    i have a 2000 ultra with a mirelli fuel injection all sensors except crank positioning sensor have been replaced . i have a power commander on it also . its been dynoed and was running great then for no reason it seems to be running lean at lower speeds , pops on deceleration and spits a little at a idle . is there any thing i can check ? thanks

    How does the bike run without the Power Commander attached?

    I had a 2000 RK with MM injection. I had pretty much the same problem as you. Turned out to be the bushings that support the butterfly rod was sloppy; letting air in. This was at about 60k on the clock.
