School me on CVT clutches.

Hi folks. I own a 2016 Grizz that I bought brand new last spring. I put 1500 kilometers on it so far and it’s been flawless. So now it’s time to mess with it. 🙂

I understand that our bikes have a "wet" clutch with the primary housing filled with grease. I’ve also noticed talk about going to grease less rollers for better performance. Is it that noticeable? Advisable? Does running grease less reduce the reliability of the clutch system?
