    Hesitation when giving Gas

    Qaxe, Yes indeed it is the bike. Thing is , when I lower idle with warm engine. It will not be enought when engine is cold. After 15 min rides idle is always going up my */- 1000 rpm. Thus I will try to fix idle with warm engine and let you know the results. Thanks
