It is a dry clutch so I'll inspect that thanks.
fontyyy, that exactly what it feels like, that the chain jumps. My rvf400 racebike will do the same occasionally too. Maybe its just me being sloppy with my foot . . . More likely worn dogs as it has been doing it consistently more often. I don't usually use the clutch for upshifts, maybe I try using it and see if it helps. Thanks for the advice!
