Further to my Lucas RITA post after finding the bike wouldn't start and thinking the worst i wondered across the road to my friend who actually restores British bike for a living for a moan and chat and to see what he thought of Boyer Bransten ignitions thinking i would have to replace, so we had a quick chat as he had to go out, and i bit later he handed my wife a print out of B B installation instructions which was thoughtful of him........this morning i open the back door and find a RITA AB11 unit sitting on the doorstep (he hadn't heard me start up the Trident later that day) Such a nice and thoughtful guy, i took it back to him this afternoon and expressed my appreciation and had coffee and an interesting chat about Vincent engines.
