When I picked up this '77 CB750 a few weeks ago, I tried to put it on the centre stand when I got it off the trailer....it wasn't happening, and I thought, " oh, c'mon, if you can do a Concours, this should be easy". Nope.
Then, I read that stock shock length was 13.5".....just ran out and measured: 13"....yup, that would do it. Happy I can still hide my age and diminishing Hulkism.
