If I remember correctly- my old ZRX1200 picked up ..... *edit- just went back and looked- 16.6whp from pipe and jets.
Alain- you are giving the factory injection too much credit. It is NOT smart enough to 'calculate the correct/proper amount of fuel required - no less/no more.' It will not adjust for 100% of the air for any modifications done to the bike.
It is simply built to run correctly on a stock bike and hit an emissions target. It does NOT have a wideband O2 sensor from the factory. Just a plain old simple narrow band.
While it isn't as crude as old CIS or Digifant injection- it is still basic in it's operation to meet it's goal. Once the intake/exhaust is changed outside of it's initial design parameter, the fueling is no longer correct.
