I can only recall one roll pin on a K1 and that holds the kick start spline and that one is too small
I have a vague memory of seeing a master cylinder with a roll pin in vertically between reservoir and lever pivot
Does the 750 have the same right footrest layout as the 400?There's a roll pin to locate the spring that holds the footrest up when using the kickstart.
