I fitted a folding kickstart to my 80s Ducati, got a cheap folding kickstart from an autojumble and an old one with the correct spline, had the chrome stripped off both then cut off one splined end, welded the other on and had it rechromed. At that time a new Ducati one was about £200 mine was about £15.
