Stored inside or not... Theres always the possibilty of internal issues from how it was put away. They made 300k cb350s for the US market. Its a throw away bike to many. Its also a great bike for a million different reasons. That said, youre looking at new tires/tubes, battery, cables (if they cant be or werent properly greased), perhaps bulbs, cleaning the fuel tank, probobly replacing wheel bearings, a ton of cleaning, possible rust in the exhaust from lack of use, title transfer and registration fees, etc... So... That said, if youre willing to spend $800 plus at least few hundred more in wear parts and whatnot than go for it. Personally, Id see if they were willing to take $400, but Im a cheap asshole.
