Hi there, Does anyone know the answer to this, please? My Pegaso 650 Cube only runs cleanly when the headlight is switched on, but will idle fine without the lights. I´m sure that wasn´t the case when I first bought it, but recently it misfires above 3000 revs unless high beam is selected, at least until it is at full running temperature - say after 6 miles or so. Any ideas? Cheers, Simon.
