im in need of some direction here, since i bought my 99 yz400 used i have put a years worht of hard desert riding and several races on it, i think its time to check the internals of the motor and probably a top end, anyone have a general rule of thumb as to what i should replace or check, also it recently started puting out blackish smoke on start till its warmed up, the only diffenrce i did was put in the 2002 needle, could that be the culprit, thanks
