Yamaha's documentation for the TX750 carries part number LIT-11613-41-73 and covers the 1973 model year. TX750A is the code on the machine.
Bikes of this generation are now mostly in the hands of people rebuilding them, and the original service book is the reference that keeps a rebuild faithful. It gives the clearances the factory specified, the torque figures for each fastener, the sequence in which the engine comes apart and goes back together, the carburettor and ignition settings, and the wiring as it was drawn when the bike was new.
None of that has been reinterpreted. Where a figure is unusual, it is the factory's unusual figure.
Before ordering, confirm LIT-11613-41-73 and read the TX750A code from the frame rather than working from the year on the paperwork.
