New 750k (f?) Project - and lots more questions!
« on: April 26, 2017, 07:18:24 PM »
Hello all,

hot on the heels of finishing my 1971 CB500 (my first (re)build), I've got the bug and wanted to do a 750.

I picked up a load of junk the other day - mostly rust but a lot salveageable:

5 frames in total, 3 of which are rollers, and two of those rollers have engines.  Separately I have another engine and tons of spare jugs, heads, covers, electrics, exhausts, etc.

The best frame, and the one I have a title for is a CB750K6.  The best engine appears to be from a CB750F2.

I have 3 K frames and 2 F frames.  Not sure about the 3 engines yet but I'll check the numbers tomorrow.

I'll have tons of questions staring tomorrow but for now I'm curious how interchangeable K and F parts are?  I know that the engine internals differ, and that the rake is different on the front fork.  Wheels and brake setups are also different.

Will I be able to put an F engine straight into a K frame?  and are the wiring harnesses, carbs, tanks, etc. interchangeable?

Really excited to get going on this next project with all of the lessons that I learned here on my first one.

Cheers,

JB

Welcome to Honda Hoarders Anonymous  ;D

I'm sure someone will be around with 750 info soon.

Tanks are interchangeable, most anything can be put on another frame with a little work. I'm adding K parts to my F.
