Paul, you have convinced me to have it done !! As regards the power commander I am not sure this will invalidate the warranty as it plugs into the existing wiring loom, no cutting etc and is no different to having a FIM Ultamap chip fitted which does the same job as such. My bike had the termi's etc fitted along with the chip etc, etc, and that was by an authorised dealer and they said nothing about the warranty being made invalid by this work! Besides, if the rockers have gone, the power commander will have had nothing to do with that ! Correct me if I am wrong. Dave |
