Complete vacuum slide assembly for Harley CV carburetors. Replaces original H-D p/n #27585-88. Slide replacement is recommended when the diaphragm eventually becomes pinched or torn, or if the vacuum port hole has been modified by drilling 1/8″ or larger causing driveability problems.

New and improved! Our slide is now tumble polished and uses a stronger diaphragm for improved durability.

Fits all Harley CV 40 carburetors:
1989-2006 Harley XL Sportster
1990-1999 Harley Big Twin Evo
1999-2006 Harley Twin Cam
1994-2002 Buell Lightning, Thunderbolt, and Cyclone
2000-2009 Buell Blast

Not for use on other non-Harley Keihin CV carburetors.
