i have an 87 moto4 200 and if i turn the handlebars all the way to the right while idling it stalls. any suggestions?

 

seems like some wiring needs to be re routed or the throttle line looked at, it must be pulling a wire out just slightly when turned, check to make sure no wiring is frayed and grounding it self out either and also make sure the wires have some slack in them to be able to turn the bars.
