Real 850 Feedback from you guys!

[FatDogX]

Come on man, you have to be riding yours gives us an update on yours.

I wish!!!!

This is the worst start of the year I have had in well..........years!!!!

Between work and being sick, I still have a big goose egg on my odometer....

I'm hoping, in the next week or two we should be heading out. Hell normally I would have two trips in already.......this year sucks!!

Uhhhh yeah, get that thing on the snow!

To start let me say I am a Ski Doo guy. I've been on them since the first Summits came out in the late 90's. I have a good running Gen4 850 165, along with several other 800 Etechs. Just as a back ground.

New this year is the 850 174X3 with currently 125 miles. I have been nervous until yesterday's ride. It was pretty doggy, I know it has to get through break in. I have stayed with it, yesterday it finally started to really wake up. Before yesterday, it would not get above 7,800 rpm. It started to finally spool up to 8,200 yesterday. Power is smooth through the pull. I am starting to like the ride of the Axys chassis more. I am purposely staying on the Polaris until it's fully awake and ready for a real comparison before riding my Gen4. Don't worry it's getting some attention from the boys. I think a couple more rides and I'll see which one is preferred.

The Ski Doo has a Diamond S can, I will put the a Diamond S on this as well. I can't get them to answer the phone to see how long the lead times are. I intend to keep them equipped the same and do real side by side comparisons throughout the winter.

I used to live on this site, but now it is a random visit. I will post additional thoughts as the season come along. Still need much more snow in Northern Utah.

Man, some of these threads make me think I should have "survivors guilt" lol..
Admittedly only 3.5 hours on mine so far, but it's been flawless.
Starts first or second pul, no blubber on bottom end etc..

Had it do the 5500 rpm-ish bog once yesterday, but one thing I noticed is it was after a lengthy lunch stop.
I let the engine temp come up, but the pipe temp would still have been fairly low.. once a few km's were put on and everything back up to operating temp, it's never done it..

Did a couple road races with my 16-800, that has a bunch of goodies added, and the 800 would leap out to a lead, but the 850 would just motor on by

163" x 2.6"
150ish miles - hours is a mystery i dont have time to look at.
Skis run in center position (37").
SLP Blue/pink 66g weights. Riding elevation 8-11k.
SLP picnic can.
I run 91 Eth fuel (91 non eth fuel in utah doesnt exist), but sled uses the 91-non eth fuel map. (living on the edge)

Sled runs 8200-8300 all day long at elevation in deep snow. Anything below 9k will see 8400 and ill hit 8500 below 8000. I was considering going to 68g weights, but the sweet spot for our zone seems to be 67g with the slp mangum force weights (i think its 67.2g ).
The sled is an absolute tractor and is very deceptive in its performance. Its finally starting to feel like the sleds I rode for demo last year. It doesn't feel like its out performing last years 800HO axys until you put the two side by side in the deep and you are wheeling out over the top of the short steep creek bottoms and the 800HO has to sidehill out from half way up even with a track poach. The power curve is smooth in its delivery and so its hard to "feel" like its a better running sled until you smoke your 40lbs lighter buddies on their piped 800s.

I do get the occasional fat/rich bog on the bottom. It seems most often I can get it when cruising slower-medium speed through trees without punching throttle for a minute or so, and then let off and go to full throttle. Almost like I loaded it up on fuel by running consistent low RPM throttle. (Think slow down hill elevator to dropping around tree, to full throttle back up hill, thats when it happens, but its only about two times a ride, not consistent). I truly think this is a mapping issue that will have to be factory corrected or controller corrected.

quotes from people who rode my sled:
"I absolutely love your sled, its the best handling sled i have ever been on and I can carve anywhere I want on it. I'm not giving it back" - female rider
" I love this sled, cannot wait to push it to the limits once snow gets deeper"

I do think you are onto something here. The underpants dyno isn't as revealing as we'd like to think.

One thing that is apparent is the crank *is* heavier, its also a stroked motor. Those two things means you aren't going to have that snap the 800HO did.

...but once you are turning the motor past 5000 RPM, it just keeps on pulling. And frankly, its not a total dog under 5000.

I would look for Polaris to revise the crank in 1-2 years (kind of how the 800 HO motor is really similar to the old CFI 800 with a few upgrades - including a lighter crank)

THAT'd be a weapon! In time...

Still, Phatty's point is something I noticed, especially turbo'd. I was pretty underwhelmed until I started riding with buddies on 800HOs that I know are setup well. That's when it was apparent.

EDIT: and by "apparent" I mean I'm running less boost and absolutely have a stronger running sled, especially in the midrange, its so smooth...and I'm not even doing anything crazy with clutching at this point.

In the future, mou mean like an 850HO?

Great descriptions that really mirror what I felt. We were on some familiar lines/climbs on the weekend that I have run dozens of times on 800HO's. With the 800, you have to work the slope and have a good route to make it out in 1 shot. On the 850....you can wheelie, ride like a total goon, and still make it out no prob. Get slowed right down and still make up speed. The way the power comes on just seems to get and keep the sled "on plane" very well.

I also found the same thing where it can get a little burble-y when poking along at slower speeds. Agreed that it just feels rich in the low/mid....but I'm not out of break-in, so who knows.

where have you been riding?

I got over 20 hrs on mine now, just fouled my first set of plugs, it does girggle once in a while being at a constant low rpm, iv also noticed it takes 16 hs ish before it really wakes up. Mid range to top end, this sled is a rocket, it gets on top and just planes.

 

[edgey]

Update on mine 232 miles the exhaust temp sensor went bad on the can. All stock except for X3.2 and pro gears, going out next week with some different clutch setups.

Big thanks to the Polaris dealer in dubois already has the new sensor in and will pick it up when I go back out.

 

[dktraw]

250 miles and about 13ish hours. Have had zero issues so far. Pulled a cord though on a belt at 230 miles, thinkin my offset is not correct though.
Sled absolutely rips! Deep wfo climbs or chopping throttle in tree's, its 83-8400 rpm. Builds ground speed like crazy. My 17 Axys with Carl's stage 3 kit could not do what this 850 does. And my brothers doo 850 cant keep up either. Very happy with the sled so far. Does seem very rich on bottom and mid range, but not to worried about it honestly, don't spend much throttle time there anyways!

 

[PCDan]

Just crossed over 120 miles. Kept it mostly under 6k rpm for the first 90 miles.

The thing woke up big time on the last ride. Tached up over 8200 riding at 9K feet.

Drag raced my son on our 155 2017 Axys (500 miles) with an SLP Stage II Kit ...the stock 163 850 crushed the 800. I don’t mean just won, it crushed it.

The 850 has way more low end and it pulls harder and longer than the 800.

Just put the SLP can on today ... probably not even going to mess with getting the pipe ( since it probably won’t fit anyway)

 

[greasemonkey3406]

Finally got out for a little rip on my 163 2.6". Everything stock with 74g weights at 1800 ft. I only put about 35 miles on it so its not much of an indication of anything yet. At first it wasnt too impressive but I have noticed an improvement so far. Seems to get more responsive as miles go on. I can hit 8100 rpm so far.

 

[TRS]

The eight five-0 is getting very impressive.
A helix and secondary spring change today, utilizing Stock Polaris weights, made a big improvement in performance.
It hasn’t had a hickup. I’ve ran it hard for the 4.1 hrs and 135.6 miles on it.
We need snow as does many other riding areas.

My dad and brother both have 163 850s with about 13 hours and 200 miles on them. My dads is electric start bone stock. My brother just installed a slp can (which melted his pull rope right away) and has the pro gears on his. They both have ran great besides they have a little issue with run on when letting off the gas occasionally. Both sleds are turning 8150ish @ 6000' with polaris 72 gram weights. The sleds handle amazing and flat out rip. My brothers sled is quite a bit more responsive and runs away from my dads. My dad will install the pro gears before next ride to see if this is the main difference or if its the e-start.

We did some drag racing across a lake today and I ride 2012 pro with a silber turbo on 10 psi with indy dan clutch setup, gear down, 2.6 155 etc. We both pull away from my dads sled. My brothers and I are dead even out the hole and I have a very slight pull on the top end. Like I said these new 850s are impressive, my sled would smoke their 800 axys last year in a drag race. They don't have the instant snap down low like the 800 but we plan to play with clutching a bit. They climb effortless and are very responsive to rider input with the narrow front.

 

[sumtinwong]

its quite refreshing to hear good things about the 850s..... thanks all

510 miles on my 850 pro 155 all in the Yoop really pulls hard now with Thunder Products clutching no problems at all so far hope it continues.

 

[glowa]

so I am hearing that the SLP can is melting pull ropes. WTF is up with that? Such a stand up company and such a stupid mistake?

Just to clarify, your 850’s are running 72 gram Polaris weights at 6000’, stock. I’m missing something here.
Along with it stays with a 10# turbo.
I need some video.

 

[L. Perry]

Me too. Had a short ride with a guy this week on one, Said it would run with a turbo. Didn;t realize I was sitting on a turbo, didn't run with mine.
Only have a couple hours on my wife's 163, Have to admit for a bone stock sled it is very impressive, but is no turbo killer.
