Does anyone have any good resources for information on the original exhaust for the '79-'83 CB750K? I'm specifically interested in the 1980 bike info. I'm seeing exhaust that are labeled, Sankei 2043, Sankei 2075. And it looks like HM425A is the correct fit. I don't want to accidentally buy an exhaust that is for a CB750C.
