Gotta 1993 250r 2stroke that won't idle to save it's life, my life, or our rat dogs lives. With the choke on it will until it warms up and has been ridden then it'll die. But with the choke off, it won't idle at all. I have to keep blipping the throttle in order to keep the motor running. Also on an unrelated note, where could I get a heavier flywheel to make chugging around at low rpms? This is my woods bike as well.
