I have a 250ex with a kn airfilter and i just bought a new hmf full system and dynojet kit. what size jets should i use? does anybody have the same setup as me? and ive never rejetted before so i wanted to know how to get to the carb, i dont know where it is i havent taken it apart yet. do the instructions that come with the jet kit tell me what jets are recommended?
