YZ 125 2005 model I'll run the bike for roughly 40 minutes or so and the bike will die on me. FOULED PLUG! fak happened several times out on the trails. The original plug was a BR8EV i believe. I changed it out to a br9eg and it ran ok but the fouling started! i ran a br8eg i believe it was and it ran nice but the power didnt seem to cut in.. like it was revving out super quick. I've cleaned the carbs TWICE. I'm running stock jetting plus the needle clip in the middle position. running 44:1 what plugs are you guys running on a 05+ yz 125? maybe it's the plug or maybe i just over oiled the filter? dont think that could cause it to foul this bad.
