    I changed my oil a couple months ago and all was well for about a month and then started leaking oil, I thought it was coming from the oil filter because the wire wrap directly under the filter was wet and the oil was dripping down the wire wrap to bottom of motor and I did tighten the filter about a quarter turn but its still leaking, could it be the oil filter mount?

    If the filter had not been tight in the first place perhaps some dirt got on to the filter seal and caused the seal to fail
    might be best to remove the filter and clean the seat that the seal sits on and fit a new filter smear some fresh oil on the seal and do not over tighten the filter as it can deform the seal and cause it to leak should only be hand tight

    Do you have an adapter or a oil cooler on the bike?

    IF you don't have any oil around the front cylinder base and the leak is localized around the filter, it is probably one of three things - First it may be nothing more than oil spilled during the filter change that is just now working its way down and starting to drip. It is almost impossible to change the filter and not get some oil spillage.

    Second, the oil filter gasket is leaking (making it tighter may only make the problem worse) - Or the oil filter bracket is leaking (This is me hoping that your cases aren't cracked or leaking).

    I would try the cheap fix first and change the oil filter. The filter may have visual signs leakage (gasket creased, flat spot, cracked or wrinkled). After changing the filter I always spray brake cleaner all around the area to clean away any spilled oil.

    If you still have the leak after changing the filter, you should replace the oil filter mount "O" rings (HD # 11293, two required). Inspect the mount for cracks or warping and if it needs to be replaced you will need HD # 26261 (black) (includes "O" rings) or HD # 26274 if your motor is silver. Or you might want to use this opportunity to do a little chrome and add HD # 26321-99A Chrome Oil Filter Bracket ($69.95 retail).

    Hope this at least gives you a place to start looking.

    Hopefully not the front cylinder base gasket leaking, some times the case studs stretch and the base starts to weep then leak, good luck

    No problem. Remember to check your oil level after changing the filter - You will need to replace the oil removed with the old filter.

    ChopperDoc's first suggestion sounds like a reasonable one.That wiring harness is a bear to clean oil from;when it dribbles in from your filter change.
    Also,do you smear oil on the filter"o" ring when you fit it?If you dont,it can bind or bunch up,not seal properly and leak despite however tight you try and turn it.

    Just another CAUTION as I found on my 2000 FXDS.... I think your wires to the stator are the same as my 2000....

    I would Find oil IN and around these wires after a oil change NO Matter How careful I was (filter change leakage)...

    The Caution Is OIL would Fill INTO the "Stator Coupler Plug" and "Boot"... Leaking out After normal clean-up... Ride Wind blowing oil out again after cleaned once and re-appearing as a leak..... You get my drift?

    I would check and wipe out the "Rubber Cover Boot" and UN-Plug "Coupler" to make sure the connectors are Oil Free... Mine had enough Oil in the "stator plug" to cause a short at this connector.. It is worth checking..:D
