OK, after listening to both youtubes mine does not do that.

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Ryker "Down Shifting" while engine braking

Mine does this as well some times, at low speeds when coming to a stop. Seems so common I dont worry about it 
But if there is a certain drive cycle to enable the condition, I can see how it would be a little bit of an annoyance as conpared to the otherwise very smooth and seamless ride of the Rykers

My first and last Canam, it also came missing the roller bearing in the drive pulley.

I have looked and looked and can find no information on why the condition when you are going downhill with the throttle closed or occasionally just coming to a stop. May just take the CVT cover off one of these days stick a GoPro and video what exactly happens. It can not be the clutch engaging and disengaging.
alrighty, took my ryker to the dealer to have the swaybar installed. (used brp credit from panels toward part and labor)
told them about the downshifting and they didnt think it was normal. tech said maybe a weight was stuck. this was sat 8/8/2020
they called me today, they were able to replicate it and the service manger used the word harsh to describe the downshifts. he reached out to brp dealer community and the dealers that had seen this problems say bad transmission.
so my dealer has a claim in for a replacement for me. bike is 2 months old 1400 miles and it has done this from day 1
yay

I am going to wait until Ddorand posts the outcome of his bike. Then if need be I will just take the CVT cover off and take a video of exactly what is happening.
One of my riding routes has a steep and long downhill and the bike does the same thing sometimes more than ten times. It is annoying and since I do not know exactly what is happening very concerning.

got a gopro. much better sound.
still waiting on brp to answer on what they want done, plus transmissions are on back order until late sept.
i will update as things start to move forward.

We will be going on an eight hundred mile trip shortly on the Canam and there was no way I would depart on the bike without knowing what exactly was happening and if a failure was imminent. Obviously it is not q question of any gear change being involved the Ryker has a CVT no gear changes involved.
The situation happens on over run, i.e going down hills with throttle closed and occasionally comping to an abrupt stop.
I took the CVT cover off and took a video of what is happening.
I am not an expert in CVT but the logical conclusion is that either some bikes were shipped with a faulty driven pulley spring or may even be that the specifications are out of line.
What happens is the the sheaves on the driven pulley (the larger one) open and there is a delay in the drive pulley taking up the slack of the belt so you get the jolt and the clunk as the belt gets slightly loose and then the slack is taken up. Watch the video and keep an eye on the belt on the upper pulley and see what happens when the now familiar sound is heard.
I am hoping that in our upcoming journey we will not have too many steep downhill situations requiring closed throttle decent.

And finally no, it is not OK the bike should not behave that way.

I think thats normal with this kind of gearbox - if you ride downhill 2up a steep road - she brakes periodically that helps a lot for the "normal" brakes - thats so fantastic, would not change it !! Downhill she is much faster than each Spyder-Modell and most of the motorcycles ..
With the Ryker I use most time the "brake" of the gearbox - different to our old Spyder-Modells, some say the brake-pads on the Ryker can work 50.000 miles !?!
(13.000 miles here in the Alps - 80% up & downhill )

better video of the noise.
also aregg made a nice video of the pulleys acting up with the cover off.

The CVT does not change down gears, there is no braking system involved there is an issue that am sure Ddorand will clarify soon. Here is my final video. I cuss myself for trying to save some money and not buying a Spyder.

Alright, I got an update
Brp is now acknowledging that this is an official issue now. My can am service manager called me yesterday with an update.
The brp engineers are studying the transmissions that they have changed. There is an issue with the design like you said.
They want me to wait until they figure it out as the issue isn’t guaranteed to be resolved by a trans change.
They said that the current statistic is a 50% resolution rate from swapping them. 5 of every 10 do it still.
There is no harm being done to anything on the bike by having this happen and it rides perfectly fine. So I am not worried about it just yet

It is interesting to me that people keep referring to the Ryker's 'Gear Box', when there are no gears (or box for that matter). It's all centrifugal weights, springs and variable pulleys.
I think the only damage you may be doing will be to the belt. I would say that over time, it may wear out sooner than with a correctly working CVT. But I would also think belt replacement would be part of the warranty fix, once they have one. It would be interesting to know what the 'Design Flaw' is. If it is a design flaw, and not a production or manufacturing defect. You would think all Rykers would suffer the same symptoms.

Thanks for the info.
So my 19 Rally is waiting on a fix from BRP for:
The "skipping" belt/clutch described above
Noisy fuel pump
Leaking brake reservoir cap
Fine by me as long as I can keep riding and they actually fix these issues.

@Baja Ron - from what brp is saying, there are a lot of rykers having this issue. they have replaced a bunch of transmissions, that is how they figured out it is an issue. the trans replacement isnt fixing the issue on half of them so no they are investigating the issue. when will your red sway bar links be back in stock? waiting for them to return so i can get a set lol
@Rob R. - fuel pump has a fix now. they are sending out the spacer for the valve. they have also confirmed what i have been fighting with people about in the FB group. a new fuel pump will not fix the whine. the pumps have not been retrofitted with the fix just yet. my parts are on the way to my dealer but we are waiting until the trans fix is found before doing anything since the only issue is noise and not performance. not a dire need to fix it.
@aregg - no hills where i live and mine does it all the time
@Baja Ron - pulleys are just gears with no teeth lol

Correct, putting a new pump won't fix the issue. Funny thing is....there was a post on this forum a while back from someone who had the fuel pump noise issue. He just bought a replacement pump (cost like $40), pulled the BRP fuel pump assembly out of his Ryker and just replaced the pump itself (not the whole assembly which is the pump, electronic module and mounting housing). Worked fine and solved the noise issue.
