Hello to all,could I use the KDX for trail riding,with out fouling out spark plug's on a regular basis,sincerely.Labow

 

yeah, i race a kx125 but in the off season i trail ride and its fine. you just need to keep the revs up. if it starts to get boggy and unresponsive downshift til it winds and responds normally and you should have no trouble with fouling the plug.
