  • 20DC Best in Class

    It was nice to receive an email today from the gent I sold my 20DC to off our stand at the Shepton Mallet show in February.

    He informs me that yesterday it won the Best in Class at the Exeter British Bike Summer Run! Such a pretty little bike; running well, cheap, too; a happy new owner, using it as it deserves.

    I prefer the singles to twins, less fuss, less smoke and easy starting, at my age I am not wanting lots of horsepower, Click image for larger version

      That's a late one, John! Also, it is surprising how much lighter the singles are than the twins. The 2T & 3T motors are heavy old lumps. Easy to upgrade a 9E to a 250, by swapping the top-end for a 31A version. It will then comfortably pull a higher gear. I'll probably end up buying another one!

        Or better still fit a 34A scrambles barrel and head gives a bit more power especially with the larger Amal carb

          Wouldn't work, John, without changing the crank to a 5 1/2" rod version too.

          I have a spare 34a scrambles engine on the shelf....

            Not sure but I think the 33A (1958/9 scrambles) barrel had shorter rod but these are probably difficult to find

              Better still, fit a Vale Onslow barrel!

                  You can machine 1/4" off the bottom of a 32A or 34A barrel, instead of changing the crank, which gets expensive.
