i have a 99 yz400, i have installed a White brothers E-series exhaust and a phat boy header to go with it i tried rejetting it once with bas results. right now it needs gas to stand and idles way high when it will idle. my local stomping grounds include i-5mx lacr raceway and lemon grove (piru) i also do a little pit of desert riding in california city. if anyone has any tips it would be greatly appreciated.
