[QUOTE="b'knighted, post: 97782, member: 59"] Yes, the Ds had flange mount Monoblocks with the same bolt pitch as 900 series Concentrics. Club shop also used to supply clip fitting adapters to carry Monoblocks and these had the same pitch as 900 series Concentrics. I believe that the 600 series was a smaller pitch, as used on smaller Triumphs. Two of my section members have been sold 626s by a localish Triumph dealer but, as they are smaller than the original 1&1/16" carbs, I'd opt for a 28mm which is over 1 &1/16" but under 1&1/8". Neither member ended up fitting them. One because his camshaft fell apart before fitting them and he managed to get his money back on the bike and the other because he took my advice and took them back to change for 928s. For Shadow or Comet I would use 930 which takes you over the original carb size. [/QUOTE]

The Series 'A' Rapide was known as the '********' Nightmare?
