any cb750 frame experts out there?...interchangability of '79cb750f & '82cb750k

[honda919]

...i've got six or seven 70's and early 80's cb750's and am having trouble with a 79 cb750f whose compression is fatally out of wack, but is beautiful chrome/body wise...i also have a 82 cb750k with the reverse problem, its engine is pristine but body is shite....you can see where i am going here.... any expertise with the frames of these bikes and their potential inter-changability?....i was lead to believe they have similiar, if not identical frames, yet, i am having a hard time finding definitive information.....

They will swap directly.

Why not just swap the engine?

I believe that's exactly what he's talking about.  Yes, the 82 K motor will bolt right into the 79 F....Carbs/exh/all.  Use the 79's airbox.

...thanks woodsrider...that makes this process a whole lot easier...i didn't want to have both engines out only to find the engine mounts don't match up...
