KX500 Spark plug Question??

<< < (2/2)

arleybeer40:
I run a br7es and 32:1 premix and have never had problems with unless i run leaded race gas at the dunes. When i stop when the engines warm it wont start, like its flooded. I turn the gas off and hold the throttle open fires right up. Gotta remeber to turn the gas back on though. Hope this helps
