Oil in supercharger hose

[cglg894]

Took the SC intake hose off of the SC last night to check for slipping of the SC and had oil in the end of the hose. The ski has been setting for about two weeks since last ride. Is the oil coming through the SC from the engine or somewhere else?

The supercharger seal is probably on its way out. It's almost time for a rebuild anyway...
