................................................Here's another question: In general, would it be better to run newer carbs as older carbs than to run with older carbs? (By that I mean remove all the baggage, stripping it down to just gas IN and vacuum line to the petcock.).....................................

I've long said the change from the 2 circuit carbs to the 3 circuit carbs was the biggest performance change made to the GS500s as far as everyday riding goes.  The bike pulls stronger and smoother thru the mid range and all around in general except at the top end and also pulls from a lower rpm at the bottom end, needed 4k rpm to get the 97 pulling smoothly and my 02 pulled nicely from 3k rpm.

I rode both my old 97 that I had put 80k miles on and my almost new 02 with only about 4k on it back then for a while and the difference was obvious to me.  Yet that 97 with 80k miles on it still pulled a bit stronger on the top end.  I have 92k miles on the 02 now and never touched the carbs on either but my bikes never sit and dry out for long.  Could be there was a cam change too between the 2 and 3 circuit carb models but I've never been able to confirm that one way or the other.

I don't think you understood my question. Not asking about engine mods or milling out the engine. I don't know where that comment came from.

Mainly - can we just remove the crap on the newer carbs and run them in a simple way like older carbs: gas in and vacuum to the petcock.

The rest was comments on what I like on new wiring .vs. old wiring, and so forth.

Yes you can, it dont need the extra heft, clutter, and possibility to malfunction.
sorry it was late and I was rambling.

But, can you still detail the removal and parts of the blacktops?

I want to see if white tops can be made into black tops.

Send me a micrometer to borrow and I'll tank the valve cover and measure my lobes for you.
