Hey guys, I just purchased a 01’ 400k, well modified. Its got a pipe on it as well as a ton of protection mods (case saver, skidplate, bark busters, Rad guards, etc…). Well sorted bike, but the previous owner said he just couldn’t get the jetting right. I found the time to remove the carb and take out the jets and check them out. I also purchased the JD kit, snorkel removed, pipe installed. Bike will not idle, I have the throttle stop up really high to keep it alive, but it really wants to die at idle. There is also a fair amount of popping on deceleration. Old settings: MJ: 170 PJ: 50 Needle: Stock, Third Clip New Settings: MJ 165 PJ: 50 Screw 2.5 Turns out Needle: JD Blue 4th clip At sea level btw…. I am thinking that the pilot jet is too large and causing it not to idle. Am I right in this thinking? Is there anything I can do with the mixture screw to accommodate for this or should I just go out and buy the appropriately sized pilot jet?
