Ive got a 2001 400ex with FMF Powercore IV and stock air filter. I bought it used this way and the carb was rejetted for the exhaust. I am about to add a Unifilter to go along with the exhaust and help it breathe better. Do you think it will be necessary to rejet the carb? I know the only way to tell is to plug test it but I kinda would like to know some opinions on what I might could expect that way I can change the filter at a time when the Honda store is open, otherwise I may put it off until Sunday. Please let me know your opinions.
Thanks
Mike
