ok, you can all stop looking for a wiring diagram for my DT resto, local bike shop has found and given me a copy, no charge, the young fellow is new and dosnt know me from a bar of soap, little does he know i bought my first roadie, a 1976 K6 750/4 new from there in 76, total of 10 bikes I think in 38 years, so I think he's done well on a simple request to buy a manual, sort of restores a bit of faith in your local bike shop.
