repair nytro subframe?

Lay a 2" x 4" \6" across the front of both spindles. Take another and place it vertical on the ski on the side that's bent. Take a piece of nylon webbing or strap and wrap it around the back and bottom of the spindle under the horizontal 2"x6" and around the veritcal board. Use the vertical board as a lever and it will bend right back in place.
 
***UPDATE***
Anyone who thinks they will fall into the "not abused, but bent" category shoot me a PM. I will give you contact info for a dealer that WILL HELP YOU!

As a matter of fact, if it's bent - regardless - let me know. We'll see what we can do.

So I attempted to straiten my front end. After doing allot of measuring I realized that my lower right a-arm was pushed back 1 1/4". Both my upper a-arms were in the same position, so just the lower portion of the sub frame was tweaked. I spent several hours with two straps and a come-along using the opposite pulling technique. After bending and rechecking the measurements several times I was finding my right upper a-arm was being bent backwards. So with a ratchet strap I tied the upper right a-arm to the upper left a-arm creating a triangle shape, with one more ratchet strap pulling my left upper a-arm back to the drop bracket. I was trying to counteract the backwards pulling force on the upper right arm. After a couple more tries with the come-along I wasn't getting the results I was looking for. The next day I attached a tow strap to my lower right arm and hooked the other end around a tree. My first attempt I half throttled it in reverse with no change in the measurements. My second and third time were progressively harder, with me getting whipped off on the third attempt. The forth time at pretty much as fast as you can get in 15ft, I was bucked into my fence 5 foot away. It's fixed now. The measurements are within an 1/8" on both sides. based on my experience I wouldn't recommend the technique with the two opposite pulling ropes, it puts too much force into the upper arm. My technique worked, but it's not the safest. I wish I had videoed it so people could see the kind of force necessary to bend it back. I bought my sled used and the closest yamaha sled dealer is 7 hours away, so I don't think I'll be getting a replacement one from yamaha. If my front end makes it through the season, I'll redesign the front end this summer or buy a diamond-s sub frame.

I believe I fall into the not abused, but bent club. I have no idea how it could have bent so easily considering the amount of force that was necessary to get it back into proper shape. But like I was saying I purchaser the sled used with 300 miles and don't have a yamaha sled retailer for 7 hours. If you know someone who will help me get a replacement I'm all ears. If I do get a new one, I'll be adding some more tubes to the frame, or maybe jig it and make a cromoly version.

I think I can join this club. Only lucky 13 miles on it. Bent all up today on christmas day.:( Is a new O8 MTX I bought in Minnesota last april, but I live in Saskatchewan, so it won't have any warrenty here anyway. Both right A-arms are bent, not sure about frame. Need to further look at it.

Funny thing is I read this thread a few days ago and also a few others about this very same thing. The ski just jarred back the right side instead of popping up out of a hole. The snow banks here are concrete hard from the strong winds latley. So no abuse here, but just a little bad luck.
 
Hopefully Yamaha fixes this issue. I'm sure they know about it.

oh they know about it and they have been fixing them you just have to have a dealer that will make a phone call. I talked to to RTA at yamaha 1 time and they told me as long as there is no other damage to just fix it. So thats what i have been doing.

Sounds like yours was the same as mine. If you've got it that close to straight now I'd weld on the braces before you ride it cause it'll bend again for sure.

I have an 08 Nytro MTX with 69 miles on it. I live in Portland, Or. Went riding on it for the first time this christmas weekend and was told that i bent the front subframe. The dealer I bought it from told me that Yamaha would pay 1/3 if I and the dealer would pay 1/3. The dealer told me he would not pay for it because he believes it is a Yamaha problem, not a dealer problem. Any help would be great. It was not a hard hit at all, but the right ski is knocked back about 3" and the shock is against the upper control arm.
