My '03 Heritage started leaking oil. :small3d002: Looks like it's coming from a sensor or sending unit behind the front exhaust pipe, right side of the motor, a little below the oil filter housing. It has a single lead wire to it & it faces to the front of the bike. I don't have a book on this bike yet, so I'm wondering if anyone else has had this problem and what sensor or sending unit this is. I'm thinking to pinpoint the leak, I'll have to leave the bike running after riding & look closely to find the exact place it's leaking.
