76 CB750A Engine swap question

[John C. Moad Jr.]

Hey everyone. I'm new to this forum. I just purchased two CB750As for $800.  My goal is to build a cafe racer. I know automatic is not really the way to go, but it was too good a deal to pass up. I'm wondering if it would be possible to put an engine from a CB750 or CB750k in the CB750A frame? If I'm stuck with the automatic I'll deal with it, but I'd really prefer a manual transmission. Any help would be greatly appreciated.
Thanks in advance,
Johnny

You know, I have not heard or seen this mod.
I would expect you could do it but I also suspect it is not a bolt in either.
The A does have the nice point though of a frame mod that allows you to take off the head while in frame though.
So bottom line is the K engine will fit but you will probably have to weld on some mounting points.
If you can, maybe find someone with a K bike, doesn't matter the year, and put them side by side and take mounting measurements.

Does anyone out there have the measurements for the mounting points on a cb750?  I would really appreciate it.  I can't find anyone in the area with one that I could measure myself.  My goal is to put a Cycle X streetfighter engine in the more robust hondamatic frame.
Thanks in advance.

I will see if I can dig my bike out enough to do some measuring.

The motor mounts should be the same IIRC.

Ive got a 72 cb750 that I just took the engine out  of & could take pics & or measure if you still need /want
