This is an EVO motor, cam is gear driven. You did not say how many miles on the bike. The trailer ball means it probably has pulled something. Find out if it has had engine or clutch work done. Take a ride and see how the trans shifts.
Thanks Don, that sounds like real good advice. Take it for a test drive and talk to the owner and ask lots of questions. One of my main concerns would be -- I would not be comfortable taking a 20 year old bike across country for lets say a 2K mile ride. Maybe not even a 1K mile ride -- would you???
Does anyone here ride a 20yo bike on long trips?
