Default Fixed check valve now bike runs like crap

Hi everyone, as the title says, i fixed the leaking check valve on my 2013 ‘72 changing the o rings. After putting everything back together, the bike now sputters and seems to lack fuel in low gears. Feels like it runs in 1 cylinder. If i WOT, it goes away. Any tips are appreciated.

Might be debris from old o ring at injectors.

The one o ring came out in one piece (fortunately). It’s the one that goes right below the thread.

Sounds odd that a FI issue would work under WOT and not lower throttle positions. Sounds like full fuel supply is available. You were working in the area of plug wires, perhaps you knocked one off?

It does sound odd. Plug wires are in place, although i never touched them. It idles fine although there is a hesitation when i accelerate a little as if it sucked air. Everything is connected correctly.
