has any ever had any bad luck with the JD recommend jetting setting that came with the jet kit? I have an 05 ktm 250sx and i dont know much about jetting just where the jets are how to replace them.
i got a JD kit for my 02 cr250. the suggested jetting was pretty close but i did have to mess with it a little before i got it spot on.
have you read through the jetting "sticky" at the top of the forum? there are some really great write ups floating around.
