For those of you that are doing some major repairs on your 83, such as transmission repairs or whatever, I suggest you think about doing what I did as a frame repair, even though you have not experienced a frame breakage as I did 4 1/2 years and probably 35,000 miles ago.
Even though I don't feel it is a common problem of frame breakage, I do feel that if you are serious about keeping your bike on the road and having the structural integrity it needs, this is something I think you should seriously consider.
