400ex jetting issues

Hello,

This is my first post here on the forum. I normally wouldn’t do this but I am in need of help. I recently purchased a dynojet kit for my 2005 400ex. I am running a big gun eco series clip on as well as a k&n intake. My quad used to run alright until I installed the stage one jet kit. Now, it will barely idle. I can get it running and it’s Got plenty of power it’s just idleing and getting it started. I called dynojet and they said that the main jet and needle have nothing to do with my idleing problem. Bottom line is my quad is running horrible since installing the kit. Any ideas? Any feedback is appreciated

Thanks
