true harold but its always the knowledgabe that should enlighten the ignorant.
Basically the second you modify the jetting or carb at all the oil injector provides completely the incorrect amount of oil regardless of anything else.
And to use it still would mean you never really know how much oil is going in, you have to calculate some mix ratio using your old and new jet sizes. When tuning, once u add the oil to the tank you can't take it out so you never have an accurate amount if you are still using the injector and swapping jets.
Furthermore IMO its less convenient to mix and fill the oil tank.
