I wonder if Honda bought it back? Do they have "Club Registration" in the US? Over here in Oz, annual registration fee (including "third paty" insurance which pays for personal injuries but not vehicle repair) in some states can be as much as 600 bucks (US) per year, but if a bike is over 25 years old, it qualifies for "Club Registration" which costs around 90 bucks a year.
There are all sorts of restrictions therein, but the good thing is that you don't need a "title" per se, and a club official usually can do a "roadworthiness" inspection, and of course, being a club member, he or she will generally be a little more "sympathetic" than the government arseholes, and can then issue you a club plate. I don't imagine that the new buyer would be wanting to ride it every day, so "club registration" would probably be ideal in this situation.
I've been paying full annual registration here for the last few years, but as I don't need a daily rider (company car) I'll join a club and get my K0, K1 and Suzy GS1000S all put on club plates, and save around 1500 bucks per year. Cheers, Terry.
