My daughter bought a 2003 sportrax 400ex from a cousin bike wasn't running. cleaned the gas tank put a new carburetor on it new regulator new solinoid, battery, coil, and a new CDI box. after it gets to operating temperature if it dies or you kill it it will not restart until it cools off. the natural lights comes on but after it warms up the light goes out after you kill it or it dies will not start back till it cools off . anything at this point would be very helpful Thank you.
