2009 XTX suspension "tuning"

[Ruff_Rider]

So I bought my first Nytro this fall and finally took it out on the first trip. 300 miles later, I noticed that it takes some "effort" to turn...as I have read all over these forums. I can't really stick any more cash into it this season. I am looking for some tips on adjusting my shocks. This sled is also my first with the clickers.

I believe that I need to put more pressure on the center shock by compressing the spring. So should I soften the preload on the front shocks as well? I was also told loosen up the limiter straps. Do I leave the clickers alone? I am just feeling a little overwhelmed as this is new to me. My old VMAX was simply sit down, mash the throttle, and lean...not so much anymore.

Put the front end up on a jack with skis dangling. Loosen the front coil springs until they have no tension. (Free play) then snug coil spring collar. I always start full soft on compression and add in a click at a time as needed. Depending how rough trails are. Keep it from bottoming. This trick will also keep sled from high siding through turns. A.k.a 1 ski in the air. Letting limiter out just puts more track on the ground making the front end feel lighter. Trade off is under acceleration the front end wants to lift. Just adjust your riding style come fast into a turn glide through and accell out of turn. Also you can play with transfer setting and limiter combo to fine tune

X2 on Pedros83 tips!

OK...I will start with fully softening the preload on the front springs. Too bad I won't be able to try this out before my trip. I will leave compression and rebound where they are at. If I start to bottom out the shocks, should I tighten up the springs or change my compression? Should I tighten the rear spring as well, or leave it?

Yes just add compression on the front shocks if you find its bottoming. If you tighten center spring you will lighten steering

I think this is one of the biggest misconceptions in snowmobiling. Spring preload doesn't effect bottoming. The coil spring takes X amount of force to collapse. So regardless if you start with minimum preload or full preload, it still takes the same amount of force to collapse the spring.

So adjust the clickers to firm them up instead of the springs?

Do you mostly trail ride?

Do you mostly trail ride?

Yes, almost exclusively.

I would start like 3 clicks from full soft (all the way counter clockwise) and add 1 click at a time until you find your not bottoming out. Too stiff and it will ride rough in the stutter bumps

Did you adjust the preload on the front springs already?

Sounds like a plan...now how would I know if I need to adjust the rebound? Sorry for being a PITA...

No, not yet...no snow around here right now. Will tackle it sometime before my next trip in about ten days.

So, I logged just shy of 300 miles after softening the front preload and adding a little pressure to the track shock. It appears to have made a difference, so thanks for the suggestions so far...

The sled does turn, but its still heavier than I would like. I am debating what to change for next season, since I think the winter around here is done. I have been looking at the options from JRE, the new spindle kit and the track relocate. Can anyone say whether or not the spindle kit from JRE helps? Also a little nervous about the skid relocate as I run studs and don't really want to punch holes through the tunnel.

Any thoughts???
