Yes. That assumption would be correct.

Revving to 3,000 while stationary might produce the leak. If so, the float or needle is binding and the leak not caused by air speed.
Usually vibration helps to seat the needle, but strange things happen, mechanically speaking.

Then, may I take this opportunity to thank MCrenshaw?

I surmise from Rob's comment to my post that it may have come off differently than the way I meant it. I wasn't even trying to be a smartass. I appreciate any and all attempts to help answer my questions. I even appreciate smartass replies as long as they don't lead me astray on the question at hand.

So, thank you MCrenshaw and welcome to Boxerworks!

Yes, MCrenshaw, the majority opinion on this forum is that when it comes to intake systems on an airhead, stock is what works best.

Not many of us are running these on the track for the "big money".

"Most" of us. I do have individual air cleaner pods on my cafe racer. But that one doesn't have a leaky right carb.

But that is the "pretty" one, right?
(the one you use for all your hot chick model photo-ops)

Yes, there are exceptions, and Rev Light (Steve Hawkins) ran his R65 for YEARS successfully in England, of all places! (wet, that is).

Ongoing saga. I cleaned up the bike today to give it a test ride. Turned on the gas and big time leak from that same carb. I took off the bowl and pushed up the floats and the leak stopped. I now have it off the bike and the floats go with me to work tomorrow to be weighed.

I do realize that when I pushed up on the floats it probably put more pressure on the seat that shuts off the fuel. If it's not the floats causing the problem, well..............? They seem very light. Will weigh them.

The rubber on the tip of the needle can harden.

You could also try a float test. This is one of my sinkers at 16 or 17 grams. There should be be more like one third of the float above the surface. The float is suspended by the pivot as it is when mounted in the carb. If I didn't support the pivot end the float sank to the bottom of the jar.
