CV Performance, specializing in tuning and improving Harley-Davidson CV carburetion for over 25 years, is now offering the new CV Performance Vacuum Slide for Harley CV carburetors as a direct replacement for the stock OEM slide. The vacuum slide in a CV Carb controls or influences the majority of the carb functions including intake velocity, air/fuel delivery and mixture density. If this piece is worn out, the diaphragm torn pinched or cracked, or the vacuum port is incorrectly sized due to modifications, your bike is not going to run correctly or to its potential.
Several tuners and shops over the years have recommended changes to the slide vacuum port hole in their “tune ups” only to find those changes create long term problems to carb operation and performance. The New CV Performance Harley Vacuum Slide brings your Harley CV carb back to original specs so the air/fuel mixture and intake flow is optimized. The diaphragm is made of a durable yet pliable rubber material not found in other aftermarket applications. This provides the ideal amount of slide action required by these carburetors while maintaining the correct seal under harsh conditions.
Compatible with all Harley CV (constant velocity) 40 carburetors made from 1990-2006, and used on Harley Big Twin Evo and Twin Cam engines, plus all Sportster (1989-2006) models. The retail price for the New Harley CV Replacement Vacuum Slide, made to CV Performance’s exacting specifications, is $48.95.
The CVP Harley Replacement Slide is a replacement for H-D p/n #27585-88. It is not for use on non-Harley models or other Keihin carburetors.
