Ks LEV creaking at seat mount

Anyone else have issue's with this? I have a LEV-ti and you have to pull it apart and put carbon paste on it a few times a year to keep it from groaning when you weight the seat differently. Its really annoying when it makes noise and the only thing I ever found was to put carbon paste on it. There is no serrations in the seatclamp area to grip at all and the lower plate the seat sits on is carbon.

I have a eTen which is KS's cheapest model with a single bolt head. It never makes noise but its serrated inside the clamp.
