It was a complete 55 KHK new rebuilt motor with a few parts. The heads, cam cover and primary were off. It has KHK cams, heads, ported and polished ports, new valve job, 1 3/4" intakes. fresh bore at .020 over. Bottom end and trans rebuilt. Sometime in the late 50"s a matched set of Dealer repair cases were installed. Numbers match title. The 3rd owner who had it rebuilt repaired left case at kickstand tab and right above clutch shell and Sportsterized it. Right case no repairs. I am the 4th owner, 130 miles on rebuild. Kevlar clutch. Runs strong like my 59 XLCH.
