I took out the clutch plates just to check how they looked like. I assumed that there wouldn't be any material left on the friction plates, however there still was.
Problem is that the steel discs are blue meaning that they overheated.
I am going to change it soon, however I was contemplating to actually insert an old steel disc as an extra, so to make more pressure on the springs, and to actually use up all the kevlar on the friction plates. I'll keep you posted.
Here are pics of the R1 clutch plates
