The K model bikes have a dry clutch. There was an issue with the K models where the clutch would get contaminated with oil because of problems with the various seals. It depended upon how the oil check valve is sitting and how all the oil holes and the shafts were lining up. When the bike is on the jiffy stand, it is leaning towards the clutch side and gravity is going to cause oil to drain on the clutch if everything is not sealed. I would think, that a tiny speck of crud could also cause a seal to leak.
What you are probably going to have to do is drain the primary, remove the cover, take the clutch apart (remembering how everything was put together), clean off all the clutch plates, replace any seals that are suspect and put it all back together and then hope it does not happen again.
When you are all done fixing it, check your tranny and engine oil. one or both are probably low.
