Good you've a successful outcome with fueling and now running well.
For interest, the idle jet circuit on these runs a long way up into rev range when used on light throttle. Any impairment has quite significant effect on clean running for most speeds up to about 40mph ish. It'll give you a weak cylinder further out too as the main jet blends in with higher slide positions. Having the idle circuits impeccably clean is a big part of getting them running smoothly and consistent.
You're right. Lots of wrong info on the international site by socalled experts, who always come up with the same generic scheme. Already in the 80s an old Honda mec who owned a CB500 himself, had informed me on this and experiments I did, proved him right.
