On a B31 is it possible to adjust riders foot pegs position (to lower) especially on right side. ?
Right side has tube with a fix pin
To locate in a hole on engine plate.
You should find the tube has a fine spline which the cast footrest fits on, for height adjustment.
It’s not uncommon for these splines to get damaged and for it to (very) hard to slide the footrest off the tube/spline.
I use a slightly modified car ball joint splitter (threaded bolt type) to remove my B31’s left hand footrest.
