressures are higher track approach angle along with reduced top speed, higher frictional losses and increased hi - fax wear reduced gas mileage.. and a higher center of gravity.
Excellent points and I agree completely. In suspension tuning, there's always a balance. Thank you for commenting!
I'd think that's a huge adjustment ! I think I'd have adjusted ski spring preload, front rear spring preload, and rear rear spring preload. Small adjustments on each
8:02 Are the ice scratchers on your Riot OEM? How do you like them?
They're OEM, the Riot gets scratchers from the factory. They don't last forever, I think I got about 2,000 miles on my first set. However, they do the job and I'll keep using them on the Riot. Not sure what I'm going to put on the catalyst yet.
With this fit, don't go on a bumpy trail, you'll break your back. Basic adjustment should be with your butt sitting on the sled...don't look at your suspension that way. Good development.
I think your point is important. To clarify, are you saying that sag and initial configuration should be set up with the rider seated on the sled before modifying the suspension. Is that correct? This is something I didn't include in the video, but is important. Thank you for commenting.
@@ponycarfan Arctic Cat's choice of springs causes a great deal of inconvenience and concern for comfort and performance. The proposed set-up is far from perfect. My Arctic Cat no longer has any original springs....More comfortable and faster, but still far from a skidoo R-Motion.
Make sure to hit some bumps for testing not just smooth. You will buck off the seat if you crank it up too much.
Great advice! Thanks for mentioning that!
On my 2023 riot 9000 I find in the turns I loose grip in the skis and want to go wide. Little history I have a 3 gallon gas can on the back I’m 250 plus a full back pack. Just wondering what I should do?
Do you have EPS? I rode one recently and noticed understeer, but also noticed that the EPS worked so good, I was turning sharper than normal, which probably caused a little bit of it. Probably, though, it’s a combination of engine weight, the sled’s loaded weight and the length of the track. I would recommend the exact opposite of what I did, to put more pressure on the skis. Instead of letting out the limiter strap, try tightening it one hole. If the front end tends to dive or roll in the corners, then increase preload of the front shocks. Try 2 or 3 turns at a time - seems line 1 turn doesn’t change much. That will help turning, because it keeps the sled from diving and resists roll.

It’s has EPS and Atac. I was think the same thing for adjustments. And I was going to set my driver1 option to firm on the skis and medium on the skid
@@dallasleduc7700 I think that’s a good idea.
You spoke of turning the spring on that front shock. I didn't understand if you were tightening the spring to the right or were you loosening it to the left to get your preferred results. It was not clear in the video which direction you ended up going.
Good question! Tightening the front spring preload puts more pressure on the front of the track and takes pressure off the skis.
The trade off is that as the skis get lighter, they lose their grip. I found a spot where if I tightened it up more, the skis would get too light. It's a balance.
You can also lose a bit of ride quality. Expect to hit bumps harder if you get too aggressive in tightening the front spring. However, I think with the Riot you'll notice ski pressure before then - ride quality is fine for me.
Always tighten to achieve more pressure.
Front track shock.
A) The more spring tension you add to the front track shock the less weight over the skis and the less bite and less steering effort which can cause what is referred to as pushing in the corner. It will also cause the sled to transfer more weight and lift the skis easier.
B) The less spring tension you put in the front track shock the more pressure the skis will have on the ground also causing heavy steering and less weight transfer during acceleration.
@@Deerlover75 Thank you, that's a very clear way to explain it.
@@scottfurlong5475more pressure on the track or the skiis?
Did you tighten or loosen?
Good question. I tightened the spring tension by quite a bit.
There's a little more room left, but not much (maybe a quarter of an inch of threads). I'll probably go a few more turns before next season, but I could feel a bit more understeer after my last adjustment and wouldn't want to go too much farther.
This was my question as well. The video was great. Adding this one specific about the direction you turned it to make the steering lighter or heavier was the last piece for me.
More preload skis and front rear skid, Less preload in rear
Making it simple, well said!
