I've come across a 68 sportster that I checked out at a friends house that he is looking to sell. The only thing is the front cylinder is off and it has been exposed to the elements. The only thing that is some what protecting it is a trash bag that is covering the bottom end, the engine is still on the bike; however, the bike has no gas tank and is fairly rusty. My question to the community price would call out to purchase the bike?
