The Aluminum rims are cb750A, the M&H has a 16" hog rim, re-laced with SS spokes, it was on a two hole hub. The clubfoot swingarm is 22-24" Oddly the bike has a stock swingarm on struts. The rider off lanyard switch is a set of ignition points with a leather pad between them. Header is a nearly new V&H but a guy gave me the original 4-1 black pipe off the bike. Drag specialties mini tach, also in the pic are Koni's, Webers, early ARD. That tank should be black but was striped by the Englishman at Laconia. He was the east coast version of Von Dutch.
The bike had been stripped for parts sitting in a shop, I've tried to restore it with no photo's, There is a guy that might have one, I'm tracking him.
