There was oil slowly dripping from my countershaft, so I replaced the seal and the leaking stopped completely. It was totally dry with no leaking whatsoever for about 300 miles. After my last ride I noticed that there was dirt collecting around the shaft where oil was very slowly seeping from the seal. Is this normal, or should there be no oil residue at all? I do like a clean engine, but the residue isn't enough for me to immediately worry about oil loss. Thanks for the imput.
