I have this bike. and I need a little help. I bought this bike last week. I checked the spark cables, everything was clean. put in a new spark plug, and it ran perfect. then about 30 min into riding. back fired a couple times and died, my Brand new spark plug was fouled black. I checked the air ratio on the vacuum carb, 1 1/2 turns in. new plug ran perfect, for about 6-7 hours, then same thing, I am takeing a part the carb and cleaning it, and putting in a new fuel filter.

please any other suggestions would be handy
