I just sold my HD and have been riding since I was 15, being 50 now. My brother has a 1973 honda 750. It has 300 miles on the new engine he put in and it has been sitting in his warehouse, next to his 77 vet. He said give him 1k and it is mine. I love this bike and rode the help out of one just like it in the 70´s. I know a shop that deals with older bikes so that is a done deal. Should I take this project on? Those of you who have gone down this path any advice?Also, I hear of a conversion kit that will allow 4 cabs into one big mic. Does the conversion kit exsist?
