    Complete vacuum slide piston assembly for Keihin CVK40 carburetors found on KLR650 motorcycles. Replaces the original Kawasaki p/n 43028-1062. Slide replacement is recommended when the diaphragm eventually becomes pinched or torn, or normal wear has led to driveability problems.
    Our slide is now tumble finished and uses a stronger diaphragm for improved durability.

    KAWASAKI KLR650 1987-2018
    KAWASAKI KLR600 1985-1986

    As a manufacturer and supplier we are unable to provide repair or service advice. Please consult a factory service manual or a qualified motorcycle technician when working on your motorcycle.

    All vacuum slides are test fitted and inspected by CVP prior to shipping to meet specifications and are verified functional for their intended use. We personally inspect the diaphragm before shipping to be free of any cuts or damage.

    Manufacturer warranties the slide portion only (metal casting) against manufacturing defects for 90 days from purchase date. The rubber diaphragm portion is not warrantied after receipt and/or installation since the manufacturer or seller has no control over any possible adverse conditions that may occur. It should be noted that the rubber diaphragm is very delicate, and any mishandling including pinching the diaphragm with the cover during installation will cut or tear the material and is not covered by any warranty.

    For warranty issues please contact CV Performance in writing. If a warranty claim concerns any sort of defect with the cast slide portion of the assembly the seller will issue a RMA number to have the slide returned for inspection. An RMA does not guarantee acceptance of return or exchange. Upon inspection if the item is determined to be defective the seller shall provide a replacement in exchange only. This warranty does not provide for a refund or compensation in any manner. Warranty does not cover any time, labor, shipping, or other loss incurred by any party whatsoever.

    CV Performance reserves the right to deny a warranty claim due to factors including but not limited to; abuse or misuse, exposure to solvent or chemical, damage from overheating or backfire, any damage caused by the carburetor itself, damage or improper handling by installer, damage caused to the product from any other product or device, or handling by any third party shop or installer.

    CV Performance is not liable for any damages or loss related to this or any product.

    We take pride in selling products that either meet or exceed the original specifications. If you believe the product has a covered defect please contact us in writing prior to using the product through our contact form with a description and original order number so we may further assist you.

    Great slide and half the price of the one from Kawasaki. I originally bought a replacement diaphragm only on ebay which failed after a few months. This carb slide assembly with the diaphragm already installed is obviously higher quality. Glad I found it here.
