I have been eyeing a CB550 that I found listed on craigslist. I went to see it today and it is, perhaps predictably, a little rough around the edges. The seat is mainly duct tape at this point, the turn signals buzz at you before the start signalling, the cut off switch no longer works, it has a little trouble idling (has to warm up quite a bit before it stabilizes), the horn is silent, and there is just a touch of rust on some of the piping. The owner claims that the carburetors were recently serviced. I wonder if it is worth the $700 to $800 he wants? Considering what obviously needs some repairs and taking into consideration what repairs might be needed in the near future. I am not the most mechanically savvy person, but I am interested and willing to learn. Part of the reason I am interested in this particular bike.
