So I had my swing arm replaced and belt changed at HD, I know big mistake. Anywho I noticed some oil on my muffler and didnt think too much about it due to refilling the oil up and thinking that some was spilled. After about 25-30 miles back from HD I saw that behind my drive sprocket it was really leaking oil which was coming down onto my muffler. Is this oil leak from thier doings? It wasnt doing it before but do any of u have a valid argument to make to HD so I dont get screwed. Thanks Buelljek
