Primary clutch or something else?

After a little investigating on my 13 1100 I still cant find the source of my belt problem, tcl stage 3 installed with the snubber and updated secondary the only thing I can think still creating the heat I'm getting is maybe the primary clutch. Also under load (ie pin and wiggle situation) I get a nasty vibration and it doesn't come from the track feels almost as a belt chatter.
Any help would be appreciated I marked the snubber and it hasent moved since installe.
