Mostly fits for:
All Harley CV 40 carburetors:
Big Twin 1990-2006
Sportster 1988-2006
All Buell models with CV carburetors
Not for use on other Keihin CVK carburetors
Replaces OEM:
27585-88
Package Includes:
1x Vacuum Slide Piston Assembly as pictures.
Don't settle for previously used slides or the hassle of import diaphragm membranes that are difficult to install. The original slide was not designed to remove and replace the diaphragm alone, and the factory has never sold these items separately. Replacing the full assembly does the job right and takes minutes to do.
Not for use on non-Harley models or other Keihin carburetors. Only for H-D CV40 carburetors. WILL NOT fit the non-stock race carburetors such as the CV44 or CV51.
Please confirm your old part number and size matches up with one of the part numbers and pictures above.
