[QUOTE="Fred T, post: 84274, member: 22413"] [b]MI Jetting[/b] I have the Rev pipe and air box mod to my newly purchased KDX 220. I run the stock 45 pilot jet, 145 main and needle on 2nd from top. air screw is about 3/4 turns out. My bike runs great in MI woods. I bought a 148 and 150 main but never installed them because the bike runs so good and plug readings look good. I don't hold it WFO much so as the weather warms up I figured the 145 main would be allright. As the fall approaches I will put the 148 main in it. I've been riding in upper 60 to 70 degree weather lately. Oh, btw I run the BR8ES plug too. [/QUOTE]
