I think the inner primary seal on my 01 FXD with 8,000 miles is leaking.I'm getting a few drops of oil around the drain plug after a long ride. I first thought it was coming from the tranny vent but there is no oil residue on the vent tube and the oil leaking doesn't smell like gear lube. The oil is pretty clean so that rules out engine oil.If it is the inner primary seal what could have caused it to leak after only 8,000 miles?Will this require the removal of the inner primary? Is there anything else that it could possibly be? Is this a job a novice should try? Sorry about all the questions. Thanks for the help!!
