Not sure what parts books you are looking at, but RDs & Big Twins have had wrist pin bearings since 1956 30hp. They kept getting better as far as the cage design, but by 1962 the bearings & cage on the wrist pin were fine much less ’73. Those motors are true 50/1 motors. Whether you chose to run them at that mixture is your own choice.
Same with the fixed high speed jet. Unless you are going back & forth with regard to altitude as Mumbles mentioned millions of motors of all brands are running with fixed jets. You have the last year (1973) for magneto ignition which is great! You don’t have to fool with the pesky low tension troublesome system that came along in 1974-1976. Just my opinion, I may be wrong.
