New to Can Am…. Is this Normal?

Hi guys!
So this is my first Can-Am and I’m still learning what’s normal and what isn’t.
My machine has 140 miles on it and I ride in low range 98% of the time since my terrain is mostly soft sand,clay,mud and water and I do tend to hammer it wide open a lot!!!! I only run high range when I can rip for a mile or more on fairly solid trail. I bought a Snorkel my ATV kit for my machine( Very nice, high quality parts) and installed in on my machine since I think the factory set up is a joke, especially on a factory "mud machine". During my cleaning this morning I inspected the screen on the exhaust side of the CVT snorkel and found it to be almost clogged off with rubber dust from the belt. Before the snorkel install I used to see a little rubber dust on the side plastic with the stock snorkel as well. I have never smoked the belt and don’t think its slipping at all. It engages at about 1850 RPM in low and this thing screams!! Should I consider this "dust" to be normal or do you think I have an issue? Thank you for taking the time to help!!
