Does anyone have a chattering/buzzing noise coming for the cvt, it sounds like a worn loose chain. I thought it may be the cam chains but when idling the engine sounds smooth and quiet, as soon as you rev the engine and the cvt starts turning the sound starts, at the moment it's the most annoying part of the buggy

Mine has some sound when the wet clutch engages but its more like a low knocking sound. Some have said when their one-way bearing had an issue it made a sound more like what you are describing. Otherwise there isn't anything in the two CVT clutches that can make that sound that I am aware of. There is the support bearing in the cover for the half shaft. Those are just bearings that can make some odd sounds when going out.

Does anyone one know if the support bearing in the CVT cover is a open or shielded ball bearing ?

It is a sealed bearing. I don't know whether its a ball or roller type though.

I vote for the one way bearing as well. You could be getting chatter from the wet clutch. Make sure you are running JASO oil. There are miles of threads about oil though. I was getting some of the noise you are describing with whatever the dealer had put in. I swapped to rotella t4 15w-40 and had a lot better engagement and less chatter.
Currently a 2016 Can-Am Maverick XC dps. My first love but we've parted ways: 2016 cfmoto zforce 800ex eps black and teal with black wheels. Uni filter. Homemade intake snorkel. Homemade belly skid rails.

The Nosie has got worse tonight to the point I need to investigate further, where is the one way bearing ? Is it on the wet clutch shaft ? (4050 miles)

Yes, it's on the wet clutch side with the bell. The manual will show it.

Do you know if there's an upgrade for the std bearing ?

I don't know of any. They have been known to come apart but otherwise last a very long time...wear-wise. There has been more problems with the wet clutch shoes and springs then the one-way's over all. When a one way starts to fail, there is a loss of engine braking. Also if you can turn the primary one way but not the other without turning the engine over, it's probably still OK. Once you have the outer cover off you can test that.

Welcome. Good luck. I hope I get as many miles out of mine as you did.

There are no one way bearing upgrades because it is not really a "Bearing" as we all know a bearing to be.  The "balls" on a one way are oblong and flat so they grab when going backwards and they have small hash marks on them to help grip.  Factory is your only option.  With that many miles if it was me I would just replace the wet clutch while in there.  It may not be bad but when/if it goes bad it sends friction parts and metal shavings through the entire motor and its a complete tear down and replacement of ALL bearings.
I can imagine a world completely at peace.  A world where there are no weapons, no war, and no violence at all.  And I can imagine us taking over that world because they would never expect it.

Agreed. If you have to go that far, best at least replace the wet clutch shoes and springs as well.
