I wasn't suggesting your clutch had to be cold or damp, I simply stated even some stock clutches behave that way under certain conditions. The finish on the flywheel & type of lining/hub are what I was addressing in your case. If mounts-etc. all check out, I have installed truck & Hipo discs that chattered no matter what you did, some racing clutches are either in or out,there's no "sliding" 'em.
