So I purchased a new 650XT last month for my wife to ride. The first day I was riding around the yard and experienced this grinding noise coming from what I suspect to be the clutch/belt or CVT. It happen when the machine had about 1 mile on it and I couldn't reproduce it again until this past weekend and now it has 150 miles on it..
Conditions for the video - I was in LOW, going down a hill (on my driveway) and you'll hear the sound in the video.
I've owned a ton of toys, never had anything make a noise like this thing.. Before I hit up the dealer I wanted to see if anyone else is experiencing something like this..

I'm fixing the sidways video right now..
