CB750 - will a '72 engine work ok in my '75 frame?
« on: December 30, 2009, 06:58:12 AM »
Would there be any issues I'd run into if I transplanted a '72 model CB750 engine into my '75 model frame?

I found a spare for a good price, and I'm thinking of buying it to build it.

I've got a 78 engine in my 71 frame. ;)


the 75 will fit in your frame with no mods
everything I say is pure speculation and
I have no idea what I'm talking about  ._.
