The vacuum petcock on my Honda can be rebuilt but I don't know about the Kawasaki. I dumped the vacuum petcock on my Honda and replaced it with a manual. Since the replacement petcock for the Ninja is so expensive I might consider doing the same. On the Honda you simply have to remove the spring on the diaphragm and move it to the opposite side of the diaphragm, cap the vacuum port on the intake manifold and the problem is fixed. I've never had the Kaw petcock apart so I don't know if it can be done on the Ninja. You might be able to disassemble the petcock and clean it.
