True or False? Has Polaris updated the engine for 2013?

I am expecting delivery of a 2013 Pro RMK very soon! Quite nervous about it as i have never owned a Polaris but excited to buy American! Can anyone tell me if the engine specifications have changed for the 2013 model year? Some say the pistons have changed to address reliability concerns. Have they address horsepower? Does anyone really know? Thanks you! :usa2:
 
Heres my take. Every model year there are refinements and or out right changes. There are many threads about different part numbers which may or may not be because of an actual change or because a vendor is different. If you believe indy dan its a rod ratio problen. If your with pms its too loose of a piston causing issues. I get where your coming from but don't let it detract from enjoying your sled because of needless worrying. Even with the most reliable models there could be an issue. Hopefully you purchased from a good dealer,run good oil, let it warm up and don't let it overheat. You own IMO the best mountain sled out there, enjoy it and be amazed it the new levels it takes your riding!
 
word is, cylinders and case is different this year...same pistons/crank/head..with that said..make sure you burn 1 qt of oil for every tank of fuel..(most likely it will burn 1/2 that as deleivered) also every tank of fuel..add 1 pint of oil for every tank of fuel(right into the gas tank)..do those 2 things..plus warm it up every time to operating temp(110+ ) everytime before moving it(even when taking short breaks)..and more then likely..your sled will go a long long time with out issue....

Stewy,

thanks for the response! As you have probably gathered, I am new to Polaris. Familiar w Indy Dan but never met him. Spoke w him on this topic and said he did not know if there were engine updates or not. As a matter of fact, he said he doesn't believe anything until he gets inside of the engine. Dan recommends the following: Clutch updates, Air Intake Mods, Can....thats about it so far. I'll ride it. Evaluate it and go from there. The new sled is coming from a reputable dealer in St. Cloud (as far I know). Thanks again. BTW Have you had an opportunity to ride a Ski-Doo XM and Polaris?
 
AKSNOWRIDER,

Can the oil consumption be adjusted via the oil pump? It seems odd that Polaris has not addressed this.....Is it due to emissions?

Thanks!
 
there has been changes. exactly what and how much won't truly be known until the sled has been delivered. more power and reliability? that is the ultimate quest but can't be know for sure. from my "sources" the 13s were running with or out running the 12s with a pipe and can. take it for what it's worth.

yes the oil can be adjusted at the oil pump. and yes the reason the pumps tend to be turned down is due to emissions. although some cases can be blamed on poor dealer setup or at least a lack of checking. funny how in the beginning people were bragging about how little oil they were using and now everyone wants to know how to turn the pump up. the important thing to remember is it is still a two stroke. two strokes to not live without burning oil. doesn't matter how fancy the technology gets, you can't get around that fact. personally, i make sure my sled runs between 32 to 40:1 on heavy full throttle days (deep pow days) and i don't like to ever see much more than 55:1 even on trail/light throttle days. due to the progressive oil pump (usage is based on throttle position. it is pretty tuff to state an absolute ratio or amount of oil that needs to be used per gas tank. plus oil per gas tank tends to be a lot less precise and somewhat objective vs. an actual computed ratio.) as far as adding addition oil to the tank, i'm personally not sold on the idea. i don't think it will hurt anything but i'm not convinced it will make any significant improvement in longevity either. now, with the intention of full disclosure, i have a catastrophic motor failure at around 1800 miles +/- (required heli lift out of mountains) but i lost a cylinder skirt so extra oil wouldn't have help me. sloppy pistons are a known issue that has been discussed multiple times. hopefully some of those issues have been addressed with the current changes. but time will tell.

i had a chance to ride the new xm. i was very impressed with it. i've been riding polaris for a number of years and never liked the revs and hated the xp. thay handled like complete crap IMO. (the rev was a very nice upgrade from the more traditional trailing arm sleds with the introduction of the rider forward concept) the dragon was a far superior handling chassis to either one of those and the pro, amazingly, kills the dragon as far a chassis performance goes. the xm is a whole other story. four of us abused one for an entire day in deep, ideal snow conditions and were all impressed with it. (although a couple of the guys were die hard doo guys anyway) i could jump between the xm and my pro and do what i wanted with it. not so much with the 12 xp that was also there. do a search in the poo and doo sections and you will find my much more detailed review of it. (it is also entertaining to see the different responses to my praises and criticism in the different forums.:) )

enjoy your new sled.

Yes, the oil ratio from Polaris is to meet EPA requirements.
 
Sup piston skirts and cylinders are again thicker, also they are said to have offset the cylinder a touch to reduce loading on the thrust side.
But until I tear into one it's all a educated guess....have no worries its a good sled.
 
My dealer had a '13 for a few weeks and it ran 2 grams heavier weights. So that tells me the engine is making a few more horses. As long as the pre-production models aren't different than what you and I get.
 
I remember back in the day, Polaris got caught running "demos" at Arctic Man in AK with high compression heads to make up for the altitude. I rode a 600 they had there and could have sworn it was an 800, I had to look twice at the hood to be sure.
Not that that happens any more, but it just shows that nobody really knows what the new production sleds will have until they are delivered.
I am sure Polaris is addressing issues, I cannot see them liking paying for engines left and right.
Personally, I am going to run my 2013 until it kills it's first one, then sell the sled with a new engine and enough warranty left to cover one more failure for the next owner.
 
Heh, when the Doo 800 first came out, they made the pistons too small. We had to warranty (recall actually) a ton of them with new pistons, I used to bang out 4 swaps a day, hated it. But in all those swaps, I don't think I ever saw one that came apart. They were noisy as hell, you could hear the pistons just clacking around in the bores, it was horrible to listen to. I borrowed one of our demos and just couldn't believe the amount of noise the silly thing made at idle. And we used that demo for many miles before ever doing the update.
 
That pic is photo shopped. Should have put a Yeti in the background, would have been more realistic.

pv I like you review. I am fortunate enough to have both a Pro and XM on the way. I get heat from both sides but it seems the Poo guys actually take offense at any positive feed back about Doos. If the XM wasn't giving up 50lbs to the Pro it would be no contest. But it is, so there is a contest...

actually i found the doo guys to be more offended to have the slightest criticism of the xm (or any doo for that matter. just look at the response when you tell them how crappy the xp handles). but it is expected on both sides. people are naturally loyal to the brand the bought b/c they feel it is the best. otherwise they would have bought something else. plus they spent a butt load of their hard earned money on a specific item. no one likes to hear they wasted or didn't get the most out of/for their money.

or the poo could have 10 more horse and it would be a no contest, but it doesn't so there is. although it is a lot cheaper to add 10 horse than to loose 50 lbs... (ok, i'll admit, that was just stirring the pot! :) ) actually -50 lbs or +10 hp there would still be a contest and people buying both. all the sled are so close anymore buy the one you like and run it. well except for the cat. ( damn!t, there i go again! :) )

It true. The xp handles like dung! I know because I own one. The Rev chassis handled better. And weight does matter. Nice comment about return on your investment ....comparing 50 lbs vs 10 horsepower. My xp is modified with an narrow ski stance and a whole list of tweaks and adjustments to improve handling. Now it handles pretty well (and better than the 2012 xp). Few people will argue that the Polaris doesn't handle well. From my experience the Polaris also climbs well even with fewer ponies!

So....the way I see it (a die hard ski-Doo fan) is like this.....the Polaris handles great, climbs well, is FIFTY POUNDS LIGHER, costs less money and is made in my backyard. I bought a Polaris for the first time this year and hopefully somebody at Ski-Doo reads this post.

Did you get the part about FIFTY POUNDS?!!!!! Sorry Canada. Suck on that!:baby::baby:
