Why would headers make the a/f ratio rich? In my (limited) experience with carborated motors (dirt bikes and quads), adding an aftermarket exhaust requires a larger main jet (more fuel). Since the headers will open up the exhaust (much like adding a Yoshimira to a TRX) wont that lean out the a/f ratio?

Thank you for the response.
