I will also be looking for a 750 (hopefully K7) to restore soon, had one from new and loved it, eventually sold it after 10 years but now I'm at an age I want to get another one and restore it if necessary. D&K seem ok but its a long way from Aberdeen so will have to plan it !!
This was mine when it was a couple of years old, we were on our way to our first European trip (Switzerland and back) and it was a fantastic holiday and memories, plus Deriboots !!
