Why is the Matryx so heavy?

By the part numbers it looks like there's a new throttle body for 2022 850s. Injector numbers haven't changed.

Here's where I found it (can't link directly to model, but Pro RMK Matryx Slash is in there):

 
Haha, True... sort of. They did know how, up until the arrival of the XP I think. So it's more like they forgot...

They might think that a crappy recoil will balance the crappy secondary on the other side of the sled. "Balanced uselessness" or something.
(and before any faithful Doo-fans rip my throat out, I currently have a Lynx 850 and have a Doo 600 on order so I know pretty much what I'm talking about)
That crappy recoil has been almost the same and interchangeable since they dropped the metal one in 99/2000. I can't even remember how many I had to rebuild in the early 2000's. Well, until the 850. But same thing, 1/3 of my 850 sled recoils have failed.
 
What’s interesting, most of the 2022 parts are already listed. Except boost.
The NA 2022 ignition parts, as of last weeks posting, are identical to the MY2021.
Unless there is a 2022 running change, I’m not looking forward to an updated system right now. Maybe it’s a supplier issue. But ......
From what I have been told from guys who rode it, it is because the Boost isn't figured out yet. Clutching/odd running/? Can't post part numbers if they don't know what parts to use.

I will sneak some BRP tech tips in here ;)
I took the silencer off and taped the recoil with reflective tape first thing I got the sled home, have been running it 3 seasons without problems since, (recoil start only on my sled). So it seems the problem, or at least a big part of it, is heat. Keep heat away from the recoil and it will live longer.

On the Boost. It will be interesting to se how the production Boosts will run. I've had several Polaris sleds over the years and a fair number of them has been... well lets say less entertaining, than the strong running non EPA approved pre production sleds that were demoed the spring before. I truly hope they run well, there is nothing better for all of us, regardless of what sled we ride, than an OEM bringing out a fantastic sled! Competition results in progress!
 
^ Yup, I suspect the same thing about pre-production sleds. There's a good argument that the demo sleds for the rollout of a new chassis or big update are built better than the average sled off the line. I'd be pleasantly surprised if guys who've rode both can't tell any difference, but I'm betting Polaris works hard to make it perform like the demo sleds. How close they get on that, or how durable the turbo setup proves to be, is anybody's guess at this point. The 850 wasn't perfect out of the gate, but hardly a disaster (especially with the fixes for '20); not sure if the turbo is an "easier" project or not... I've been following (and riding) Polaris long enough that I wouldn't bet on a grand slam, but I'd say pretty good chance of a home run.

Not making any predictions but 9lbs of boost on pump gas at 10,000' is ambitious. And even if production is the same, those demo sleds are getting checked over as soon as anything comes up and looked over after every ride and any potential issues are likely getting full diagnostics and addressed before anything catastrophic happens. Consumers aren't like that, especially on a big pow weekend on a warranty sled. All that said, I really hope it works because I want a 2023 165' Boost to go with my 155" NA Slash.

That is true, I remember that now. Heat tape.

I remember in 01 or 02 at Arctic Man in Alaska, Polaris had demos. I rode a sled, probably a 136 or close. Actually, it was probably a 121. I was SOOO impressed with how fast and snappy it was for an 800 at altitude. When I gave it back, I looked at the hood, it was a 600. That was the year that they got caught demo-ing modded sleds as stock. It had had head work done.

Lol my 670 and even my 96 sls 500 both have zip ties holding the recoil starters on hahaha

Probably so. I do on my turbo rigs or "mods" for the most part. This is and has been one of the biggest issues with turbo sleds in general. Guys with no business riding a turbo mod treating it like a $2 *****. To an extent I intend to "abuse" my snow check via hard riding but not in terms of maintenance or upkeep.

Some more pics possibly not shared yet? Stoked on that color combo too [emoji119]

I just re-read this and remembered: I have not had a problem with an 850 recoil on any sled that had an HPS can on. It was all with stock cans. Hmmm..Good point.
