So when I do a cold start and the bike I'll get the loud clunk when ever the rpms momentarily drop. The noise is lessened when I pull the clutch in. So I'm thinking that the fluctuating rpms are causing the clutch pack to clunk. Now the clunking and fluctuations go away almost completely when the bike warms to 125f and up. Only today after some extensive riding did I notice the rpms fluctuating when sitting at lights at around 200f. Throttle bodis out of sync? Something else perhaps?
