    i took a look at it today i noticed the one barbed fitting on the top of the regulator is just open does this go to something to make it rising rate?

    Connect it to vacuum to get rising rate.

    I would say it depends on your AFR's. Did you install the FPR because you couldn't get enough fuel to the motor with the Powershot?

    I had my Riva FPR all last summer and it was static but I was close on top towards the end of the year when it got cool to being lean even with the red Powershot settings farily high. I will more than likely have to bump the fuel PSI a pound or two this year after initially checking AFR's.

    Unless you upgrade to the R3, then you may or may not need it.
