I added a new inline fuel filter which I think may be too restrictive, it's meant for a tractor so maybe I'll look into swapping that back. If it's the ignition coil I may replace it.
Good on the carb settings then.

No disrespect, but many a Ninja-owner has "gone through/cleaned/rebuilt/fixed" their carbs only to find there are still carb-related problems. Maybe not the case here.

There's not a lot of room for an inline fuel filter, and if it creates a low spot in the fuel system you can have delivery problems.

Pull the filter and see if that changes anything. Did you find a small filter at the carb inlet?

How much gas was there when you added 2 gal? If there was condensation in the tank, or the original gas was bad, adding fresh to it isn't going to make it good. Draining completely and refilling is the only way to know it's fresh.
