i was at dealer today. they said new bearing in ctr of crankshaft. has a retaining ring so its not walking in cases, covering oil port. also more or larger oil ports injecting oil into crank bearings...
With all of Polaris’s resources I would rather have a 2019 850 that was updated the way I see it rather then the way they see it need to be done.
They missed 2 of the most important dependability problems.����
Dan
So what are the two most important things that they missed?
Hmmmmm....
Well I guess I will say this..... ( it’s a know when to hold’em and know when to fold them type situation)
I posted pictures in detail months ago on this forum ( not sure if they were deleted or not ) they were on the ....... ** 850 already down ** thread
The early updates I posted have been tested all winter with no problems.
We made a few tweaks in the bottom end to increase bearing life from our early updates.
I am not going to post changes We made until Next fall.
I laid my opinion out on this motor months ago.... and posted detailed photos of what I did.
The revisions are all in our new Long Rod 850.... We will have a cut away of our Long Rod 850 on our website this spring.... ( some details will not be showed until fall )
The revisions will also be on our Mountain Warthog Long Rod 850 Turbo Motor
There will be several of our Mountain Warthog Long Rod 850 Turbo motors hitting the snow in the month of March.

So help me understand this, you revealed on the forum in the thread section another ‘850 gone down’ of the other two issues where you believe Polaris missed the boat with these 2020 updates. Now these two issues are topic secret after you mentioned them winter of ‘18-‘19?
I don’t own an 850 or plan to update both my 14s for a while. Just trying to understand your last comment.
I don’t see the long rod 850 engine on your website. Price? Does it make mo powa! Torque, especially in the middle?
What about cylinder finish, poor ring seal and obviously the mandatory leak down test. No mention of this from Polaris.Its not really a secret......... if you studied every thing i talked about and looked at all the pictures i posted.... Then looked everything polaris did the differences are for all to see.
I am not going to break it down to kindergarden level again.
I have a business to run.....and I have employees that depend on me to show a profit.
I gave out the the exact updates the 850 motor HAD TO HAVE in November/December ...to give long time piece of mind for dependability.
Since i did posted that info months ago ..... ( which as a whole is better then the full list of updates polaris did for 2020 ) I have since changed a few things that i feel are even better.
That being said I would be a moron to tip my hand before fall.
We have already emplemented these changes in february.
Indy Specialty has always been about trying to build a better mouse trap.
Pretty basic business plan.

Price? Any power increase on the N/A engine at all?
I
I wonder where ADDIE is ? AKA Kelsey with his big Facebook write up saying how I was wrong about every update I said the 850 needed.....
I wonder what the Facebookers have to say now ?
I went out on a limb...... and I put it all in writing.
I said time will show who is right or wrong.

Whatever 850's have the finish this one had won't make it thru the first season.
if they don't have a lock ring the crank will 100% of the time slde over and hit the case EVERYTIME
I feel sorry for anyone who tries to make this thing a 900..... it will go from 840 great to 900 garbage in a moment.

Closely watching the 911 BBDan, since you asked where I was at, I will gladly tell you..
I did quote a few of your "prophecies" above (in color), that have not surfaced in my area (and some others), at least.
1) The 850's around here have been almost perfect.. I know of 1 going down due to a stripped water pump gear. (nothing you mentioned in your list of faults)
My, personal 850 has suffered abuse like no other sled I have owned. It is flawless , so far. MANY others, in my group and surrounding area have been the same.. flawless.
2) My crank bearing has not moved (nobody else's around here has either that I know of).. Got close to a 1000 HARD mountain miles (ALL in deep powder held to the bar a good part of the day.. Over 1 minute WOT fully loaded pulls (more load than can possibly be applied unless in the mountains and deep snow ie.. no matter how long you hold it across a lake, it would not equal this kind of load).. So far, so good!
3) As for your claim about the big bore being a dog... The 911 big bore, we have created, is an absolute monster in terms of power and fun. It has been flogged in the deep snow as well and has proven to be very solid and reliable.
Should be a great option for most 850 owners. Pushing 200HP on pump gas is going to put a smile on most people's faces.
4) Nice work on the bearing retainer. Polaris made a mistake and have corrected it for 2020. I have insight that this was an error that should have never happened and was originally designed and tested with a "kept" bearing. When it went to production, this got deleted by mistake. Afterall, all of their previous engines have had a retainer. This is not new technology. Mistakes happen.
5) Speaking of mistakes, the extra case sealer falls into this category as well. Screen has been added to the check valve and sealant amounts are now well defined for 2020. So it should be good as well.
6)As for hone finish, We (and almost every other person who hones cylinders) will agree to disagree on this one. I still do not agree that the hone finish wears skirts. Nothing wrong with your super hone finish, just do not think it is required or increases piston life.
7) Single ring piston and power fade... I guess another agree to disagree with regards to myself and I would guess most ANY engine builder who is looking for the most power from an engine (NASCAR, Formula 1, Karting, NHRA etc etc) The single ring piston , IMO, is a problem for those whopush their engine and want the most from it. We will see how much skirt collapse has occurred after more tear downs after this season is over. Preliminary inspections have shown nothing conclusive. This will be a time-line thing much like the previous 800 CFI engines with pistons and cranks..
Overall.. Polaris has FINALLY put out a powerplant that can compete with the other 2. Reliability has been good and should be better for 2020. In big bore form it could rival most any N/A sled out there. 2020 should be exciting for this engine..
