Now with regard to the size of the carb, this is where I see a "fly in the ointment". In addition to buying another carb, likely getting a new throttle cable and then getting it to run correctly in terms of jets etc. you may find just getting your CV carbs correctly sorted is easier and cheaper. The CV carbs on the Japanese twins ran very nicely in the day and if cleaned and fitted with some new parts can continue to do so. So while the single carb like I have on my Triumph is a delight when it comes to maintenance and tuning, it was built that way, once you go none stock it can be a different story and getting your single carb to run as you would like it to, may end up being just as frustrating as your CV carbs, perhaps more so.
The Amal on the Triumph is a 30mm, if you do go the single carb route I wouldn't go too big or you will defeat the object of easy tuning that a single carb gives. Large carbs can give poor idle and poor starting, only providing a performance edge at the highest of rpms and usually poor mid range and bottom end. For 55 hp, I cant see you needing to go over 34mm, but perhaps someone with actual experience knows differently.

My Triumph Trident Cafe' had three, slightly hard to tune, small Amal carbs, Jardine headers, .040" overbore 12:1 Hepolite pistons, 4 or 5 larger tooth rear sprocket and the bike kicked ass....650ed wrote: My BSA Cyclone racing engine that I bought from Gary Nixon had twin carbs, and I don't know of anyone who ever raced a 2-cylinder BSA that used a single carb.

Just learn how to tune and maintain the CV carbs and you'll be a lot happier.

check out the carb parts diagram at Kawasaki.com or partzilla.
Single carb. The Milkman made a manifold from copper tubing & put a single stromberg carb on his 750-4.
If you go with a cv carburetor, it might help to stabilize the air flow if you add an extender between the carb & air filter.

Exactly! If one has the engineering skills to build a proper single carb intake manifold and select and correctly tune a single carb as a replacement for a dual carb setup he must certainly possess the skills to simply clean and adjust a pair of stock carbs that are already engineered to work with that engine.
