    60# injectors or RRFPR or leave it alone??

    Heres my set up
    Valve train upgrade
    Riva ECU
    50# injectors
    X Series IC
    Rude 1 SC
    4" Kanaflex intake
    Green Hulk waterbox
    15/20 Solas
    160* thermostat

    Is it fine as it is as far as air/fuel? Should I go with the RRFPR or 60# injectors? How do I know where I'm at, and where I need to go?
    Thanks

    Lave it as it is. the riva ecu is meant to work with the 50 pounders if you go with the 60 pounders is going to go to rich at idle and the ski is going to run to rich on top end. you have a reliable set-up as it is so dont mess it up...IMHO..

    I would get a RRFPR and set it at 60lbs. Then you will be spot on at 11.9AFR.

    that would be the starting point and you can take it from there, if you would like to reach the max out of your pwc you need to see where is your A/F at ....good luck

    Is to mount a/f gauge and o2 sensor to be sure you are getting the max out of the engine in safe way.
    There is so many topics about where and how to install a/f meter

    Hi mstennes,

    Ideally, we would all check our A/F ratio, but the special equipment and knowledge needed may not be "in the cards". So, we turn to the advice and experience of many on this site to help guide us toward a "safe" set-up.

    As aha stated, your ski would most likely benefit from the addition of a RRFPR. I see you are up north where temps tend to stay on the cooler side, so adding fuel is probably a good thing.

    BTW... I agree... gotta have more cowbell
