Last summer I put a later-model stand on my '81, and I love it. (BTW, I was under the impression that BMW changed the center stand design for the '83 and later models, not the '82. Am I mistaken?)
The only installation hassle I had was the return springs — the later-model stand requires springs that are about 1 cm shorter than those for the '81 and earlier. The parts dept at Bob's could not find a reliable part # for the springs you'll need, so it's something of a poke-and-hope proposition. Somewhere in all these center stand message threads is a message I posted within the past year or so, listing the lengths of each spring. My brain's mush tonight, and I can't find it, unfortunately.
Replace the old center stand. You won't regret it. JT
