Dominator carburettors

Hi simon, These are monoblocks fitted with float bowl extensions which was a popular bit of "bling" in the sixties. the carb sizes should be about 1 inch . the carbs were current fit but I cant see what sort of manifold is fitted, Could be some sort of homemade adaptor as the early ally head was not supplied with twin carbs .If you can find an early single carb manifold it would be easier to live with.

Hi all I wonder if anyone recognises these carburetors and are they the correct one for a dominator 88. they look a bit to modern to me

Hello norton model 88SS april 1961 no to 1966 had this type of set up with amal monobloc 376/288 and 376/289 earlier models from 1959 to 1960 were monobloc 376/218 and 376/219 twin carb set up, but do member that both carbs have be in tip top condintion to get them to run right and to tune the running of both carbs to tune them you need to start with the left hand one first and take out the right hand side spark plug and run the engine on one cylinder at a time then both too get the tick over rigth now these look like thay could do wiith a good clean you can get a good caburettor cleaner but every thing needs a clean to a high standard to tune the carbs right, but you can go down the Single Carbuettor route they are a lot easier too live with, you only loss the top end power anyway , and in our days you never get anywhere to justify having twin carbs unless your going to be on the M-ways most of the time, have fun yours Anna J

Your bike wouldn't have had that rather weird twin carb manifold from new. The extended float chambers were, as previously mentioned, bling. Themonobloc carbs are correct. I would suggest you get hold of an original single carb manifold and return it to standard and then you have a usefulspare carb.

While a single carb will make life simpler the twin set up does make it more interesting even if a bit of a lash up and so typical of what hapenned back then .No self respecting cafe cowboy was satisfied with one carb. Unless it was on a goldie.
