You mean the poll on the internet . . .? Ummm hummm. . . . that should be incredibly accurate. . . just cuz its on "duh innernet".
Would be nice if we could see who voted (like most polls). Betcha there are some of the "trolls" - that don't even ride a polaris 850, who voted for an engine failure
If I could vote for all the ( NON-SNOWEST ) 850's owners that I 100% know went down that pole would be ALOT different.
and then there are the guys that voted ( all good ) and then their sled failed they can't fix their vote without contacting a moderator.

The pole should have another box ( that you can post 3 leak down test numbers over 900 miles divided by 3...... Or 30 hours divided by 3 )
There will be a considerable amount of 850's that get put to summer storage with junk top-ends only because their owners were to lazy to lazy to order a leak down tester and do the procedure.
And there is one more 850 demon in the closet that Polaris has not considered.
And it's something that I did not include in any of my posts on the ( 850 gone down already ) thread.
Over time, The center crankshaft seals ( WILL ) start to leak a small percentage
And the oil will then seep thru the 2 center seals into either one cylinder or both until the center water pump cavity is reached the top edge of the bottom part of the seal.
What's the big deal you might ask...... A few things.
Imagine the sled sits thru summer in a black enclosed trailer ( north of 120 degrees in the hot sun ) inside that trailer.....think of the thickness of the injector oil at that temp.
1- if it's equal on both sides, the first time you pull the rope it will almost hydro-lock...... And almost bend a rod...... ( what it will do is, oil foul the plugs so will won't start ) and since it doesn't have case drains and if it had them you can't reach them anyways you will struggle to get it started with a box of new plugs.
2- if it favors one seal only......and all water pump shaft cavity oil goes to one side...... The first time you pull the rope ( or hit the electric start ) and the motor spins fast the oil can transfer ( if warm enough ) to the top of the motor and it will hydro-lock and bend the rod.
This is why no 2 stroke motor should be designed with a full center cavity ( that depends on a perfect seal ) from a seal that will most likely never seal 100% of the time.... Seals wear.... And they slowly start to seep.
And then not only did they create a cavity full of oil..... They fill it WAY past the top of the bearing just below the transfer case floor.
Just like they did on the 2018 600 & 800 Axys case..... Bad idea.
The number of hydro-locked motors we are seeing has just started to increase.
And most people have no clue what happened....... ( example ) you gave the sled what you think is a decent pull to start it and the handle gets ripped out of your hand..... ( Well ??? ) what just happened ?
Well maybe it just slipped...... Of it partially hydro locked and then next pull it goes and smokes like crazy for a awhile ( this was classic Polaris 900 Fusion ) and the 850 can do the same thing.
I was not going to mention any of this because I really didn't want Polaris to catch this until after the 2020 sleds were released...... ( just being a capitalist ) but I don't want to see the 2020 model to suffer from one last stupid over site.
I don't want to sound like a know it all...... But Polaris would never have caught this unless It was posted.
We have since figured out a super easy fix to this engineering mishap.
