CBAS5 and I videotaped what a good diaphragm sounds like when it's installed, and also what a bad one sounds like. There's a huge difference, but until you see it or hear it in person, it's hard to describe. I think the sound and the speed that the slide comes down are the two most important things. Those things you can't describe to someone really. But it's absolutely the best way to verify that the diaphragm is seated properly. The carburetor in the video is on a 2005 Sportster but applies to any CV carburetor mounted to Sportsters.
