hi mate i found that my mille 2005 was awfull when riding through towns or going round roundabouts. it wanted to either konk out or spit me off....... no inbetween. i thought at this point i had made a mistake buying a twin! took it to my local aprilia bloke and he changed the mapping and tinkered with the throttel body.
sweet as a nut now, loads more confidence and loving it bro!
