It's a 2004.....has a DR.D race series slip-on silencer and a ESR air box eliminator intake kit.......Right now i have it jetted with a 165 main jet,pilot jet is stock(i think) and the air screw turned out 2.5 turns.ESR said on their web page to leave the pilot jet stock,use stock needle,move the needle clip down to the 5th position from the top(which i did) and use a 195 main jet...but that was their setting @ sea level!!! also my bike will idle high,then when i ride it and stop, it want's to die if i don't give it gas,,,i'll adjust my idle screw to what i think it should be and i won't touch anything for a minute and it will just rev high on it's own or sometimes rev low.. I checked the throttle cable, it's fine and the carb is clean. what's going on??? I also have a 05' 400ex that has a FMF slip-on, K&N filter and run it with the air box lid OFF..How should i jet this one??? Any help is appreciated, THANK YOU
