I just completed the same swap on my 1981 XJ650. The low mileage 1982 engine runs great. This discussion really saved me some aggrevation....
You know the drill... How much? What condition? Is it straight? Where you at? How much to ship? Did I leave anything out?
I know a guy who's got a really nice Windjammer for sale, but his bracket fits a Suzuki. Anyone out there got a 650 Maxim bracket for sale?
