Been notcing after my rides that the plastic clips under the swing arm is coated in "oil" and a nice splattering around the wheel too.
Seeing as wheel is coming off for a new tire, figured might as well check.
Inside the swingarm , other than some grease flung from the U-joints, is almost spotless. A small coating of lube around the hole for the plastic clip.
Set the CARC on the bench nose down while doing other stuff. Came back to find a trail if purple lube oozing out of the seal area. Pulled the fill cap to confirm it. Yup. Royal Purple lube inside. Guess its the CARC seal that's leaking.
