Newbie here. Names Mike. Live in Tn. Looking at a 1981 CB 650 Custom with approx. 13k. Bike is in decent shape considering it's 29 years old. Good tires, smokes a little on start up and has an oil leak on the left outer most cylinder head. Tank has no rust. Runs and shifts good. Has the tool kit and owners manual. Owner is asking $1150. What do you guys think?
