    Question Bad injectors?

    Does anyone have a test proceedure to find out if you have a bad injector? I have 42lb injectors but everytime I try to install them my RXP barely runs.

    All injectors are not the same, where did you get them from? Measure the resistance across the terminals.

    The injector are the 42# Rotax, the resistance on all of the injectors read 12.6, 12.7, 12.7. When I install them in my ski it just runs really rough. Any suggestions? My elevation in 3000 ft above sea level.

    check your stock injectors and I think you will find them to be about 4 ohms, I think you may have high impedance injectors that are not compatible.

    Ok - so I double checked my OHM readings off every one of the 42# injectors and they all read 12.6 or 12.7. Do I have the wrong injectors or what?
