Nytro Bent Front End this one has hit nothing WITH PICTURES

IF Yamaha has found an issue with the front ends, why no immediate gratification for info and immediate fixes?????????????

IF they are finding something it is right now or at least recent. They wont likely announce much of anything if anything at all until they have sorted it out and maybe not until they have a fix in place.

Guess what? that takes engineering, likely testing of prototype parts, figuring if it is just certain serial numbers or all etc etc which all takes time!

I do not know if this is a flaw, or what Yamaha is up to....
just tellin it like it is........
 

The problem with the spindles being at different angles and the shocks not right up the middle has nothing to do with the front frame. Its the upper A arm that is bending if you hit somthing with your ski or carbide. The upper A arm is bending forward during one of these hits. A freind of mine hit a guardrail with his right ski and it stopped him dead in his tracks. When we looked at it the right spindle was more upright than the other and the shock was closer to the back of the A frame and not up the middle. We took out his shock and with a large pipe and some protection against the A arms we bent the upper A arm back to its original form. This took some hard cranking on the arm but when we were done everything was back to normal and looked perfect. What is happening is with a carbide hit or a very low ski hit the spindle will pivot on the lower A arm and bend the upper arm forward. I don't think the upper arms a made to withstand any kind of hit in that direction. I'm sure Yamaha has figured this out and is going to come up with something. Also this isn't anything new, I have seen some Revs suffer the same kind of damage from this type of hit.

This could be, or maybe you're just bending the sub frame mount back into a closer normal state where it was. People have purchased brand new a-arms and still have the same problem.
 
Ya, it was not the a-arm on my friends sled, it is the top a-arm mount that is bent forward from the looks of it. I think if he took a big friggen hammer and hit the a-arm it would go back but he doesn't want to risk weakening it more.
 
I had my sled at the dealer today for a oil change and to inspect the spindle angles. They said YEP they are different, but could not tell what was bent or why my left ski ( clutch side) sits 1/2 inch further back than the right side, just that it did. He spent a hour measuring and could not find anything. Tomorow there will be someone from Yamaha's product development there, hopefully he will know where these things are bending.

Has anyone with a small difference in the spindles found where they bend? and are they bending again if you straigten it by simply bending it back?
 
I bent mine back with pipe a arms are stronger than sub frame just tweeked subframe back spartan thought that what was he bent replaced a arms and did not solve problem till replaced subframe

Exactly what I've been saying. The a-arms, especially the lower is way stronger than the subframe.

GT44....That product development guy you speak of is the same guy who introduces the Nytro MTX in the promo DVD that came out last year. The blonde guy. He was at our dealer yesterday and I recognized him as soon as I saw him.
 
bent front end

I don't have a fx nytro yet but i guess its a good thing that they don't go 120mph If I cant trust the front end going threw the woods on a fast trail I dont want the sled. I hope the spindles will be stronger for 09, I always thought they looked weak. I have a 05 revx that I have hit every kind of mogel imaginable and it hasnt bent the nun ( subframe ) butI also installed the 440 stiffineers from day one. I have 7700mi on it now with one top end and other naging problems starting to accumulate I miss the 2000 srx I had with over 12000mi and never touched the engine. I also have a 06 apex gt it had engine probles at 1700 mi (cam gear bolts backed out) I just want a sled I can ride for 15000mi that is powerfull, fast, comfortable, light and can take mogels and not bend or fall apart. please yamaha am I asking to much.
 
Goddo not sure if that was him or not. I had no intentions of talking to him, the dealer was going to talk to him about it. They had pics and all the measurements he needed to explain the situations. I had 300km of riding to do today, I wasn't waiting around. Bent or not that is a amazing sled, still very pleased with it.
 
TurboJamie did the correct thing and took it to his dealer, where they came to a conclusion on fixing HIS sled. If you have a problem, bring it to your dealer for evaluation......PLEASE!!!!! Yamaha probably and does watch the site, but what do they know you by, your member name? They need all the information, and need to see the sled, biotching on the site will not fix your sled, you NEEEEEEEEED to bring in in to your dealer. I can't say this enough.

As far as my Nytro, I have tried to kill this thing on jumps and holes, (everybody that rides with me know how I play) but haven't seen any movement on parts.....Yet.

Here is another thought on MY sled...... Since I had mine totally dismantled to paint all my parts, I like to check all bolts. Everything moved just a little bit, but thought that was just my feel of making sure things are tight.

The guys that have thier sled arms tweaked, have you tried to bend back? I would like to hear of how easy the movement would be to bring it back into or close to factory specs. If it bends that easy, it should straighten easily also. This way we will know what is bending.
 
I did straighten mine, while waiting for our agreement to go though. So far it has not moved back in 300 miles.
 
rode up around hayward wi this weekend and pounded the hell out of it going to flowage and the front end is still alright. MY rear end though was sitting on the snowflap, so either my springs are junk or the shock, but the shockes don't hold the sled up. 3 other nytros in group and mine was the only one doing this.
 
Is it the chassis or the A-arms. I know I have tweaked a few a-arms on my ZRT, but never bent the chassis
