* Both the CV40 and CVK carbs are made by Keihin in Japan. But only the CV is specific to a Harley and has the bar and shield and HD name on the side. ((CVPerformance of the XLFORUM http://xlforum.net/forums/showthread.php?t=1729649&page=2)) \\ CVK is for Kawasaki and various other makes that contracted Keihin for that carburetor. \\ There is also a CV40 making the rounds that is distributed by a Florida company that looks identical but not all the specs match up. \\ There is no guarantee that any part (original or CVP) will fit those knock-off carburetors. \\ If your CV carb does not have the name Harley Davidson cast above the bowl on each side it is a knock-off. | * Both the CV40 and CVK carbs are made by Keihin in Japan.

If the plastic nut has stripped out, you can cut a piece of rubber tubing, slit it long ways and stick it between the nut and the knob when needed.

Upon perusing 1986-2006 Parts Catalogs for carburetor information, it's clear that the MoCo was trying to save space in these books at the expense of legibility. Below is a chart showing the initial intentions on the top and the MoCo's mis-interpretations on the bottom. They give no notations (from year to year book) on any changes to the nomenclature. I.E. one way to display a year/ model number is displayed differently in other year books. This chart is not complete nor factual in numbering but as an example only. | Upon perusing 1986-2006 Parts Catalogs for carburetor information, it's clear that the MoCo was trying to save space in these books at the expense of legibility.
