1993 GS500E. Full Yosh exhaust, stock airbox with new uni filter. Intake boots still supple, replaced intake o-rings with new OEM. Stock carbs so clean you could eat off of them, all new factory o-rings.
Based on a lot of research, replaced stock 37.5 idle jet with a 40 idle jet. Replaced stock main jet (122.5) with larger (127.5) to compensate for exhaust and uni-filter (may need to go larger, but figured I'd start there). Air mixture screw set to 3 turns out.
Fixed my runs-poorly-on-one-cylinder problem. Hit starter. Wham! Instant start with no choke, idle settled to a nice even 7K rpm. The idle speed screw has no noticeable effect on the idle, all the way in or all the way out.
Suggestions on where to start diagnosing?
