2 stroke vs 4 stroke?

[mountain74]

I am going to be buying a new sled this summer with the intentions that it will have a turbo on it sometime next winter. I had my mind set on a Polaris Dragon 163 but after seeing that new Yamaha Nytro its starting to grow on me.

So my question is what are the pros and cons for the Nytro and Dragon? Is the weight of the Nytro going to be bad for side hilling and playing in the trees? Is the Nytro going to last a lot longer before a rebuild? Will the Nytro be a turn key sled that i don't have to be tuning all the time?

Just any general information about turbo'd Nytro would be great as i have not done any research on them yet.

Thanks....

Don't waste your time and money on a two stroke turbo go four stroke. They last about 50 times longer and make more power less money for gas and on and on!

boosted 4s vs boosted 2s reliability...
4s no doubt.

obviously the 4s looses the wt game; but for the most part, if your not stuck, the wt issue isn't overly noticable.
at the end of the day i may be a bit more tired or wore out, but reguardless I have a helluva lot of fun and i am essentially riding a lot harder...and, it does get me in better shape. haha

depending on the turbo, will determine weather there is any tuning req or not.. mcx is prob the most noob friendly; install, turn key and go.
however, for the most part, my impulse kit has been reletively 'set it and forget it'..
of course i'm a tweaker and don't mind learning what things do..and like to 'dial things in' and so on...so, the impulse kit actually "fits" me better in that aspect. with the MCX you have none of that, so while its what makes the mcx better, its also what makes it worse.



coming off of a 840HO Rev, i can say i had a lot of fun w/ that sled too...but I'm still happy with my decision to move to the boosted Nytro. W/o boost or the diet, I can honestly say I prob wouldn't be quite as happy..

4 stroke all the way. If your interested in a supercharger let me know i can take care of you, Thanks Skyler 888-649-4609

Agree--The nytro will be alot less headache. You can still throw it around and go play in the trees. Reliability is the biggest factor tho. It will last lots longer.

 

[modsledr]

If I were you (and this time last year, I was) take a look at all the used sleds for sale. GREAT deals to be had right now, and way more sled for the money. You can save at least 10k.

If you decide to go Nytro, you'll need more than boost. At a minimum, the rear skid needs to be replaced (timbersled, m-10, ez ryde, etc...)whatever suites your riding style.

And once you ride one with an aftermarket tunnel, you'll want that also (plus that moves the cooler to the rear and opens up the undehood area for more airflow to the IC.

With the Dragon, there are also some great deals out there, although with the HMS turbo now making it to the snow, I would wait for one of those.

Dragon needs some rear skid work as well, but not the whole thing. Front can be improved with shocks, although the z-bros front is sweet!

Where do you do most of your riding? What type of riding usually?

 

[mountain74]

I live in Calgary Alberta. So i do most of my riding in Revelstoke, Golden, Valemont and McBride. I do some hill climbing but most of my time is spent in the trees or out boonedocking.

The reason that i was thinking about going with the dragon over the Nytro in the first place is that i have a friend that builds kits with meth injection and all the good stuff and promised me that it would be a turn key sled like a Yamaha turbo but lightweight like a 2 stroke.

 

[SLY]

IMO the meth kit will drive the reliability way down. I think there will start to be lot's of engine failures as more people rely on this for deto control. Just run the octane needed, it will cause less grief. Been there.....

I ride a Tnytro and 2 of my riding buddies ride turboed 2-strokes.
No doubt the nytro is a heavier sled; however, it is very well balanced and handles exceptionally well. I can play around in medows and trees, and have just as much fun. If I get stuck...yes you notice the sled is heavier.

A 2s naturally doens't last as long as a 4s...boosted or not. In general we will rebuild the top end of a 2s every 1500 to 2000 miles. Over time the skirts wear down and become week. the compression is usually fine, but comparing the piston skirts with a micrometer, you can see the wear and obviously it weakens them. This is cheap insurance since a top end can be done for close to $500 or $600, and doens't take that long for a 2s. I have heard guys running a boosted 4s and have over 6000 miles with no engine work. with having said that if something does go wrong it often coasts much much more.

When running a boosted 2s, the life of read pedals drops drastically. Most of my experience is with a TM8, and they do break. Since this is known to happen have these with you at all times if you go that route.

As a general note, I think both turboed 2 and 4 stroke kits are well designed and the tuning is getting much easier since lots of time has been spent on these kits. I have found the OVS turbo kit to work great for 2s and tunes just as good as my Nytro...but as mentioned the MCX is probably the one turbo kit that takes the least amount of tinkering.

Cheers.

I beleive the 2010 nytro 162 will be a perfect sled with boost. the chasis is built to handle stock performance and with boost you can control the amount of rear transfer with air or add some coupling blocks in the pre-drilled rails.
think i should get one.

[deboer]

I would go with the Dragon 163 cause if you put a boondockers turbo on it the thing will climb like noboddy else also Polaris will have most of the kinks out of the Dragons next year and with a boondockers on it you will be pushing about 225 to 250 hp

 

[iluv2fly]

I have a new 09 M8 and I love it but if I go turbo it will be on a nytro. They have better reliability by far and with lightweight mods you can get the weight down a lot.

I'm thinking the same thing ,10' nytro is what i want out of a sled from the factory. maybe i wont mess with it right away!

 

[mountain74]

Cool im leaning towards the Nytro now from all the good info....Thanks for all the reply everyone keeps pushing me more towards Yamaha !!

what are they changing for 2010? i heard just colors

 

[turboless terry]

I have a turboed nytro and am thinking about a turboed cat. I know it won"t be as reliable. The nytro is as trouble free of a sled as I ever had. The power is awesome. The weight sucks. If you are on a hill or in the open you don't notice it. If you are in the trees the weight sucks. You will need an aftermarket suspension. Ididn't want to throw anymore money at mine if I am going to get rid of it. They are just not an all around sled to me. Usually I would say if you are going to run a turbo you need a spare sled but not with the nytro. It all depends on your riding you are going to do.

 

[absoluteapex]

if you have your mind set on the draggon then get it,there can be 16 pages of this shet but you will still get the polaris,turbo it and ride it,why ask about the nytro

It's funny how people get offended if you don't want what they want. It would suck if everone rode the same thing. That is half the fun talking trash to your buddies.

The TNytro is in a different league than the 2 stroke turbo's in power and reliability. I have had and built quite a few 4 stroke turbo's. The MCX turbo is awesome IMO because all the sled owner ever needs to do is adjust his secondary to suit riding conditions, it's a real gas and go setup. The Apex turbos have been very good but the new Nytro is a different animal and is a lot more responsive in the power and handling departments.
