The F0/F1 bikes have the same rear wheel inner spacers - p/n 42620-392-000. The 77/78 750 K bikes have a different part number (42620-ME1-405). Are they different lengths? Mine (supposedly from a 76 750F) measures about 106.5mm
If it's worth doing, it's worth doing twice.

It (42620-392-000) only cross references for the 75-78 F's.

Who has one for the late K's they can measure?
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

I have a 78 750K It has three spacers one is stepped that goes in the sprocket carrier I don't think it is the one you are talking about. The other two are short & long. The short = 25mm average long=35mm average. I have no idea what or where that 106.5mm would go. If you need the stepped spacer # let me know.

I'm talking about the one inside the hub - between the two bearings.

Oh I was wondering why so long. To bad I have it back in with the bearings sorry.
