I recently got a 2004 KX250. I have not ridden it very much yet, still on it's first tank of gas. Yesterday I took it out continuing to break it in nice and easy... After about 20 minutes it fouled the original plug... I figured no big deal. I put in a new plug and away i went. About another 20 minutes of riding and it fouls the plug again. Only carried one spare. :eek:
The original was an NGK BR8EIS {or IES not sure} the second plug I used was a BR9ES. Do I need to run a Resistor type plug in this bike?
My other thought was to drain the rest of the gas out and put my own mix in. Any other thoughts?
