He is restoring one and a member here. He restored a 750K0 but sold it and in now restoring a K2 750 and a CD175A sloper.
Mine I bought from my mate at school for £65 (including transferring his insurance to me, those were the days) and sold it about three years later for the same price. If you look at the photo there are two small dents in the top of the tank, where the PO says he had a spill and his nuts hit the top of the tank causing the dents. Brilliant little bike, really fond memories and was still licensed in 2008 (OKH531F)
I will get Jock (bobthebuilder on here) to contact you.
