Well I was extremely disappointed to learn most of the rest of the "sandcast" bike was mostly KO stuff. Swing arm, center stand, side stand, front end, engine covers, oil tank, cylinders, carbs, head, even many internal parts to the motor. I can only assume when the bike was crashed early on and the bike rebuilt with a parts bike from 73up most of what went back on were the newer items. So now I have a ton of K3 parts to list on Ebay and CL that I had hoped to sell to the guy who bought the frame and cases. I was sick to hear the prices he would have given me if they were SC and not K3 parts
