I got the set of ISO grips and figured a perfect time to lube my cables. I did the bag method. Then I noticed I had what I thought was grease on my left hand and started looking for the source. I pulled the clutch lever in and there was really black oil all around by the barrel that holds the cable. I have been cleaning it now every day with a paper towel, it seems to be drying up, but will it ever? I never got so much oil down the cable before that it would do that. The black must be the previous oil from cable or sheath.
