XTX rear sag

[Sask Attak]

Is 5-6 inches of rear sag normal? When I get off my 2010 XTX with 0 miles, the rear doesn't spring back to max height. I understand there should be some "set in", but put some ice and snow on it and it will get worse. What is acceptable sag?

Only on Saskatchewan sleds...not here in Manitoba. Check suspension settings. a softer setting won,t rebound as much or as fast. Check owners manual.

Atleast we know Yamaha didn't do anything for it on there 2010 XTX. There's alot of topics about this on the 09 XTX. Several idea's on how to help this out. Heavier springs, torsion spring spacer from Hygear (they actually said that with there spacer that the stock springs are good for a rider up to 250lbs, a different adjusting block so you can set the tension even heavier. Lot of ideas...I went with the torsion spring spacers.

So Turk, what are your rear suspension settings then? Oh, and by the way, GO RIDERS!

Riders got lucky. Good training when u can run a 300 mile td in any direction! aAnyway i weigh about 255 & I can not bottom out my xtx with rear skid in hard position & i ride with revs all day long trying to dust me.

I had 4-6" before removing the ice collectors and adding hygear spacers. Now, about 1-2".

I too removed the tunnel protectors and added the spacers and it has 1-2 inches of sag when I sit on it. I weigh 220 lbs and have the tortion springs set on hard (high). When my wife sits on my sled it doesnt even move...lol.

I would not worry about sag or "set in" without rider. This number is easily affected by all kinds of strange but meaningless linkage ratios when the suspension is extended and by shock absorbers containing return springs. Also, this number means nothing for the suspension performance during riding.
The number that counts is the sag or "set in" with rider. A good starting point is to put this at 1/3 of the total suspension stroke, making 2/3 of the stroke available for compression movements but also 1/3 of the stroke available for rebound movements.

how difficult is it to add the spacers?

For grins you might try adding some preload to the front skid spring. Many times if you do that you can back off your adjustment on the rear torsions - netting you a lot better ride with less squat. It's free to try too....

Anyone? Is this an easy install, or is it a real nightmare?

EASY CHEESY

It is easy cheesy - but that's not very descriptive.

I'll presume you have a decent understanding of how a wrench works:

* Rig up a way to lift and hold the rear of your sled.
* Undo the wheel assemblies that capture the front arms of the torsion springs.
* Take some load off the rear of the sled by lifting it a bit.
* Remove the bolts to the rear linkage (where the upper idlers are held).
* Lift the rear until the upper idler wheels clear the lower edge of the tunnel.
* Remove the bits from both sides that hold the torsion springs, stock spacer and idlers in place.
* Wipe off any schmutz and install the Hygear spacers with the counter-bore toward the skid linkage.
* Put all the bits (except the stock spacers) back on in the appropriate order.
* Lower the sled until you can line-up the linkage bolt holes with those in the tunnel.
* Torque the bolts into place (I use medium Loctite on these).
* Raise the sled a bit again and then reinstall the front wheel assemblies with the torsion springs. Make sure the rear arm of the torsion spring is engaged with the adjuster block and the block is set to low when you do this. It will take more grunting and swearing than before to get the torsion springs where they need to go.
* Torque the bolts tight on the front idlers.
* Lower the sled and you're good to go.

Note: this should take you about 3-minutes. Some details were omitted for brevity and to create more of a challenge.

Very easy...just did mine on Sunday. A lot less sag now.
