All the Bonnies and Thruxtons came out of the factory with identical jetting, only the needles were changed for a richer AFR to take in to account the slightly larger CC and different cams of the 865's. Every carb'b bike in factory spec I've had on the dyno or linked to the LM-2 before mods, but with the AI disabled, shows a 12.0 - 12.4 AFR from around 2,500rpm to the rev limiter at full throttle, which is easily enough to take in to account an ethanol mix without the AFR going lean. This rich AFR ensures that where ever in the world and what ever the weather conditions, the bike won't ever be lean enough to cause running problems or damage the engine. No manufacturer of carb'd engines would release an engine running in a "notoriously lean" condition, that would be asking for trouble.
Having said this, I can see that for some owners if using an ethanol mix, minor adjustments may well be necessary for starting and smooth small throttle running as at part throttle the AFR is leaner.
Kreemsicle - You say you cleaned and oiled your filters a month ago. Is it possible you over oiled them ?
2 1/4 turns with 42 pilots will be way rich, see what it's like at one.
Wow! Lotsa sexist comments here. Not that I'm offended by them, BTW. I think it's all a matter of personality.
