My 08 Street Glide was leaking a little oil from the primary (where the starter joins the primary). My local Harley Dealership said it was due to an aftermarket starter that was apparently already installed on the bike before I bought it (I purchased the bike from a private individual). After installing this used OEM started, my bike no longer leaks. The product came packaged & secured really well! Great quality used product at a really affordable price!
