Thanks that's a good common sense checklist.
This the repair kit you're talking of I think: https://litetek.co/Carb_Kit_Yamaha_FZS600_Fazer.html
I don't think it would do this with leaking fuel somewhere though. My issues are with the butterfly if it's staying open; I don't know why it would behave as it is if that isn't the case.
The settings: pilot screws are 2.5 out (I hope), what else is there to adjust other than balance and idle? Needle jets are all at the standard position (I hope).
I'm about to go and rip em out and see what's what. It's overwhelmingly likely I've done something stupid.
Update: had them off, checked everything. Can't see anything wrong. I have a spare set with seized pilot screws, which were good a month ago. So I put the removables from 3 and 4 from that into this set, switched the pilot screw for 1 & 3, and tried again. Exactly the same, 3 and 4 with the vacuum too high on the gauge, even with the tickover screw right out.
The butterflies are more open for 1 & 2 than 3 & 4. I'm starting to think it isn't the carbs, and I haven't screwed the spark plugs in properly or something. Or the carb rubbers I've got are spectacularly leaking. I didn't check with the carb cleaner or water spray, so I can try that tomorrow.
