Recently I bought the GPZ 100 RX second hand. My problem is, even after a thorough service, that as soon I drove 20km or so, i.e. when the engine is hot, it stalls when I have to stop on a traffic light and driving on in the first gear is a problem. Seems like as the engine is stottering. If I leave to cool down for 30 min or so, it´s fine again until it´s up. Anyone any idea how to solve my problem? Would anyone have a copy of a users manual for sale? Kind regards......Rudy
