Thanks for the comprehensive explanation, Disston. So, it seems it's really just the tranny that gets the bad rap? And if I'm understanding correctly, just about any 1975 to early 1980 box can be swapped to the 1974 and alleviate the problems associated with the '74 gearbox?
I'm not sure how difficult it is to source a '75-'80 box, or how expensive they tend to be, but if I'm understanding correctly, the '74 R60/R90 are decent bikes, the weak gearbox notwithstanding.
