[QUOTE="dirt bike dave, post: 1429300, member: 18302"] That is a classic symptom of your valves being set too tight, i.e. not enough clearance between the top of the valve stem and the valve train. On your bike, the clearances tighten up with wear. When the motor gets hot, the clearances disappear. So the valves are not closing all the way when the motor is hot. This will cause it to stall at low rpm and not restart until it cools down. Usually it will be the exhaust valves (they get hotter), but check and adjust the intake valves as well. [/QUOTE]
