OP is from the states, so $2200. At that price on an 82’ special I’d be hesitant to buy if it needed work. “Good condition” and “runs well” are very subjective terms. Pics and more info are needed. Changing oil and cleaning carbs are a yearly maintenance issue and doesn’t mean anything. A lot of dudes will go apeshit with a can of carb cleaner once a year and say “carbs cleaned”.
Cafe racers, bobbers, and choppers, I get it, truly I do. They are terrible first bikes. These forms of motorcycle suppose that the rider is well aware of the machine and can handle the drastic change in riding style as well as maintenance. Stockers are easy, you can get manuals and unwind neglect and mistreatment. The former, presume that the owner has moved beyond this understanding to a more universal one and can apply these concepts to any machine. I love XS650’s but I’m also very well aware that they do not yield a high value outside of a very limited range of models and years. With that being said, you’ve found a blue gill in a well stocked lake, I’d throw her back and keep finishing if the juice is not truly worth the squeeze.
