Harley Carburetor history overview
Someone recently asked me what carburetor Harley used before the CV. I knew that the predecessor of the Keihin CV / CVK 40 was the butterfly model Keihin and that prior to that they used the Zenith / Bendix butterfly carburetors. Before that they used the Tillotson, Linkert, Schebler and the first HD is reputed to have used a modified tomato can! That question got me to wondering what was the progression of carburetors on the HD?
I have late model information but I would like to fill in the gaps of what carbs were used on what years. I also would like good links to sites that cover the history of the carburetors used on Harleys through the years
Carburetor series / brand:
Keihin CV CVK 40; Was used from 1988 (Sportsters), 1990 (Big Twins EVO and TC88) to 2006. These are the last carburetors you will probably ever see on a production HD.
Keihin Butterfly; Was used from about 1976 until the CV replaced it.
Zenith / Bendix; Was used from about 1970-1971 until the Keihin butterfly replaced it.
Tillotson; Was used from about the mid sixties until replaced by the Zenith / Bendix
Linkert; What years and models?
Schebler; I found very little info on this carburetor
Tomato can carburetor; Reported to have been modified to act as the carburetor on the first HD.
I would like to fill in the blanks and build a list of links to good sites that have historically accurate information concerning the carburetion of HD's.
I would also like to build a list of Harley racing carburetors. such as the SE Keihin butterfly, CVK 44, Holley, Mikuni (really just the EZ-kit.) etc. There were predecessors like the XR-750 special carbs. Any information will be posted and credit given.
If you have any information you wish to share, please contact me.
Here is a link to The Antique Motorcycle Club of America it is a very interesting site with great information.
