I have no desire to replace them with the rubber ones for Suzi's, just want to reuse them more than a few times.

Super ideas there.
Those tiny plugs need to be finessed to get them out. Parallel jaw pliers may give a better grip and not damage them as the other types. Then there's the tiny-expensive o-ring, which must be squished very-carefully when putting the plug back in. They get damaged by the slightest sharp edge, if not pressed into the hole just right.

Some heat on the carb passage may assist removal of the plug.

Been through this set of carbs a few times, and the last was to install brand new slides. A recent re-jet was when the header went on, then last Spring after the head transplant. It has 40 pilot jets and 132.5 main across the four. Last week I put one
.50 mm washer/shim under 2 & 3 needles to enrich them a touch. These carburetors seem to be working great...
makes me wonder if changing over to VM33's would be a waste of time and money.

If obsolete, then why are people paying three times that for a set? Seems to me you made a good investment, dude!
I checked my spark plugs after riding awhile with the modified air box (cover/snorkel removed), and here is what they look like after raising the 2 & 3 jet needles 0.5 mm (one washer):
Maybe two washers

You sure it's not oil on those plugs? I'd get it back to lean and start from there.

Not oil, but possibly fuel from too-rich mixture. Should I start with the pilot screw adjustments, and then the jets if needed?
It starts up great, and runs strong. I do get some backfires on deceleration, if the throttle is shut quickly. But not so-much when easing it down. Would that be caused by the immediate shut off of fuel/air mix when the butterfly valves are closed quickly?

I know the mains were too big, being aftermarket didn't help. Went down one step. When I get home, I'll take a pic of what they look like today. Might have to go down on the pilots too. Did you raise the float level? Could be masking your readings.
