Missfire between 1-2000 rpm

[Fazerjon]

Hi all just bought a 2000 fzs 600 as a non runner. Took carbs out, stripped ultrasonically cleaned, replaced all o rings. She now starts on the button but has a slight missfire under load or opening the throttle between 1-2000 rpm. Above 2000rpm the bike pulls cleanly all the way through the rev range. Before I strip the carbs down again does anyone have any ideas? I’ve trimmed the HT leads down by 10mm and set the TPS to 5k as per the manual. I still need to balance the carbs but not sure if it’s a good idea with the missfire, or could that be the reason it’s misfiring?
Any advice greatly appreciated.

check your idle speed. Idle should be 1150-1250. Then balance the carbs.
