Does anyone else have an anoying oil weep from there transfer case? My bike never leaves a drop on the floor but I can see the oil ever so slowly weep down from the side by the filler (under the exhaust pipes) to near where the drain is. I pulled the outer case, which is more of a visual cover and the O-ring looked dirty from the factory, so I cleaned and put back together and 2 weeks later same weep!!
