Any idea what causes this?

Mine does it too, and has very low hours. How does that work on snow? Mine sux…just spins through all the gears, even with better tires

With Razr II tires it goes somewhat ok if there is good grip snow under powder snow.. other than that its pretty hard work to drive.

Sounds like a vibration of some kind to me, made more obvious by the slight high idle in the cold. I’ve had aluminum skid plates rattle from vibration that sounded just like that

Your nerf bars could be a culprit too

What's the temperature where you live? And what oil are you running? If you're running too thick of oil, your motor will make a lot of knocking noises until it warms up. It's real common with diesels as well in the winter time. If you like to ride in the cold, switched with thinner weight oil.

It's not vibration since it starts 2 seconds after start, it comes from engine. Sounds like cogwheel grinding or something like that.

I use Motul 5100 10w40 and temperature here is around -10c atm.. can go as low as -30+. It sounds like cogwheel grinding or somthing like that.. maybe from oil pump?

10w40 is pretty thick for -10 to -30.
Have you considered 0w30 or 0w40?

Ye maybe ill try that.. would be nice to know where that noise comes from and if its something to worry about.

Leave that jug of 10-40 outside when it’s -30 and then try pouring it out. That alone should convince you to switch to lighter weight oils in the winter.

10w-40 is too thick for that cold of temps. Your not getting proper engine oil flow on cold start ups. Heres the recommendations of oil weight for outside temperatures.

 

[Whitney]

In temperatures as cold as he is, I personally would use 0w30 instead of 5w30.
That is really dang cold.
Sometimes in frigid weather I run thinner oil than is even suggested.
These modern 0w30 oils are pretty sweet for cold temps.

 

[Whitney]

I'm not any expert, so a bit reluctant to recommend things.

That being said, this has been what I use in winter, in Canada, in many things, including my farm quads that get used a lot.
Never had any oil related issues using it.

Its not -30 atm and it does same noise even at +-0 so i dont think its oil that is causing this.

0 is still too cold for 10w40.

c, not f

Aluminum skid plates can vibrate at certain rpms. Mine vibrated like crazy at 2400 rpms. I removed them. My latest vibration was my ASV clutch lever bolt being slightly loose. It was so bad that I thought something came loose in the head. As for oil, Cuervo recommended Amsoil powersport 0w40. It covers all operating temps I will see from 0 to 115 degrees F

This sound comes from engine, left side of it. Yeah gotta go with that oil, seems best choice.

 

[Jani]

Ok you were correct, noise came from the nerf bars I was almost sure it cannot sound like this but i was wrong.

 

[raptordude]

I called it early on glad your engine is ok
