KZ750 Carb - Remove Diaphragm / Slide Assembly?

I just purchased a KZ750 project bike and I'm cleaning the carbs. The repair manual that I have says to remove the diaphragm / slide assembly. Can someone tell me how to do this with out damaging the diaghragm? It doesn't seem to want to come out. Thanks - Dave

Is the bike a 750/4 with Keihin CV34 of Mikuni BS34 carbs ?
So. you have the tops off and the spring out ? What's stuck ?
Will the slide move up and down or is it stuck ?
The egde of the diaphrams fits into a groove in the carb body just under the chromed top. Is this stuck? Dried up gas/gum ? Whatever you do dont put carb cleaner here. I dont think carb cleaner will be good for the diaphragm. I'm not sure what to suggest. Maybe WD40.

Hello, David, and WELCOME to KZR!
We're glad you're here!


Here's the link to a pretty good article about refurbishing CV carbs.
