Rusty, I would not stress over it a bunch. I trust my own work over some of the younger guys anyway. It's not a Honda decision to drop service - it's the dealership that probably doesn't have the manuals and parts in stock to make the repairs. Also a lot of older bikes get repaired and never pick-up because their repair cost exceeded the value the owner wanted to invest.
Your mixture problem ill get worse though in a few weeks as the weather cools down and the air becomes more dense. Why not just raise your needles 1 clip? That is - move your clips
down one slot - this raises the needle and it is the one circuit that will have the most dramatic affect on your cruise and top-end mixture. Nothing to buy, nothing to replace - a simple adjustment that can be done in a few minutes without gaskets, no carb removal - simple as pie.
I think there is likely some oxidation in the fuel feeds, emulsion tubes - somewhere you've got blockage. This raising the needle by 1 step should give you back the color you need now and in the weeks to come as air temps drop. When you get that garage, then you can really get in there and figure the problems out. Be sure to buy the right work stand. There is nothing like sitting on a stool and having your work conveniently at eye level --

Did you say only 4 bikes would fit?
