i think im getting either a white bros. e series with header, or a FMF powercore 4 with the header that it comes with. Will i need to rejet after i put on these mods. and if so do u recomend getting profesionally done or can i do it myself and how? also, which pipe would u recomend? thanks

Yes you will have to re-jet after that. You can do it your self its real easy. take the carb. off and take the bottom drain plug off. The main jet will be right there. Take a small socket and unscrew it. Then put the new one in. MAke sure you dont over tighten it or under tighen it! Keep checking the color of the plug to make sure its not lean still. For which pipe.... I would choose the white bros. because accroding to the dyno they make a little bit more tourque and same h/p.

 

thanks
