I havent ridden my xr650r in a long time. Yesterday i took it for a stroll around the city streets. The bike when i get to red lights, turns off. Even after it has been warmed up. It just keeps shutting down. What I have to keep doing is giving it a little bit of throttle. If I increase the idle adjustment a little bit, the bike keeps going up in rpms even thou i am giving it gas? Any ideas?
