Just been on a 3000 mile tour of Europe and come to clean my bike,spot some Oil on the floor near the Rear Diff,I changed the oil before I left with the 200ml recommended,Both drain bolts are dry the oil was in a bit of a puddle where the flange meets the wheel via the Cushdrives,has anyone had any similar experiences,is there a tell tail which passes if overfull?I have completely drained the oil and left on side stand and the amount in catch container is approx 225ml,so over 10% more than recommended capacity along with whatever has leaked out ,have I blown a sseal something on the diff or is it just oil escape from slight overfill,Thoughts?
