I am new to the dirt rider forums. I have been around bikes as a kid. My son and I are getting into dirt bikes and riding together. My question is on the subject of o ring chains. I ride a 1996 KDX 200. What cleans o ring chains outside of gasoline? And what lube is good? All I have found is stuff (that I prefer to leave nameless) leave built up of dirt and a hard grease like substance. I want to take care of this bike and I need help and imput! :confused:
