I'll let the video do most explaining, but the background is that I cleaned and rebuilt the carbs on my 1999 Katana 750 earlier this year, set the pilot screws to 2.5 or 3 turns (forget which, but I recall going between 2 and 3 didn't really make a difference). I rode the bike for a bit; between it and my Vulcan 900 I much preferred the Kat when commuting, for the maneuverability and acceleration.
Anyway, I couldn't get it running for a couple months, then found somehow someone set the idle way high which of course would lean it out on startup. Fixed that a bit. On starting, it revs high, then settles to idle, 'choke' isn't very consistent, making things go wild, but it's either 3000-5000RPM or nearly dying. While warming up, it dies on any throttle, even with choke it seems.
So...pilot circuit still dirty? I don't know how it can be...I sprayed carb cleaner through all the passages (seeing it spray out the other ends) and blew them all out with air after. Is it possible for the passage to be partially blocked, but still allow a seemingly full-pressure spray of carb cleaner through?
Without further ado, here's the vid: https://www.youtube.com/watch?v=d41Ae_gE4_o
