    thank you

    Alen does it do it all the time or when shutting down your throttle ? it could also be a loose spark plug wire , double check all conntions ,& any wire's that might be laying agents the engine / pipes , & double check the spark plugs them selfs

    could be a setting at that fuel point in the Fuel pack, the Pak only adds fuel, you might need less than it's adding or more...

    Check all the wires and fittings, pipes etc make sure things are hooked up correctly, if so
    remove the fuel pack and go for a ride (just unplug it) see if the problem persists.

    bike will be too lean, probably means it was getting too much fuel

    I would talk with V&H about the issue and the RPM etc. Let them know you
    pulled the fuel pack and the problem was cured.

    You need the map fixed.
