06 Nytro

[Snowbound98]

Picked up an 06 Nytro for my son with 1141 miles. I know I’m gonna need to replace the cam tensioner but I’d rather wait until after the season. Am I crazy? Should this be done now or is it more of a mileage thing? This low of miles it’s obviously been sitting more than ridden, is that just as bad?
I’m gonna throw some studs on, I already have them but my question is, I wanna run a single and double in each row but I’m thinking I might start with just installing the doubles to give me 96 but drill the holes for the singles so I can add them if needed to give me 144 total. Anyone see an issue with that or should I just do the 144 and be done with it?
Any input or feedback is greatly appreciated.

I've heard of them breaking at less than 1000 miles and there's 05-07's out there with 10,000 miles and never updated.

I looked at it this way when I had my '07 Vector. The failure rate is always 100% when it happens to yourself.

I'd do it now vs rolling the dice.

As far as the studs. 96 is actually enough. Yeah, maybe slightly understudded if you figure 1:1 horsepower rule, but 144 way overkill and adding unnecessary weight & rotating mass/weight.

You could do a 3/2 pattern, and that would put you right at 120 for the 1:1

Just know, it won't come out perfect. You'd have two bars back to back with either 3 or 2 studs at the end. Not enough to throw it out of balance, but it'll bother your OCD if that's a problem. Lol.

That's how my LTX Vectors are with a 3/2 pattern, giving 135 studs.

If it were me I'd do it also. (actually, that was me, I had a '06 nytro also and did it as soon as I found out)

It really isn't that bad of a job, takes a solid day in the garage if you take your time. Hardest part was grinding up a socket to fit the rear engine bolt.

That is a great find, if you are planning on keeping this machine the do the tensioner, it would just about drive me crazy wondering and worrying about it all season.

might want to service those shocks while you are at it as the nitrogen charge will most likely have leaked out. the fox floats on the front of those sleds are a love/hate depending on the rider. the sled i had them on was instant hate for me as they where both screwed when i got the sled with significantly more milage.

I know a guy that put over 5K on the same sled and never did the tensioner. If you picked it up cheap maybe roll the dice if you have some money involved then do the tensioner . Look up Catmans suspension setup and follow this to get it close . Keep skis and add semi aggressive Snowtrackers. Get some coil over shocks for the front . Most don’t like the Air shocks . This sled had the CK rear suspension. Hopefully someone can explain how to make it ride nice . I have no experience with your rear . 96 studs are plenty!
Nice find with that many miles . If it runs rough you might want to clean the carbs and Sync them . Your son is a like man !

Wasn’t expecting replies so quickly, I appreciate it.

I hear ya on rolling the dice. If my sleds were at my primary residence I wouldn’t even be considering waiting to do it. My sleds are in northern wisconsin and I’m just outside Iraq, I mean Chicago.
As far as picks, I think the 96 will be more than enough for what the sled is being used for. I agree the 144 is overkill. Maybe I won’t even drill for the singles. Thanks for the response.

I’m sure I could get it done in a weekend even if I’m up there to ride. I’m just not sure if I can get the part soon enough to have it for my next trip up. I guess I’m gonna try. Thanks.

I was hoping I would hear you guys tell me not to worry about this season and run it only because it IS gonna drive me crazy. I’ll keep this machine around for a while unless I start having issues with it and I’m wrenching more than riding.
Also, I got the sled for $3500 and the guy said it had 1826 miles on it. When I drove it into my garage I noticed the speedo in Km/H instead of MPH. When I changed the setting the miles changed to 1141. That was nice. Lol.

I’m not sure Steve is taking anymore shocks this year and he’s the only one I’ll use. But I thought the same thing but didn’t have time to take them off before I came home because I was too busy trying to get my Viper back together. Good thing is my son is skinny and doesn’t weigh but 110lbs so he’ll just have to deal with it. When I was his age I was on a 74 Puma so he can’t say nothing about rough riding. Lol. But I heard the same thing about them first gen floats. I’ll see what I can find. Appreciate ya.

I think it’s worth making the repair. With the low miles it has, he can use this for a while until he’s ready to buy his own. It actually runs great. I filled it up with fresh fuel, added some seafoam and if it stumbles or studders out on the trail, those carbs will have to come off. I thought the days of carbs were behind me but I couldn’t pass up this sled. I’ll check out Catman’s setup. I’m sure we can play with it a little but having the shocks done is gonna be huge too. I drooled over this sled back in 06 when it came out but never bought it. I think my son will do good on it and my other son got his snowmobile license so he’s taking over the SXR. This year should be interesting with both my boys riding with me. Thanks for chiming in.

Unfortunately, my suspension setup doesn't apply to the CK skid or Fox Floats. It's for coilover front & Mono rear.

I agree with the statement above about ditching the fronts in favor of coilovers. The 1st gen Floats are pieces of schit, to put it nicely. They are either rock hard making the sled extremely tippy, or flat resulting in little to no suspension travel. And don't hold a consistent charge. Get coilovers and set the preload to zero. If you happen to score some GYTR fronts, also set the preload to zero, and compression and rebound clickers fully open ( counterclockwise ) then 3 clicks back in on both.

I had an 06 RS Nytro ( my very 1st 4s ) and the best I could do with the fronts was 50-55 psi in them. That at least put the arms as close to parallel as possible.

The rear, well, just hafta see what works for his weight.

If you can’t find shocks I still have a pair of stock coil overs off my Vectors. They have about 2000 miles on them but are rebuildable and in good shape . For your son I’m willing to go cheap . I had an ad in the parts section if you want to look . Just let me know and we can work out a deal .

That may be something I’m interested in. I’m assuming they will fit the Nytro. Shoot me a price when you can, it may be easier to just swap them out rather than deal with these floats. Thanks.

 

[DGZRT]

That period of Nytro was the Vector chassis I would think they fit .

I looked up lower arms and they are the same so it should work. Message returned. Thanks.

well you can try my ck set up that mrsled pointed me in the right direction.

front skid shock, you want to loosen spring off so that it is stiff to turn by hand with the rear of the sled off of the ground. lock it down there. i always set the front suspension to almost parallel to the ground 1st before i mess with the rear.

set the torsion springs tension so that with your son on sled in riding position, the transfer is about 50/50. the shock does help with this a bit but it is sounding like for his 1st season it should be ok.

i would start with rear shock clicker at full soft and add a notch at a time until it quits bottoming with him riding it. have to adjust this again once shock gets rebuilt.

Thanks for the advise. I’ll try that.

@DGZRT- thanks again for getting these shocks out to me. My son said to say thanks too. I sandblasted the springs, adjusters and the tops of shocks and he painted everything. They will definitely get us through the season and then we’ll get them rebuilt. I appreciate it. The guys and gals here make this site the best! I hate to see the lack of traffic here because of all the social media BS, but this is my go to for all my info and ideas, I’m proud to be part of it. Thanks again.

I’ll get pictures installed and Jack on the sled when we get up north this weekend.
