I'm pretty sure the original run of Kinnikuman got a complete translation, but Nisei was officially licensed by Viz but is now out of print (with some volumes being especially hard to find) and scans of it are non-existent, and Chojin Tag is (as far as I know) barely translated beyond the first few volumes, and the Kinnikuman 2011 continuation has a few people doing scans (like Hercules Factory on Tumblr), but I'm not too sure if the releases are translated completely to the current releases.
