I have sold quite a few CB72/77 spares at autojumbles this year and really nice bloke bought quite a few parts off me, as he's seriously collecting lots of them. He told me yesterday he has a UK '66 Black Bomber CB450K0 that's completely original and he would sell if anyone interested as he's just bought a stash of CB72/77's and needs the space/cash for his smaller bike resto's. Not seen the bike but if anyone in the UK is interested then I could pass on details. He also has a later CB450 that he bought from D.K. Motorcycles as 'weather seized' but turned out one of pistons had disintegrated....so engine needs serious attention. He's in Lincolnshire.
