The rear wheel on my 1977 KZ1000A1 has gotten some water inside the rim and it's pretty rusty. It looks OK on the outside but when I went to put on a new tire the insides a mess. I have a rear wheel from a KZ1000B1 (the cast aluminum LTD model) thats is good shape and it looks like to may fit. Before I spend the time and money to get new bearing and seals I was curious if anyone has successfully mounted the 16" LTD cast wheel in place of the spoked wheel. FWIW, I had a 16" rim laced onto the rear hub when I got the bike so at least I know a 560x16 tire fits OK.
