Hi Stephen
Yep your spot on, the cranked kick start lever sold by many dealers for A10 are not quite cranked enough.
Also to consider is how much end float the quadrant shaft has, I stopped my lever from marking the silencer chrome ( only now and then would it touch) by cutting an old bush down and fitting it between the kick start lever and the gearbox, I left room for an O ring next to the gearbox so it holds the lever out away from the silencer and helps a little to keep the box cover oil free and gives a bit of a cushion so you can't over do things.
