I fouled 2 BR8EX plugs on my 96 KX250 in about an hour of riding. (The second plug-after I stalled the bike for a short break and restarted it, took off and just died while at about 1/2 throttle) The bike ran great for the longest time until now. It has a pretty recent top end and the only thing I did to it before riding was throw in a new filter. Is it possible to over oil the filter and foul the plug? I use FAB-1 spray (the blue stuff) and oiled it just a little more than average due to the lack of rain and lots of dust. The bike has been jetted and tuned from the guy I bought it from. He used to race it. I am also considering to raise the clip 1 notch (lower the pin) on the carb because the cylinder seems to load up pretty fast while cruising in low RPM's. Even when I grab the clutch and rev it every once in a while. It takes a good open trail and a few good cranks on the throttle to clean it out. Never had a prob with the plug until now, though. I do all trail riding. I mix synthetic 32-1. Already checked the carb and it's clean. Any thoughts or suggestions?
