Sparkplug appetite

Does the insulator or center electrode look strange? It may be running hot =a lean fuel mixture or poor ventilation.

I used to have a problem like that with a Kawasaki two stroke. CDI ignitions don't like it when a plug loads up briefly and they will crack the plug's insulators in spite. First, run Seafoam in the gas to keep the carb and tank clean. Then spend the next 500 miles consciously not whacking the throttle open but rolling it on smoothly and see how the plugs last. I had a similar problem with a Lance 50cc scooter. In the end it, oddly enough, turned out to be crud in the gas tank stinking up the carb.
