Fx Nytro RTX VS XP XRS 800

[sleddingfarmer]

yeah I forgot to include oil, spend the time buy and change the oil in the 4 stroke or just buy the oil and dump it in the 2 stroke. And the e-tec gets pretty good oil mileage...I consider it even, with the slight advantage going to the 2 stroke e-tec, just because its easier to dump it in than it is to change it.

I got 1500 miles on my hyfax this year, they were just about wore through (I poked my finger through them!). But I spent the money and got 135mm wheels too.

And I am selling my nytro, to my brother, I think it will be the perfect sled for him. I just didn't match up with it as well as I hoped.

Anybody check the Dootalk website?

Just for fun I checked dootalk to see what they are saying/asking about the XP sleds. Seems like they have plenty of their own issues and problems. Examples: hole in piston with only 675miles on sled; Can't clean the powervalves yourself on e-tec; front heat exchanger falling off; bolt shearing off and destroying clutch; oil pump cable fraying; special tether/key not letting sled run; front suspension bushings cracked; and on it goes.

So I think whatever sled you buy there is going to be some issues. You will be able to find someone that has had great success with brand-X and someone else that has had nothing but trouble with brand-X.

Your best bet is to demo ride some sleds and see which model suits you the best. Snowmobiles are ridden in a tough environment, so they are going to require more love. Everybody has their own opinion, so don't go by what others say. You know your riding style.

Just my two-cents.

Not a chance going back to the two strokes. Had them all my life and if you dooooo, welcome to the digestion of a cylinder and crank problems. See how the 800 e-tech holds up, but how many sleds can you hold WOT and not break. Nytro and Apex motors rock!! Good luck!

Thank god for 135mm wheels! Test rode a500 snopro last week. If they put an 800 ho motor in that chassis, nothing will catch it. Getting too old for that chassis,will leave it to the young bucks. Wouldn't swap my Nytro for one. I know its not fair to compare a 500 2stroke to a Nytro, but my sled felt like a Ferrari in comparison.

it makes no sense to me why cat didn't at least put a 600 in that sno pro chassis along with the 500.

Check out this webiste, these would be some fun sleds www.track2trail.net

Yea,I just don't know what to do. I think it might be in my best interest to work with hygear get this sled to rock even more. Fix the joints and add a clutch kit

This is my summer project then I think the sled will be sick. Its good now with what I have done but it needs that little bit more.

And believe me, almost everybody ends up dumping $2K into their sleds now. No matter what the brand. Both my buddies with Poos have dumoed that much into their 09 and 2010 Poos.

See how the 800 e-tech holds up, but how many sleds can you hold WOT and not break.

I agree. Did several lake runs with my buddies. One has a 600 Etec and the other has a Poo 800R. Every run, those guys either let off after 1/2 mile or they had their temp light come on as soon as we got off the lake.

They guy with the 10 800R had 350 miles on his and a few times it started to puke out on him when he held the throttle full on. I can remember thinking, I had never been on something that would take that many wide open runs for that long on my Nytro.

While I think my 4stroke Doo is a near perfect sled, let's face it....there are times when these 4strokes feel a bit heavy. An 800etech would be very tempting as you'd nearly have the best of both worlds.

You'd be at least 7,000-8,000 miles into the 2 stroke before you started to get a little nervous about needing a top end. Up to that point, it appears guys are having just as many issues and sticking just as much money into Yam 4 strokes as guys are spending on Doo 2 strokes, so they'd be wash for a couple of season anyway.

Like I said, I absolutely love my 4 stroke and it has far exceeded my expectations. But, that 800etech sure makes a guy think a little.

The etecs suffer the same fate as the carbed 800r does. Crankshaft failure is almost a given due to the fact that rotax uses isoflex greased bearings for pto and mag side. Seal failure can occur as soon as 1000 miles and slowly start to seep out the isoflex. Then crank failure will occur. Some have had good luck with 800r cranks but overall they dont last very long. The etec engine uses the same crank design. The etec will have a very precise fuel delivery which will help with top end life but one bad tank of gas and kaboom! I always told myself if I ever wanted a 2 stroke again I would install an egt gauge so when you get that warning lights you know somethings wrong and save the top end from a burn down. Bad gas, base gasket, crank seals, leaking carb boots or carb problems, faulty injectors etc will all raise egts to a dangerous point. The warning light on the gauges will alert you of a problem and may help prevent scraping a cylinder and piston. Next problem is diagnosing whats wrong. nice sled though, just hate having to worry about octane and gas quality with a 2-stroke.

There's good, bad, & ugly with every sled out there. The million dollar question to ask yourself is, "what do you want in a sled?" bells & whistles, top end, reliability, torque, trail performance, racing performance, off trail performance, and so on and so on...It's that simple IMO

 

[canuk77]

Well i have 2 skidoo's in my garage and 1 is for sale right so i can replace it with a phazer.I want something that is relaible and durable.Im a die hard skidoo fan but not impressed with the ever troublesome new technology and really bad service and prices...I just want a sled that i can go out,get on and ride.My friends have nytro's and they are glad they got rid of their doo's.

Depends on how many miles you do per year.

800r or etec motor is only good for 4000-6000 miles before it needs a overhaul. any more and your asking for trouble.

XP chassis does not stand up to abuse as well as the Nytro, now some will tell you that the nytro bulkhead is weak. And that may be true. But near everything on the xp is weak.

As far as performance goes the XP will take the Nytro overall but your getting a sled that you shouldn't expect to keep for more then a year or two without problems. The Nytro will as a whole last longer. They both need standard maintenance tho.

I love my nytro and expect to get 4-5 hard years outa it. I do 2-4000 miles per year.

I'm in my 3rd year now and unless I fall into some money expect two more years outta it. When I was buying doo's 600/800, I didn't even expect to make it through year two without issue's. As I knew better.

You being the expert you are on both sleds but you only own a Nytro correct? I have an 09 XP 800r X sled and an 08 Nytro and from a durability stand point the XP is a better sled. The XP has never broke down on the trail and has only been to the dealer once for some new hose clamps to stop the slow antifreeze drips. I can go 120+ miles on a tank of gas in the XP where the Nytro can rarely touch a 100 miles on a tank in stock form. My Nytro has been in for ball joints, had the A-Arm bushing replaced by me, exhaust split wide open at the collector due to poor welds and goes through hyfax pretty fast. And now due to a design flaw on Yamaha's part my Nytro is at the dealer in a million pieces because the oil filter got cut open from a bar rubbing through it and will most likely be totaled because Yamaha doesn't sell a complete motor or even a crate motor so to piece a new motor together it's more than $6000.00 in just parts. So you tell me which sled is more durable?

You were the guy who blew the Nytro motor right? You seem too have left out that you have/had a Turbo on it

 

[sleddingfarmer]

I believe he had a supercharger on it. But that has nothing to do with why it blew up. The alulminum rods in the stock bellypan wore a hole in his oil filter. I recommend that everyone take there belly pan off and do something to prevent this. I took mine off just to check, and it had wore the paint off my oil filter.

Sold my nytro to my bro yesterday, ordering a new ski-doo asap.

It had an MPI Stage 1 SC on it but that didn't cause any of things I listed to fail. The things I listed are things that are failing on stock sleds so I don't see how the SC would cause any of those failures do you?

Posted a more detailed comment on another post but a buddy of mine has 2 new E-Tech's. First trip out, 1 wiped out the secondary clutch and jackshaft. 3 weeks later, parts are still on backorder. He bought an '09 Nytro FX for a spare. He took that and the 1 good E-Tech to Canada last week. Decided to "compare" the 2. The Nytro ate the Doo up and spit it out 4 times, 2 rolling, 2 from a stop. He also said the Nytro handled better that the Doo. We are talking a 1200 mile trip in 5 days. Only thing he didn't like was the small tank. He is getting a 10 gallon tank installed this weekend. I considered this report accurate as the same guy owns both. Personally, I've owned both myself and I prefer the heavier Yamaha for long range riding, more comfort. Like comparing the ride of a Mustang to the ride of a Lincoln. All sleds need to be set up for your own personal tastes.
