I have a friend that swears by four stroke Yamaha's. He says that he's ridden 2-stroke Ski Doo's and would never go back to a 2-stroke after having his 4-stroke. We both ride in the mountains, and I've only ridden 2-strokes. He tells me that a 4-stroke is the only way to go in the mountains. Personally it seems that a 4-stroke wouldn be heavier than a 2-stoke and wouldn't be that great in the powder. That's just my opinion and like I said I haven't ever been on a 4-stroke sled. I'm curious what every ones opinion is on this. Thanks for the response

ive never ridden a 4stroke in the mountains. but have ridden 2 strokes on all terrains. only ridden a 4 stroke down here in the flatlands lol. and they are alot heavier personally id still ride my 2 before a 4 in the mountains for the difference in weight and power

The 4-strokes offer a lot of benefits and if the extra weight isn't a big problem, they do very well. The newer turbo sleds are real powerhouses, which makes the extra 80-100 lbs seem like a lot less. The manufacturers are working hard at reducing weight, which has helped the mountain sleds a lot. Still not for me, though. I'll stick with that two-stroke smoke

You dont have to worry about elavation changes with the 4 stroke it will be heavier though,,,2 stroke you have to jet for the elavation...I agree with your buddie about yammi motors are great but in my opnion the yammi suspension sucks..I wouldnt be afraid of the doo 1200 the guys I know with them luv em and the new 4 stroke cat has a proven motor too..suspension on the doo & cat superior compared to the yammi.....Good Luck & have fun in your quest for a new sled!

If your sled is EFI, you won't have jets to change, 2 or 4 stroke. If it has carbs, both types will benefit from jetting changes as temperature and elevation change.

I use a two stroke. Its a matter of opinion.

I will stick by my 2 strokes the 4 strokes just have to big of a weight disadvantage for my liking.

I'm not necessarily looking to buy a new sled, just curious on what everyone likes. Thanks for the responses so far. I do have a carb sled, and I ride anywhere from 4000 ft and up. I know the guy I got it from did the same. should I be worried about jetting? I am about 1000 ft higher at my house then where I got the sled. I had a EFI Arctic Cat and I honestly didn't like it. It seems like it didn't run near as well as some of the carb sleds that I rode with. Also my dad has a 91 Polaris EFI 500 that I use to ride a lot. One of the guys I rode with had the same sled only carbureted. Both seemed to be set up similarly but his always out run the EFI.

You cant really compare the early efi systems to the engines that have come out over the last two or three years these new semi direct and in doo's case direct inject 2 strokers are building huge power for their size. There isnt an 800cc sled being built today running under 160hp and the other upside to these engines is much better fuel economy and oil usage.

Due to the ever tightening epa standards carb's will be a thing of the past within the next couple of years and I for one will be just fine with that. Given the fact that my etec engines get both better hp numbers and fuel economy and I can ride at any altitude or in any tempature and not have to deal with making any adjustments its the only way to go for me.

The answer is pretty simple... if you both ride together - just swap sleds for an hour or so!!! Then you won't have to ask the opinion of a bunch of people who wouldn't touch a 4-stroke with a 10 foot pole.

Just make sure you get him to agree that if his 4-stroke gets stuck, HE HAS TO DIG IT OUT. Can't lose that way!!!

Amen to that one of our group rides a Z1 turbo when he buries that 750 pound monster it takes the whole group to get it out!!!

If we get enough snow 2 ride in this year and I get a chance to ride with him I'll do that. Then I'll let you know what I find out.

the most current mountain machines dont wiegh 750 lb's any more ! they really are bringing down the weight on them ........ that being said , there are pro's and cons to both , if your considering a four stroke , for starters i suggest your find one to rent or borrow , cause ..... they almost HAVE to be turbo charged or supercharged to even be in the same playing feild as a two stroke . that means with a few models you can tack on and additional 3500$ bucks to already 12 plus thou dollar machine !!
the other thing to consider is , a four stroke machine is more of a point and shoot type riding style , so if your going to try to snake through trees and what not , you might not want a 4 stroke ,cause thats not where they shine ! if you want to shoot up a giant hillside (straight up) thats about all the straight line climbers use (is a four stroke)
cause they can build the engines up to 300/400 hp (scary fast )

2 stroke... no explanation needed... LMAO

Sure you can throw 500HP on a 4-stroke, but what are you going to do with that???

i like Power to weight. 2 stroke gets it every time

AMEN!!!! I wouldn't even think about a 4 stroke. My own opinion, but as long as they build 2 strokes, I'll buy. When all they have to offer is 4 strokes then I will be buying used and keep them running for as long as I can. I know the "Push" is there to get away from 2 stroke, but I'll push back as long as i can.

You just gotta luv those 2 strokes!!

Snowweasel

The first dirt bike I ever owned was an 04 RMZ250 4 stroke performance bike. I loved that bike more then I can explain. There is lots of power and you never need to be in the power band to access it. Ide like to bet it's the same on a sled. Sure you get the extra weight but the power is phenomenal. On the other hand all I have ever ridden is 2 cycle sleds and I wouldn't have it any other way.

A little late to the party but I have direct info.

There are benefits to a 4 stroke over a 2 stroke.
They live longer with less problems.
They are pretty much bullet proof.
Toss a turbo on them and they pull like a freight train.

that is the good news.
Now the bad news.
They are WAY heavier and you will feel it.
The older Apex's actually handled better than the Nytro.
I was looking at getting a 2013 Nytro with a turbo. 180 hp at 10k feet seemed like a good idea. Ended up riding both a boosted and non-boosted Nytro for half a day.
I haven't worked that hard to ride a sled in 12 years. I know you can make them work and work pretty good. All you have to do is change the entire front end, replace the running boards, track, exhaust and a long list of other stuff.

I ordered a 2013 Pro RMK.
