Your suspension adjustments and results?

[logan1080]

Buddy convinced me to play with my suspension on my '13 pro rmk 155. So I softened up the springs on the skis and stiffened the front spring on the track and softened the rear spring on the track. It seems to be more flickable through the deep snow than it was before but I just rode it for the day. Not sure if it's all in my head.

Did the exact same adjustments on my 2014 155 Pro. The rear track spring was set a bit too stiff, the front track spring was a bit too loose, and the front shocks way too stiff as delivered when I picked it up. Made the same adjustments you did. Night and day difference on my last ride. I did tighten up the front track spring one more turn after my last ride but haven't had a chance to see how it feels.

Mine was set for a wieght class below mine, per the book. I tightened all of the springs to the 220 lb+ specs. I left the front springs dialed tight because I can bottom it fairly easily. I doubt the cast aluminum belly would appreciate too much of that.

Rides awesome, climbs up on the snow like nothing else. I like the factory reccomendations so far. I can not imagine taking all the pre-load off the fronts. It is plenty soft as is.

When boondocking, if you can get some weight transfer rearward, I does wonders for your ability to carve. With weight transfer to the back, the skis get out of the snow and the track is much skinnier and the sled will tip over very easy. I like to run a stiff front track spring and a soft rear spring.

I adjusted my Pro to X1's on all four shocks and the results are pure heavenly delight!

Sorry, I realize that is not what you were asking. I just feel that after two Pro's I'm convinced that the stock shocks are not for anyone over 170 riding even at an intermediate level.

Couldn't agree more. After a number of renditions the local guy that revalved my shocks made for a significant improvement. The ressys were probably not necessary but they don't hurt either.

With a stiff front tack shock and a soft rear track shock you will probably find that it won't get up on the snow quite as well and trench more than your use to. The front shock needs to compress in order to climb onto the snow.

Great point vida. That is the trade off you get. If you are trying to go straight up, my setup is not ideal. Every tine you improve one situation, you might be sacrificing another.

Is there a thread or page anywhere explaining a base point for what adjustments you make to your sled will most likely do? I have a pro rmk assault with the walker Evans reservoirs I'm 200lbs. Don't really know what adjustments to make for my riding and how adjusting the springs and clickers will affect my ride. I'm all mountain and boondockig and getting into a lot more jumping and drops

Softer FTS, proper preload on the RTS and you'll float easier

Stiffer FTS will trench, as PV said it needs to compress.

I have the Exits on my Pro set and never feel the need to touch them for any kind of riding. Shocks may be different but the tuning aspects for all 4 corners is still the same.

1) Rear Preload, MFR guide on stock RTS is 5, I sag 3.5", Resi @ 10 clicks from soft.
2) FTS 1/4 preload, meaning loosen it up completely and crank it down 1/4 inch. Resi @ 8 clicks from soft.
3)Front Shocks, IIRC I have about 2" preload. Resi @ 10 clicks from soft.

I have tried a few different setups and like this the most:

- Set rear track shock for your weight as per the owner's manual. It measures in spring length so just....measure the spring. If you find the suspension bottoms often, go a little tighter than spec.
- Set the front track shock with roughly 3/4" - 1" of threads showing. If you find it wheelies or trenches too much....it's too stiff. There is a nice balance point between a "skis planted" feeling and trenching....you just have to find it.
- Ski shocks are personal preference IMO...more to do with bump ride than off-trail handling. I run mine fairly stiff, but I am 210lbs so your mileage may vary.
