Unclipped electrical connector and hit it with me air compressor out flew last weeks monsoon downpour! Result electrical cleaner and silicone grease to be safe and LCD results back to factory settings.The bike was awful stalled at starting,mega rich fuel settings,like it had kangaroo petrol in it,must have been shorting out so if you get these symptom try this,little black round plastic component on right side of throttle housing 57 plate xt660x:SPanikengun77:
