When I started the restoration of my R90s about three years ago , the first thing I did was send both carbs off to be restored . They came back looking great at the time I didn’t notice that the cable adjuster coming out of the top was straight rather than being angled at 50° , thus allowing the cables to come from the centre of the bike out of the carburettors . I’ve tried to get replacement elbows but they seem to be unavailable. The new plastic top PHM carburettors have the spares available but they are 6 mm thread and the old metal top carburettors are 7 mm thread. Can anyone offer any advice, know where I can buy replacements or used old elbows that I can use
