Here's a picture of my '73. Sold it in Sept '02 to a collector out in Washington. Much faster than my Meriden Bonnie. Besides the Engine dying everytime I actuated the left turn signal, it was a great bike. You should be fine with the '73 750. Stay away from the '72 750 Combat motors. If you want a list of links for parts and what-not, give me a yell. Welcome back to Amal-Lucas hell.
