I recently bought a TS125 as my first bike to learn on and learn how to maintain. When I got it, it would run fine and idle fine, but yesterday it started idling wierd. It will start fine, but it idles super low, like maybe 700 rpm, and sounds like it is going to die. It wont die if it sits there, but if I rock the bike back and forth it dies right away. Since this has happened, it also will die while im driving it, if i pull in the clutch and dont have the throttle all the way on. Any body know what could be causing this? I tried adjusting the idle screw and its as high as it can go.
