I owned a 73 750, got bearly used in 76. Talked to a friend who was a yamaha mechanic. He advised me to check the points before buying.... if oil run.... seems early 750s had a problem with the case warping. If no oil good bike. Was a little heavy but good for crusing. Had only 1400 miles when i bought... almost 10k when i sold it.. canĀ“t remember why I sold it now... been a lot of years since i thought of that bike
