Just an update FWIW - Soupy gave excellent service, ordered on a Friday and delivered here in UK 3 days later on the Monday. Now all fitted with adjustable side stand (with professional help) The overall situation now for me is that with the stock seat in the low setting I am almost an inch lower than the low seat in its lowest position in terms of feet on the ground - which is pretty much exactly what I wanted, I find the stock seat softer than the low one, and I have a little less knee bend. The front was dropped about 30% of the rear drop.
Only done about 150 miles since the mod but it is feeling good, handling fine and much better on stops where there is a very adverse camber/hill or both together etc.
Got some OEM boxes nearly new - and after losing the will to live looking at the exploded diagrams of the lock mechanism (Mike) they are going into dealership today with my spare key. Larger screen on its way which I know is likely to need a trim - but after that it really feels like I am getting there.
