E-Series Jetting

1 post in this topic

I just put on a White Bros. E-Series exhaust (just the silencer not the head pipe)on my 99' YZ400. After doing this I now have a hesitation off throttle. This was not there with the stock exhaust. My guess is lean on the bottom. Has anyone else had experience jetting differences with the E-Series?
