I Now Own a 1972 Yamaha TX750. It seems to have quite a few Electrical issues. Are parts still available? I believe I Need a whole new Wiring Harness. Have you or anyone you know been through this same thing with the same bike? If So, I would Greatly Appreciate Any constructive feedback. This Bike belonged to My Father, who has since passed.. I would Love to get his bike on the road again...
