I started the cleaning process today. This being my first time into a set of keihin cx carbs. I am curious if the jets that are original have this mark on them? It is going to weigh into my choice of re jetting for air pods if they aren't original. Well thanks in advance guys. Also Is it normal for the accelerator pump diaphragm to be rusted on one side? I'm really bummed randakks is out of rebuild kits. Just hear great things about them in the past.

I don't know if the rust could be considered normal but as long as the rubber is OK that should still be usable.

Have you tried rejuvenating rubber with propylene glycol? I heard that it can help extend the life.
