Yes and No.
Yes, you can use most of the injectors made by different manufacturers, given the below conditions:
1) the injector is saturated type ( > 8 ohm resistense), not peak and hold type (requires different injector driver). By the way, for small engines, most injectors are saturated type. Because it is small and requires not as much fuel as trucks. Peak and hold are for those big flow rates, usually > 300cc/min.
2) You will have to make some mechanical mods, to fix the injectors on the throttles (replace the bungs we are using, and fab your own bungs). For this reason, it's a "No" to your question.
3) The injector size must be able to cover both high RPM and low RPM sides. 240cc/min is too big, and it's more than enough to cover the high RPM, but it will run tooo rich at idle (hitting the minimum pulse width of the injector).
Anyway, we have 128g (178cc/min) and 190g (264cc/min) injectors, same mechanical dimensions, and they can swap the original 80g injectors. Actually, without a label on the injector, you would not tell the difference.
We are using 2x128g injectors for Ninja 250r conversion across the board now, which will provide enough fuel at peak RPM.
