A picture of what you are dealing with would help, clarify.
Need to try to determine source of leak to fix the leak. It is Motor oil or dirty Brake Fluid.
The clutch is hydaulic operated from the master cylinder and reservior on the left grip, it uses DOT 4 Brake fluid. The Motor oil leak is coming from either a leak in the cases or most likely the O-Ring where the clutch rod goes into the case. The slave cylinder has a hard rubber spacer/gasket that goes between the slave and the case. There is a weep hole in the gasket. Not sure why.
