hi was wondering what if any problems happen to kx125's from the year range 99-02 what do you guys see happen to them the most. I ask cause I'm looking at one and I had one before that had a grooved up clutch basket and to top it off the inner hub had a snaped off prong. so hopefully you guys can see my consern and skepticism. The guy claims to have just finished heat cycles and all new internals. fair dunlop tires and a full PC pipe. thanks guys for your imput
