kx 125 plug fouling

[kx125kid]

MY KX 125 fouls plugs left and rite. once a day(or ride) i mix 40:1. i dont like drive slow. i dont let it idle. its carbon fouling i think cuz its all like black. i cleaned carb and reeds. ummmm. im almost posive that the jetting is stock. it has a weiseco piston and fmf silencer and thats it. the top end is kinda getting old. rite when i put the new top end in it i went a month on a plug then down to 2 weeks, 1 week, couple of days then 1 day. think it could be the top end. give me you thoughts. oh ya, i took off the cylinder to clean the piston and ports and power valve but and put new gaskets on and that didnt work, and i tryed br8es instead of br9es. give me your thoughts. peace
