Has anyone experienced the bar end stops coming loose? My first bike. They´ve been fine. Was when I got to work this morning. On my ride home BOTH weren´t right. Left fully loose. Like a bolt and rubber bungs. Managed to secure. But my throttle one keeps spinning and feels like there´s nothing to fix too. Any ideas how to correctly fasten this ? There´s a ten mm gap between chrome bar end and the throttle. Feels deliberately done to me but can´t fathom why? Any help greatly appreciated. Tia . Damo
