When you know how cvt works, it's very logical that it gets dirty quickly, it's many years of experience with CVT transmissions with various brands and manufacturers. Not to say a common thing. after all, it is in their interest that the parts wear out as soon as possible.
They do not repair or maintain parts, interest is only to sell new parts. Thus, they reduce the work force required for maintenance and speed up the sale of new parts. Your CVT components would last longer and the ride would be smooth. 12k with out greasing and cleaning high speed rotating parts..??🙃
The only thing that must be paid attention to is the force with which the screws are tightened. I think that the required force is stated in the instructions you have.
But ok, your market is more consumer, we in Europe are a little more enterprising in avoiding unnecessary expenses.
Edit.After all, in the official service, I was told that the strange noises are coming from the clutch due to dirt in the CVT. They officially noted that they fixed the problem by cleaning the CVT.Goodf
Good explanation. Thanks for your time, patience, and expertise.
I don't know whether it's a Europe vs. USA difference, regarding unnecessary expenses. I think there are a lot of people over here who feel the same way you do. In my case, I'm just old -- 76 -- and tired enough of getting down on the ground (I have an artificial hip*), and getting oily, etc., that I don't want to do that kind of maintenance stuff**. And I can still afford to let the shop do it. But if the bike will run smoother, I'm all for that, so I may actually give it a shot.
By the way, I still love doing electrical modifications, sort of as a hobby, to bikes. And the good news is that most of the time I can do all of that standing up. Check out my gallery,

** (In a surprise maintenance move, I sat on a low-height rolling work-stool and oiled the chain on my Royal Enfield Meteor 350 for the first time last week. I put about 2,000 miles on it last year, but I hadn't oiled a chain in 60+ years, and that was on a Schwinn.)
