72 and 73 wiring diagrams were basically the 70/71 diagrams. Yamaha added the electric start and just added a power wire from the coils to the safety relay......This is why it is difficult to work out from any other diagram as that R/W and Br in the coil area gets confusing. There is so much missing in the XS2/TX diagrams as well
Gator XS2 if you would like a full on Diagram i can email one to you...........this will blow up to about 900mm x 400mm
