2008 Nytro Suspension bottoming out

[pro_stock_1000]

I got a 2008 nytro mtx that as been stretched to 162. I have a timbersled rear suspension with fox shocks. I'm having trouble with the suspension bottoming out often and my shocks are at 150psi which is the max I can go.

I often also ride 2.

Any suggestions on how to stiffening that rear suspension. Even in rough terrain, I can bottom that suspension when alone. I weight 200 pounds.
Can it be the geometry of the timbersled which is the problem, or the fox shock? I tought for sure I had a perfect settup until I tried it......Really not satisfied.
Is it normal?

Any suggestion would be appreciated.

Thanks

How long have you had it? Shocks may need to be rebuilt. I ride with 90 in the front shock and 125 in the rear shock and have never bottomed out. I am 220lbs

I just bought the sled, so I don't know when the shocks where last rebuild.

If the shock hold there PSI, shouldn't it be good, or could they still need rebuilt?

Do you have a timbersled suspension or stock? Are you also 162?

thanks

It sounds like something is going on. I have a 08 N/A nytro stretched to 162 i am 250 lbs with gear and dont have an issue. I also dont launch myelf off cliffs either. However with that being said I did have my shock revalved when i bought the mountain tamer kit because i was over the range of the stock Float as far as weight.

Stupid question first - you are putting air in the shock with the rear skid in the air right and not with the skid on the ground? I had to ask =)

Two things i would look at. One if the shock was revalved before you had it for a lighter rider even if it held PSI there still could be in issue. I would have someone look at the shocks and have them revalved regardless if you are having issues. I know allen at timberseld is able to do that or take them to another good shop in your area. I would also call and Talk with Allen and Timbersled. He has great customer service and is always willing to help out dialing in his suspension kits. Also i think it was either 09 or 10 Allen started to offer a update kit for the mountain tamer kits that relocated the rear shocks a little to stiffen up the suspension if you where having issues with bottoming out. I would ask him about that.

Do you have stock rails or aftermarket rails? look to see if you have two holes located on the rails where the center shock is mounted to the rail. If there are and it is located in the rear hole move it up to the front hole. it only moves it up about an inch but that will decrease the leverage on the front shock that will in turn stiffen it up.

Good luck

If it's a first generation timbersled skid using the Yamaha rails with an extension from 153 to 162" mine was the same way. You can go to 175psi safely on the rear, but no more. The shock won't blow, but the dampening gets upset. I had my rear shock revalved at Carver Performance in Thief River Falls, MN. That was where Allen at Timbersleds told me to send it to. Once that was done 135psi was adequate. I weighed 220 fully geared on that setup.

I had originally asked the question as to when they should be rebuilt. The answer was if the suspension started to bottom out. Like the above metioned the valving may be in correct.

I do have the timbersled in mine but it is a 153. I run mine they way I do because I want more weight transfer.

Thanks guys.

I will call Allen at timbersled for that upgrade if any.

And I think I will get those shocks rebuilt to make sure.


Thanks

I have a 174 with Ice Age rails and the upgraded old Timbersled suspension running Fox Floats and it's too soft for me as well. I had the shocks re-valved and re-built but still too soft. Now I am a 275lb linebacker-sized rider, AND I carry 4 gallons of fuel on the back, so I am testing it for sure. Anyways....after some conversation with T-sled, I am going to put a Z-Bros X1 shock on the rear. We will see how this works out.

Let me know if that works out for you.
